The following equation can be balanced by multiplying the appropriate integers on either side:

Ca₃(Po₄)₂ + 4H₃PO₄ ⇒  3Ca(H₂PO₄)₂

In a balanced chemical equation describing a reaction, all of the reactants and products are represented in precise stoichiometric ratios, where the amounts of each element must match on both sides.

The example that is given serves as a combo reaction example. The phosphate group can be balanced by multiplying by 4 with H3PO4, and the number of calcium in the product side of the equation can be balanced by multiplying by 3.

As a result, the balanced chemical equation above has 6 phosphate groups, 3 calcium ions, and an equal number of hydrogens on each side. H3PO4 has a coefficient of 4.

Answer:

569K

Explanation:

Q = 3.5kJ = 3500J

mass = 28.2g

∅1 = 20°C = 20 + 273 = 293K

∅2 = x

c = 0.449

Q = mc∆∅

3500 = 28.2×0.449×∆∅

3500 = 12.6618×∆∅

∆∅ = 3500/12.6618

∆∅ = 276.4220

∅2 - ∅1 = 276.4220

∅2 = 276.4220 + ∅1

∅2 = 276.4220 + 293

∅2 = 569.4220K

∅2 = 569K

When the temperature is increased, there is the increase in thermal energy of the system. The final temperature of the iron in kelvins is 570 K.

The energy is the ability to do work.

Given is the energy Q = 3.5 kJ = 3500 J, mass of sample m = 28.2 g, specific heat of iron Cp = 0.449 J(g•K).

The initial temperature in kelvins is T1 = 20°C = 20 + 273 = 293K

The heat is related to the temperature difference as

Q = m c ∆T

Substitute the values into the expression,

3500 = 28.2 × 0.449 × ∆T

3500 = 12.6618 × (T2 -T1)

T2 - T1 = 276.4220

T2 = 276.4220 K +293 K

T2 = 569.4220K

The temperature of the iron is approximately 570 K.

Thus, the final temperature of the iron in kelvins is 570K.

Answer:3

Explanation:

In this question we have two dilutions occurring, for both cases we will use the dilution formula, which says that the initial concentration and volume of a solution must be equal to the final concentration and volume of the solution, we can better understand that formula presenting it to the question:

M1 * V1 = M2 * V2

where:

M1 = initial molar concentration

V1 = initial volume in liters

M2 = final molar concentration

V2 = final volume in liters

Now let's see what happens in our first dilution:

1.60 M * 0.075 L = M2 * 0.278 L

M2 = 0.43 M, this is the first final concentration

Now we have a solution with 0.43M and 278 mL

In the question we take 139 mL of the 0.43 M solution and add 193 mL, therefore having 332 mL as final volume, let's use the formula again

0.43 M * 0.139 L = M2 * 0.332 L

M2 = 0.180 M as final concentration

8) it has a boiling point around 35°

Explanation:

The following action will increase the equilibrium concentration of an inert gas (such as n2) in water: decreasing the pressure of the gas above the liquid. On the other hand, increasing the volume of water and decreasing the temperature of the water would not affect the equilibrium concentration of the inert gas in the water. Therefore, option 1 and 2 are incorrect.

When an inert gas such as nitrogen gas (N2) is added to water, it is not soluble in the water. As a result, equilibrium is established between the gaseous nitrogen and the nitrogen dissolved in the water.The concentration of an inert gas in water will increase if the pressure of the gas above the liquid is reduced. Because the gas will move toward the area of low pressure, more gas molecules will be able to dissolve into the water when the pressure above the water decreases.On the other hand, increasing the volume of water and decreasing the temperature of the water would not affect the equilibrium concentration of the inert gas in the water. Therefore, option 1 and 2 are incorrect.

The oxygen content of a water column can be seen to vary with depth in the image what causes oxygen levels to rise at great depths

At the deepest levels, there is frequently an increase in dissolved oxygen below the oxygen minimum layer. Since lower temperatures and higher pressure increase the solubility of dissolved gases, this bottom water is typically colder and under much greater pressure than the surrounding surface water.

What is pressure at depth ?

The relationship between pressure and depth is inversely proportional. This is a result of the larger water column pressing down on an object that is submerged. In contrast, pressure drops as items are raised and the depth is lowered. At sea level, a force of 14.6 pounds is applied to every square inch of your surface. For every 10 meters of sea depth, the pressure rises by approximately one atmosphere. The pressure will be about 500 atmospheres, or 500 times more than the pressure at sea level, at a depth of 5,000 meters.

Among the options given, the hydrogen atom (H) is not one of the four groups attached to the alpha-carbon.

In an amino acid, the central (alpha) carbon is indeed bonded to four groups. These four groups are:

Amino group (-NH₂): This group consists of a nitrogen atom bonded to two hydrogen atoms. It is called the amino group and gives amino acids their name.

Carboxyl group (-COOH): This group consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-OH). It is called the carboxyl group and is responsible for the acidic properties of amino acids.

Hydrogen atom (H): A single hydrogen atom is also attached to the central carbon.

Side chain (R group): The fourth group attached to the alpha-carbon is the side chain, also known as the R group. The side chain varies among different amino acids and gives each amino acid its unique properties.

Therefore, among the options given, the hydrogen atom (H) is not one of the four groups attached to the alpha-carbon.

Answer:

6.72*10¹²= 6,720,000,000,000 in standard form.

Explanation:

Scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a * 10ⁿ

 where:

In this case 12 is a positive number, so the decimal point is shifted to the right 12 places.

So, 6.72*10¹²= 6,720,000,000,000 in standard form.

The volume of carbon monoxide gas collected is approximately 18.34 liters.

To calculate the volume of carbon monoxide gas, we need to use the ideal gas law equation:

PV = nRT

Where:

P = Pressure (in atm)

V = Volume (in liters)

n = Number of moles

R = Ideal gas constant (0.0821 L·atm/mol·K)

T = Temperature (in Kelvin)

First, we need to convert the temperature from Celsius to Kelvin:

T (Kelvin) = T (Celsius) + 273.15

T (Kelvin) = 17.0 + 273.15

T (Kelvin) = 290.15 K

We are given the number of moles (n) of carbon monoxide gas as 788 mmol, which we can convert to moles by dividing by 1000:

n (moles) = 788 mmol / 1000

n (moles) = 0.788 moles

Now we can substitute the values into the ideal gas law equation and solve for the volume (V):

PV = nRT

V = (nRT) / P

V = (0.788 moles * 0.0821 L·atm/mol·K * 290.15 K) / 1 atm

Calculating the volume:

V = 18.34 L

Therefore, the volume of carbon monoxide gas collected is approximately 18.34 liters.
