Balance the following chemical equation.​​​​​​​(2)

Chemistry
1 answer:
Angelina_Jolie [31]3 years ago
8 0

Balanced chemical equation:

2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

Explanation:

The correct chemical reaction is:

C₃H₆N₆ (l) + O₂ (g) → CO₂ (g) + H₂O (g) + N₂ (g)

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

Balanced chemical reaction:

C₃H₆N₆ (l) + (9/2) O₂ (g) → 3 CO₂ (g) + 3 H₂O (g) + 3 N₂ (g)

To have integer numbers we multiply the equation with 2 to obtain:

2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

You note that cells placed in a solution crenate. What could you definitively conclude about the solution?
lys-0071 [83]

Answer:it means the cell is an hypertonic or high concentration solution

Explanation: osmosis is defined as movement of water from a region of high concentration to a region of low concentration of water.

Now being in a hypertonic solution means the sorrounding solution in a high concentration of the solute which means water is in low in concentration , so osmotic pressure move water from the cell (which has a relatively higher water concentration )to it's sorrounding which has a lower concentration of water, resulting in the shrinking or crenation of the cells.

CuCl2 + Al ---> AlCl3 + Cu
Ket [755]

For a balance chemical equation:

The number of atoms of a molecule should remain conserved that is total number of atom of a molecule in reactant side should equal to the number of atoms of a molecule in the product side.

Here also the number of atoms of an element should remain conserved on both sides, So the answer is option B.

That is

B) 3CuCl₂ + 2Al ---> 2AlCl₃ + 3Cu

Here the number of atoms of Cu, Cl and Al are equal in both side , reactant as well as product.

For which process is ΔS negative? Group of answer choices A. grinding a large crystal of KCl to powder B. raising the temperatur
ludmilkaskok [199]

Answer:

C.

Explanation:

The entropy (S) is the measure of the randomness of a system, and ΔS = Sfinal - Sinitial. As higher is the disorder of the system, as higher is the entropy.

A. When KCl is fractionated in power, there'll be more portions of it, so, the disorder must be higher, then ΔS is positive.

B. As higher is the temperature, higher is the kinetic energy of the system, and because of that, the disorder is also higher, so ΔS is positive.

C. The decrease in the volume (compression) decreases the distance between the molecules, so the system will be more organized, then ΔS is negative.

D. The volume before the mixing will be higher, and the ethanol will dissociate, so it will be more particles, the disorder will increase, and ΔS is positive.

E. Sgas > Sliquid > Ssolid because of the disorder of the molecules, then ΔS is positive.

The pressure is recorded as 738 mmHg.Convert this measurement to atmosphere (atm)
garri49 [273]
As we know that 760 mmHg is equal to 1 atm.

So,
If 760 mmHg is equal to   =   1 atm
Then
738 mmHg will be equal to   =   X atm

Solving for X,
                                X   =   (738 mmHg × 1 atm) ÷ 760 mmHg

                                X   =   0.971 atm

Result:
           738 mmHg
is equal to 0.971 atm.
