Question

N(H2O)=10 мольНайти: VH2​

Answer 1

Объяснение:

V(H2)=Vm*n=22,4 л/моль * 10 моль=224 л

Answer 2

To find the volume of hydrogen gas (H2) produced when 10 moles of water (H2O) are decomposed, we need to use the balanced chemical equation for the decomposition of water into hydrogen gas and oxygen gas:

2 H2O(l) -> 2 H2(g) + O2(g)

From this equation, we can see that 2 moles of water (H2O) produce 2 moles of hydrogen gas (H2). So, we can set up a proportion to find the volume of hydrogen gas (VH2) produced:

(10 moles H2) / (2 moles H2) = (VH2) / (1 mole H2)

Now, let's solve for VH2:

VH2 = (10 moles H2 * 1 mole H2) / 2 moles H2 VH2 = 10 moles H2 / 2 VH2 = 5 moles of H2

So, 5 moles of hydrogen gas will be produced from the decomposition of 10 moles of water. The volume of hydrogen gas (VH2) will depend on the temperature and pressure at which the reaction occurs. If you have the temperature and pressure information, you can use the ideal gas law (PV = nRT) to calculate the volume of hydrogen gas.
