Angle of incidence and refraction for air at 0 degrees?

Chemistry
1 answer:
iVinArrow [24]2 years ago
4 0

Answer:

zero

Explanation:

When the air is zero degrees then it implies that the air is travelling at an perpendicular to the normal direction.  

Therefore, the angle of incidence would be zero degree and in relation to that the angle of reflection and refraction would also be zero degree as per the laws of reflection.  

In other ways it can be said that the light goes un-deviated.

A solid piece of lead has a mass of 23.94g and a volume of 2.10cm^3. from these data, calculate the density of lead in si units
jeyben [28]
A density of a substance is constant. It is an extensive property, meaning it does not depend on the amount of substance because it is a ratio of mass to volume. No matter how much of each there is, they would always have a fixed ratio called density. For lead, the density is

Density = mass/volume
Density = 23.94 g/ 2.10 cm³
Density = 11.4 g/cm³

The density of water at 4 degrees Celsius is 1.000 g/mg is it chemical or physical property?
Kaylis [27]

Answer:

Physical Property

Explanation:

Density, mass, volume, color, melting and boiling points, etc. are all physical properties. No matter what changes, the chemical makeup stays the same.

Flamability, acidity, toxicity, etc. are chemical properties, because they chemically change the makeup of the object/thing.

13.50 grams of Pb(NO3)4 are dissolved in enough water to make 250 mL of solution. What is the molar its of the resulting solutio
likoan [24]
Data:
M (molarity) = ? (M or Mol/L)
m (mass) = 13.50 g
V (volume) = 250 mL → 0.25 L
MM (Molar Mass) of Lead(IV) Nitrate Pb(NO_3)_4
Pb = 1*207 = 207 amu
N = (1*14)*4 = 14*4 = 56 amu
O = (3*16)*4 = 48*4 = 192 amu
------------------------------------
MM of Pb(NO_3)_4 = 207+56+192 = 455 g/mol

Formula:
M =  \frac{m}{MM*V}

Solving:
M = \frac{m}{MM*V}
M =  \frac{13.50}{455*0.25}
M =  \frac{13.50}{113.75}
M = 0.118681318...\:\:\to\:\:\boxed{\boxed{M \approx 0.119\:Mol/L}}\end{array}}\qquad\quad\checkmark

Answer:
<span>B. 0.119 M</span>
