Answer:
The answer to your question is: 2.75 x 10 ²¹ atoms
Explanation:
Data
H₃PO₄
mass = 0.1488 g
MW H₃PO₄ = 3 + 31 + (16 x 4) = 98g
98 g of H₃PO₄ ------------------ 3 g of H₂
0.1488 g H₃PO₄ --------------- x
x = 0.0046 g of H₂
1 g of H₂ ------------------- 6.023 x 10²³ atoms
0.0046 g of H₂ -------------- x
x = (0.0046 x 6.023 x 10²³) / 1
x = 2.75 x 10 ²¹ atoms
<u>Answer:</u> The chemical formula of the compound formed is
<u>Explanation:</u>
Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.
Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.
We are given:
An anion having chemical formula named as sulfate ion
This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.
Hence, the chemical formula of the compound formed is
Mineral resource : It is the source of any material in earth's crust. The source from which there is opportunity of extraction of the material.
Mineral reserve : The mineral resource from which a material can be extracted by means of economic techniques. The ores of metals are generally considered to be mineral reserve.
Explanation:
There are several ways to define acids and bases, but pH and pOH refer to hydrogen ion concentration and hydroxide ion concentration, respectively. The "p" in pH and pOH stands for "negative logarithm of" and is used to make it easier to work with extremely large or small values. pH and pOH are only meaningful when applied to aqueous (water-based) solutions. When water dissociates it yields a hydrogen ion and a hydroxide.
<u>Answer:</u> The equilibrium constant for the given reaction is 0.8
<u>Explanation:</u>
Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as
For the general equation:
The equilibrium constant is represented as:
For the given chemical equation:
for this equation is given by:
Concentration at equilibrium of
Putting values in above equation, we get:
Hence, the equilibrium constant for the given chemical reaction is 0.8
