How much energy is required to heat 14 grams of water from 18 degrees Celsius to 47 degrees Celsius

Explanation:

Hello!

In this case, since the calculation of the required energy is performed via the following equation:

Thus, since the mass is 14 g, specific heat is 4.184 J(g*°C) and the temperatures are 47 °C and 18 °C respectively, the resulting energy is:

Best regards!

i think   the answer is c hope i'm right

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
