First part is polar, second part is non-polar. Use the saying "like dissolves like". Substances that are alike in polarity are more likely to dissolve one another.

Answer : Polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.

Explanation :

According to the concept of “Like dissolves like”, the polar solvents dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.

For example : In the ionic compounds, like sodium chloride are soluble in the water. And as we know that the water molecules are polar in nature. So, they interact with the sodium and chloride ions.

Hence, the polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()zn

Bingel [31]

Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.

Given chemical reaction is:

Zn + HCl → ZnCl₂ + H₂

Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:

Zn + 2HCl → ZnCl₂ + H₂

Hence we add 2 as a coefficient of HCl to balance the equation.

ELEN [110]

Answer:

3 × 10¯¹⁰

Explanation:

9×10² ÷ 3×10¹²

The above expression can be evaluated as follow:

9×10² ÷ 3×10¹²

Recall:

3² = 9

3¹ = 3

Therefore,

9×10² ÷ 3×10¹² = 3²×10² ÷ 3¹×10¹²

Recall:

y^m ÷ y^n = y^(m – n)

Therefore,

3²×10² ÷ 3×10¹² = 3²¯¹ × 10²¯¹²

= 3¹ × 10¯¹⁰

Recall:

y¹ = y

Therefore,

3¹ × 10¯¹⁰ = 3 × 10¯¹⁰

Therefore,

9×10² ÷ 3×10¹² = 3 × 10¯¹⁰

Why krypton and noble gas are not used in airships using the periodic table?

WITCHER [35]

Answer:

Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.
