To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.6-L bulb, then filled
snow_tiger [21]

Answer:

The chemical formula of the gas is N_2.

Explanation:

The difference between the container with gas and empty container is equal to the mass of the gas.

Let the gas be X_2

Mass of the gas = m

Molar mass of diatomic gas = M

Pressure of the gas = P = 1.80 atm

Volume of the gas = V = 4.6 L

Temperature of the gas= T = 27.0 C = 27.0 + 273 K = 300 K

Moles of diatomic gas = n = \frac{m}{M}

Using ideal gas equation:

PV=nRT

PV=\frac{m}{M}RT

M=\frac{mRT}{PV}=\frac{9.5 grams \times 0.0821 atm L/mol K\times 300 K}{1.80 atm\times 4.6 L}=28.26 g/mol\approx 28 g/mol

Atomic mass of the element X = \frac{28 g/mol}{2}=14 g/mol

The element is nitrogen and the diatomic gas is N_2.

What would the total surface area be if our large cube were divided into 8000 cubes with each side having a length of 1 cm?
ANEK [815]

Answer:

48 000 cm^2

Explanation:

8000      1cm cubes

 each 1 cm cube side is  1 cm^2   and there are six sides to the cube , so each cube has   6 cm^2  surface area

  and there are  8000 of them     8000 * 6 cm^2 = 48 000 cm^2

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.

Explanation:

Credit goes to @znk

Hope it helps you :))
