What neutralizer is typically used with thio relaxers?.

Answer:

The particle theory is the belief that everything in our solar system and beyond is made of very small matter called atoms. The 10 mL is a matter in our solar system and even though we cannot see, there are millions- if not billions of smaller particles that make up the liquid. If you view the picture below, you can see that the particles in a liquid are close to one another, particles in a gas are far apart, and a particle in a solid is tightly pushed together. This gives them their distinctive shape. Since this is a liquid, this means that the particles are close together, but not very close. The particles glide over one another. If you want to have more space between the particles and expand the size of the liquid you can boil the water, however boiling the water turns it into gas and causing the liquid to evaporate. Freezing the liquid would cause the particles to be closer packed together, making a solid. The amount of liquid you have can not change. There is still 10 mL even when the liquid is frozen or when the liquid boils into vapor in the air. Therefore using particle theory, we can know that a shape can only expand or shrink when changing states of matter.

Answer:

The correct answer is - C) a different number of neutrons per atom.

Explanation:

Isotopes of an element are the same element and same atomic number but with different atomic mass and physical properties. The difference in their atomic mass occurs due to isotopes of an element have a different number of neutrons per atom.

The number of protons and the numbers of electrons are the same in the isotopes but only change occurs in the numbers of the neutrons. In isotopes of uranium U-233, U-235, and U-238 have the same number of protons but a different number of neutrons per atom.

The three nuclides U-233, U-235, and U-238 are isotopes because they have a different numbers of neutrons. Thus, option C is correct.

Isotopes of an element can be defined as the elements with the same atomic number but different mass numbers. The atomic number can be defined as the number of electrons of an atom.

The number of neutrons in an atom has been different per atom. Thus, option A is incorrect. Option C is correct.

Thus the three nuclides U-233, U-235, and U-238 are isotopes because they have a different numbers of neutrons. Thus, option C is correct.

One feature that decreases in size between Australopithecus and early members of the Homo genus is cranial capacity or brain size.

Australopithecus species, such as Australopithecus afarensis, had a smaller cranial capacity compared to early members of the Homo genus, such as Homo habilis. Cranial capacity refers to the volume of the braincase, which is an indicator of brain size. Australopithecus species had an average cranial capacity of about 400-550 cubic centimeters (cc), whereas early Homo species had larger cranial capacities ranging from about 600-800 cc.

The difference in cranial capacity between Australopithecus and early Homo species can be calculated by subtracting the average cranial capacity of Australopithecus (e.g., 500 cc) from the average cranial capacity of early Homo (e.g., 700 cc):

700 cc - 500 cc = 200 cc

The cranial capacity, and thus the brain size, increased between Australopithecus and early members of the Homo genus. This increase in brain size is thought to be associated with the evolution of more advanced cognitive abilities and technological advancements observed in early Homo species compared to Australopithecus.

Explanation:

In the titration of a 35.0 mL sample of 0.175 M HBr with 0.200 M KOH, the quantities are approximately 0.006125 moles of HBr and KOH, and 30.6 mL of KOH solution is required for complete reaction.

To determine each quantity in the titration of a 35.0 mL sample of 0.175 M HBr with 0.200 M KOH, we can use the concept of stoichiometry and the equation of the reaction between HBr and KOH:

HBr + KOH → KBr + H₂O

The number of moles of HBr in the 35.0 mL sample can be calculated using the formula:

moles HBr = Molarity * Volume (in liters)

moles HBr = 0.175 mol/L * 0.035 L

moles HBr ≈ 0.006125 mol

Since the balanced equation shows that the ratio between HBr and KOH is 1:1, the number of moles of KOH required for complete reaction is also 0.006125 mol.

The volume of 0.200 M KOH required can be calculated using the formula:

Volume KOH = moles KOH / Molarity

Volume KOH = 0.006125 mol / 0.200 mol/L

Volume KOH ≈ 0.0306 L

Converting the volume to milliliters:

Volume KOH ≈ 30.6 mL

Matter is anything that has mass and takes up space. It is the physical substance that makes up everything around us, including all the objects we can see, touch, and feel.

Matter is composed of tiny particles, such as atoms and molecules, that interact with each other through various forces to create the different forms of matter we observe. Matter exists in different states, including solid, liquid, and gas, depending on the arrangement and motion of its particles.

Thing 1, which has volume, is matter because it occupies space and has mass.

The mass percent composition of nitrogen in acetaminophen is 9.26 %.

The mass percent composition of an element is the percentage of the ratio of the molar mass of that element to the molar mass of the entire compound. Acetaminophen represented as C8H9NO2 is a drug that is used as a pain reliever.

First, we will calculate the molar mass of this compound. For this, we should know the mass of each element present in the compound.

mass of C = 12, mass of H = 1, mas of N = 14, mass of  O = 16.

Now, we will calculate the molar mass of acetaminophen

= 12*8+ 1*9+14*1+16*2

=  151 g

Now, we have to calculate the mass percent composition of Nitrogen.

The molar mass of nitrogen = 14g

The molar mass of the entire compound =  151 grams.

Mass percent composition of N =  (mm of N ÷ mm of C8H9NO2) ×100

=  (14/151) × 100 =  0.0926 × 100

= 9.26 %

Therefore, the mass percent composition of nitrogen in acetaminophen (C8H9N02) is 9.26%.

Answer:

cuz the liquid inside it could get in the machine

Explanation:

liquid water For example, the limited temperature range of liquid water (0°C–100°C) severely limits its use. Aqueous solutions have both a lower freezing point and a higher boiling point than pure water.

How hot (or energetic) a substance or radiation is can be quantified by a physical value called temperature.

There are three different types of temperature scales: those like the SI scale that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron in a body; those that only rely on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are defined by actual empirical properties of particulates rather than by theoretical principles.

Temperature is gauged using a thermometer. It is calibrated using a variety of temperature scales that historically defined themselves using various reference points and thermometric materials. The most widely used scale is the Celsius scale, previously called as "centigrade."

To find the number of moles of hydrogen produced from 10.0 moles of aluminum, you need to balance the equation for the reaction between aluminum and sulfuric acid.

Step 1: Balance the equation:

2Al + 3H2SO4 --> Al2(SO4)3+3H2

Step 2: Determine the stoichiometric ratio of moles of hydrogen produced per mole of aluminum:

From the balanced equation, 3 moles of hydrogen are produced for every 2 moles of aluminum.

Step 3: Calculate the number of moles of hydrogen produced:

If you start with 10.0 moles of aluminum, then the number of moles of hydrogen produced would be 3 * (10.0 moles of Al / 2 moles of Al) = 15 moles of hydrogen.

The pH of the solution after the addition of 100.0 mL of LiOH is 12.95.

pH (potential of Hydrogen) is a measure of the acidity or alkalinity of a solution, with a value of 7 being neutral. It is measured on a logarithmic scale from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. Solutions with a pH lower than 7 are considered acidic and solutions with a pH higher than 7 are considered alkaline.

The pH of the solution after the addition of 100.0 mL of LiOH can be calculated using the Henderson-Hasselbalch equation.
pH = pKa + log([base]/[acid])
Where pKa is the acid dissociation constant for HClO₄, which is 3.45, and [base] and [acid] are the concentrations of the base (LiOH) and acid (HClO₄), respectively.
Plugging in the values, we get:
pH = 3.45 + log(0.27/0.18)
pH = 12.95
Therefore, the pH of the solution after the addition of 100.0 mL of LiOH is 12.95.
