Answer:
There are 13 numbers in an aluminum atom and 13 electrons.
Explanation:
This is because the atomic number equals the number of protons and the atomic number of Al is 13. The number of electrons also equals the number of protons.
The number of units of aluminum chloride (AlCl₃) that can be produced from 30 atoms of aluminum (Al) is 30 units
The balanced equation for the reaction is given below:
2Al + 3Cl₂ — > 2AlCl₃
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
With the above information, we can determine the number of units of AlCl₃ that can be produced by the reaction of 30 atoms of Al. This can be obtained as follow:
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
Therefore,
30 atoms of Al will also react to produce 30 units of AlCl₃.
Thus, 30 units of AlCl₃ were obtained from the reaction.

Redshift is said to be experienced when the light or any other electromagnetic radiations from an object undergo an increase in the wavelength but it does not mean that the light literally becomes red.
Redshift occurs due to the expansion of space. It means the farther away the galaxy is from us, the more space it has expanded in the time.
Because as the light left the galaxy, more of the light has been stretched and so more redshifted the light is.
Explanation:
For the given reaction:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
where x and y are order wrt to and
According to collision theory , the molecules must collide for a reaction to take place. According to collision theory , the rate of a reaction is proportional to rate of collision of reactants.
Thus with an increase in concentration of reactants , the rate of reaction also increases. This is because if the concentration of reactants increases , the chances of collision between molecules also increases and thus more products wil be formed which in turn increases the rate of reaction.
Answer:
Mole fraction of methanol will be closest to 4.
Explanation:
Given, Mass of methanol = 128 g
Molar mass of methanol = 32.04 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given, Mass of water = 108 g
Molar mass of water = 18.0153 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
<u>Mole fraction of methanol will be closest to 4.</u>
