How many moles of SnF₂ will be produced along with 48 grams of H₂? *

Chemistry
1 answer:
Oxana [17]3 years ago
6 0

Answer:

The correct option is;

24 moles

Explanation:

Here, we have the reaction as follows;

Sn(s) + 2HF(g) → SnF₂ (s) + H₂ (g)

Therefore, one mole of Sn reacts with 2 moles HF to form one mole of SnF₂ and one mole of H₂

Molar mass of H₂ = 2.01588 g/mol

Therefore, the number of moles of H₂ in 48 grams of H₂ is given by the relation;

Number \ of  \ moles \ of \, H_2 = \frac{Mass \ of  H_2}{Molar \ Mass \ of  H_2}=\frac{48}{2.01588} = 23.8109 \ moles \approx 24 \ moles

Since one mole each of SnF₂ and H₂ are produced, the number of moles of SnF₂ produced = 24 moles.

The number of moles of SnF₂ that will be produced is 24 moles.

The question is incomplete, this is the complete question;

In the process of attempting to characterize a substance, a chemist makes the following observations. Which are physical properties and which are chemical properties?

(a) The substance is a silvery white, lustrous metal.

(b) The substance melts at 649 ∘C

(c) The substance boils at 1105 ∘C.

(d) The density of the substance at 20 ∘C is 1.738 g/cm³.

(e) The substance burns in air, producing an intense white light.

(f) The substance reacts with chlorine to give a brittle white solid.

(g) The substance can be pounded into thin sheets or drawn into wires.

(h) The substance is a good conductor of electricity.

Answer:

(a) Physical

(b) Physical

(c) Physical

(d) Physical

(e) Chemical

(f) Chemical

(g) Physical

(h) Physical

Explanation:

(a) The substance is a silvery white, lustrous metal - is appearance which is physical.

(b) The substance melts at 649 ∘C metling point is a physical measurement

(c) The substance boils at 1105 ∘C boiling point is a physical measurement

(d) The density of the substance at 20 ∘C is 1.738 g/cm3 how heavy a substance is,is physical.

(e) The substance burns in air, producing an intense white light. Burning is a chemical change. It is a reaction of a substance with oxygen

(f) The substance reacts with chlorine to give a brittle white solid. This is a chemical reaction as the question says.

(g) The substance can be pounded into thin sheets or drawn into wires. Ductility is a physical change, the substance remains chemically unchanged

(h) The substance is a good conductor of electricity. Any conductivity is physical, the substance remains chemically unchanged

How did the discovery of isotopes help to lead to a revised model of atomic structure?
Arte-miy333 [17]
Dalton postulated that atoms of the same elements had the same mass while atoms of different elements had different masses. 

The discovery of isotopes revealed that atoms of the same element did not necessarily have same masses, they could have different masses.

Therefore, the modern periodic table that we use nowadays contains the average atomic mass of all the isotopes found for a given element.
