Answer: ending results

Explanation:

Final answer:

The results of an investigation are the observations and data collected during an experiment or research, which may be qualitative or quantitative. For example, the results of a plant growth experiment could include measurements and descriptions of the plants under different light conditions.

Explanation:

The results of an investigation are the findings obtained from carrying out an experiment or research. An investigation seeks to answer a question, test a hypothesis, or solve a problem. The results constitute the data collected and analyzed, which may be quantitative (numerical) or qualitative (descriptive) in nature. For example, if you conduct an investigation to determine the effect of light on plant growth, your results might include measurements of plant height, color intensity, and a description of leaves condition at different light exposures.

You walk in the front door of your home. You smell an onion that someone is cutting in the kitchen. Explain why you are able to smell it, what this process is called, and what other types of substances exhibit this behavior.

Answers

Answer: We are able to smell it because the particles move from their high concentration to low concentration and mix with the gases present in the atmosphere and thus we are able to smell it.

Diffusion is a process in which a movement of substance takes place from a high concentration area to a low concentration area due to the random movement of the particles. Diffusion happens in gases more faster than liquids and solids because of the random movement of their particles.

Other substances exhibiting this behavior is perfume, incense sticks and cooking of food etc.

This is the process of diffusion and is exhibited by gases. The compounds responsible for the smell of onions are released into the air and diffuse through out the house due to random molecular movement. This allows you to smell them at the entrance of your house.

Calculate the morality of each of the following solutions: a. 15.4 g KCl in 289.2 mL solution b. 14.4 g of CaCl2 in 0.614 L solution c. 28.0 mL of 3.00 M H2SO4 diluted to 0.250 L

Answers

The answer is:
a. 0.712 M
b. 0.210 M
c. 0.336 M

Molarity is a measure of the concentration of solute in a solution.
It can be expressed as moles of solute ÷ volume of solution:
c = n ÷V
where:
c - concentration of solute,
n - moles of solute
V - volume of solution

n can be expressed as:
n = m ÷ Mr
where:
n - moles of solute
m - mass of solute
Mr - relative molecular mass

a. We know volume:
V = 289.2 mL = 0.2892 L
We need n and c.

n = m ÷ Mr
m = 15.4 g
Mr (KCl) = 74.55 g/mol
n = 15.4 g ÷ 74.55 g/mol
n = 0.206 mol

Thus,
c = 0.206 mol ÷ 0.2892 L
c = 0.712 mol/L = 0.712 M

b. We know volume:
V = 0.614 L
We need n and c.

n = m ÷ Mr
m = 14.4 g
Mr (CaCl₂) = 110.98 g/mol
n = 14.4 g ÷ 110.98 g/mol
n = 0.129 mol

Thus,
c = 0.129 mol ÷ 0.614 L
c = 0.210 mol/L = 0.210 M

c. We can use formula:
m₁V₁ = m₂V₂
m₁ = 3 M
V₁ = 28 mL= 0.028 L
m₂ = ?
V₂ = 0.250 L
Thus:
3 M × 0.028 L = m₂× 0.250 L
m₂ = 0.336 M

What is Electron Affinity?

The electron affinity of an atom or molecule is defined as electricity launched when electrons are introduced to the outermost shell. Electron affinity increases from left to right across a length.

What's Electronegativity?

Electronegativity is described because the tendency of an atom attracts the bonded pair of electrons of covalent bond to itself. To a degree, the electronegativity Pauling scale is used.

_____ are a type of organic compound.a. Chlorides
b. Carbonates
c. Hydrocarbons
d. Nitrous oxides

Answers

Hydrocarbons are a type of organic compound. The answer is letter C. Hydrocarbons contains a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates and nitrous oxides are not organic compounds but they are inorganic compounds.

A hydrocarbon is a molecule whose structure includes only hydrogen and carbon atoms. Hydrocarbons containing between six and ten carbon molecules are the top components of most fuels. In general, these molecules are burned to produce energy. Examples such include: 1. Methane: A fuel in electrical generation. 2. Propane: Generally used heating and cooking. 3. Butane: Generally used in lighters and aerosol cans. 4.Heptane: The major component of gasoline Hydrocarbons are majorly used as a combustible fuel source and are considered a primary source of energy for contemporary civilizations. Oil is an excellent example of a hydrocarbon fuel currently in use all over the world.
