Classic light bulb running for a full year would use up 876 kWh of energy so yes it does collect energy
H2 is colorless and odorless
NO2 is brown, pungent, and toxic
Supposing all the sulfur in the BaSO4 came from the sample being analyzed:
<span>(1.1756 g)/(233.3909 g/mol) x (1 mol S/ 1 mol BaSO4) x </span><span>(32.0655 g S/mol) / (2.5600 g) = 0.063092
= 6.3092% Sulfur</span>
Answer:
1. Scientific Method, 2. Experiment, 3. Independent variable, 4. Controlled variable, 5. Dependent variable.
Explanation:
Explanation:
The reaction equation will be as follows.
Hence, the expression for is as follows.
Let us assume that the concentration of both and is x.
x = 0.01118034
This means that the concentration of is 0.01118034.
Since, we know that the relation between pH and concentration of hydrogen ions is as follows.
pH =
=
= 1.958
Thus, we can conclude that the pH of a 0.500 M solution of arsenic acid is 1.958.
