1. 18 L
2. 20.832 L
<h3>Further explanation</h3>
Given
Combustion of ethane
Required
Volume of CO₂
Solution
Avogadro's Law :
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
1. From equation, mol ratio of C₂H₆ : CO₂ ⇒ 2 : 6
so the volume of CO₂ :
= 6/2 x 6 L
= 18 L
2. mol ethane (MW=32 g/mol) :
= mass : MW
= 10 g : 32 g/mol
= 0.31
mol CO₂ :
= 6/2 x 0.31
= 0.93
The volume CO₂(assume at STP) = 20.832 L
The answer sould be Component of Thyroxine, Thyroxine contains iodine and are formed from thyronines, which are composed of two molecules of the amino acid tyrosine. Thyroxine contains four iodine atoms, and triiodothyronine contains three iodine atoms.
Metals are usually givers of electrons.
Answer:
A1 - non hazardous
A2 - irritation
B. Washed off with soap and water
Explanation:
- all materials or chemicals that are not specifically deemed hazardous that is does not cause any harm to the organism in the presence of the material or chemical.
- irritation is a discomfort to an organism which can be caused by an external substance like chemicals.
B. This is the action carried out in order to clean a substance off a surface of a body.
Pressure has the opposite effect on air density increasing the pressure increases the density
