What does balancing chemical equations mean?Reaction balancing is a method used in several areas of Chemistry to determine the amount of matter of each of the substances participating in the reaction, as well as to establish the existing proportions between the components.
Then the equation before performing the balancing is given by:
[tex]NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+H_2O+3CO_2[/tex]
For this equation to become balanced it will be necessary that:
On the right side of the equation we have more Na and H so it will be necessary to multiply by 3So the balanced equation will be:

A box shaped like a rectangular prism has a volume of 280 in^3
Based on the calculations, the width and height of this rectangular prism are 7 inches and 10 inches respectively.
How to calculate the volume of a rectangular prism?Mathematically, the volume of a rectangular prism can be calculated by using this formula:
V = L × W × H
Where:
L is the length.H is the height.W is the width.Given the following data:
Length = 4 in.
Width = (n + 2) in.
Height = (n + 5) in.
Substituting the given parameters into the formula, we have;
280 = 4 × (n + 2) × (n + 5)
280 = 4 × (n² + 7n + 10)
60 = n² + 7n + 10
n² + 7n - 60 = 0
(n - 5)(n + 12) = 0
Therefore, n = 5 or -12.
For the width, we have:
Width = n + 2
Width = 5 + 2
Width = 7 in.
For the height, we have:
Height = n + 5
Height = 5 + 5
Height = 10 in.

The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle
Answer:
Explanation:
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

How many grams of calcium oxide will be produced in a closed vessel containing 20.0 kg of calcium and 20.0 kg of oxygen gas if the reaction goes to completion? (atomic mass of calcium = 40.1 amu)
Answer:
Explanation:
The mass of Calcium oxide that will be produced in a closed vessel is 27984.1311 g. The Number of moles is defined as given mass over molar mass.
Calculation of Number of moles:
Number of moles = Given mass / Molar mass
For Calcium :-
Mass of calcium = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of calcium = 40.078 g/mol
Thus,
Number of moles = 20000 g / 40.078 g/mol
Number of moles = 499.02 moles
For oxygen gas :-
Mass of oxygen gas = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of oxygen gas = 31.999 g/mol
Thus,
Number of moles = 20000 g / 31.999
Number of moles = 625.19 moles
According to the given reaction:
2 moles of calcium reacts with 1 mole of oxygen gas
Also,
1 mole of calcium reacts with 1/2 mole of oxygen gas
So,
499.0269 mole of calcium react with mole of oxygen gas
Moles of oxygen gas = 249.5135 moles
Available moles of oxygen gas = 625.0195 moles
Limiting reagent is the one which is present in small amounts. Thus, calcium is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
2 moles of calcium produces 2 moles of calcium oxide
So,
1 mole of calcium produces 1 mole of calcium oxide
Also,
499.0269 moles of calcium produces 499.0269 moles of calcium oxide
Moles of calcium oxide = 499.0269 moles
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = Moles × Molar mass = 499.0269 * 56.0774 g = 27984.1311 g
27984.1311 g of calcium oxide will be produced.

The exact value of the cosine of 11π / 12 will be given as negatice (1 + √3)/(2√2).
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The trigonometric expression is given below.
⇒ cos (11π/12)
We know that 11π/12 is equal to 165 degrees. Then we have
cos 165° = cos (45° + 120°)
We know that
cos (A + B) = cos A cos B - sin A sin B
Then we have
cos (45° + 120°) = cos 45° cos 120° - sin 45° sin 120°
cos (45° + 120°) = 1/√2 x (- 1/2) - 1/√2 x √3/2
cos (45° + 120°) = - (1 + √3)/(2√2)
