Answer:

arrangement of outermost electrons

Explanation:

Chemical bonding typically involves only the outermost electrons of the atom, while the inner electrons and nucleus remain the same. Some arrangements of outermost electrons are much more stable than others.

When an atom forms chemical bonds, its arrangement of outermost electrons becomes more stable. An atom is form by a nucleus, made by protons and neutrons, and by a different number of rings that contains electrones. The outermost ring is the one that bonds with other atoms to form chemical bonds, so it is the one that could become more stable.

Describe how to use the periodic table to identify characteristics of elements/atoms.

timofeeve [1]

Answer: The simplest way to use the periodic table to identify an element is by looking for the element's name or elemental symbol. The periodic table can be used to identify an element by looking for the element's atomic number. The atomic number of an element is the number of protons found within the atoms of that element.

In the reaction Ca + Cl2 → CaCl2, what is the mole ratio of chlorine to calcium chloride?

Anit [1.1K]

Answer:

D. 1:1

Explanation:

For every 1 mole of chlorine (Cl₂), there is one mole of calcium chloride (CaCl₂).

So, the mole ratio of chlorine to calcium chloride is 1:1.

Hope this helps. :)

The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium h

7nadin3 [17]

Answer:

0.022 M

Explanation:

The molarity is the number of mol solute divided by the volume of solution in liters. Since we are told there is only one acidic hydrogen in KHP the reaction is a 1 to 1 with sodium hydroxide, We then calculate the moles of sodium hydroxide required to react with the moles of KHP and proceed to calculate the molarity of the NaOH solution:

mol KHP: 0.1082 g x 1 mol/204.22 g = 0.00053 mol KHP

0.00053 mol KHP x 1 mol Naoh/1 mol KHP = 0.00053 mol NaOH

Molarity of the solution : 0.00053 mol NaOH / 0.02346 L = 0.022 M

note: The volume of sodium hydroxide needed to be converted to liters by definition of molarity.
