List 4 kinds of hazards that are caused by Volcanoes.

The probability of observing at least one ICU admission, among the next six patients hospitalized for COVID-19 is 0.26491. Option A is correct.

The probability of not observing any ICU admission among the next six patients hospitalized for COVID-19:

Probability of not observing ICU admission = 1 - Probability of observing ICU admission

= 1 - 0.05

= 0.95

Probability of no ICU admission among the next six patients hospitalized for COVID-19:

Probability of no ICU admission in one trial = 0.95

Probability of no ICU admission in six trials (patients)

= 0.95 × 0.95 × 0.95 × 0.95 × 0.95 × 0.95

= 0.73509

Now, we can calculate the probability of observing at least one ICU admission among the next six patients hospitalized for COVID-19:

Probability of at least one ICU admission= 1 - Probability of no ICU admission

= 1 - 0.73509

= 0.26491

Therefore, the answer is A.

The percent composition of carbon in the given sample is 40.12%.

To calculate the percent composition of carbon, we need to determine the mass of carbon in the sample and divide it by the total mass of the sample, then multiply by 100.

Given:

Mass of fluorine (F) = 4.80 g

Mass of hydrogen (H) = 4.90 g

Mass of carbon (C) = 6.50 g

Total mass of the sample = 16.20 g

Mass of carbon in the sample = 6.50 g

Percent composition of carbon = (mass of carbon / total mass of the sample) * 100

Percent composition of carbon = (6.50 g / 16.20 g) * 100 ≈ 40.12%

Therefore, the percent composition of carbon in the sample is approximately 40.12%.

Answer:

A molecule can be made up of two atoms of the same kind:)

Explanation:

hope that helps:))

Answer:

Explanation:

A compound is a makeup of molecules.

When you make a compound, you are combining molecules. But when you make a molecule, you are not combining compounds, you are combining atoms.

Examples:

Atoms:

\(\mathrm{H}\) (hydrogen) and \(\mathrm{N}\) (nitrogen)

Molecules:

\(\mathrm{H_2}\) and \(\mathrm{N_2}\)

Compounds:

\(\mathrm{H_2SO_2}\) and \(\mathrm{NaCL}\)

Take a look at the Compounds and Molecules section. The \(\mathrm{H_2}\) in the example of a molecule is in one of the examples of the compounds, but the \(\mathrm{H_2SO_2}\) (THE WHOLE THING) is not in the molecule. This shows how every compound is a molecule, but every molecule is not a compound.

Rutherford's model of atom could not explain chemical properties as it did not make any mention as to how chemical changes take place.

These properties are defined as those properties which become evident during or after a chemical reaction after the identity of the substance is changed during chemical reaction.

These properties cannot be determined externally just by viewing the substance ,these change immensely after a substance undergoes a chemical change.These are used for identification of unknown substances and for building up chemical classifications.

The major chemical properties are flammability,toxicity,reactivity,acidity and heat of combustion.For a chemical property to be apparent , it is necessary that the structure of the substance is altered.

The enthalpy of the reaction as written is approximately 239,306 J/mol.

To calculate the enthalpy of the reaction, we need to use the heat released (2330 J) and the amount of sodium reacted (0.224 g) to determine the heat released per mole of sodium reacted.

The molar mass of sodium (Na) is 22.99 g/mol.

First, we need to calculate the number of moles of sodium reacted:

Number of moles of Na = Mass of Na / Molar mass of Na

Number of moles of Na = 0.224 g / 22.99 g/mol ≈ 0.00974 mol

Next, we can calculate the enthalpy change (ΔH) per mole of sodium reacted:

ΔH = Heat released / Number of moles of Na

ΔH = 2330 J / 0.00974 mol ≈ 239306 J/mol

Enthalpy (H) is a thermodynamic property that represents the total heat content of a system at constant pressure. It includes the internal energy of the system plus the product of pressure and volume. Enthalpy is often used to describe heat changes in chemical reactions, where the difference in enthalpy between the reactants and products determines whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). Enthalpy is typically measured in joules (J) or kilojoules (kJ).

