2NH₂ + O₂ → N₂ + 2H₂O

<u>Explanation:</u>

Balancing the equation means, the number of atoms on both sides of the equation must be the same.

In the case of the given equation, we have to find out whether it is balanced or not.

2NH₂ + O₂ →  N₂ + 2H₂O

Atoms       Number of atoms before balancing     after balancing

                 LHS                 RHS                                    LHS         RHS

N               1                        2                                            2              2

H               2                       2                                            4              4                        

O               2                       1                                            2                2

To balance the N atoms, we have to put 2 in front of NH₂, and then to balance the H, O atoms, we have to put 2 in front of H₂O, so that each atom in left hand as well as right hand side of the equation was balanced.

if the complex has a formula of [m(h2o)6]3 , what effect will replacing the 6 aqua ligands with 6 cl− ligands have on δ ?
Eduardwww [97]

When we replace neutral ligands with negative ligands then the value of C.Δ will decrease.

In coordination chemistry, a ligand is an ion or molecule that binds to a significant steel atom to shape coordination complicated. The bonding with the metal generally includes a formal donation of 1 or more of the ligand's electron pairs regularly through Lewis Bases.

A ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. whilst a ligand binds to its respective receptor, the shape and/or interest of the ligand is altered to provoke several special styles of cellular responses.

Kat is investigating a compound and sees that it has even stronger hydrogen bonds than water. What can kat conclude is most like
Sidana [21]

Answer:

It is higher than that of water

Explanation:

Because we now know that through experimentation, the new compound has a higher and stronger hydrogen bonds than water, the specific heat capacity will be higher.

Specific heat capacity is the amount of heat needed to raise the temperature of a unit mass of as substance by 1°C.

  • This property is a physical property of matter .
  • Most physical properties are a function of intermolecular forces in a compound.
  • Since hydrogen bond is a very strong intermolecular force, the specific heat capacity will be stronger for the compound discovered.
  • This implies that it will require more heat to raise the temperature of a unit mass of this compound by 1°C.

Determine the specific heat of a 70 g sample of material that absorbed 96 J as it was heated from 293 K to 313 K
Damm [24]

This problem is providing us with the mass (70 g), absorbed heat (96 J) and initial and final temperatures (293 K and 313 K, respectively) so the specific heat of the material is required and found to be 0.0686 J/(g*K) as shown below:

<h3>Calorimetry:</h3>

In chemistry, we can go over calorimetry by writing the following relationship among heat, mass, specific heat and temperature change:

Q=mC(T_f-T_i)

Thus, one can get the specific heat by solving for C in the previous equation:

C=\frac{Q}{m(T_f-T_i)}

Hence, we can plug in the given data to obtain:

C=\frac{96J}{70g(313K-293K)}\\ \\C=0.0686\frac{J}{g*K}

Complete combustion of 2.0 metric tons of coal to gaseous carbon dioxide releases 6.6X10¹⁰ J of heat. Convert this energy to
Taya2010 [7]

First of all we should know that, 1 Joule = 0.000239 kilocalories.

So, 6.6×10^{10} J = 6.6×10^{10} × 0.000239 kilocalories

      6.6×10^{10} J = 15774000 kilocalories

                       = 1.58 × 10^{7} kilocalories

One joule is described as the quantity of electricity exerted when a pressure of 1 newton is implemented over a displacement of 1 meter. Within the SI machine, the unit of labor or electricity is the Joule.

The kilocalorie, or meals calorie, is the quantity of warmth required to elevate one kilogram of water 1 °C. warmness capability is the amount of heat required to raise one gram of material 1 °C beneath steady pressure. A kilocalorie is the amount of warmth required to raise the temperature of 1 kilogram of water one diploma Celsius.
