_____________________________

A chemical reaction in which heat is released is called exothermic reaction.

For example

CaO(s) + H2O(l) --> Ca(OH)2 (aq) + Heat

As we know that if energy needed in the bond breaking in the reactants is less than the energy released when new bonds are formed resulting in the products, the chemical reaction is of exothermic in nature.

Bob adds heat to a substance. When enough heat is added, A. its particles move closer together and the substance becomes a gas.
Elena L [17]

Answer:

C. its particles move farther apart and the substance becomes a gas.

Explanation:

A. is wrong because moving closer together creates a solid, not a gas.

B. is wrong because moving father apart creates a gas, not solid.

C. is correct because moving farther apart creates a gas.

D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.

- Just know the states of matter and how the particles move and that will help with this problem.

What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons? what is the symbol for an ion that has 16 pro-tons,
Goshia [24]

When we go to periodic table, Sulfur is an element that has 16 protons and 16 electrons.

when there is 18 electrons, with number of two electrons more than protons. This makes it an ion and the ion has a -2 charge.

So when there is16 protons, 18 neutrons, and 18 electrons the symbol is S⁻².

The neutrons have no charge but they add only mass to the elements. So when there is 16 neutrons, it doesn't change the symbol of ion.
