Explanation:
1) A 45.7 g sample of glass was brought to thermal equilibrium with boiling water and then transferred to 250.0 g of water that was at 22.5 °C. This combination reached thermal equilibrium at 24.2 °C. What is the specific heat capacity of glass?
2) What mass of silver at 100.0 °C, when added to 150.0 g of water at 21.0 °C, would raise the water’s temperature to 24.0 °C ?
3) The molar heat of fusion of H2O is 6.1 kJ/mole. What amount of energy would be needed to melt 376 g of ice at 0.0 °C?
Answer:
C. Electrons equal the number of protons
Explanation:
An atom is electrically neutral because...
a. Neutrons equal the number of protons
b. Proton forces pull on the neutrons
C. Electrons equal the number of protons
d. Electrons equal the number of neutrons
to be electrically neutral, the number os positive charges from thethe negative charges from the electrons
so
the number of protons must equal the number of electrons
ignore neutrons, they have NO charge
so
C. Electrons equal the number of protons
