A 55.0 grams sample of strontium arsenite is mixed with 65.0 grams of chromic acid in a double replacement reaction form strontium chromate and arsenous
acid. After the reaction was performed, 45.7 g of the actual strontium chromate
were collected.
a. Determine the limiting reactant.
b. Determine the excess reactant.
c. Determine the theoretical yield of Strontium Chromate in grams.
d. Determine the amount of excess reactant left over in grams
e. Determine the percent yield of strontium chromate.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
