Answer : The correct option is, (D) 3 : 1

Explanation :

The balanced chemical equation will be,

$CS_2+3Cl_2\rightarrow CCl_4+S_2Cl_2$

By the stiochiometry, 1 mole of carbon sulfide react with 3 moles of chlorine to give 1 mole of carbon tetrachloride and 2 moles of sulfur chloride.

From the balanced chemical reaction, we conclude that the mole ratio of $Cl_2$ to $CCl_4$ is, 3 : 1

Hence, the correct option is, (D) 3 : 1

CS₂ + Cl₂<span> </span>→ CCl₄ + S₂Cl₂<span> [unbalanced equation]

</span>CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂ [balanced equation]

∴ the mole ratio of Cl₂ : CCl₄ is 3 : 1 (option D)

What mass of chromium would be produced from the reaction of 57.0 g of potassium with 199 g of chromium(II) bromide according to

fredd [130]

Answer:

Mass of Chromium produced = 37.91 grams

Explanation:

2K + CrBr₂ → 2KBr + Cr

2mole 1 mole 1 mole

mass of Potassium = 57.0 grams

molar mass of Potassium = 39.1 g/mol

no of moles of Potassium = 57.0 / 39.1 = 1.458 moles

mass of CrBr₂= 199 grams

molar mass of CrBr₂ = 211.8 gram/mole

no of moles of CrBr₂ = 199 / 211.8 = 0.939 mole

From chemical equation

1 mole of CrBr₂ = 2 moles of K

∴ 0.939 moles of CrBr₂ = ?

⇒ 0.939 x 2/1 = 1.878 moles of K

1.878 moles of K is needed, but there is 1.458 moles of K. So, Potassium is completed first during the reaction . Hence, Potassium is limiting reagent. and CrBr₂ is excess reagent .

From chemical equation

2 moles of K = 1 mole of Cr

∴ 1.458 moles of K = ?

⇒ 1.458 x 1/ 2 = 0.729 moles of Cr

no of moles of Cr formed = 0.729 moles

molar mass of Cr = 52.0 g/mol

mass of one mole of Cr = 52.0 grams

mass of 0.729 moles of Cr = 52.0 x 0.729 = 37.908 grams

mass of Chromium produced = 37.91 grams

Explain why a potassium atom would not bond with a calcium atom?

docker41 [41]

Answer:

Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.

Select the correct statement (2.5 points) (A) Elements in the same row are similar in size. (B) Elements in the same column have

Mrrafil [7]

Answer:

Explanation:

We are talking about the periodic table in which elements where put under different rows and columns according to their atomic number (number of protons) in ascendant order.

In rows or periods we can find trends in some properties like atomic radius, electronegativity, etc...). So they are not similar in size. Option A is a false statement.

Also, they were organized in groups or columns according to their similar electronic configuration and chemical properties (like noble gases, halogens, etc...) This means option B is the correct statement.
