Answer:
oxidation number is correct!! :)
Explanation:
Answer: 8.57 ml of KOH is required to reach the equivalence point.
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 8.57 ml of KOH is required to reach the equivalence point.
1 mole => 6.023 x 10^23 molecules
x => 8.5 x 10^25 molecules
x = 8.5x10^25/ 6.023 x 10^23 = 141.1
Do you want this equation balanced?
If so, it would be
SiCl4 + 2H2O ---> SiO2 + 4HCl
Answer:Answer:5.95 LExplanation:V1/V2 = T1/T24.82 L/V2 = 243.1K/300.1KV2 = 4.82*300.1/243.1 L = 5.95 L
Explanation: The volume of the balloon is 400 m3. To what temperature must the air in the balloon be heated before the balloon will lift off. (Air density at 10 oC is 1.25 kg/m3.)
