How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams from 0.0 to 100.0

Q = 19255.6 j

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Given data:

Mass of water = 46 g

change in temperature = ΔT = 100-0.0 = 100 °C

Heat absorbed by water = ?

Solution:

Specific heat capacity of water = 4.186 j/g. °C

Q = m.c. ΔT

Q = 46 g×4.186 j/g. °C×100 °C

Q = 19255.6 j

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
