An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

How are primary and secondary pollutants alike?

Zarrin [17]

Answer:

Primary pollutants are emitted from natural or anthropogenic sources directly into the atmosphere, while secondary pollutants result from the chemical reactions or the physical interactions between the primary pollutants themselves or between the primary pollutants and other atmospheric components.

Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other h

aleksandrvk [35]

Answer:

Concentration = 1.32 m

Boiling point = $83.44^{0}C$

Explanation:

Let the boiling point of two solutions = T

Let the molal concentration of the two solutions= m

The relation between elevation in boiling point and molal concentration is:

$elevationinboiling point=K_{b}Xmolality$

i) For benzene

$T-80.1=2.53Xm$

$T=2.53m+80.1$ ....(1)

ii) For carbon tetrachloride

$T-76.8=5.03Xm$

$T=5.03Xm+76.8$ ...(2)

Equating the two equations:

$5.03Xm+76.8=2.53m+80.1\\m=1.32molal$

Putting value of "m" in equation "1"

$T=2.53(1.32)+80.1=83.44^{0}C$

Naoki's bicycle has a mass of 8 kg. If Naoki sits on her bicycle and starts pedaling with a force of 191.4 N, causing an acceler

VladimirAG [237]

58kg

Explanation:

Given parameters:

Mass of bicycle = 8kg

Total force exerted = 191.4N

Acceleration = 2.9m/s²

Unknown:

Naomi's mass = ?

Solution:

Force is a product of mass and acceleration as sated in the second law of newton.

Force = mass x acceleration

Total force on the bicycle = total mass x acceleration

191.4 = (8 + k) 2.9

8 + k = $\frac{191.4 }{2.9}$ = 66

K = 66 - 8 = 58kg
