Answers

Answer 1

Answer:

Their structure is related to their function.

Explanation:

Answer 2

Protein structure is related to their function. Therefore, the correct option is option D among all the given options.

What is protein?

Proteins are huge biomolecular and macromolecular structures made up of one or even more long amino acid residue chains. Proteins serve a wide range of roles inside animals, including catalyzing metabolic events, DNA replication, reacting to stimuli, provides support to organisms and cells including transporting chemicals.

Proteins differ largely in their amino acid sequence, which is determined by the genetic code from their genes and generally culminates with protein folding into such a particular 3D structure that dictates its function. Protein structure is related to their function.

Therefore, the correct option is option D.

Write down your prediction. If you have the colors listed and want a purple color, what would you do?

Answers

The order of increasing polarity of the solvents is; hexane< diethyl ether < acetone < n-propanol < methanol  < water

What is chromatography?

Chromatography literarily means "color writing". It provides a means of separating the components of a mixture based on its components.

The solvent in chromatography is the mobile phase while the adsorbent is the stationary phase. The order of increasing polarity of the solvents is; hexane< diethyl ether < acetone < n-propanol < methanol  < water

If we have a mixture of n-propanol and water, it would be good to add hexane to the mixture for the sake of the elution of non-polar solutes.

The secondary color green may be composed of more than one color while red, blue and yellow are single colors.

What is a redox reaction?

A redox reaction is a type of chemical reaction that involves the transfer of electrons between reactants. The term "redox" comes from the combination of two processes during the reaction: reduction, which involves the gain of electrons by a reactant, and oxidation, which involves the loss of electrons by a reactant.

Why is the above reaction an example of a redox reaction?

The reaction is an example of a redox reaction, where reduction and oxidation occur simultaneously. Chromium is oxidized, while bromine is reduced. The reaction also shows the importance of balancing the number of atoms on both sides of the equation to ensure that the law of conservation of mass is satisfied.

How many grams of FeCo3 will be produced from 57.2g FeCl2

Answers

Answer:

             287.30 g of FeCO₃

Solution:

The Balance Chemical Equation is as follow,

                           FeCl₂ + Na₂CO₃    →    FeCO₃ + 2 NaCl

Step 1: Calculate Mass of FeCl₂ as,

                            Molarity  =  Moles ÷ Volume

Solving for Moles,

                            Moles  =  Molarity × Volume

Putting Values,

                            Moles  =  2 mol.L⁻¹ × 1.24 L

                           Moles  =  2.48 mol

Also,

                            Moles  =  Mass ÷ M.Mass

Solving for Mass,

                            Mass  =  Moles × M.Mass

Putting Values,

                            Mass  =  2.48 mol × 126.75 g.mol⁻¹

                            Mass =  314.34 g of FeCl₂

Step 2: Calculate Mass of FeCO₃ formed as,

According to equation,

          126.75 g (1 mole) FeCl₂ produces  =  115.85 g (1 mole) FeCO₃

So,

               314.34 g of FeCl₂ will produce  =  X g of FeCO₃

Solving for X,

                     X =  (314.34 g × 115.85 g) ÷ 126.75 g

                     X =  287.30 g of FeCO₃

Explanation:

Answer:

The object is moving away from the origin

The object started at 2 meters.

The object is traveling at a constant velocity.

Explanation:

The line on the graph is moving in the upward direction which means the farther right on the graph you go the farther up the line is. The line also has a constant slope which indicates that the object is moving at a constant rate. and if you look at x=0 the y=2 so therefor the object started at 2 meters.
