Determine the number of atoms in 0.075 mol of Carbon (C)? please help
nignag [31]
It would be C, 6.2 x 10^23.

Avogadro's number, or, the mole, is 6.02 x 10^23. Although the grams and molar mass of an element may be different, every element must have the same amount of atoms to obey avogadro's number.

When food spoils, it is a chemical reaction. For example, rancid butter is produced when the fat molecules in the butter undergo
Sergio039 [100]

Answer: Decreases the rate of reaction

  • Remove water from food by dehydration.
  • Transport food in a refrigerated truck.
  • Store food in airtight containers.
  • Store food in a refrigerator after opening.

Does not decrease the rate of reaction

  • Store food in the open air.
  • Place food on a warm surface.

Explanation: Dehydration of food excludes water from food which is one of the factor needed by microorganisms for growth, <em>so it decreaese the rate of reaction.</em>

Transporting food in refrigerated trucks lowers the temperature of food and not many microorganisms are active at very low temperatures, so it <em>decreases the rate of reaction.</em>

Storing food in airtight containers excludes air which is one of the factors required for microbial activity, so <em>it decreases reaction rate.</em>

Storing food in refrigerators after opening also <em>lowers the temperature of food and hence the the rate of microbial activit</em>y.

Storing food in the open air <em>does not decrease microbial activity</em> instead it provides microorganisms with the favorable conditions for their activity such as air and water from water vapor in the air.

Placing food on a warm surface <em>does not decrease rate of reaction</em> because microorganisms are very active in warm and humid environments.
