what grade is learning What amount of thermal energy (heat) in joules required to raise the temperature of 25 grams of water fro
blsea [12.9K]

Answer:

10425 J are required

Explanation:

assuming that the water is entirely at liquid state at the beginning , the amount required is

Q= m*c*(T final - T initial)

where

m= mass of water = 25 g

T final = final temperature of water = 100°C

T initial= initial temperature of water = 0°C

c= specific heat capacities of water = 1 cal /g°C= 4.186 J/g°C ( we assume that is constant during the entire temperature range)

Q= heat required

therefore

Q= m*c*(T final - T initial)= 25 g * 4.186 J/g°C * (100°C- 0°C) = 10425 J

thus 10425 J are required

Balance the equation. Mg3(PO4)2+? C → ? Mg3P2+? CO , using the smallest possible integers. What is the sum of the coefficients i
Nuetrik [128]

Answer:

Sum of coefficients in balanced equation is 18

Explanation:

Unbalanced equation: Mg_{3}(PO_{4})_{2}+C\rightarrow Mg_{3}P_{2}+CO

Balance O: Mg_{3}(PO_{4})_{2}+C\rightarrow Mg_{3}P_{2}+8CO

Balance C: Mg_{3}(PO_{4})_{2}+8C\rightarrow Mg_{3}P_{2}+8CO

Balanced equation:Mg_{3}(PO_{4})_{2}+8C\rightarrow Mg_{3}P_{2}+8CO

Sum of coefficients in balanced equation = (1+8+1+8) = 18

So, option (4) is correct.
