Answer:

Increase the particle size of a reactant

Explanation:

Let me rewrite this question. I am assuming that it should be as follows,

If you  _____ the particle size of a reactant then the reaction rate will increase because of the reactant's surface area is exposed allowing more particles to make contact with each other.

And, here we are being asked to fill this dash line _____

It could only be that the particle size increases or decreases. Increasing the size of the reactant will increase the chance of collisions if the container with which the reactants are kept are constant. This would increase the reaction rate - thus _____ = increases.

The Spirit of America Goodyear blimp has a volume of 2.027×105 ft3.When the blimp is in operation, it is filled with helium gas.
Andru [333]
Answer: 1.027 x 10^6 g= 1027kg
In this question, you are given the volume of the blimp (2.027×10^5 ft^3) and the density of the gas(0.179g/L). To answer this question, you need to convert the volume unit into liter. The calculation would be: 2.027×10^5 ft^3 x 28.3168L/ft3= 57.398 x 10^5L= 5.74x10^6L

Then to find the mass, multiply the volume with the density. The calculation would be: 5.74x10^6L x 0.179g/L= 1.027 x 10^6 g= 1027kg
