Consider the following reaction:
3 Br2 + 6 OH¹-5 Br¹ + BrO3¹ + 3 H₂O
If 4.68 moles of Br2 are reacted with 8.12 moles of OH¹, how many moles of Br
can be formed? (Report your answer to two places past the decimal point.
Moodle is looking for a number only, no units.)
Answer:
Explanation:
I'm assume that 3 Br2 + 6 OH¹-5 Br¹ + BrO3¹ + 3 H₂O is meant to read:
3 Br2 + 6 OH^-1 = 5 Br^-¹ + BrO3^-¹ + 3 H₂O
The balanced equation tells us that 3 moles of Br2 will react with 6 moles of OH^-1 to produce 5 moles of Br^-1.
The first step is to determine whether the Br2 or OH^-1 are limiting reagents. That is, is there enough of each to complete the reaction, with none left over.
We need 3 moles of Br2 for every 6 moles of OH^-1, a molar ratio of 1/2 (Br2/OH).
We are given 4.68 moles of Br2 and 8.12 moles of OH^-1. That is a ratio of 4.68/8.12 or 0.5764. This is higher than the ratio of 1/2 or 0.5 that is required. That means we have more than enough Br2. The limiting reagent is the OH^-1. Once it is consumed, the reaction stops and we are left with some unreacted Br2.
So we need the molar ratio of the OH^-1 to the Br from the balanced equation: We see that 6 moles of OH^-1 are required to produce 5 moles of Br, a 6/5 molar ratio.
Therefore, we may assume all 8.12 moles of the limiting reagent, OH^-1, will be consumed to produce *6/5) that amount of Br.
(8.12 moles OH^-1)*((6 moles Br)/(5 moles OH^-1)) = 9.75 moles of Br.
For curiosity's sake, we can determine the amount of unreacted Br2. 8.12 moles of OH^-1 would require (8.12 moles OH)*(1/2) = 4.06 moles of Br2.
4.68 moles starting Br2
4.06 moles consumed
0.62 moles remaining Br2

A solution containing 1 mol of a strong electrolyte will have a greater effect on the colligative properties of the solution than 1 mol of a nonelectrolyte. A strong electrolyte will dissociate or ionize in an aqueous solution, and therefore the total number of dissolved solute particles is greater for 1 mol of a strong electrolyte than for 1 mol of a nonelectrolyte solute.
How do electrolytes work?An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.
Types of electrolytes:-A substance is referred to as a strong electrolyte if the physical or chemical process that produces the ions is virtually 100% effective (all of the dissolved molecules give ions). Weak electrolytes are those in which only a very small portion of the dissolved substance goes through the ion-producing process.

Polonium-208 is an alpha emitter with a half-life of 2.90 years. How many milligrams of polonium from an original sample of 2.00 mg will remain after 8.00 years
Answer:
0.296 mg
Explanation:
8.00/2.90 half lives have passed, so this means the remaining mass is
[tex]2.00 {(0.5)}^{8.00 \div 2.90} [/tex]
which is about 0.296 mg.
The amount of polonium remaining after 8.00 years is 0.296 mg. This is obtained by using rate law of first order kinetics.
What is the rate law of first order kinetics and the half-life of the compound?The expression for the rate law for first order kinetics is
k = [tex]\frac{2.303}{t}log\frac{a}{a-x}[/tex] years⁻¹
Where,
k - rate constant
t - time passed by the sample
a - initial amount of the reactant
a-x - final amount of the reactant
The expression for the half-life of the compound is
[tex]t_{\frac{1}{2}}=\frac{0.693}{k}[/tex] years
Calculating the amount of polonium remained after 8.00 years:Given that,
A Polonium-208 is an alpha emitter with a half-life of 2.90 years.
I.e., [tex]t_{\frac{1}{2}}[/tex] = 2.90 years
Then,
2.90 = (0.693)/k
⇒ k = (0.693)/(2.90) = 0.2389 years⁻¹
Then,
for t = 8.00 years,
Since we have rate law of first order kinetics as
k = [tex]\frac{2.303}{t}log\frac{a}{a-x}[/tex]
⇒ k = (2.303/8.00) log(a/a-x)
Where the initial amount of the reactants is a = 2.00 mg
So,
k = 0.287 log (2.00/a-x) (a-x is the final amount of the reactants)
⇒ 0.238 = 0.287 log(2.00/a-x)
⇒ (0.238/0.287) = log(2.00/a-x)
⇒ 0.829 = log(2.00/a-x)
⇒ (2.00/a-x) = [tex]10^{0.829}[/tex] = 6.745
⇒ (a-x) = 2.00/6.745 = 0.296 mg
Therefore, the remaining polonium is 0.296 mg after 8.00 years.

