Explanation:
Mark me brainliest pls
Carbon dioxide molecules don't directly react with the sunlight but they can absorb the energy in the form of infrared waves when it is emitted after reflection through the Earth's surface.

This is defined as a variant form of a gene. We were told that allele for white wool is dominant to the allele for black wool and two heterozygous sheep mated.
When we cross Ww and Ww we get WW, Ww, Ww, ww. Since white is dominant then the percentage is 3/4 = 75 percent.

The cell notation of the redox reaction between Cu and ClO₃⁻ is:
Cu/Cu²⁺//ClO₃⁻//Cl⁻/PtWhat is a voltaic cell?A voltaic cell or electrochemical cell is a device which produces electricity from chemical reactions occuring within the cell.
The reactions occuring in a voltaic cell are redox reactions.
Oxidation occurs at the anode while reduction occurs at the cathode.
In the given reaction between Cu and ClO₃⁻ as shown below:
ClO₃⁻ (aq) + 3 Cu (s) + 6H⁺ (aq) → Cl⁻ (aq) + 3 Cu²⁺ (aq) + 3 H₂O (l)Cu is oxidized as follows: 3 Cu (s) → 3 Cu²⁺
ClO₃⁻ is reduced as follows: ClO₃⁻ (aq) → Cl⁻ (aq)
The voltaic cell notation is as follows where Pt is used as an inert electrode in contact with the ClO₃⁻ and Cl⁻:
Cu/Cu²⁺//ClO₃⁻//Cl⁻/PtTherefore, the cell notation of the redox reaction between Cu and ClO₃⁻ shows that Cu is oxidized while ClO₃⁻ is reduced.

Which of the following is a reasonable explanation for the effect that stirring or agitation has on the dissolution rate?
A.
The water molecules have more kinetic energy and have a greater chance of interacting with (and dissolving) the potassium iodide.
B.
The water molecules have an increased charge, since stirring removes electrons from the molecules. This increases the chance of a potassium ion being attracted to water.
C.
Stirring converts large amounts of energy into heat from friction and the heat increases the dissolution rate.
D.
Stirring breaks the bonds between water molecules so that they are free to bond with the potassium and iodine ions.
Answers
The water molecules have more kinetic energy and have a greater chance of interacting with (and dissolving) the potassium iodide.
What is the effect of stirring on the dissolution rate?Stirring breaks a solute into smaller pieces which increases its surface area as well as its rate of dissolution. Stirring brings unused portions of the solvent in contact with the solute which allows the solute to dissolve faster.

D) - and uncertain
Answers
What's a combustion
It means hydrocarbon burns in presence of excess oxygen to produce carbon dioxide and heat
Hence it's exothermic∆H=+veAs solid state is converted to gaseous so randomness increases hence it's spontaneous
Combustion is the process of combining with oxygen to form water and carbon dioxide. It is an exothermic reaction and will release energy. Thus delta H for combustion is negative.
What is enthalpy change ?Enthalpy change of reaction is the change in heat absorbed or released by a reaction. If heat is absorbed by the system , the reaction is called endothermic and the change in enthalpy delta H is positive.
For a reaction which release energy, the change in enthalpy delta H will be negative and thus the reaction is said to be exothermic. Combustion is an exothermic reaction.
During combustion new bonds are formed between carbon and oxygen and carbon and hydrogen. Thus bond making is happend more than bond breaking. Bond breaking needs much energy than bond making.
Hence, the released energy is more form combustion and enthalpy change is negative. The process needs no more energy thus the reaction is spontaneous. Thus option C is correct.

Does gravity give objects their mass
Answers
Answer:
No
Explanation:
Mass affects the amount of gravity that acts on an object.
Answer:
Mass is determined by the quantity of matter in a physical object.
Mass is how much space something takes up, while weight is how much an object is acted on by a force because of gravity.
Explanation:
Gravity does not determine the mass of an object. For example, an object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that determines the strength of this force.

For an impure sample of potassium hydrogen phthalate, the percentage of potassium hydrogen phthalate is
m'=39.3%
What is the percentage of potassium hydrogen phthalate if 2.81 g of the mixture required 35.61 mL of 0.152 mol/L NaOH to reach the end point?Generally, the equation for the mol base is mathematically given as
mol base = M*V
mol base = 0.152*35.61
mol base = 5.41272 mmol
In conclusion
mass = mmol/1000*MW
m== 5.41272 /1000*204.22

What is the RGB model?RGB is a color model with which it is possible to represent a color by mixing by adding the three primary colors of light.
A special feature of this model is that it is not a reference point for defining the color red, green, or blue because the same RGB values can display noticeably different colors on different devices.
To form a color, it must be taken into account that in the RGB model the incidence of each color (red, green or blue) is measured on a scale that goes from 0 to 255.
