Answer: 1. 5
2H202 -> 2H2O + O2 ; 2 + 2 +1 = 5
Explanation:
Answer: Thus molarity of is 1.35 M
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus molarity of is 1.35 M
If the size is bigger than the em it is weaker <span />
Need to use the formula---> final amount= initial amount x (1/2)^(t/h), where t is time and h is half-life. time between noon and 2 pm is two hours. half life is 1 hour
final amount = 40.0 g x (1/2)^( 2 hours/1 hour)= 10 grams
Particles of gas are more scarcely placed as compared to that of liquid.
the intermolecular forces will be less in gaseous state and hence is less stable
