<u>Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3>Explanation:</h3>

<u>Step 1: Define</u>

103.4 g H₂S (Sulfuric Acid)

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of H₂S - 2(1.01) + 32.07 = 34.09 g/mol

<u>Step 3: Convert</u>

  1. Set up:                              \displaystyle 103.4 \ g \ H_2S(\frac{1 \ mol \ H_2S}{34.09 \ g \ H_2S})(\frac{6.022 \cdot 10^{23} \ molecules \ H_2S}{1 \ mol \ H_2S})
  2. Multiply:                                                                                                            \displaystyle 1.82656 \cdot 10^{24} \ molecules \ H_2S

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 4 sig figs.</em>

1.82656 × 10²⁴ molecules H₂S ≈ 1.827 × 10²⁴ molecules H₂S

An example of a scientific law is the law of conservation of mass, which states that matter is neither created nor destroyed in
Amanda [17]

Answer:A) It was developed from past observations- true

It is subject to experimentation and revision.- false

It explains why mass is conserved- false

It predicts future observations-true

Explanation:

Before a hypothesis is proclaimed to be a law in science, numerous observation must have confirmed its validity and rigorous experimentation under carefully controlled conditions usually precedes the acceptance of a hypothesis as a law. The law of conservation of mass was developed from numerous past observation that proved its validity.

How do you balance the following solution Zn(s)+HCI(aq)—&gt;ZnCI2 (aq) + H2(g)
Ierofanga [76]

<u>Answer:</u> The atoms of every element on both the sides of the reaction must be same.

<u>Explanation:</u>

We are given a chemical equation and we need to balance it. Every equation follows Law of Conservation of mass.

This law states that in a chemical reaction, the number of atoms of each element must be same on both the sides of the equation.

For the given chemical equation:

Zn(s)+HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)

On reactant side:

Number of zinc atoms = 1

Number of hydrogen atoms = 1

Number of chlorine atoms = 1

On product side:

Number of zinc atoms = 1

Number of hydrogen atoms = 2

Number of chlorine atoms = 2

As, the number of hydrogen and chlorine atoms on reactant and product side is not same, so we need to add a stoichiometric coefficient in-front of HCl on the reactant side. The balanced chemical equation becomes:

Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)
