8 0

Answer:

STP stands for Standard Temperature and Pressure. NTP stands for Normal Temperature and Pressure.

Explanation:

STP is set by the IUPAC as 0°C and 100 kPa or 1 bar.

NTP is set at 101.325 kPa but uses 20°C as the temperature

Show the calculation of the energy involved in condensation of 150 grams of steam at 100oC if the Heat of Vaporization for water
vaieri [72.5K]

Answer : The energy involved in condensation is, 339 kJ

Explanation :

Formula used :

q=m\times L

where,

q = heat required = ?

L = latent heat of vaporization of water = 2.26kJ/g

m = mass of water = 150 g

Now put all the given values in the above formula, we get:

q=(150g)\times (2.26kJ/g)

q=339kJ

Therefore, the energy involved in condensation is, 339 kJ

Ozone located in the troposphere is _______. A. Considered a pollutant b. Beneficial to living organisms c. Higher in concentrat
Aleonysh [2.5K]

The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

The atmosphere has been divided into five layers based on the availability and the composition of different elements.

<h3>Troposphere</h3>

The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.

The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.

Thus, the presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

The half life of carbon is 5,730 years. What fraction of the original 14/6 C would be in a wooden axe handle that was 17,190 yea
Mariana [72]

Answer:

\frac{1}{8}  

Explanation:

The half-life of carbon (5730 y) is the time it takes for half the carbon to decay.

After one half-life, half (50 %) of the original amount will remain.

After a second half-life, half of that amount (25 %) will remain, and so on.

\text{17 190 y} \times \frac {\text {1 half-life}}{\text{5730 y}} = \text{3 half-lives}  

We can construct a table.

<u>No of half-lives</u>  <u>Fraction remaining</u>

            1                       \frac{1}{2}  

            2                      \frac{1}{4}  

            3                      \frac{1}{8}  

The general formula is

\text{Fraction remaining} = \frac{1}{2^{n}}

where <em>n</em> = the number of half-lives.

Thus, \frac{1}{8} of the original carbon remains after 17 190 y.
