Chemistry
1 answer:
antiseptic1488 [7]3 years ago
5 0

Answer:

C, 3.00 moles

Explanation:

First, balance the equation.

4Al + 3O2 ---> 2Al2O3

From the balanced equation, assuming Al is limiting, the mole ratio of Al:Al2O3 = 4:2 = 2:1,

meaning every 2 moles of Al used, produces 1 mole of Al2O3.

So, since 1.5 moles of Al2O3 is produced,

the no. of moles of Al used = 1.5 x2

= 3.0 moles

= C

Answer:

CO2

Explanation:

(I Just took the test)

At STP 1 mol=22.4 Liters, so we now know that it is asking for which of the gasses has a molar mass of 44, and CO2 is th only one with that molar mass

When a distance between gas particles increases, the volume of the gas increases true or false??​
Studentka2010 [4]

It is true that when a distance between gas particles increases, the volume of the gas will also increase.

Answer: Option A

<u>Explanation:</u>

The volume of any material can be the space occupied by any material. And the space required by any material to occupy a desired shape or size is determined by its bonding and distance between the particles making that material. If the particles which are soft and small can be compressed easily to occupy very small volume compared to compound made up of hard and large particles.

Along with this, the distance between the neighbouring particles also play a major role, as if we consider a laddo, we can compress it to small size by reducing the distance between neighbouring particles while we will not be able to compress the size or volume occupied by a table as we cannot reduce the distance of particle separation. Thus, it is true that if the distance between gas particles increased then the volume of gas particles will also increase.
