What elements are in NaC2HO4 and how many atoms are in each element

JulijaS [17]

Answer:

Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.

A + B ⟶ Product

Particles: 6 8 6

If six A atoms form six product molecules, each molecule can contain only one A atom.

The formula of the product is ABₙ.

If n = 1, we need six atoms of B.

If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.

Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.

We expect the enthalpy of cumbustion of two isomers to be _________. The molecular formulas of two molecules are _____, so the b

Alex777 [14]

Answer:

We expect the enthalpies of combustion of two isomers to be different.

The molecular formular of the two molecules are very similar.

So the balanced chemical equation for the two combustion reactions are the same.

Explanation:

In calculation of the combustion enthalpiesfrom the isomers of the products and reactant.

The difference will be in the standard enthalpies of formation of the two combustion products.

The rod-shaped n- octane has vibrational and rotational motion possible more than the almost spherical neoprene.

A gas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. It required 10

masya89 [10]

<u>Answer:</u> The molar mass of unknown gas is 367.12 g/mol

<u>Explanation:</u>

Rate of a gas is defined as the amount of gas displaced in a given amount of time.

$\text{Rate}=\frac{V}{t}$

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

$\text{Rate of effusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}$

So,

$\left(\frac{\frac{V_{X}}{t_{X}}}{\frac{V_{O_2}}{t_{O_2}}}\right)=\sqrt{\frac{M_{O_2}}{M_{X}}}$

We are given:

Volume of unknown gas (X) = 1.0 L

Volume of oxygen gas = 1.0 L

Time taken by unknown gas (X) = 105 seconds

Time taken by oxygen gas = 31 seconds

Molar mass of oxygen gas = 32 g/mol

Molar mass of unknown gas (X) = ? g/mol

Putting values in above equation, we get:

$\left(\frac{\frac{1.0}{105}}{\frac{1.0}{31}}\right)=\sqrt{\frac{32}{M_X}}\\\\M_X=367.12g/mol$

Hence, the molar mass of unknown gas is 367.12 g/mol

A 8.5-liter sample of a gas has 1.2 mole of the gas. if 0.65 mole of the gas is added, what is the final volume of the gas? temp

stira [4]

13 liters is the correct answer

13 liters is the final volume of the gas when the temperature and pressure remain constant.

v1/n1 = v2/n2

where,

v1 = initial volume = 8.5 liter

n1= initial mole of gas = 1.2 mole

n2= final mole of gas = 1.2+0.65= 1.85 mole

v2= final volume = ?

8.5 L/1.2 mol = v2/1.85 mol

7 L x 1.85 mol = v2/1.85 mol x 1.85 mol

13 L = v2

v2= 13 liter

A mole is an SI unit used to measure significant numbers of subatomic particles, such as atoms, molecules, or smaller particles.
Any substance has an Avogadro number of molecules in a mole.
The value of the Avogadro number is 6.02214076 × $10^{23}$ .

22.4 L

At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.

<h3>What makes something a mole?</h3>

Chemists use the term "mole" because atoms, molecules, and other particles are all very small and require a large amount to even weigh them.
A mole is a measurement of the number of particles present, not their mass.
