B. a flashlight a basketball and a softball. the flash light would give off the light from the sun and the softball will block out some of the light in front of a basketball
Molar mass KI = 166.0028 g/mol and Pbl₂ = 461.0089 g/mol
2 Kl + Pb(NO₃)₂ ------> 2 KNO₃ + Pbl₂
2 x 166.0028 g ---------> 461.0089 g
? g KI -------------> 1.2 g
Mass KI = 1.2 x 2 x 166.0028 / 461.0089
Mass KI = 398.40672 / 461.0089
<span>Mass KI = </span>0.86 g
Answer B
<span>hope this helps!</span>
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
Say that you have 100³
instead of writing and solving 100x100x100 three times to solve it, you can just write 100³
the exponents in scientific notation make the whole process easier.
Answer:
In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant.
