Answer:

A. True

Explanation:

When a scientific hypothesis is formulated, it must be testable. Testable means that we can conduct a scientific experiment and observe if the results agree or disagree with the proposed hypothesis. Also a scientific hypothesis is falsifiable meaning that if the observation proves that the hypothesis is false then we adhere t that data, we cannot manipulate the data to prove that a hypothesis is always true.

Potassium chlorate decomposes into potassium chloride and oxygen gas. How many grams of oxygen are produced when 1.06 grams of p
kifflom [539]

The amount of oxygen that are produced when 1.06 grams of potassium chlorate decompose completely is 0.64 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

  • n = W/M, where
  • W = given mass
  • M = molar mass

Moles of potassium chlorate = 1.66g / 122.5g/mol = 0.0135mole

Given chemical reaction is:

2KClO₃ → 2KCl + 3O₂

From the stoichiometry of the reaction, it is clear that:

2 moles of KClO₃ = produces 3 moles of O₂

0.0135 moles of KClO₃ = produces (3/2)(0.0135)=0.02 moles of O₂

Mass of oxygen = (0.02mol)(32g/mol) = 0.64 g

Hence produced mass of oxygen is 0.64 grams.

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?
Crank

Answer:

The answer is "\bold{6.26 \times 10^{24} \ molecules \ NH_3}\\\\"

Explanation:

1-mole molecules as per Avogadro number= 6.02 \times 10^{23} \ molecules\\\\

1-mole NH_3 \to 6.02 \times 10^{23} \ molecules\\\\

10.4 \ moles \ of \ \ NH_3 :

\to \frac{ 6.02 \times 10^{23} \ molecules }{ 1 \ mole\ NH_3}  \times 10.4 \ mole \ NH_3\\\\ \to 6.02 \times 10^{23} \ molecules   \times 10.4\\\\\to 62.608 \times 10^{23} \ molecules \\\\\to 6.26 \times 10^{24} \ molecules \ NH_3\\\\
