Answer:
1.239 * 10^8 Kg
Explanation:
Since all the electricity consumed comes from natural gas;
amount of electricity consumed = 700 * 300,000 = 2.1 * 10^8 kWh
So, amount of CO2 consumed is given by;
amount of electricity consumed * amount of CO2 per kWh
Hence,
Amount of CO2 = 2.1 * 10^8 kWh * 0.59 = 1.239 * 10^8 Kg
Answer:
The correct classification of the statement is all compounds.
Explanation:
- All matter is defined as something that entirely has weight and occupies some sought of space. That's why it can't be used to describe the above statement.
- All elements are defined as substances that have an equal number of protons. The atoms in an element contain an exact atomic number.
- All compounds can be defined as a formation that takes place when a variety of atoms are chemically combined. Hence, this explains the answer above.
- All pure substances mean that the substance is not mixed with anything at all. It's just by itself.
Answer:
drip drip water splash (gas)
Explanation:
<u>Answer:</u> The new volume of the gas will be 0.233L.
<u>Explanation:</u>
To calculate the new volume of the gas, we will use the equation given by Boyle's Law.
The above law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
or,
where,
are the initial pressure and volume of the gas.
are the final pressure and volume of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new volume of the gas will be 0.233L.
Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..
Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
