When 32.0 g of F₂ react with enough N₂, 39.86g of NF₃ are formed.

<h3>What is stoichiometry?</h3>

Stoichiometry is the study of the quantitative relationships or ratios between two or more substances undergoing a physical change or chemical change.

Let's consider the following balanced equation.

N₂ + 3 F₂ ⇒ 2 NF₃

To calculate the mass of NF₃ formed from 32.0 g of F₂, we need to consider the following relationships.

The molar mass of F₂ is 38.00 g/mol.
The molar ratio of F₂ to NF₃ is 3:2.
The molar mass of NF₃ is 71.00 g/mol.

$32.00gF_2 \frac{1molF_2}{38.00gF_2} \frac{2molNF_3}{3molF_2} \frac{71.00gNF_3}{1molNF_3} = 39.86gNF_3$

When 32.0 g of F₂ react with enough N₂, 39.86g of NF₃ are formed.

Two substances with empirical formula HNO are hyponitrous acid (M = 62.04 g/mol) and nitroxyl (M = 31.02 g/mol).(c) Predict the

Levart [38]

While Nitroxyl, or HNO, has a dihedral form and just one nitrogen, Hyponitrous Acid, N2(OH)2, has both cis and trans structures and contains two nitrogens.

Hyponitrous acid has the chemical formula H2N2O2 or HON=NOH. 62.028 g/mol is the molecular weight of it. Additionally, it can take either a trans or cis form. When dry, the trans-hyponitrous acid crystallizes into white, explosive particles. Recent research has focused on nitroxyl (HNO), the one-electron reduced and protonated congener of nitric oxide (NO), as a potential drug for the treatment of heart failure and as a pre-conditioning agent to prevent ischemia-reperfusion injury, among other potential uses.

What happens as a result of photoelectric effect

natka813 [3]

Electrons are emitted from the surface of a metal in photoelectric effect.

<h3>What is the photoelectric effect?</h3>

The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..

For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.

Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

0.10 M potassium chromate is slowly added to a solution containing 0.20 M AgNO3 and 0.20 M Ba(NO3)2. What is the Ag+ concentrati

erastova [34]

Answer:

$[Ag^{+}]=4.2\times 10^{-2}M$

Explanation:

Given:

[AgNO3] = 0.20 M

Ba(NO3)2 = 0.20 M

[K2CrO4] = 0.10 M

Ksp of Ag2CrO4 = 1.1 x 10^-12

Ksp of BaCrO4 = 1.1 x 10^-10

$BaCrO_4 (s)\leftrightharpoons Ba^{2+}(aq)\;+\;CrO_{4}^{2-}(aq)$

$Ksp=[Ba^{2+}][CrO_{4}^{2-}]$

$1.2\times 10^{-10}=(0.20)[CrO_{4}^{2-}]$

$[CrO_{4}^{2-}]=\frac{1.2\times 10^{-10}}{(0.20)}= 6.0\times 10^{-10}$

Now,

$Ag_{2}CrO_4(s) \leftrightharpoons 2Ag^{+}(aq)\;+\;CrO_{4}^{2-}(aq)$

$Ksp=[Ag^{+}]^{2}[CrO_{4}^{2-}]$

$1.1\times 10^{-12}=[Ag^{+}]^{2}](6.0\times 10^{-10})$

$[Ag^{+}]^{2}]=\frac{1.1\times 10^{-12}}{(6.0\times 10^{-10})}= 1.8\times 10^{-3}$

$[Ag^{+}]=\sqrt{1.8\times 10^{-3}}=4.2\times 10^{-2}M$

So, BaCrO4 will start precipitating when [Ag+] is 4.2 x 1.2^-2 M

Negative radical in the periodic table

yKpoI14uk [10]

Answer:

A radical is a group of atoms of elements carrying a charge, e.g., chlorate [ClO3–]. Radicals or ions are formed by losing or gaining electrons. When an electron is gained the group of atoms acquire a negative charge and is called a negative radical or negative ion.
