3.) likely to form an ionic bond
Metals and non-metals combine to form ionic bonds.
I think the correct answer would be the third option. From the physical change that happened, we can only tell that the mass of the plastic would be still the same and would weigh 15 grams. This is in accordance with the Law of conservation of mass where it states that mass cannot be destroyed or created. So, since it is only a physical change that happens the substance itself would still be the same and it is only the form that is changed, it would still have the same mass. However, with the change, the volume is changed and is said to increase which means it would greatly affect the density. Increasing the volume would result to a decrease in density.
Based on their percent concentration, the 5% sugar solution contains more water.
<h3>What is the concertation of a solution?</h3>
The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.
Concentration of solutions can be expressed as either:
- molar concentration
- mass concentration
- percentage concentration
The concentration of the sugar solutions are given as percent concentration.
The 5% sugar solution contains 5% sugar and 95% water
The 10% sugar solution contains 10% sugar and 90% water.
Therefore, the 5% sugar solution contains more water.

Answer:
84.27 g
Explanation:
<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>
Step 1: Calculate the moles of atoms of hydrogen
The molar ratio of C₃H₈ to H is 1:8.
10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H
Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen
The molar mass of hydrogen is 1.008 g/mol.
83.60 mol × 1.008 g/mol = 84.27 g
