Answer:

1.12 g of oxygen.

Explanation:

First step is to determine the decomposition reaction:

Ammonium perchlorate → NH₄ClO₄

2NH₄ClO₄ (s) →  N₂(g) + Cl₂(g) + 2O₂(g) + 4H₂O(g)

We define the moles of the reactant:

4.1 g . /117.45 g/mol = 0.0349 moles

As ratio is 2:2, If I use 0.0349 moles of perchlorate I would produce the same amount of moles of oxygen.

0.0349 mol of O₂ are produced by the reaction

We convert to mass:  0.0349 mol . 32 g /1mol = 1.12 g

nexus9112 [7]

Here we have to choose the right option which tells the moles of CaCl₂ will react with 6.2 moles of AgNO₃ in the reaction

2AgNO₃ + CaCl₂→ 2AgCl + Ca(NO₃)₂

6.2 moles of silver nitrate (AgNO₃) will react with B. 3.1 moles of calcium chloride (CaCl₂).

From the reaction: 2AgNO₃ + CaCl₂→ 2AgCl + Ca(NO₃)₂

Thus 2 moles of AgNO₃ reacts with 1 mole of CaCl₂

Henceforth, 6.2 moles of AgNO₃ reacts with \frac{6.2}{2} = 3.1 moles of CaCl₂.

1 mole of CaCl₂ reacts with 2 moles of AgNO₃. Thus-

A. 2.2 moles of CaCl₂ will react with 2.2×2 = 4.4 moles of AgNO₃.

C. 6.2 moles of CaCl₂ will reacts with 6.2×2 = 12.4 moles of AgNO₃.

D. 12.4 moles of CaCl₂ will reacts with 12.4 × 2 = 24.8 moles of AgNO₃

Thus the right answer is 6.2 moles of AgNO₃ will react with 3.1 moles of CaCl₂.

5. Which statement is true about electronegativity?
Anit [1.1K]

Answer:

Electronegativity generally increases from left to right across a period,

Explanation:

The true statement from the given choices is that electronegativity generally increases from left to right across a period.

Electronegativity is the measure of the relative tendency with which an atom of the element attract valence electrons in a chemical bond.

Across a period electronegativity increases from left to right and decreases down the group.

This is due to reduction in metallic properties as we move across the period from left to right.

Which of the following would be a result of increased solar activity?
scoundrel [369]
<span>The question is asking us "Which of the following would be a result of increased solar activity?" The Sun is extremely hot, and when it is warm on Earth, the heat has as it source in the Sun. Therefore, an increased solar activity would mean increased temperature on Earth - longer summers and shorter winters, and warmer sea temperatures. The best answer is : B. Warmer-than-normal sea surface temperatures </span>
