Answer:
Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.
Explanation:
By the reaction
H2+ 1/2 O2 → H2O
Moles of O2 = 5.2\32
⇒1 mole of O2 produce 1 mole of H2O
1 mole O2 will produce 2 mole of H2O
Therefore, 5.2\32 mole will produce 
⇒ Molecules of H2O will be
= 
= 1.956×10^22 moleculesof H2O.
Answer:
phsical
Explanation:
it is a phisical cuz your only changing the shape not the chemical structure
I think the answer A or C
<em>Calculate the molar fraction of NaClO in a commercial bleach solution that contains 3.62% by mass of NaClO in water</em>
<em />
<h3>Further explanation</h3>
convert mass to mol
mol NaClO (MW=74.5 g/mol) :
mol H₂O (MW= 18 g/mol) :
Total mol :
0.0486 + 5.354 = 5.4026
mol fraction of NaClO :
It can absorb thermal energy without a large change in temperature.
