The joules required to heat 2L of water in a pot from 20 c to the boiling point of water is calculated using the following formula
Q= MC delta T
M = mass = density x volume( 2 x 1000= 2000ml)
M = 1g/ml x2000 ml = 2000g
C = specific heat capacity = 4.18 g/c
delta T = change in temperature = 100 c ( boiling point of water) - 20 c = 80 c
Q is therefore = 2000 g x 4.18 j/g c x 80c = 668800j
Answer:
a correct Lewis diagram for CO2 would look something like this
Explanation:
One C and 2 O. Both O have 4 extra dots and 2 lines/bonds to the C. C has no extra dots.
Hope this helps!
Electrons are the only parts of an atom that can make a chemical bond.
<span>The functional group in organic chemistry is the set of atoms attached to the carbon skeleton that often determine the properties of an organic compound.
Following are major functional groups that are present in an organic compound. carboxylic acid, ester, ether, amine, amide, thiol, halide, alkene, alkyne, phenol, alcohol, aldehyde, ketone, etc.</span>
