shepuryov [24]

Answer:

Physical

Explanation:

The change of density alone is a physical change, but there might be some chemical change that results in physical change. For example: Burning a piece of paper will definitely change the density of the paper as some of its content is being changed into smoke which is a gas. So there will be a change in volume which in turn leads to change in density. Therefore, the change of density alone is a physical change, but the change might occur due to another chemical change.

Metallic aluminum reacts with MnO2 at elevated temperatures to form manganese metal and aluminum oxide. A mixture of the two rea
Oksi-84 [34.3K]

Answer:

Explanation:

To find the theoretical yield of the equation. First identify the limiting reactant in a chemical equation.

Step 1: write out the equation and balance it.

Al+ 3mno2=3mn+ 2Alo3.

The limiting reactant is mn02 because it is not found in excess.

Step 2: convert the % to gram . All contain 67.2% mole and mno2 will be 100-67.2= 32.8

All=67.2÷100×290(total gram of the reactants)=194.88g

Mno2=32.8÷100×290g=94.12g.

Step 3:calculate the molar mass of mno2 and that of mn. The atomic mass of mn is 54.9380 and that of oxygen is 16.

Mno2=54.938+ (16)2=86.98g/mol.

Mn=54.938.

Step 4:

From your balanced equation , calculate mn.

94.12g mno2× (1mol mno2÷86.98(molarmass) of mno2×3 mol of mn/4molAl×54.938g of mn÷1mol of mn.

94.12g×1÷86.98g×3÷4×54.938÷1

=44.58g

Fission creates large amounts of: A.uranium B.air pollution C.carbon dioxide D.radioactive waste
Vaselesa [24]

Answer: -

Fission creates large amounts of radioactive waste.

Explanation: -

During nuclear fission, by products are formed. These by products are radioactive in nature. They give radiation. These radiation causes a lot of harm to humans including cancer and mutations.

Thus, Fission creates large amounts of radioactive waste.
