A Calorie unit used in food is equal to the amount of energy necessary to raise the temperature of 1 kilogram of water by <u>1</u> degrees Celsius.

<h3>What is One Calorie ?</h3>

The amount of heat energy required to raise the temperature by 1 gram of water through 1°C is known as One Calorie.

1 Calorie = 4.18 J

Thus from the above conclusion we can say that A Calorie unit used in food is equal to the amount of energy necessary to raise the temperature of 1 kilogram of water by <u>1</u> degrees Celsius.

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. What was its acceleration?
Zigmanuir [339]

Acceleration is defined as velocity per unit time.

Acceleration=\frac{Velocity}{time}

a=\frac{dv}{dt}

Here, a=acceleartion,

v=velocity=36 m/s

t=time=12 s

a=\frac{dv}{dt}

a=\frac{36}{12}

a=3 ms⁻²

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².

What is the molar mass of citric acid (c6h8o7) and baking soda (nahco3)?
Rufina [12.5K]

The molar mass of citric acid (c6h8o7) is 192.124g/mol

The molar mass of baking soda (nahco3) is 84.007g/mol

The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample and is measured in moles. Molar mass is a mass property, not a molecular property of a substance.

Molar mass is the mass of 1 mole of the sample. To find the molar mass, add up the atomic masses (atomic weights) of all the atoms in the molecule. Use the masses listed in the periodic table or atomic weight table to determine the atomic mass of each element.
