Answer : According to the definition of law of refelection "<em>It is </em><span><em>the principle in which, when a ray of light or radar or pulse, is shined on a smooth surface it is reflected back from the smooth surface and the angle of reflection will be equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface at the point of incidence all will lie in the same plane."

</em>So we can define angle of incidence as - The angle which is formed between the incident ray and the smooth surface of substrate is called angle of incidence and the incident ray will be always intersecting at the point of normal with the reflected ray. So the normal is an imaginary line which is perpendicular to the smooth surface of the substrate which bisects the ray of incidence and forms the angle of incidence also it bisects the ray of reflection and forms angle of reflection.</span>

What do you use to determine molar mass?
levacccp [35]

Answer:

the molar mass of any element can be determined by finding the atomic mass of the element on the periodic table for example, if the atomic mass of sulfer is 32.066 amu, then it's molar mass is 32.066 g / mol

Match the following aqueous solutions with the appropriate letter.
Alla [95]

Answer:

Explanation:

When a salt is dissolved , it increases  the boiling point . Increase in boiling point depends upon number of ions . So it is a colligative property .

.19 m AgNO₃ . Each molecule  will ionize into two ions . So effective molar concentration is 0.19 x 2 = .38 m

0.17 m CrSO4.Each molecule  will ionize into two ions . So effective molar concentration is 0.17 x 2 = .34 m

0.13 m Mn(NO₃)₂. Each molecule  will ionize into three  ions . So effective molar concentration is 0.13 x 3 = .39 m

0.31 m Sucrose(nonelectrolyte). Molecules will not ionize . So effective molar concentration is 0.31 x 1 = .31 m

Higher the molar concentration , greater the depression in boiling point .

So lowest boiling point is 0.13 m Mn(NO₃)₂.

second highest  boiling point is 0.19 m AgNO3.

Third lowest boiling point is 0.17 m CrSO4

Highest boiling point or lowest depression 0.31 m Sucrose.

a . 4

b .  1

c . 2

d . 3

A chemist determined by measurements that 0.030 moles of barium participated in a chemical reaction. Calculate the mass of bariu
schepotkina [342]

Answer: 4.1 g of barium precipitated.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}

Given : moles of barium = 0.030

Molar mass of barium = 137 g/mol

0.030=\frac{x}{137}

x= 4.1 g

Thus there are 4.1 g of barium that precipitated.
