True:
The result is two genetically identical daughter nuclei.
If the object is denser then the substance it's in, it will sink. If the object is less dense than the substance, it will float.
Answer:
The van't Hoff factor of the solute is 1.51
Explanation:
Step 1: Data given
Molality = 0.710 molal
The aqueous solution freezes at − 2.00°C
Freezing point depression constant of water = 1.86 °C/m
Step 2: Calculate the van't Hoff factor
ΔT = i*Kf * m
⇒ with ΔT = The difference between the feezing point of pure and solution = 2.00°C
⇒ i the van't Hoff factor = TO BE DETERMINED
⇒ Kf = Freezing point depression constant of water = 1.86 °C/m
⇒ m = the molality of the solution = 0.710 molal
2.00 = i * 1.86 * 0.710
i = 1.51
The van't Hoff factor of the solute is 1.51
Given question is incomplete. The complete question is as follows.
Balance the following equation:
Answer: The balanced chemical equation is as follows.
Explanation:
When a chemical equation contains same number of atoms on both reactant and product side then this equation is known as balanced equation.
For example,
Number of atoms on reactant side:
H = 5
P = 1
O = 6
Ca = 1
Number of atoms on product side:
H = 6
P = 2
O = 9
Ca = 1
In order to balance this equation, we will multiply by 2 on reactant side and we will multiply by 2 on product side. Hence, the balanced chemical equation is as follows.
