Which metal absorbs the greatest amount of heat energy
Fed [463]

Answer:

This question is incomplete but the completed question is in the attachment below. And the correct is b

Explanation:

Specific heat capacity can be defined as the amount of heat required to raise to raise 1 kg of a substance by 1 kelvin. Thus, this means that when the specific heat capacity of a substance is high, it takes more energy to increase the temperature of that substance. This also means that when different substances are subjected to the same amount of heat, the substance with the higher specific heat capacity will absorb less heat; for example at a beach, water has a very high specific heat capacity, thus when the sand in the beach is hot, the beach water is still relatively cold.

From the description above, <u>it can be seen that the metal with the least specific capacity will absorb the greatest amount of heat, thus the metal is lead</u> with the specific heat capacity of 0.129 J/(g. °C).

Which of the following correctly describes a compound?
Nutka1998 [239]

A compound is a pure substance formed by the chemical combination of two or more different elements.


A compound may be splitted into simpler substances by chemical reactions, and has different properties to those of the elements that form it.


The composition of a compound is fixed: every piece of a compound has the same kind of atoms, bonded in the same way and proportion.


Some examples of compounds are H₂O, NaCl, H₂O₂, CH₃COOH. As you see, they have a chemical formula which states the kind and number of the atoms that form them.


They are different to mixtures, which are formed by two or more compounds, in a variable proportion, and can be separated by physical media. Some examples of mixtures are the solutions (e.g. NaCl dissolved in H₂O), and some solid mixtures (e.g. a mixture of marbles and sand).

How many miles of O2 can be produced by letting 12.00 miles of KC103 react?
Marat540 [252]
 2KClO3 --> 2KClO2 + O2 
    12                               6    (moles) 
The ratio of KClO3 and O2 is 2:1. This means 2 moles of KClO3 can create 1 mole of O2. So 12 moles of KClO3 will create 6 moles of O2.
