Chemistry
1 answer:
Alexandra [31]2 years ago

Answer:

Single displacement and reduction

Explanation:

In a single-displacement reaction, one element exchanges partners with another.

\rm Ca + 2H$_2$O $\longrightarrow$ Ca(OH)$_2$ + H$_2$

This is a single-displacement reaction, because the element Ca exchanges partners with H.

This is also a reduction/oxidation (redox) reaction, because the optically active of Ca increases from 0 to +2 (oxidation), while the oxidation number of H decreases from +1 to 0 (reduction),

The most common types of reactions are:

  • Combination
  • Decomposition
  • Single displacement
  • Double displacement
  • Reduction/oxidation

The atomic mass is the sum of the number of ________ and ________ in the nucleus of an atom. Choose two answers from the options
iVinArrow [24]

Answer :

The atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom.

Explanation :

Atomic number : it is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number or atomic mass : It is defined as the sum of the number of protons and the number of neutrons.

Mass number or atomic mass = Number of protons + Number of neutrons

For example :

Number of protons in carbon = 6

Number of neutrons in carbon = 6

Mass number or atomic mass = Number of protons + Number of neutrons

Mass number or atomic mass = 6 + 6

Mass number or atomic mass = 12

Thus, the atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom.

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.
