Answer:

.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.

Explanation:

N2O4(g)<--------> 2NO2(g)

At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.

Sergio039 [100]
A plant is a living organism that uses chlorophyll in the chloroplasts to perform photosynthesis. The chemical equation of photosynthesis is
Sunlight(Photons)+ CO2+2H2O ----->C6H12O6+H2O+O2.(Not balanced) The reactants are carbon dioxide and water. The products are water and glucose with oxygen as a waste product.Photosynthesis can make a plant form a closed cycle as plants need to respire with oxygen which is a waste product of one of their reactions.

How many atoms are there in 3.559*10^-6 mol of krypton?
algol [13]

Answer:

The answer is

<h2>2.143 \times  {10}^{18}  \:  \: atoms</h2>

Explanation:

To find the number of atoms given the number of moles we use the formula

N = n × L

where

N is the number of entities

n is the number of moles

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

n = 3.559 \times  {10}^{ - 6}  \: mol

Substitute the values into the above formula and solve

That's

<h3>N  = 3.559 \times  {10}^{ - 6}  \times 6.02 \times  {10}^{23}  \\  = 2.1425 \times  {10}^{18}</h3>

We have the final answer as

<h3>N  = 2.143 \times  {10}^{18}  \:  \: atoms</h3>

Hope this helps you

Which statements about β turns are correct? Their purpose is to reverse the direction of the polypeptide chain. There are two ty
zhuklara [117]

Answer:

The correct answer is - 1, 2, and 4 statements.

Explanation:

Beta and gamma turns are common plots or turns in proteins and contain intra-turn hydrogen bonds. This hydrogen bond is present between CO of residue i and NH of residue i+3 that holds the confirmation in beta turns.

Beta turns, assist the protein to get their globularity, as the aim of beta turns is to reverse the direction of the polypeptide. The two main of beta turns are type-I and type-Il. and their minor images are type-I and type-Il.

Thus, the correct answer is - 1, 2, and 4 statements.

Answer:
               Cp  =  0.093 J.g⁻¹.°C⁻¹
Solution:

The equation used for this problem is as follow,

                                                  Q  =  m Cp ΔT   ----- (1)

Where;
            Q  =  Heat  =  300 J

            m  =  mass  =  267 g

            Cp  =  Specific Heat Capacity  =  ??

            ΔT  =  Change in Temperature  =  12 °C

Solving eq. 1 for Cp,

                                 Cp  =  Q / m ΔT


Putting values,
                                 Cp  =  300 J / (267 g × 12 °C)

                                 Cp  =  0.093 J.g⁻¹.°C⁻¹
