Please see the answer in the picture attached below.
Hope this can help you. Have a nice day !
The reaction is: HCl + Na HCO3 → NaCl + H2CO3, which is already balanced.
Then the molar ratios are 1 mol HCL : 1 mol NaHCO3
You know the mass of NaHCO3 is 0.100 g, then you can find the number of moles using the molar mass of NaHCO3
molar mass of NaHCO3 is 23 g/mol + 1 g/mol + 12g/mol + 3*16g/mol = 84 g/mol
And the number of moles is: 0,100 g / 84 g/mol = 0,0012 mol of NaHCO3.
Then, from the ratio 1:1, you know that, at the titration point, the number of moles of HCl is the same: 0,0012 mol of HCl.
Now from the fomula of molarity you have: M = #of moles / V in liters
=> V in liters = # of moles / M = 0.0012 mol / 0.100 M = 0.012 liters
Answer: 0.012 liters of HCL
<u>Answer:</u> The solution will be an acidic solution when ammonium perchlorate is dissolved in water.
<u>Explanation:</u>
Salts are formed when an acid reacts with a base during a neutralization reaction.
- When a strong acid and a weak base reacts, it leads to the formation of acidic salt.
- When a strong base and weak acid reacts, it leads to the formation of basic salt.
- When a strong acid and strong base or weak acid and weak base reacts, it leads to the formation of neutral salts.
Ammonium perchlorate is formed by the combination of perchloric acid
which is a strong acid and ammonium hydroxide
which is a weak base.
So, the salt formed which is ammonium perchlorate is an acidic salt and its dissolution in water will make the solution acidic in nature.

Hence, the solution will be an acidic solution when ammonium perchlorate is dissolved in water.
Answer:
0.2g of hydrogen is needed to produce 1.80g of water
Explanation:

No. of moles of water
From given values,
Weight of water 
Molecular weight of water 
No. of moles of water
From equation, it is clear that 2 moles of water can be formed by 2 moles of 
Hence, 0.1 mole of water can be formed from 0.1 mole of 
Now,
No. of moles of
