Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.
Now, Boyle's Equation: P₁V₁ = P₂V₂
V₂ = P₁V₁ ÷ P₂
∴ V₂ = (12.5L × 42.0 cm · Hg) ÷ 75 cm · Hg
⇒ V₂ = 7 L
Thus, the <span>volume when the pressure has increased to 75.0 cm Hg is 7 Litres.</span>
Answer:
Molarity of stock HCl solution is 0.89 M
Explanation:
The given problem can be solved using laws of dilution.
According to laws of dilution-
Where, and are initial and final concentration of a solution
and are initial and final volume of a solution
Here, , and
So, = = 0.89 M
Hence, molarity of stock HCl solution is 0.89 M
Answer:
17g
Explanation:
4NH3 (g) + 502 (g) –> 4NO (g) + 6H20 (g)
Mass of O2 mole = 32g
Therefore 5O2 = 160g
Mass of NH3 mole = 17g
Therefore 4NH3 = 17 x 4 =68g
Required amount of NH3 = 68 x 40/160 = 17g
it is called an element sir.
Answer:
Explanation:
The new product is a compound which is a product of combination of two reactants. This form of reaction is called Synthesis or combination. It involves the formation of compounds from the union of constituent elements in a reaction.
A compound is composed of two or more kinds of elements that are joined together in a definite grouping.
