How much heat does it take to raise the temperature of 7.0 kg of water from 25°C to 46°C? The specific heat of water is 4.18 kJ/(kg•°C).
Use Q = md Tr-T).
O A. 148 kJ
B. 176 kJ
0 C. 610 kg
D. 320 kJ

where's the diagram?

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

the ratio of the conjugate base to the acid required to attain the desired ph.
