Answer:

Equal volumes of SO2(g) and O2(g) at STP contain the same number of molecules

Explanation:

According to Avogadro Law,

Equal volume of all the gases at same temperature and pressure have equal number of molecules.

This law state that volume and number of moles of gas have direct relation.

When the amount of gas increases its volume will increase and when the amount of gas decreases its volume will decrease.

Mathematical relation:

V ∝ n

V/n = K

K is proportionality constant.

When number of moles change from n₁ to n₂ and volume from V₁ to V₂

expression will be,

V₁/n₁ = K     ,     V₂/n₂ = K

V₁/n₁ = V₂/n₂

Why do scientists use the scientific method?
xeze [42]

Answer:

Scientists use the scientific method because it is evidence-based, standardized and objective in conducting experiments. The scientific method allows scientists to stick to facts and to avoid the influence of preconceived notions and personal biases in research processes, improving the credibility of research findings.

What is the concentration of each ion in a solution that is prepared by dissolving 5.00 g of ammonium chloride in enough water t
sukhopar [10]

The concentration of each ion in the solution of ammonium chloride is:

  • NH₄⁺ = 0.1886 M
  • Cl⁻ = 0.1886 M

To solve this problem, the formulas and the procedures that we have to use are:

  • M = n(solute)/v(solution) L
  • n = m / MW
  • MW= ∑ AWT

Where:

  • M= molarity
  • n = moles
  • m = mass
  • v = volume
  • MW = molecular weight
  • AWT = atomic weight

Information about the problem:

  • m(NH₄Cl) = 5 g
  • v(solution) = 500 ml
  • AWT (N)= 14 g/mol
  • AWT (H)= 1 g/mol
  • AWT (Cl) = 35 g/mol

Converting the volume units from (ml) to (L) we have:

v(solution) = 500 ml * (1 L/1000 ml)

v(solution) = 0,50 L

We calculate the moles of the NH₄Cl from the MW:

MW = ∑ AWT

MW (NH₄Cl)= AWT (N) + AWT (H)*4 + AWT (Cl)

MW (NH₄Cl)= 14 g/mol +( 1 g/mol * 4) + 35 g/mol

MW (NH₄Cl)= 14 g/mol + 4 g/mol + 35 g/mol

MW (NH₄Cl)= 53 g/mol

Having the MW we calculate the moles of NH₄Cl:

n(NH₄Cl) = m(NH₄Cl) / MW(NH₄Cl)

n(NH₄Cl) = m(H2SO4) / MW (H2SO4)

n(NH₄Cl) =  5 g / 53 g/mol

n(NH₄Cl) = 0.0943 mol

Applying the molarity formula, we get:

M(NH₄Cl) = n(NH₄Cl)/v(solution) L

M(NH₄Cl) = 0.0943 mol / 0,50 L

M(NH₄Cl) = 0.1886 M

There are 0.1886 moles of NH₄Cl per liter of solution.

Let's recognize that 1 mol NH₄Cl contains:

  • 1 mol NH₄⁺
  • 1 mol Cl⁻

The concentration of each ion is thus:

(1)*(0.1886 M) = 0.1886 M NH₄⁺

(1)*(0.1886 M) = 0.1886 M Cl⁻

The first step in the two-step process of making a solution is the breakdown of the solute source into ____________."
Troyanec [42]
<h3><u>Answer;</u></h3>

Atomic particles

The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.

<h3><u>Explanation</u>;</h3>
  • Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
  • <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
  • Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
