Answer:

The correct answer is sugar.

Explanation:

The sugar mentioned is the treatment in the given experiment. The plain water possesses a freezing point of zero degree Celsius. However, water treated with sugar or sugar water exhibits a lower freezing point in comparison to pure water. The treatment here, that is, the sugar makes lowering or depression of the freezing point of water. Water is the solvent and the sugar is the solute here.

The amount of radioactive carbon-14 in a sample is measured using a Geiger counter, which records each disintegration of an atom
sergij07 [2.7K]

Answer:

4121 years

Explanation:

From;

0.693/t1/2 = 2.303/t log No/N

t1/2= half life of the carbon-14

No= count rate of the living tissue

N= count rate of the sample

t = age of the sample

0.693/5730 =2.303/t log (13.5/8.2)

1.21 * 10^-4 = 2.303/t * 0.2165

1.21 * 10^-4 = 0.4986/t

t = 0.4986/1.21 * 10^-4

t = 4121 years

A sample of 0.010 mole of oxygen gas is confined at 127 °c and 0.80 atmosphere. what would be the pressure of this sample at 27
devlian [24]
First,let's assume ideal gas behavior for simplicity. This is a special case because the volumes of the two states are equal. At constant volume, we can use the Gay-Lussac equation:

P₁/T₁ = P₂/T₂

(0.8)/(127+273) = (P₂)/(27+273)
Solving for P₂,
P₂ = 0.6 atm

<em>Thus, the answer is 0.6 atm.</em>

Neon has 8 electrons in it's outer shell. Does it need to bond? Why or why not?
Lena [83]
No.!!
As it has full filled valence electrons, they can't form bonds, due to lack of vacant electrons.

Hope this helps!
