san4es73 [151]

Answer:

1.8 moles of O₂

Explanation:

The balance chemical equation for said double replacement (photosynthesis) reaction is as follow;

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

According to balance chemical equation,

6 moles of O₂ are produced by = 6 moles of CO₂

So,

1.8 moles of O₂ will be produced by = X moles of O₂

Solving for X,

X = 1.8 mol × 6 mol / 6 mol

X = 1.8 moles of O₂

Stoichiometric problems in which moles are given and moles or other reactant or product asked are the simplest problems. One should only write the balanced chemical equation and perform above method to find the required moles.

Hydrogen peroxide can decompose to water and oxygen by the following reaction

mestny [16]

To begin calculating, there is one thing you need to remember : $1 mole of H2O2=34.0148 g$
Then we have $5.00g of H2O2=5/34.0148=0.146995$
As you know decomposition of 2moles now has prodused <span>196kj
So, </span><span>q is made due </span> $0.146995 moles of H2O2$ $=(-196/2)*0.146995=-14.40551Kj$
I'm sure it will help.
