Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.

Given chemical reaction is:

BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄

Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.

Hence the required coefficients is 1.

A solution is made by dissolving 15.5 grams of glucose (C6H12O6) in 245 grams of water. What is the freezing point depression of
sergij07 [2.7K]
From the equation; ΔTf = Kf × m
Where, Kf for water = 1.853 K kg/mole; m is the molarity = number of solute/amount of solvent in kg.
Glucose is the solute whose molecular mass is 180 g/mole and water is the solvent. 
Moles of solute = 15.5/180 = 0.0861 moles
Amount of solvent in kg = 245/1000 = 0.245 Kg
Therefore; molarity = 0.0861/0.245 = 0.3515 moles/Kg
Therefore; ΔTf = 1.853 × 0.3515 = 0.6513 K
Hence; the depression in freezing point is 0.6513 
The freezing point of solution will therefore be;
= 273 - 0.6513 = 272.3487 K

If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature? (2005 K)
jolli1 [7]

Answer:

205K

Explanation:

The following were obtained from the question:

n = 4moles

P = 5.6atm

V = 12L

R = 0.082atm.L/Kmol

T =?

PV = nRT

T = PV/nR

T = (5.6 x 12)/ (4 x 0.082)

T = 205K

Balance <br><br> _Mg + _HCL = _MgCl2 + H2
Pavel [41]
_Mg + _HCL = _MgCl2 + H2
Separate the terms on each side: 

_Mg + _HCl = _MgCl2 + H2

Mg- 1                 Mg-1
               
H-1                    H-2

Cl-1                    Cl-2

Mg is balanced on both sides so move on to the next (put a 1 in the space). 

1Mg

There are two H's and two Cl's on the results side, so to balance the equation put a 2 as a coefficient for HCl and it'll all balance out.

2HCl

Balamced equation will be: 

 1Mg + 2HCL = 1MgCl2 + H2

The chemical equations in model 1 contain the phase notations (s), (l), (g), and (aq). match each symbol with its meaning.
Sever21 [200]

Reaction equations contains symbols which show the physical state of the reactants and products.

<h3>What is a chemical equation:</h3>

A chemical equation is an expression that shows the interaction of reactants to yield products. Usually, symbols such as (s), (l), (g), and (aq) are used to show the state of the reactants and products.

The following are the respective meanings of these symbols;

  • (s) - solid
  • (l) - Liquid
  • (g) - gas
  • (aq) - dissolved in water
