Answer:
C. matter
Explanation:
When hydrogen atoms collide at very high speeds, the natural electrostatic repulsion that exists between the positive charges of their nuclei is overcome and the atoms fuse, this fusion of light hydrogen atoms produces a heavier element, helium.
<em>In short, nuclear fusion is a process by which nuclear reactions between light elements form heavier elements (up to iron), therefore fusion produces new types of matter. </em>

Answer:
D. 91.0%
Explanation:
Hello,
In this case, for the given chemical reaction:
Next, since silver nitrate (molar mass 169.87 g/mol) is in a 2:1 molar ratio with silver sulfide (molar mass 247.8 g/mol), we compute its theoretical yield as shown below:
Next, we compute the percent yield as:
Hence, answer is D. 91.0%.
Best regards.
<span>This is false. A carbohydrate is a carbon-based molecule that can be utilized by living organisms in order to produce energy. A calorie is a unit of energy often used to measure the amount of energy within food. Another example of energy unit is the Joule, more commonly used within physics.</span>

Answer:
9 moles of ions
Explanation:
Our compound is: CaCl₂(s)
We dissociate it:
CaCl₂(aq) → Ca²⁺ (aq) + 2Cl⁻(aq)
Per 1 mol of chloride, we have 1 mol of calcium cation and 2moles of chlorides, so in total we have 3 moles of ions.
Therefore in 3 moles of chloride, we would have 9 moles of ions (3 . 3)
