Answer:
the first three statement
Explanation:
Answer: B. you will need 53.2 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
The balanced reaction is:
2 moles of aluminium react with= 3 moles of chlorine
Thus 0.5 moles of aluminium react with= moles of chlorine
Mass of chlorine=
2 moles of aluminium produce = 2 moles of aluminium chloride
Thus 0.5 moles of aluminium react with= moles of aluminium chloride
Mass of aluminium chloride=
Thus 53.2 g of chlorine is used and 66.7 g of aluminium chloride is produced.
The partial pressure of gas C is 0.54atm. The correct option is D.
<h3>What is partial pressure?</h3>
The pressure that one of the gases in a mixture would exert if it were in the same volume on its own.
The total pressure of A, B and C is 6.11 atm.
The partial pressure of A is 1.68 atm
The partial pressure of B is 3.89 atm.
Total pressure = sum of partial pressures of all the gasses in that mixture
6.11atm = 1.68atm + 3.89atm + Pc
Pc = 6.11atm - (1.68 + 3.89) = 0.54atm
Thus, the partial pressure of C is 0.54atm. The correct option is D.

<u>Answer</u>:
Indirect evidence used to study Earth's interior are
- analysis of several seismographs
- location of an earthquake's epicentre
- identification of seismic wave direction
<u>Explanation</u>:
The earth is mainly divided into 3 layers. These are the crust, mantle and the core. Further, the interior part of the earth cannot be studied directly and the direct evidence explains the composition of rocks.
The seismic waves help with the understanding of indirect evidence. The seismic waves are the energy that travels through different layers of the earth.It is caused due to volcanoes, earthquakes, landslides etc. Thus, analysis of several seismographs, identifying the direction the of seismic wave and location of earth’s epicentre helps to study earth's interior.
