If a 150 gram iron bar is heated to 250c a second iron bar with a mass or 300 grams is heated to 250c which bar has the most thermal energy?

i would say that the 150 gram bar because the thermal energy will be able to travel around the bar quicker

Does it take more thermal energy to raise the temp of 6 grams of water by 8 degrees C or 5 grams of ice by twenty degrees C?
Ice. For 6 gr of water and 8 deg C you need 6 x 8 = 48 calories For 5 gr of ice and 20 deg C you need at least 100 ( 5 x 20) if we neglect small difference in the specific heat of ice versus water. If the ice melts then you need additional thermal energy to break the hydrogen bonds in ice (melting thermal energy) so it is even more.
What is the percent yield of the decomposition reaction if 9.9 grams Pb(NO3) are heated to give an actual yield of 5.5 grams of PbO?
The yield is 82,45 %.
If you were to have 80 grams of uranium how many grams would be present at the end of the second half time?
After the second half-life of uranium, half of the original amount will remain. Therefore, if you start with 80 grams of uranium, after one half-life you would have 40 grams remaining, and after the second half-life, you would have 20 grams.
When heated mercury oxide produces oxygen plus mercury what would be the combined mass of oxygen and mercury if 20g of mercury oxide were heated?
If 20g of mercury oxide were heated, the combined mass of oxygen and mercury would be 20 grams.
How do I covert calories into grams?
You can't. Calories are a unit of energy and grams are units of mass.
How is it possible that something can have a high temperature but very little thermal energy?
Thermal energy is a product of two variables; the temperature, and the mass. If two objects having the same mass were heated to the same temperature, they would have the same thermal energy. If an object weighing ten grams was heated to 1000º C, it would have less thermal energy than an object weighing 2 tons, heated to 100º C. To demonstrate this, imagine the amounts of ice each of the above objects could melt.
What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?
(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.

Why the 100 grams of ice would have a greater volume 100 grams of water?
When the water froze into ice it was expanding (thermal expanision) causing the 100 grams of ice to have a greater volume than 100 grams of water!

When heated mercury oxide produces oxygen plus mercury what would be the combined mass of oxygen and mercury if 20g of mercury oxide were heated?
If 20g of mercury oxide were heated, the combined mass of oxygen and mercury would be 20 grams.
What has more kinetic energy a mass of 200 grams or a mass of 2000 grams or a mass of 20000 grams?
Assuming all have equal velocity the greater mass (20000g) will have the greater kinetic energy.
What is the total mass of products formed when two point five grams of Barium Carbonate completely decomposes when it is heated?
Also 2.5 grams - law of conservation of matter.
5 grams of salt is dissolved in 100ml of water. the solution is heated and the water is boiled away. How much salt is left?
Five grams of salt remain theoretically.
