Answer:
a fruit and oatmeal bar contains 142000 calories.
A nutritional calorie, or kilocalorie, is equal to 1000 calories.
E = 142 kcal · 1000 cal/kcal.
E = 142 000 cal.
Calorie (cal), or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.
One small calorie is approximately 4.2 joules.
A calorie is a unit of energy.
Explanation:
hope it helps :)
Explanation:
when electronegativity difference is from 0.0 to 0.4 then bond formed between the two atoms is non-polar covalent in nature.
When electronegativity difference is greater than 0.4 and less than 1.8 then bond between the two atoms is a polar covalent bond.
When electronegativity difference is 1.8 or greater than the bond formed is ionic in nature.
According to the given fill ups, the reaction equation is as follows.

This means the new products are formed due to the change in chemical composition of the reactants.
- Hence, the equation shows a chemical reaction - the breaking and forming of chemical bonds that leads to a change in the composition of matter.
- And, in the given equation
is a product.
- In the equation,
is reactant.
- In
, the type of bond that holds the two oxygen atoms together is a non-polar covalent bond.
- In
, the type of bond that holds one of the hydrogen atoms to the oxygen atom is a polar covalent bond.
- The number of oxygen atoms on the left side of the equation is equal to the number of oxygen atoms on the right side.
Helium is very difficult to liquify because it only exists in its liquid form at an extremely low temperature. This temperature is <span>low temperature of −269 °C (about 4 K or −452.2 °F). It is only possible to maintain liquid helium in a highly artificial environment where this low temperature can be created. </span>
