<u>Answer:</u> The nuclear fission reaction of U-234.043 is written below.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given fission reaction:
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
234.043 = 137.159 + A + 3(1.0087)
A = 93.858
Now, the chemical equation becomes:
Hence, the nuclear fission reaction of U-234.043 is written above.
Answer: The percentage composition of hydrogen in the given compound is 15%.
Explanation:
To calculate the percentage composition of hydrogen in a compound, we use the formula:
Where,
Mass of hydrogen = 41.4 grams
Mass of compound = 276 grams
Putting values in above equation, we get:
Percentage composition of hydrogen in a given compound = 15%
Answer:
Molarity is halved when the volume of solvent is doubled.
Explanation:
Using the dilution equation (volume 1)(molarity 1)=(volume 2)(molarity 2), we can demonstrate the effects of doubling volume.
Suppose the starting volume is 1 L and the starting molarity is 1 M, and doubling the volume would make the final volume 2 L.
Plugging these numbers into the equation, we can figure out the final molarity.
(1 L)(1 M)=(2 L)(X M)
X M= (1 L x 1 M)/(2 L)
X M= 1/2 M
This shows that the molarity is halved when the volume of solvent is doubled.