I hope this helps you ^-^

Answer:

neutrons

Explanation:

Since we are told that O2 is the excess reactant, we need only to focus on C2H6, which will be our limiting reactant. Convert the mass of C2H6 to moles by dividing the mass by the molar mass of C2H6:

(5 g C2H6)(30.069 g/mol) = 0.1663 mol C2H6

Since C2H6 is the limiting reactant, its quantity will determine how much of each product is formed. We are asked to find the number of grams (the mass) of H2O produced. The molar ratio between H2O and C2H6 per the balanced equation is 6:2. That is, for every 6 moles of H2O that is produced, 2 moles of C2H6 is used up (intuitively, then, the number of moles of H2O produced should be greater than the number of moles of C2H6 consumed, specifically 3 times greater).

So, the number of moles of H2O produced would be (0.1663 mol C2H6)(6 mol H2O/2 mol C2H6) = 0.499 mol H2O. We multiply by the molar mass of H2O to convert moles to mass: (0.499 mol H2O)(18.0153 g/mol) = 8.987 g H2O.

Note: If significant figures must be considered, then the answer would be 8.99 g H2O.

When water is lost, but electrolytes are retained, the first thing that happens is that moves water from the ICF to the ECF.

The fluid inside of cells, also called the cytoplasm or cytosol, makes up about 60% of the water in the human body, totaling about 7 gallons. Organelles like the nucleus, endoplasmic reticulum, mitochondria, lysosomes, and Golgi apparatus are suspended in and supported by the ICF. Also found in the ICF are cellular building blocks like sugars, proteins, carbohydrates, and lipids.

ECFs are any body fluids that are not inside cells. The two main components of ECF are plasma and interstitial fluid (IF). The balance consists of cerebrospinal fluid, lymph, the synovial fluid in the joints, pleural fluid in the pleural cavities (lungs), pericardial fluid around the heart, peritoneal fluid in the peritoneal cavity (abdomen), and the aqueous humor of the eye. In mammals, milk is also considered an extracellular fluid.

The ICF has higher amounts of potassium, phosphate, magnesium, and protein compared to the ECF. The plasma has high concentrations of sodium, chloride, and bicarbonate, but lower levels of protein as compared to the ICF. While water moves passively via osmosis, sodium and potassium ions move in and out of cells using active transport ion pumps. The pumps are powered by adenosine triphosphate (ATP) to provide the energy to move the ions against their concentration gradients (i.e. sodium moves out of the cell and potassium is pumped in) and maintain the gradients inside and outside the cell.

Answer:

Chlorine is more likely to steal a valence electron from sodium.

Explanation:

Sodium is number 11 on the periodic table with one valence electron. Belonging to the first group, it's one of the alkali metal, which are known to be highly reactive. Chlorine is number 17 with seven valence electrons, and it's in the second-to-last group of halogens--also very reactive.

Considering that elements with one valence electron are just about 100% likely to give up electrons to reach a stable state, sodium would be the element that is more likely to lose its valence electron to chlorine. In other words, chlorine would be the electron thief.

Answer:

v = 10 m/s

Explanation:

Given: An object has a kinetic energy of 250 J and a mass of 5 kg

To find: Its velocity

Formula: \(KE = \frac{1}{2} mv^2\)

Solution: In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (\(\frac{1}{2}\) × m) multiplied by the velocity squared. In this case, an object with a mass of 5 kg (m = 5 kg) is moving at a velocity of 10 meters per second (v = 10 m/s), the kinetic energy is equal to 250 Joules, or (\(\frac{1}{2}\) × 5 kg) × 10 m/s².

Therefore, the velocity is v = 10 meters per second.

Electric lights do not come on unless their electrical circuit is closed circuit.

An electric circuit can be described as a path through which electric current flows. An electric circuit is a closed path in which the ends are joined making a loop. The flow of electric current can be only possible because of the closed circuit.

If an electric circuit is open circuit in which the flow of electrons is cut because the circuit will be broken. Electric current will not flow in an open circuit.

In a series circuit, there is one path for the flow of electrons and the entire circuit is closed or open. No current flow in case of a circuit break because the entire circuit is open.

Parallel Circuit is defined as a parallel type of electric circuit, different parts of the circuit are connected across many branches. Hence, electron flow takes place in several parts. If in one path a circuit breaks, electric current still flows in other paths.

Answer:

Generally speaking, water is good at dissolving ions and polar molecules, but poor at dissolving nonpolar molecules. (A polar molecule is one that's neutral, or uncharged, but has an asymmetric internal distribution of charge, leading to partially positive and partially negative regions.)

Water's polarity allows it to dissolve other polar substances very easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa.
