Electron has the smallest mass
Answer:
Explanation:
We are given the percent composition: 22.5% phosphorus and 77.5% chlorine.
We can assume there are 100 grams of this compound. We choose 100 because we can simply use the percentages as the masses.
Next, convert these masses to moles, using the molar masses found on the Periodic Table.
- P: 30.974 g/mol
- Cl: 35.45 g/mol
Use the molar masses as ratios and multiply by the number of grams. 
Divide both of the moles by the smallest number of moles to find the mole ratio.
The mole ratio is about 1 P: 3 Cl, so the empirical formula is written as:<u> PCl₃</u>
Answer:
400 ml at 20⁰C
Explanation:
VP ∝ Temp => Increasing temperature increases VP or decreasing temperature decreases VP. VP is independent of the quantity of liquid in consideration. Therefore, the sample at the lower temperature would have the lowest VP; i.e., 400-ml at 20⁰C.
Answer:
Exothermic reaction.
Explanation:
From the question given, we obtained the following:
The equation for the reaction:
A —> C
From the diagram given in the question above, the reactant, A has a higher energy than the product, C. This simply indicates exothermic reaction as the enthalphy change, ΔH will be negative for the reaction.
Enthalpy change, ΔH is simply the difference between the heat of product, Hp and the heat of reactant, Hr i.e
ΔH = Hp – Hr
Since the heat of the product is small, the enthalphy change, ΔH will be negative indicating that heat has be released to the surroundings. This is termed exothermic reaction.
Answer:
0 percent chance.
Explanation:
If it is a male then the mom has to be a carrier or have the trait because the dad will pass on a Y, and the trait for colorblindness is linked to the X. If it is a female, she needs 2 of those traits (one from each parent), and since the mom cannot give one, there is not a chance of the kids having colorblindness.
