Answer:

Explanation:Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical ... Chemical formula. CaO ... Both it and a chemical derivative (calcium hydroxide, of which quicklime is the base anhydride) are important commodity ... The major use of quicklime is in the basic oxygen steelmaking (BOS) process.

Answer:

Anion

Explanation:

Anion is an atom or group of atoms that are negatively charged.

Cations are positively charged

Anode is a positively charged pole that conducts electricity (remember electrolysis)

A certain gas is present in a 10.0 LL cylinder at 4.0 atmatm pressure. If the pressure is increased to 8.0 atmatm the volume of
ICE Princess25 [194]

Answer:

The gas obeys Boyle’s law and the value of k_i\&k_f both are equal to 40.0 atm L.

Explanation:

Initial volume of the gas = V_1=10.0 L

Initial pressure of the gas = P_1=4.0 atm

Final volume of the gas = V_2=5.0 L

Final pressure of the gas = P_2=8.0 atm

This law states that pressure is inversely proportional to the volume of the gas at constant temperature.  

PV=k

The equation given by this law is:

P_1V_1=P_2V_2

P_1\propto \frac{1}{V_1}

P_1V_1=k_i

k_i=4.0 atm\times 10.0 L = 40.0 atm L

P_2\propto \frac{1}{V_2}

P_V_2=k_f

k_f=8.0 atm\times 5.0 L = 40.0 atm L

k_i=k_f=40.0 atm L

The gas in the cylinder is obeying Boyle's law.

The gas obeys Boyle’s law and the value of k_i\&k_f both are equal to 40.0 atm L.

Why are valence electrons important
koban [17]

Explanation:

The electrons in the outermost shell of an atom are the valence electrons. These electrons are the most loosely held in an atom.

The energy required to remove these electrons are not as great as those of the inner shell electrons.

  • Atoms of some elements show no tendency to combine with other  atoms because they have completely filled outer energy levels.
  • Their outermost shell, valence shell and the electron numbers are complete for them. These are the noble gases.
  • other atoms share or exchange their valence electrons in order to have a stable configuration.
  • The valence electrons are involve in inter-atomic bond formation and interactions
  • Also the distribution of these electrons determines inter-molecular interactions between molecules.
