Thank you for posting your question here. Below is the solution:
HNO3 --> H+ + NO3-
<span>HNO3 = strong acid so 100% dissociation </span>
<span>** one doesn't need to find the molarity of water since it is the solvent </span>
<span>0M HNO3 </span>
<span>1x10^-6M H3O+ </span>
<span>1x10^-6M NO3- </span>
<span>1x10^-8M OH-.....the Kw = 1x10^-14 = [H+][OH-] </span>
<span>you have 1x10^-6M H+ so, 1x10^-14 / 1x10^-6 = 1x10^-8M OH- </span>
<span>1x10^-6 Ba(OH)2 = strong base, 100% dissociation </span>
<span>1x10^-6M Ba2+ </span>
<span>2x10^-6M OH- since there are 2 OH- / 1 Ba2+ </span>
<span>0M Ba(OH)2 </span>
<span>5x10^-9M H3O+</span>
Answer: The heat absorbed by the water is 52.823 J.
Explanation:
Given: Mass of metal = 5.05 g
Specific heat of water = 4.184
Initial temperature =
Final temperature =
Formula used to calculate heat absorbed is as follows.
where,
q = heat
m = mass of substance
= initial temperature
= final temperature
Substitute the values into above formula as follows.
Thus, we can conclude that heat absorbed by the water is 52.823 J.
Answer:
B. A tertiary alcohol; a secondary alcohol
Explanation:
Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl group.
Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary) varies depending on which it reacts with.
2-butanone is a ketone.
Ketones reacts with Grignard reagent to form tertiary alcohol
Butanal is an aldehyde.
Aldeyde reacts with grignard reagent to form Secondary alcohol
The answer is; Tertiary alcohol; Secondary alcohol
Answer:
Explanation:
Hello!
In this case, since the reaction between calcium hydroxide and hydrochloric acid shows a 2:1 mole ratio between them:
We need to use the following mole ratio:
That can be written in volumes and concentrations:
Thus, we solve for the volume of HCl as it is the unknown:
Therefore, we plug in to obtain:
