Answer:
Option B. HgCl2
Explanation:
Data obtained from the question include:
Mass of Mercury (Hg) = 47.3g
Mass of chlorine (Cl) = 16.7g
The empirical formula for the compound can be achieved by doing the following:
Step 1:
Divide by their individual molar mass
Hg = 47.3/201 = 0.235
Cl = 16.7/35.5 = 0.470
Step 2:
Divide by the smallest to express in whole number:
Hg = 0.235/0.235 = 1
Cl = 0.470/0.235 = 2
Therefore, the empirical formula is HgCl2
Answer:
1 is b and 2 is d
Explanation:
because you do not know that the cat had done that you was just thinking it was the cat
You are given
130 grams of H20 and 18 grams of H2. You are required to get the theoretical
yield of H2O. Before anything else, you should know the chemical equation of
H20 and H2. The balanced chemical reaction is 2H2 + O2 -> 2H2O. The molar
mass of H2O is 18 grams per mole and the 2 grams per mole for H2.
18g H2 (1 mol
H2/2 g H2)(2 mol H2O/ 2 mol H2)(18 g H2O/1 mol H2O) = 162 g H2O
<span>Thus the <u>theoretical
yield for 18g H2 is 162g H2O.</u></span>

Answer:
263 K
Explanation:
Assuming ideal behaviour and constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:
In this case:
We <u>input the data</u>:
- T₁ * 824.7 mL = 377 K * 575.45 mL
And <u>solve for T₁</u>:
