Answer:

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

Explanation:

Equation of reaction:  4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)

From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas

1 mole of a gas at STP occupies a volume of 22.4 L

5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L

4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L

Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

Answer:

Physical matter is made up of atoms and molecules. An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.

Answer:Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon, the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, altho…

Answer:

Cl has 7 dots

if its Cl2; Cl-Cl it will contain 14 dots

Explanation:

The electron-dot formula of the chlorine molecule Cl₂is shown in the attached diagram below.

A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.

Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.

As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.

First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.

As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

To solve this we must know the concept behind the phenomenon of elevation in boiling point when a non volatile solute is added to any solvent. Therefore, boiling point in °C of a 0.527 m aqueous solution of LiBr is  100.54 °C.

Whenever a non volatile solute is added to a solvent then the boiling point of solvent increases.

Mathematically,

ΔT= Kb× molality

The complete balanced equation can be written as

LiBr → Li⁺ + Br⁻ [two ions]

substituting all the given values in the above mathematical expression, we get

(0.527 m LiBr) x (2 mol ions / 1 mol LiBr) = 1.054 m ions

(0.512 °C/m) x (1.054 m) = 0.540 °C change

100.00°C + 0.540 °C = 100.54 °C

Therefore, boiling point in °C of a 0.527 m aqueous solution of LiBr is  100.54 °C.

Answer:

i think option b

C 1 and 3

Explanation:

Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.

Crystals grow because salt molecules in the solution meet up and interlock. As they do so, they fit together like puzzle pieces, arranging themselves in a lattice structure, thus creating a crystal nucleus. ... it crystallizes.

Answer:

The amount of solar radiation emitted by the Sun varies during different Earth seasons

Explanation:

Answer:

The answer is "-10° C".

Explanation:

Fahrenheit and Celsius, both use scales for measuring their temperature standard. The Fahrenheit suggests, as just a cold water point by taking 32° F and hot water rate by taking 212° F. The freezing temperature of both the water at the Celsius scale is 0° C, as well as the boiling point of its water at 100° C.

Converting the Fahrenheit  to Celsius:

Formula: [tex]\bold{^{\circ}F = ^{\circ}C \times 1.8 + 32}[/tex]

°F= 14

[tex]\to 14 = ^{\circ}C \times 1.8 + 32}\\\\\to 14 -32 = ^{\circ}C \times 1.8 \\\\\to -18 = ^{\circ}C \times 1.8 \\\\\to ^{\circ}C = \frac{-18}{1.8} \\\\\to ^{\circ}C = \frac{-180}{18} \\\\\to ^{\circ}C = - 10[/tex]
