The balanced equation with the reaction-quotient expression is;

U(s) + 3F₂(g) → UF₆(g)

<h2>Further Explanation:</h2><h3>Chemical equations </h3>

Chemical equations are equations showing reactions between reactants to form products.
Chemical equations show the reactants or starting substances and products or substances formed during the reaction.

<h3>Law of conservation of mass </h3>

The law of conservation requires that when writing chemical equations, the mass of the reactants should be equal; to the mass of the products.
This is done by making sure the number of atoms of each element involved in the chemical equation is equal on both sides of the equation.

To ensure the law of conservation in chemical equations is observed we balance chemical equations.

<h3>Balancing chemical equation:</h3>

Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products.
Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reactions.
For example; the equation; U(s) + 3F₂(g) → UF₆(g) is balanced as the number of Uranium and Fluoride atoms are equal on both sides of the equation.

The equation presented above is that of uranium reacting with fluorine forming uranium fluoride.

The chemical reaction can be balanced by carefully studying the equation and balancing the number of atoms of each of the element in both sides of the chemical reaction. That is,

<em> U(s) + 3F₂(g) --> UF₆(g)</em>

What is the rate of acceleration of a 2,000-kilogram truck if a force of 4,200n is used to make it start moving forward?

butalik [34]

Answer:

The answer to your question is: a = 2.1 m/s²

Explanation:

Data

Acceleration : ?

Mass = 2000 kg

Force = 4200 N

Formula

Newton's second law of motion F = ma

a = F / m

Substitution

a = 4200 N / 2000 kg

a = 2.1 m/s²

Which reactants would lead to a spontaneous reaction?

balandron [24]

Answer: Option (b) is the correct answer.

Explanation:

The elements which have excess or deficiency of electrons will react readily.

Atomic number of Mn is 25 and electronic configuration of $Mn^{2+}$ is [Ar] $4s^{0}3d^{5}$ . This configuration is stable.

Atomic number of Cr is 24 and electronic configuration of $Cr$ is [Ar] $4s^{1}3d^{5}$ . This configuration is not stable.

Atomic number of Fe is 26 and electronic configuration of $Fe$ is [Ar] $4s^{2}3d^{6}$ . This configuration is stable.

Atomic number of Cu is 29 and electronic configuration of $Cu^{2+}$ is [Ar] $4s^{0}3d^{9}$ . This configuration is not stable.

Atomic number of Al is 13 and electronic configuration of Al is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{1}$ . This configuration is not stable.

Atomic number of Ba is 56 and electronic configuration of $Ba^{2+}$ is [Kr] $4d^{10}5s^{2}5p^{6}$ . This configuration is stable.

Atomic number of Mg is 12 and electronic configuration of $Mg^{2+}$ is $1s^{2}2s^{2}2p^{6}$ . This configuration is stable.

Atomic number of Sn is 50 and electronic configuration of Sn is [Kr] $4d^{10}5s^{2}5p^{2}$ . This configuration is stable.

Thus, we can conclude that out of the given options, only Fe and $Cu^{2+}$ reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.

How many moles of dipyrithione contain 6.3×1024 atoms of nitrogen?

chubhunter [2.5K]

Answer:

5.23 moles of C₁₀H₈N₂O₂S₂

Explanation:

In order to find the moles of dipyrithione we need to know its formula:

C₁₀H₈N₂O₂S₂

1 mol of N contains 6.02×10²³ atoms

We need to find out the moles of 6.3×10²⁴ atoms of N

6.3×10²⁴ atoms . 1 mol /6.02×10²³ atoms = 10.4 moles of N

Therefore, we know that 1 mol of dipyrithione has 2 moles of N, so we need to make this rule of three:

2 moles of N are contained in 1 mol of C₁₀H₈N₂O₂S₂

10.4 moles of N must be contained in (10.4 . 1) /2 = 5.23 moles of C₁₀H₈N₂O₂S₂
