Explanation:
the further down the group you go, the larger the radius becomes. its caused by the amount of electrons needed to equal out the charge of the nucleus
a.
A substance's specific heat tells you how much heat is required to increase the temperature of 1 g of that substance by 1°C.
The equation that establishes a relationshop between heat and change in temperature is
q = m • c • ∆T, where
q - heat absorbed
c - the specific heat of the substance, in your case of water
ΔT - the change in temperature, defined as the difference between the final temperature and the initial temperature
so:
q = 1.00 g • 4.18 J/g×°C • (75.0 - 38.5)°C
q = 152,57 J
just apply this formula for all exercises
Frosty the snowman is GUILTY. he broke into a room that was 20 degrees F, then moved into the room with the safe, which was 65 degrees F, above the freezing point, and no snow can not melt at 65 degrees. as he was tromping through the hot house, he began to turn back into liquid because he began melting in the heat. so all evidence points towards the fact that frosty did it.
The answer should be 12 since 4 x 3 = 12
This is because ammonia is NH^3 and if it has a number before it you multiply it with the rest of the chemical equation.
I hope this helps
I think its the mirror because condenser helps in allowing the amount of light to pass.
