Answer:
1. 80g
2. 1.188mole
Explanation:
1. We'll begin by obtaining the molar mass of CH4. This is illustrated below:
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
Number of mole of CH4 from the question = 5 moles
Mass of CH4 =?
Mass = number of mole x molar Mass
Mass of CH4 = 5 x 16
Mass of CH4 = 80g
2. Mass of O2 from the question = 38g
Molar Mass of O2 = 16x2 = 32g/mol
Number of mole O2 =?
Number of mole = Mass /Molar Mass
Number of mole of O2 = 38/32
Number of mole of O2 = 1.188mole
The compound that describes the following could be ether. It is because it has a presence of oxygen atom where it is connected in to two groups which is a composition of ether. It does not need hydrogen bonds, that is why ether would be the appropriate answer in the question provided.
please give choices...unless we cannot answer it sorry
Answer: Hard
Explanation:
The upper part of the mantle is hard as it contains thick rock layers. The mantle's upper layer and the crust make up a brittle and rigid rock that's referred to as the Lithosphere.
The upper mantle starts below the Earth crust and then stops at the start of the lower mantle. We should note that the upper mantle results in the movement of the tectonic plates.
Answer:
Explanation:
We have the following chemical reaction:
3 HBr + Al(OH)₃ → 3 H₂O + AlBr₃
This reaction is a double-displacement reaction because the reactant exchange between themselves atoms or group of atoms. The general representation of this kind of reaction is AB + CD → AC + BD
