Answer: Potassium perchlorate
Explanation:
Answer:the number of moles represented by 3.0 x 10^24 atoms of Ag is 0.500mol 0.500 m o l .
Explanation:
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
first determine the equation. KHP is a monoprotic acid, so it reacts with NaOH in a 1:1 ratio.
<span>a) HKC8H4O4 + NaOH → NaKC8H4O4 + H2O </span>
<span>This allows you to calculate the molarity of NaOH, from the equation V1M1n2 = V2M2n1 </span>
<span>Molarity times volume will give you the number of moles of acid. You can work this out by dividing the mass used by the molar mass. For this question, you will have 1.0115/204.2285 moles KHP, so this value can be substituted for V1M1 in the equation. You need 38.46 mL of NaOH to titrate all the acid, so this will be V2. Now you find M2. </span>
<span>b) 1.0115/204.2285 × 1 = 38.46 × M2 × 1, so M2 = 0.0001288M </span>
<span>Now go on to part 3. Here, you use a similar calculation. The acid and base react in a 1:1 ratio, so n1 = n2 = 1. M2 = 0.1905 and V2 = 25.62. V1M1 will be calculated. </span>
<span>V1M1 × 1 = 25.62×0.0001288×1 = 0.003299856 </span>
<span>Now mass divided by molar mass = V1M1, so molar mass = mass/V1M1. </span>
<span>1.2587/0.003299856 = 381.44 g/mol</span>
It’s either A or B, Sorry, I’m really not sure..
Answer:
5.34 moles of 
are required to produce 3.56 mol of 
.
0.83 moles of water react with 2.5 moles of .
Explanation:
i) 
Moles of we want to produce = 3.56 moles
According to reaction, 2 moles of are obtained from 3 moles of
Then 3.56 moles of will be obtained from :
of
5.34 moles of are required to produce 3.56 mol of .
ii)
Moles of = 2.5 moles
According to reaction,3 moles of reacts with 1 mole of 
,then 2.5 moles of will react with :
of
0.83 moles of water react with 2.5 moles of .
