Answer:
The ratio of the mass ratio of S to O; in SO, to the mass ratio of S to O; in SO₂, is 2:1
Explanation:
According to the consideration, let us first find the ratio of S and O in both the compounds
For SO:
Let us express it as
For SO₂,
Due to two oxygen atoms in the molecule, the mass of oxygen will be taken two times
Let us express it as
Now, for the ratio of both the above-calculated ratios,
The required ratio is 2:1
Answer:
a. because it is an element
Explanation:
its pure because it only has one type of atom, making it an element
Dipyrithione is a chemical with formula, C₁₀H₈N₂O₂S₂. This means that each molecule of the substance has two (2) atoms of nitrogen. By using the dimensional analysis and Avogadro's number, equal to 6.022 x 10²³, we calculate for the answer as shown below.
n = (8.2 x 10²⁴ atoms N)(1 molecule dipyrithione/ 2 atoms of N)(1 mole dipyrithione/ 6.022 x 10²³ molecules dipyrithione)
Simplifying,
n = 6.8 moles dipyrithione
<em>ANSWER: 6.8 moles</em>
Answer:
Heat
Explanation:
Higher temperatures cause solid solutes to dissolve at a faster rate than normal
