When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is 
.
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,
Answer:
The pressure will increase due ot expnasion of gasses in a closed sealed tube tube .
Explanation:
<span>According to the law of conservation of energy and due that all the chemical energy is converted to other three types of energy, the total sum of these three energies after the explosion must be the same than the initial energy, that is 100 units.</span>
<u>Answer:</u>
<em>The sign of work for this process will be Negative.</em>
<em></em>
<u>Explanation:</u>
Work done by the system on the surroundings is negative
So, If work is done on the system, its sign is positive. If work is done by the system, its sign is negative
Here we see the system that is argon gas is expanding and the work is done by the system into the surroundings (vessel) and the sign is Negative
Therefore, the sign of work for this process will be Negative.
When the concentration is expressed in percentage, you simply have to divide the amount of substance to the total amount of the mixture, then multiply it by 100. In this case, when you want to find the percentage of P in the sample, the solution is as follows:
%P = 7.5 g/100 g * 100 =<em> 7.5%</em>
