Since there are given data of two reagents, we need to obtain which of reagents are surplus.
0.3618 mol C4H4 - x mol O2
1 mol C4H4 - 5 mol O2
that means that there are too much O2 gas (by 0.009 mol)
so we continue counting using C4H4 data
0.3618 mol C4H4 - x mol H2O
1 mol C4H4 - 2 mol H2O
Mw(H2O)=2×1+16=18 g/mol
n=m/Mw
m=n×Mw
answer:13.0248 grams of H2O
2 ways to do this
a. find %Cl in CaCl2
2 x 35.45g/mole = 70.9g Cl
70.9g Cl / 110.9g/mole CaCl2 = 63.93% Cl in CaCl2
0.6963 x 145g = 92.7g = mass Cl
b. determine moles CaCl2 present then mass Cl
145g / 110.9g/mole = 1.31moles CaCl2 present
2moles Cl / 1mole CaCl2 x 1.31moles = 2.62moles Cl
2.62moles Cl x 35.45g/mole = 92.7g Cl
Answer:
Chlorophyll
Explanation:
Photosynthesis is the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.
Answer:
<h2>The answer is 4 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
a is the acceleration
f is the force
m is the mass
From the question
f = 20 N
m = 5 kg
We have
We have the final answer as
<h3>4 m/s²</h3>
Hope this helps you
