Waters high heat capacity is a property focused by hydrogen bonding among water molecules.When heat is absorbed,hydrogen bonds are broken and water molecules can move freely.When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
Answer:
Heat is a measure of the flow of thermal energy from one object or substance to another. ... Thermal energy typically flows from a warmer material to a cooler material. Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases.
Explanation:
Answer:
D. 
Explanation:
Hello!
In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:
Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:
Unlike the other reactions whereas no change in the oxidation states is evidenced.
a core of protons and neutrons surrounds by electrons
The grams of aluminum that are required to produce 3.5 moles of AlO3 in presence of excess O2 is calculated as below
write the equation for reaction
4 Al + 3O2 =2 Al2O3
by use of mole ratio between Al to Al2O3 which is 4 :2 the moles of Al
=3.5 x4/2 = 7 moles
mass of Al = moles / x molar mass
= 7 moles x27 g/mol =189 grams
