Louis pasteur performed a series of experiments that disproved spontaneous generation. what aspect of his design represented the experimental part of the test

Two different kinds of flasks were used - regular and swan-necked

Explanation:

In his experimental design, Louis Pasteur used tow flasks. One of the flask was regular flask and the other was swan necked. He used these flasks to boil a meat broth. In the swan neck flask, air could enter but microorganisms could not. As a result, there was no grown seen in that flask. In the regular flask, microorganisms could enter and they spoiled the meat. Hence, the two different types of flasks were his experimental design.

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.
