Answer:
7 moles
Explanation:
Given data:
Moles of hydrogen = 7 mol
Moles of water formed = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of water with hydrogen from balance chemical equation:
H₂ : H₂O
2 : 2
7 : 7
So in the presence of excess oxygen and 7 moles of hydrogen seven number of moles of water produced.
Answer:
1.008 grams
Explanation:
This numbers are either in grams per mole of atoms or atomic mass unit
Answer:
The answer to your question is No
Explanation:
I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.
Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.
If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.
Also, when I wash my clothes something similar happens.
These are some examples of the chemical reactions that happen daily but I think there are a lot more.
Answer:
Final volume = 0.103M x446ml/0.184m = 250ml
Explanation:
As time passes, the volume of solutions in the second beaker decreases and that in the first beaker increases. If we wait long enough, the final volumes and concentration in the beakers would be,
First beaker
Final concentration = 0.184M
Final volume = 0.296M x 284ml/0.184 = 457ml
Second beaker
Final concentration = 0.184M
Final volume = 0.103M x446ml/0.184m = 250ml
