V(H2)

V(H2)=Vm*n=22,4*10=224 л

Answer 2

To find the volume of hydrogen gas (H2) produced when 10 moles of water (H2O) react, we need to know the balanced chemical equation for the reaction.

The balanced chemical equation for the reaction between water and hydrogen gas is as follows:

2 H2O(l) → 2 H2(g) + O2(g)

From the balanced equation, we can see that 2 moles of water produce 2 moles of hydrogen gas. Therefore, 1 mole of water produces 1 mole of hydrogen gas.

Since we have 10 moles of water, we can directly conclude that 10 moles of water will produce 10 moles of hydrogen gas.

Now, to calculate the volume of hydrogen gas (H2), we need to know the conditions (temperature and pressure) under which the reaction is occurring. Additionally, we'll require the ideal gas equation to relate the number of moles of gas to its volume.

The ideal gas equation is given by:

PV = nRT

where: P = pressure V = volume n = number of moles R = ideal gas constant (8.314 J/(mol K)) T = temperature in Kelvin

Without knowing the temperature and pressure, we cannot determine the exact volume of hydrogen gas. If you provide the temperature and pressure, I can help you calculate the volume of hydrogen gas using the ideal gas equation.
