D. The energy obtained from the sun
SUBMIT

Answers

Answer:

c

Explanation:

Thermal Energy has been the type of energy that refers to the kinetic energy of particles contained in a system. Hence, the correct option is (C).

What is thermal energy?

Thermal energy is the energy contained within a system as a result of its temperature. Thermodynamics, a branch of chemistry, states how heat is transmitted through multiple systems and how work is done in the process by the virtue of the first law of thermodynamics.

The thermal energy speeds the movement and collision of the particles present within the system. It is found in electric heat, geothermal, coals, etc. It is due to the kinetic energy that allows the movement of the particles.

Therefore, option C. the kinetic energy contained in the particles results in thermal energy.

when we drop a feather and a stone at the same time from a height the stone reach the faster than a feather

Answers

Answer:

See explanation

Explanation:

When an a heavy object and a light object are thrown down from the same height, the two objects are expected to hit the ground at the same time since the two objects are both accelerated to the same extent (approximately 10m/s^2) under gravity.

However, due to air resistance, the heavier object reaches the ground first before the lighter object.

Hence, when we drop a feather and a stone at the same time from a height the stone will hit the ground faster than the feather.

Explanation:

According to molar concentration, molarity of the resulting solution is 4.32 molar.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution in formula M₁V₁=M₂V₂ gives M₂=6.2×2/3=4.32 M.

Explanation:

The sun is a star that's made up of several gases. It is known to be the most vital source of energy to living things.

Despite the importance of the sun in our lives, it's still harmful when one is exposed to it. They rays of light that's given our by the sun can be harmful to us.

Being exposed to the sun can cause sunburn and this can result in the damage of skin cells and development of cancer. Also, sunlight can lead to early aging as the skin ages faster when one is exposed to the sun.

Furthermore, exposure to sunlight can lead to eye injuries the tissue in our eyes can be damaged by the UV rays. Lastly, it also brings about lowered immune system.

The molal boiling-point and freezing-point constants are different for different solvents.

True or False

Answers

False. The given statement The molal boiling-point and freezing-point constants are different for different solvents is wrong.

Does the solvent affect freezing point depression?

Depression at the Freezing Point. A solution's freezing point is lower than that of the pure solvent. This indicates that for freezing to happen, a solution needs to be cooled to a lower temperature than the pure solvent.

What connection exists between molality and freezing point depression?

The number of solute molecules dissolved in one kilogram of the solvent is known as the molality of the solution, and it is directly inversely related to the drop in freezing point.

What transpires when more solvent is introduced in terms of the freezing point?

The effect of adding a solute to a solvent affects a solution's freezing point in the opposite way that it affects its boiling point. The freezing point of a solution will be lower than that of a pure solvent. The temperature at which a liquid turns into a solid is known as the freezing point.

How many grams of water react to form 4.50 moles of Mg(OH)2?
MgO(s) + H20(1)
Mg(OH)2(s)

Answers

Answer: mass of water is 81.1 g

Explanation: from reaction eguation you see there are equal amounts of water and Mg(OH)2. Then amount of water is 4.50 mol. Molar mass of water is 18.016 g/mol.

Mass m= n·M= 4.50 mol· 18.016 g/mol = 81.1 g

The number of grams of water reacting to form a mass of water is 81.1 g.

What is mass?

Mass is the quantity of matter in a physical body.

The given reaction is

MgO(s) + H₂O(1) → Mg(OH)₂(s)

The number of moles is equal in both sides

The moles of water is 4.50

The molar mass of water is 18.016 g/mol

mass × molar mass

4.50 × 18.016 = 81.1 g.

Thus, the number of grams of water reacting to make a mass of water is 81.1 g.

How much water needs to be added
to 55 mL of 3.0 M stock solution to
produce a .75 M solution?

Answers

Answer:

165 ml

Explanation:

We are given;

Initial volume; V_a = 55 ml

Initial molarity; M_a = 3 M

Molarity of desired solution; M_b = 0.75 M

Volume of desired solution; V_b = (55 + x) ml

Where x is the volume of water to be added.

To solve for V_b, we will use the equation ;

M_a•V_a = M_b•V_b

V_b = (M_a•V_a)/M_b

V_b = (3 × 55)/0.75

V_b = 220 mL

Thus;

(55 + x) = 220

x = 220 - 55

x = 165 mL

Answer:

gotta concert mL to L

3.0=mol/0.055( you multiply morality and liter)

0.165 mol

you divide the mole by the other given molarity

The annual production of sulfur dioxide from burning coal, fossil fuels,
auto exhaust, and other sources is about 130 million tons. When solid sulfur
reacts with oxygen gas it produces gaseous sulfur dioxide. What is the mass
in grams of sulfur that is needed to produce 2.30 Kg of sulfur dioxide?
*Don’t forget from your metric you were given that 1 Kg = 1000 g.

Answers

Answer:

1150g

Explanation:

The equation for producing sulphur dioxide is [tex]S + O_{2} ==> SO_{2}[/tex]

Looking at the ratios, you need 1 mole of sulphur for every 1 mole of sulphur dioxide

Sulphur dioxide has a molar mass of 32 + (2 x 16) = 64g

2.30 x 1000 = 2300

2300 / 64 = 35.9375

35.9375 x 32 = 1150g of sulphur
