PLEASE HELP I AM FAILING SCIENCE!!!

Chemistry
1 answer:
kherson [118]3 years ago
8 0

Answer: B. Mg

Explanation:

Ionization energy is the energy required for the removal of valence electron from an isolated gaseous atom.

Ionization energy increases as we move across the period as the atomic size decreases as the electrons are being added to the same energy level.

Ionization energy decreases as we move down the group as the atomic size increases due to the addition of shells.

As magnesium (Mg) lies to the right of Sodium (Na) and Poatssium (K) and Calcium (Ca) lies below Magnesium (Mg), Mg has the highest ionization energy.

A given atom has 3 protons, 4 neutrons, and 3 electrons. Describe how you can use those three values to describe the structure,
ELEN [110]
Charge # = protons - electons 

Mass # = protons + neutrons 

so that would be 

3-3= charge#
3+4= mass#

A burner on a stove produces temperature. thermal energy. hotness. fire energy.
Aleksandr [31]

Question:

The options are;

a. Temperature

b. Thermal Energy

c. Hotness

d. Fire Energy

Answer:

The correct option is;

b. Thermal energy

Explanation:

A burner on a stove produces thermal energy which is used to raise the temperature of the metal container (kettle, pot or pans) in which items are placed for heating.

Thermal energy is the internal energy of the system given off as heat which when transferred from one body to another causes the temperature of the receiving body to rise. Thermal energy in a burner is given off when the gaseous fuel reacts or burns in the presence of or with oxygen to produce carbon dioxide and water vapor in an exothermic reaction.

4C + 5H₂ + 13/2O₂ (-125 kJ) → C₄H₁₀ + O₂ → CO₂ + H₂O (-2877 kJ).
