Answer:

The answer is of course, D

Explanation:

For example, since potassium (K) is a metal and chlorine (Cl) is a nonmetal, if these two elements combine, they will form an ionic bond. If carbon (C), a nonmetal, and oxygen (O), a nonmetal, combine, they will form a covalent bond.

The answer is option D

(although in reality both ionic and covalent bonds are the same thing. the degree of how polar the molecule is determines it's nature)

Differentiate between strong and weak acid

Free_Kalibri [48]

Answer:

Acid solutions contain hydrogen ions. The higher the concentration of hydrogen ions, the lower the pH. Strong acids are fully ionised but weak acids are only partly ionised in solution.

Example:

Hydrochloric acid is a strong acid and ethanoic acid is a weak acid.

A gas mixture consists of 60.0% Ar, 30.0% Ne, and 10.0% Kr by volume. If the pressure of this gas mixture is 80.0 kPa, what is t

Nat2105 [25]

Answer: The partial pressure of Argon , Neon and krypton are 48 kPa , 24 kPa and 8 kPa respectively.

Explanation:

According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

$p_A=x_A\times P_{total}$

where, $p_A$ = partial pressure of component A

$x_A$ = mole fraction of A

$P_{total}$ = total pressure

mole fraction of Ar = $\frac{\text {Moles of Ar}}{\text {total moles}}=\frac{60.0}{60.0+30.0+10.0}=0.6$

$p_{Ar}=0.60\times 80.0kPa=48kPa$

mole fraction of Ne = $\frac{\text {Moles of Ne}}{\text {total moles}}=\frac{30.0}{60.0+30.0+10.0}=0.30$

$p_{Ne}=0.30\times 80.0kPa=24kPa$

mole fraction of Kr = $\frac{\text {Moles of Kr}}{\text {total moles}}=\frac{10.0}{60.0+30.0+10.0}=0.10$

$p_{Kr}=0.10\times 80.0kPa=8kPa$

What is a chemial property og hydragion peroxide

AlladinOne [14]

Answer:

Hydrogen peroxide is a colorless liquid at room temperature with a bitter taste. Small amounts of gaseous hydrogen peroxide occur naturally in the air. Hydrogen peroxide is unstable, decomposing readily to oxygen and water with release of heat.

DUE TONIGHT!

GuDViN [60]

Answer:

27J/Kmol

Explanation:

Heat = number of moles times the Moeller heat capacity chimes the change in temperature.

^ Q = nC△T

^ C = Q/ n△T = +53J / (1mol) (299.5K - 297.5K)

^ = 26.5 (rounded to 27)
