What are three ways the rate of a chemical reaction can be changed

The temperature - warmer debris circulate swifter and collide greater oftentimes with greater ability.

2. The rigidity - debris in gases squeezed at the same time will collide greater oftentimes.

3. concentration of any reactants in answer.

4. floor section of any good reactants (powders have a larger entire floor section)

5. The presence of a catalyst. (catalysts decrease the activation ability)

Explanation:

it would lead to upper respiratory infections and pneumonia.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
