Answer:

A carbon dioxide

its how carbon is transferred

Carbon cycle is the process of balancing the amount of carbon in the atmosphere and what is present in plants and animals. In carbon cycle, carbon is transferred in the form of carbon dioxide from animals to plants.

Carbon cycle is a geochemical cyclic process by which the carbon gas is exchanged between the atmosphere and biosphere. Carbon is the main content of all biological materials as well as living.

These events in carbon cycle balance the amount of carbon in atmosphere and biosphere to sustain life. Thus the wasted carbon from animals are recycled back to the atmosphere in the form of carbon dioxide.

We intake oxygen and release carbon dioxide. The released carbon dioxide is uptaken by plants and used for photosynthesis. By the process of photosynthesis, plants are making glucose and energy.

Therefore, In the carbon cycle, carbon is transferred from animals to plants in the form of A. carbon dioxide.

Answer:

Different visible waves show different colors

In the electromagnetic spectrum, different  visible waves show different colors.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Explanation:

in one mole of phosphoric acid you have 3 mol hydrogen, 2 mol phosphorus, and 4 mol oxygen. just multiply everything by 2 and you get 2 mol of phosphoric acid

Answer:

d) 2

Explanation:

We are given;

n = 4, l = 1, m = -1

We can tell that is is an orbital with sub shell as 3P.

Now, from Paul's exclusion principle, each orbital will have maximum of 2 electrons of each π with a spin of +½ and -½.

Since the maximum is seen to be 2, then option D is correct.

Answer:

2.place value is 70 000 00

Answer:

0.019 atm / hr

Explanation:

Initial Concentration (Pressure) [A]o = 0.473 atm

Final Concentration (Pressure) [A] = 0.376 atm

Time = 5.6 hours

The breakdown follows first order kinetics.

The integrated rate law for a first order reaction is given as;

ln[A] = ln[A]o - kt

ln(0.376) = ln(0.473) - k (5.6)

ln(0.376) - ln(0.473) = - 5.6 k

5.6 k = 0.23

k = 0.0411 hr⁻¹

The rate of decomposition is given as;

Rate = k [X]

Where [X] represents Concentration (Pressure) = 0.473 atm

Rate = 0.0411 * 0.473 = 0.019 atm / hr

Answer: The products of electrolysis are Zn(l) and [tex]Cl_2[/tex] gas

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.  

In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

[tex]ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-[/tex]

At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]

At cathode : [tex]Zn^{2+}(l)+2e^-\rightarrow Zn(l)[/tex]

Yes, As the gravity/distance increases between two objects, the gravitational pull between them weakens/strengthens.

There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.

Answer:

Option D. 7.56 g of Hg.

Explanation:

The balanced equation for the reaction is given below:

4HgS + 4CaO —> 4Hg + 3CaS + CaSO₄

Next, we shall determine the mass of CaO that reacted and the mass of Hg produced from the balanced equation. This is can be obtained as follow:

Molar mass of CaO = 40 + 16

= 56 g/mol

Mass of CaO from the balanced equation = 4 × 56 = 224 g

Molar mass of Hg = 200.59 g/mol

Mass of Hg from the balanced equation = 4 × 200.59 = 802.36 g

SUMMARY

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Finally, we shall determine the mass of Hg produced by the reaction of 2.11 g of CaO. This can be obtained as follow:

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Therefore, 2.11 g of CaO will react to produce = (2.11 × 802.36)/224 = 7.56 g of Hg.

Thus, 7.56 g of Hg were obtained from the reaction.

Explanation:

What would you expect to find?

- The masses of the reactants would be equal to the masses of the product.

Why?

- This is due to the law of conservation of matter which states that matter is neither created nor destroyed in an isolated system but converted from one form to the other.

How is this related to balancing your equations?

- This is why during balancing of equations, we must ensure that the number of atoms in the reactant side must be equal to the number of atoms in the product side.

Answer:

0.01 M

Explanation:

NaOH (sodium hydroxide) is a strong base, so it is completely dissociated into ions in aqueous solution:

NaOH ⇄ Na⁺ + OH⁻

So, we have OH⁻ ions in solution.

From the problem, we have the pH value. The pH is calculated as:

pH = -log [H⁺]

As NaOH is a base, we can also calculate the pOH:

pOH = -log [OH⁻]

Thus. we can use the relation between pH and pOH to calculate the pOH and then use it to calculate [OH⁻]:

pH + pOH = 14 ⇒ pOH = 14 - pH = 14 - 12.05 = 1.95

pOH = -log [OH⁻] ⇒ [OH⁻] = [tex]10^{-pOH}[/tex]= [tex]10^{1.95}[/tex]= 0.0112 M ≅ 0.01 M
