Answer:

Sand absorbers the water

Explanation:

On other days, however, when winds blow surface water toward land, the water can't just pile up on the beach, so water near the bottom has to compensate, moving offshore. ... One measures the speed and direction of flowing water by reflecting sound off particles carried by the currents.

Why is thermal energy from the sun transferred to Earth through electromagnetic waves, instead of any other type of thermal ener

nlexa [21]

Answer: B) Electromagnetic waves can travel through empty space.

Explanation:

Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.

Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.

Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.

Consider this question: What is the molarity of KMnO4 in a solution of 0.0908 g of KMnO4 in 0.500 L of solution?

natita [175]

Answer:

0.0011 M.

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

n = moles of solute ,

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

w = given mass of KMnO₄ = 0.0908 g

and ,

V = 0.500 L

Since ,

we know ,

m = Molecular mass of KMnO₄ = 158 g/mol

using , the above formula to calculate the moles ,

n = w / m = 0.0908 g / 158 g/mol = 0.00057 mol

now , calculating the molarity as ,

M = n / V = 0.00057 mol / 0.500 L = 0.0011 M.

Physical Properties: Sodium bicarbonate is an odorless, white crystalline solid or fine powder. It has a slightly alkaline taste. Its density is 2.20 g mL-1 and it decomposes in temperatures above 50 ºC. The decomposition yields to sodium carbonate. It is highly soluble in water and poorly soluble in acetone and methanol. It is insoluble in ethanol.

Chemical Properties: Sodium bicarbonate is an amphoteric compounds, it means the compound has a character acids an basic at the same time. It is highly soluble in water, resulting in a slighty alkaline solution.

i hope this part helps i will continue to research on Toothpaste's properties

Determine whether each of the following is a strong acid, a weak acid, or a species with negligible acidity.Drag the appropriate

sp2606 [1]

Answer:

CH₃NH₃⁺ is a weak acid.

HPO₄²⁻ has a negligible acidity.

CH₄ has a negligible acidity.

HNO₂ is a weak acid.

Explanation:

There are 7 strong acids: HCl, HBr, HI, HNO₃, H₂SO₄, HClO₃, HClO₄. The rest of the acids are weak.

CH₃NH₃⁺ is a weak acid, according to the following equation:

CH₃NH₃⁺ ⇄ CH₃NH₂ + H⁺

HPO₄²⁻ can act as an acid or as a base:

<u>Acid reaction:</u> HPO₄²⁻ ⇄ PO₄³⁻ + H⁺

<u>Basic reaction:</u> HPO₄² + H₂O ⇄ H₂PO₄⁻ + OH⁻

Given Kb > Ka, HPO₄²⁻ has a negligible acidity.

CH₄ cannot release nor accept H⁺ so it has a negligible acidity.

HNO₂ is a weak acid, according to the following reaction:

HNO₂ ⇄ H⁺ + NO₂⁻
