A student observes that two objects with identical masses require different amounts of heating to achieve the same temperature change with no phase change. The most likely explanation is

The objects started at different temperatures

Both of the objects have the same specific heat.

The objects are composed of different materials.

One object was heated more quickly than the other.

You have 125g of a certain seasoning and are told that it contains 76.0 g of salt what is the percentage of salt by mass in this seasoning

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
