Answer:
8.0 g
Explanation:
To convert moles to grams, you need to use the molar mass. The molar mass of sulfur is 32.06. The molar mass is the atomic mass of the atom.
(0.25 mol) × (32.06 g/mol) = 8.015 g
Round for significant figures.
8.015 g ≈ 8.0 g
Silver (Ag) is a metal, and is thus the most likely to be malleable. NaCl (sodium chloride, or salt) is brittle and a typical ionic compound in terms of its properties. Nitrogen and propane are generally gases or liquids.
Explanation:
An apple pie is a mixture whereas lead iodide is a compound. To processes leading to the formation of a mixture and a compound are completely different.
- A compound is a substance composed of two or more kinds of atoms that are joined together to form a definite matter.
- The properties of the compound formed differs from that of the constituent atoms.
- A mixture on the other hand is made up of indefinite compositions.
- In the case of the apple pie, the parts are not homogeneous in nature.
To produce lead iodide, chemical reactions must take place between atoms.
In the case of the pie, chemical and physical changes can take place.

Answer:
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This law is taught in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes. When playing pool, the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.

Answer:
Number of moles = 0.116 mol
Explanation:
Given data:
Number of moles of potassium bromide = ?
Volume of solution = 68.5 mL
Molarity of solution = 1.65 M
Solution:
First of all we will convert the mL into L.
68.5 mL × 1 L /1000 mL
0.07 L
Molarity = Number of moles / Volume in litter
we will rearrange the formula:
Number of moles = molarity × volume in litter
Now we will put the values in formula:
Number of moles = 1.65 M ×0.07 L
Number of moles = 0.116 mol
