Due to time constraint, I am only able to help you balance the equation.

BALANCED EQUATION ANSWER:

1 NH3(g) + 3 O2(g) --> 1 NO(g) + 3 H2O

N 1 N 1

H 3 H 1 x 3 = 3

O 2 x 3 = 6 O 2 x 3 = 6

Explanation:

In order to balance it out, the amount of each element must match. To do this, you have to multiply specific elements to match the other. As you can see, Nitrogen was already balanced, but the others were not.

If there is any further confusion, feel free to message me! :)

How many electrons in an atom can have each of the following quantum number or sublevel designations?

storchak [24]

10 electrons in an atom can have each of the 3d quantum number or sublevel designations.

<h3>What are four quantum numbers?</h3>

Quantum numbers are used to characterize the values of conserved quantities in a quantum system's dynamics in both quantum physics and chemistry.

1) The "n" sign refers to the principal quantum number. It shows how many shells there are.

2) The "l" sign indicates the azimuthal quantum number. It gives the form of the orbitals and their angular momentum. 0 to n-1 make up its range.

3) " $m_{l}$ " stands for the magnetic quantum number. It serves as a cue for spatial orientation. The range of it is -l to +l.

4) Spin quantum number, represented by the symbol " $m_{s}$ ". It shows how the electron is spinning.

Give the following for SO2 and BrF5:

frosja888 [35]

Answer:

The given molecules are SO2 and BrF5.

Explanation:

Consider the molecule SO2:

The central atom is S.

The number of domains on S in this molecule is three.

Domain geometry is trigonal planar.

But there is a lone pair on the central atom.

So, according to VSEPR theory,

the molecular geometry becomes bent or V-shape.

Hybridization on the central atom is

$sp^{2}$ .

Consider the molecule BrF5:

The central atom is Br.

The number of domains on the central atom is six.

Domain geometry is octahedral.

But the central atom has a lone pair of electrons.

So, the molecular geometry becomes square pyramidal.

The hybridization of the central atom is $sp^{3} d^{2}$ .

The shapes of SO2 and BrF5 are shown below:

When 0.5141 g of biphenyl (C12H10) undergoes combustion in a bomb calorimeter, the temperature rises from 25.823 °C to 29.419 °C

natka813 [3]

Answer:

$\Delta_{r}U$ of the reaction is -6313 kJ/mol

$\Delta_{r}H$ of the reaction is -6312 kJ/mol

Explanation:

$Temperature\,\,change= \Delta U = 29.419-25.823 =3.506^{o}C$

$q_{cal}= C \times \Delta T$

$=5.861 \times 3.596 = 21.076\,kJ$

$q_{rxn}= -q_{cal}= -21.076\,kJ$

$\Delta_{r}U= -21.076 \times \frac{154}{0.5141}= -6313\, kJ/mol$

Therefore, $\Delta_{r}U$ of the reaction is -6313 kJ/mol.

The chemical reaction in bomb calorimeter is as follows.

$C_{12}H_{10}(s)+\frac{27}{2}O_{2}(g)\rightarrow 12CO_{2}(g)+5H_{2}O(g)$

$Number\,of\,moles\Delta n=(12+5)-\frac{27}{2}=3.5$

$\Delta_{r}H=\Delta E+ \Delta n. RT$

$=-6313+3.5\times 8.314\times 10^{-3} \times 3.596=-6312\,kJ/mol$

Therefore, $\Delta_{r}H$ of the reaction is -6312 kJ/mol.

A solid was found to be highly soluble in water. Treating separate portions of a solution of this solid with aqueous solutions o

chubhunter [2.5K]

Answer:

c. $Li_2CO_3$

Explanation:

Hello,

Due to the fact that an odorless gas was released, the chemical reaction between lithium carbonate and a random acid (for instance hydrochloric acid) turns out into:

$Li_2CO_3(s)+2HCl(aq)-->2LiCl(aq)+CO_2(g)+H_2O(l)$

It is known that carbonic acid is unstable and it quickly decomposes into water and carbon dioxide which is an odorless gas. In spite of the fact that the $PbSO_3$ releases $SO_2$ it isn't the solid since that gas is odorous.

Best regards.
