Explanation:
Answer:
We will produce 8.0 moles of HCl , this is 291.7 grams HCl
Explanation:
Step 1: Data given
Number moles of H2S = 3.0 moles
Step 2: The balanced equation
2HSbCl4 + 3H2S → Sb2S3 + 8HCl
Step 3: Calculate moles HCl
For 2 moles HSbCl4 we need 3 moles H2S to produce 1mol Sb2S3 and 8 moles HCl
For 3.0 moles H2S we'll have 8.0 moles HCl
Step 4: Calculate mass HCl
Mass HCl = moles HCl * molar mass HCl
Mass HCl = 8.0 moles * 36.46 g/mol
Mass HCl = 291.7 grams
We will produce 8.0 moles of HCl , this is 291.7 grams HCl
Answer:
The phosphorus minerals deposits that are available right now are not enough for the future. A large part of food production depends on phosphorus being produced. Phosphorus is commonly used as fertilizer and a lot of farmers are dependent on it.
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Answer:
[OH⁻] = 3.55×10⁻¹⁰M
Explanation:
Given data:
pOH of vinegar = 9.45
[OH] = ?
Solution:
Formula:
pOH = -log[OH⁻]
Now we will put the value of pOH.
9.45 = -log[OH⁻]
[OH⁻] = 10∧-pOH
[OH⁻] = 10⁻⁹°⁴⁵
[OH⁻] = 3.55×10⁻¹⁰M
