The atomic number of argon is 18. will argon tend to form bonds with other elements? explain your answer.
koban [17]
Argon atoms would not tend to make bonds with other atoms since it is classified as a noble atom which means it has a complete filled subshells. It does not have any electrons that are available for bonding. Noble gases belong to the Group 8A in the periodic table of elements. All of the elements in this group do have a complete or filled electron orbitals which makes them so stable or the s and p outer electron shells are complete with electrons. All of them follows the octet rule. Thus, they do not need any sharing or transfer of electrons from other compounds for them to be more stable.

A sample of lemon juice has a pH of 3. What is the [OH-] concentration of the lemon juice? A) 11 B) 1 X 10+3 C) 1 X 10-3 D) 1 X
Likurg_2 [28]

pH scale is used to determine the acidity of a solution

pH is calculated using the H⁺ concentration

pOH scale is used to determine how basic a solution is

pOH is calculated using the OH⁻ concentration

pH and pOH are related in the following formula

pH + pOH = 14

pH = 3

pOH = 14 - 3

pOH = 11

pOH is calculated using the following formula

pOH = - log[OH⁻]

[OH⁻] = antilog(-pOH)

[OH⁻] = antilog(-11)

[OH⁻] = 1 x 10⁻¹¹ M

the [OH⁻] concentration of lemon juince is D) 1 x 10⁻¹¹ M

Monosodium glutamate (NaC5H8NO4) is used extensively as a flavor enhancer what is its percent composition
tensa zangetsu [6.8K]

Answer:

% sodium= 13.6 % sodium

% carbon= 35.5 % carbon

% hydrogen= 4.7% hydrogen

% nitrogen = 8.3% nitrogen

% oxygen = 37.8 % oxygen

Explanation:

To find its percent composition means that we are to find to find the percentage of each of the constituents of the compound present.

The molar mass of monosodium glutamate is 169.11 gmol-1

Hence;

Percent of sodium= 23 gmol-1/169.11 gmol-1 × 100 = 13.6 % sodium

Percent of Carbon= 60 gmol-1/169.11 gmol-1 ×100 = 35.5 % carbon

Percent of hydrogen= 8/169.11 gmol-1 ×100 = 4.7% hydrogen

Percent nitrogen = 14/169.11 gmol-1 × 100 = 8.3% nitrogen

Percent oxygen = 64/169.11 gmol-1 ×100 = 37.8 % oxygen
