Answer:

[tex]HI(aq)+NaOH(aq)\rightarrow NaI(aq)+H_2O(l)[/tex]

Explanation:

Hello there!

In this case, for this neutralization reaction, it is possible to realize that one the neutralization products is water (pH=7) and the other one is the salt coming up from the cation of the NaOH and the anion of the HI:

[tex]HI(aq)+NaOH(aq)\rightarrow NaI+H_2O[/tex]

Moreover, since the solubility of NaI is large in water, we infer it remains aqueous whereas the water is maintained as liquid:

[tex]HI(aq)+NaOH(aq)\rightarrow NaI(aq)+H_2O(l)[/tex]

Which is also balanced as the number of atoms of all the elements is the same at both sides.

Best regards!

The correct option is (a) 635 nm.

Given,

          λ=6.36×10−7 m

         Let  f = the frequency = 4.72 × [tex]10^{14}[/tex] Hz

         Let  λ=  the unknown wavelength

Now apply formula of wavelength

                      λ = C /f

               λ = [tex]\frac{3.00 * 10^{8 }m/s }{4.72 * 10^{14} Hz}[/tex]

              λ = 6.36 × [tex]10^{-7}[/tex] m

Answer:

C. Methane

Explanation:

Hopefully this isnt too late!

Answer:

C. Methane

(Photo for proof at the bottom.)

Explanation:

All amino acids contain an amino group, a carboxyl group, and an R group. An amino group consists of NH2. A carboxyl group consists of COOH. And an R group usually consists of a hydrogen or carbon atom bonded to the amino acid. Methane only consists of CH4, which clearly does not meet the criteria of an amino acid.

Answer:

Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body.

Explanation:

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Combined gas law states that "the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant".

Temperature ,T₁ = 20⁰C = 20+273.15K = 293.15K

Temperature, T₂ = 40⁰C = 40+273.15K = 313.15K

According to combined gas law,

P₁V₁/n₁T₁ = P₂V₂/n₂T₂

Where, n is moles of substance

P is pressure

P and n are considered to be a constant.

Thus, V₁/T₁ = V₂/T₂

V₁ = V₂T₁/T₂

V₁ = ?,

V₂ = 585mL = 585mL x 293.15K/313.15K

V₁ = 548mL

Hence, the original volume of the helium gas is 548mL.

"Pressure is the force of all the gas particle/wall collisions divided by the area of the wall."

"Volume is the amount of space occupied by a substance."

"Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius."

Answer: The final pressure is 1600 torr.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay Lussac' Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=800.0torr\\T_1=27^oC=(27+273)K=300K\\P_2=?\\T_2=327^0C=(327+273)K=600K[/tex]

Putting values in above equation, we get:

[tex]\frac{800.0torr}{300K}=\frac{P_2}{600K}\\\\P_2=1600torr[/tex]

Thus the final pressure is 1600 torr.

Answer:

For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively

Explanation:

The computation of the mass of each element is given below:

As we know that

A1 mole of ammonium nitrate i.e. 2 mol N, 4 mol H, 3 mol

Now we multiply each of above  by the molar masses

For N

= 14.0 g/mol × 2

= 28.0 gN

For H

= 1.0 g/mol × 4

= 4.0 gN

ANd, for O

= 16.0 g/mol × 3

= 48.0 gN

Hence, For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively

Explanation:

HCl(l) ===> H+ + cl-

HCl is a very strong acid. Almost all of it will decompose to the right. That means the concentration of H+ is 0.00530

pH = - log [H+]

pH = - log[0.00530]

pH = - - 2.2757

pH = 2.2757

Rounded this 2.28

Answer:D

Explanation:

First, make sure to balance your equation.

3H2(g) + N2(g) ⇄ 2NH3(g)

Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.

Kc = [NH3]^2 / [H2]^3[N2]

The reaction between nitrogen and hydrogen is called the Haber process. Kc for the reaction is the ratio of the concentration of ammonia to nitrogen and hydrogen.

An equilibrium constant, kc is the concentration proportion of the products to the concentration of the reactants raised by their respective coefficients.

The balanced chemical Haber process is given as:

[tex]\rm 3H_{2}(g) + N_{2}(g) \leftrightharpoons 2NH_{3}(g)[/tex]

Now, the equilibrium constant for the reaction can be given as:

[tex]\rm Kc = \rm \dfrac{[NH_{3}]^{2}}{[H_{2}]^{3}[N_{2}]}[/tex]

Therefore, the ratio of the concentration of ammonia to hydrogen and nitrogen gives the equilibrium constant.

Answer:

False.

Explanation:

The given statement asserts a false claim because the equator is the region that receives maximum sunlight. The equator is placed right below the sun and thus, it tends to receive the maximum radiation across the year. While the poles are the coldest regions of the Earth because due to Earth's titled axis, they receive very few sun rays for a certain time of the year. Thus, if we move away from the equator, we are likely to receive less radiation from the sun as the sun keeps getting farther while moving away from the equator.
