Explanation:
A reversible reaction is a reaction which results in the formation of products which gives back reactants. Therefore, it is said that a reversible reaction occurs in both forward and backward direction.
Thus, it can be concluded that a reversible reaction is a reaction that takes place in the both directions . If the reaction were to equilibrium, the rate of the forward reaction would equal that of the reverse reaction.equilibrium.
4. an individual form of life
The amount of heat, H, needed to boil off certain mass, m, of the substance is given by the equation,
H = mHv
where Hv is the heat of vaporization. Manipulating the equation, the mass is calculated by,
m = H/Hv
Substituting the known values,
m = 15000 J/(850 J/g) = 17.65 g
Thus, the mass of ethyl alcohol is approximately 17.65 g.
Answer:
<u>136.67 g of Na3PO4 i</u>s required to create 100 gram of NaOH.
Explanation:
The balanced equation:
1 mole Na3PO4 = 164 g/mole (Molar mass)
1 mole NaOH = 40 g/mole (Molar mass)
Now,
1 mole of Na3PO4 produce = 3 mole of NaOH
164 g/mol of Na3PO4 produce = 3(40) g/mol of NaOH
or
120 g/mol of NaOH is produced from = 164 g/mol of Na3PO4
1 g/mol of NaOH is produced from =
100 grams of NaOH is produced from =
gram of Na3PO4
calculate,
= 136.67 g
The total pressure of gases is equivalent to 739mmH divided by the area.
<h3>How to calculate the total pressure of gases?</h3>
To calculate the total pressure of gases, the next formula can be used:
- Total pressure: Force/area
- Total pressure 739 mmH/area
<h3>How to calculate the area?</h3>
The area of a cylinder is equal to 2πrh+2πr².
You can know the radio by checking the measurement of the base of the graduated cylinder. Also, you can determine the height by observing how many mm the gas is occupying. Then follow these steps:
- Find out the area based on the formula provided.
- Replace the area in the pressure formula.
- Solve the formula.
Note: This question is incomplete because the height occupied by the gas and the radio of the cylinder are not provided. Due to this, I answered this question based on general knowledge.
