Which is the largest atom in group IV?

175 ml of a 1.6 m solution of kcl is diluted to a new volume of 1.0 l. what is the new concentration of the solution? (3 points)

djyliett [7]

175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.

Hence, Option (B) is correct answer.

<h3>What is Concentration ?</h3>

Concentration is defined as the measure of how much substance there is mixed with another substance.

<h3>How to find the concentration ?</h3>

To find the concentration use the dilution formula

C₁V₁ = C₂V₂

where,

C₁ = Concentration of starting solution

C₂ = Concentration of final solution

V₁ = Volume of the starting solution

V₂ = Volume of the final solution

Now put the values in above formula we get

C₁V₁ = C₂V₂

1.6 × 0.175 = C₂ × 1.0

0.28 = C₂ × 1.0

C₂ = 0.28

Thus from the above conclusion we can say that 175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.

Hence, Option (B) is correct answer.

Which hypothesis most likely inspired Leeuwenhoek's experimentation with new technology? If the amount of magnification is corre

Serjik [45]

Answer:

If the amount of magnification is correct, then an individual germ can be seen, because individual germs exist but are too small for human eyes.

Explanation:

<em>Leeuwenhoek was the first scientists to experiment with microorganisms using a self-designed single-lens microscope. He described the tiny organisms as 'animacules'. He is known for his pioneer work in the design of the first microscope.</em>

The microscope works by magnifying objects placed on the stage. Germs are microbes that cannot be seen with ordinary eye unless they are magnified appropriately. They are virtually everywhere, including the parts of the world where humans cannot survive.

Hence, the only correct option which most likely inspired Leeuwenhoek's experimentation with technology is the first option. The remaining options are deficient in some ways.

1.5mol C3H8 from C3H8+5O2-->3CO2+4H2O .how many grams of carbon dioxide are produced

koban [17]

Answer:

$\large \boxed{\text{200 g CO}_{{2}}}$

Explanation:

We will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

Mᵣ: 44.01

C₃H₈ + 5O₂ ⟶ 3CO₂ + 4H₂O

n/mol: 1.5

1. Calculate the moles of CO₂

The molar ratio is 3 mol CO₂:1 mol C₃H₈

$\rm \text{Moles of CO}_{2} = \text{1.5 mol C$_{3}$H}_{8} \times \dfrac{\text{3 mol CO}_{2}}{\text{1 mol C$_{3}$H}_{8}} =\text{4.5 mol CO}_{2}$

2. Calculate the mass of CO₂.

$\text{Mass of CO}_{2} = \text{4.5 mol CO}_{2} \times \dfrac{\text{44.01 g CO}_{2}}{\text{1 mol CO$_{2}$}} = \textbf{200 g CO}_{\mathbf{2}}\\\text{The reaction will form $\large \boxed{\textbf{200 g CO}_{\mathbf{2}}}$}$
