Answer:
A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. A compound is not a pure substance because it is not an element, and only elements are pure substances.
Answer:
The value of Kp for the system = 0.0128 atm
Explanation:
Let, the gaseous substance is SO₂Cl₂
SO₂Cl₂ ⇄ SO₂ + Cl₂
Initially x 0 0
At equilibrium (x - 14.5%x) 14.5%x 14.5%x
= 85.5 % x
Total moles of gases at equilibrium
= 85.5 % x + 14.5%x + 14.5%x
= 114.5 % x
Partial pressure of SO₂ () =
Partial pressure of Cl₂
Partial pressure of SO₂Cl₂
So,
Answer:
32km/hr
Explanation:
The question asks to calculate the average speed for a boat.
Mathematically, the average speed is the total distance divided by the total time
Let’s get the total distance traveled:
That would be 70km + 26km = 96km
Now the total time taken would be 3 as the boat did not move at all for an hour.
The average speed is thus 96/3 = 32km/hr
C. it means aqueous, and we all know what aqua means (I hope)
