When a substance is soluble in water, the smallest pieces of the substance spread out in the water as individual atoms or molecules.

How does being dissolved in water affect two substances that are chemically reacting with one another?
A.
It helps the chemical reaction occur more easily.
B.
It makes the chemical reaction occur slower.
C.
It causes the substances to react with the water.

What happens when the temperature of a solution increases?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

What are the advantages of using the metric system? designed as a decimal system making conversions simpler more accurate system of measurement has prefixes that correspond to an amount to use with all base units used by the entire scientific community
