Answer:
I think It's C
Explanation:
due to higher waves can get easy transfers and receive those signals for most things, such as radios, TVs, phone signals etc etc
Colligative
properties calculations are used for this type of problem. Calculations are as
follows:<span>
ΔT(freezing point) = (Kf)m
ΔT(freezing point)
= 1.86 °C kg / mol (0.50 mol/kg)
ΔT(freezing point) = 0.93 °C
Tf - T = 0.93 °C
<span>T = -0.93 °C</span></span>
They have different charges and different masses.
Explanation:
Atom Protons Electrons Neutrons
a 6 6 6
R 7 8 7
The two atoms have different masses and different charges.
The mass of an atom is the sum of its number of protons and neutrons.
The charge is the difference between protons an electrons in the atom.
For atom a;
Mass = 6 + 6 = 12
charge = 6 - 6 = 0
For R:
mass = 7+ 7 = 14
charge = 7 - 8 = -1
We see that they have different masses and different charges.

Answer:
Option B. 96%
Explanation:
To find out the percent yield, let's make a percent:
( Total produced / Theoretical yield ) . 100
(10.31 g / 10.75 g) . 100 = 96 %