How does a fire extinguisher works ?
Answer:
Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out. Some ways of using fire extinguisher are:
Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen. Dry powder extinguishers soak up heat, melt on the fuel, and cut off oxygen, but they also neutralize the fuel (cutting it off from the fire) .Explanation:

1. How many grams of sodium chloride is produced when 3.4 g of sodium reacts with 8.9 g of chlorine in
this balanced equation?
2Na+ Cl₂ → 2NaCl
The Answer to the question is 14 grams approximately.
Atomic mass of Na = 23 u
Given mass of Na = 3.4 gm
Moles of Na = given mass of Na / molar mass of Na
Moles of Na = 3.4 / 23 moles = 0.15 moles approximately
So, 0.15 moles of Na approximately
Molar mass of Cl₂ = 35.45 × 2 = 70.9 u
Given mass of Cl₂ = 8.9 gm
Moles of Cl₂ = given mass of Cl₂ / molar mass of Cl₂
Moles of Cl₂ = 8.9 / 70.9 moles = 0.12 moles approximately
So, 0.12 moles of Cl₂ approximately
Balanced chemical equation
2Na + Cl₂ → 2NaCl
Ratio of Moles to Stoichiometric coefficients
0.15/2 0.12/1
0.075 < 0.12
So, as ratio of Na is less then it will be our Limiting reagent.
Which means that Cl₂ will consume complete in the reaction.
It is clear from the reaction that 1 moles of Cl₂ are making 2 mole of NaCl
1 moles of Cl₂ → 2 mole of NaCl
0.12 moles of Cl₂ → 2 × 0.12 mole of NaCl
0.12 moles of Cl₂ → 0.24 mole of NaCl
So, 0.12 moles of Cl₂ will make 0.24 mole of NaCl
0.24 mole NaCl = mass formed NaCl / molar mass of NaCl
mass formed NaCl = 0.24 × molar mass of NaCl
mass formed NaCl = 0.24 × 58.44
mass formed NaCl = 0.24 × 58.44
mass formed NaCl = 14 grams (approximately)
14 grams of NaCl will be formed.
So, approximately 14 grams NaCl is formed from 3.4 grams of Na and 8.9 grams of Cl.

Photosynthesis reactions are the process that occurs in the plants to yield oxygen from food. In the process, 55 gm of carbon dioxide produces 40 gm of oxygen. Thus, option B is correct.
What is photosynthesis?Photosynthesis is a metabolic reaction that takes place in the plant cell where the sun energy converts the water and carbon dioxide into sugar (glucose) and oxygen.
The photosynthetic reaction is given as,
6H₂O + 6 CO₂ → C₃H₁₂O₆ + 6O₂
In the above reaction, there are 6 moles of carbon dioxide needed to produce 6 moles of oxygen. Hence, moles of carbon dioxide consumed = moles of oxygen produced.
Mass from moles is calculated as,
Moles = mass ÷ molar mass
Equating moles of both CO₂ and O₂,
mass ÷ molar mass = mass ÷ molar mass
55 ÷ 44 = m ÷ 32
m = 55 × 32 ÷ 44
= 40 gm
Therefore, 40 gm of oxygen is produced from 6 moles of carbon dioxide.

This chapter deals with chemical equilibrium, or how far chemical reactions proceed. Some reactions convert reactants to products with near 100% efficiency but others do not.
Chemical equilibrium is a dynamic process and occurs when the rates of two opposing processes (reactions) become the same. Unless conditions are somehow changed, the concentrations of both reactants and products remain constant after equilibrium is achieved.

Dipole interactions are susceptible interactions that get up from the close association of permanent or precipitated dipoles. Collectively these forces are called Van der Waals interactions. Proteins incorporate a massive number of these interactions, which vary substantially in energy.
Solubility depends on the solvent's capacity to overcome the intermolecular forces in a solid. Red blood cells have an excessive concentration of dissolved ions. When positioned into pure water they rupture.
Polar species are soluble in water, whilst nonpolar species are soluble in oils and fats. Covalent solubility uses the like dissolves like a rule.
