B the anwser is the one question is that it
Answer:
false
Explanation:
metal such as copper, silver, etc conducts heat and electricity. an object such as a rock, plastic, paper does NOT conduct heat.
<span>2 C</span>₆<span>H</span>₆ <span> + 15 O</span>₂<span> → 12 CO</span>₂<span> + 6 H</span>₂<span>O
if mass of CO</span>₂ = 130g
since moles = mass ÷ molar mass
then moles of CO₂ = 130 g ÷ ((12 × 1) + (16 × 2))
= 2.9545 mol
Mole ratio of CO₂ : O₂ is 12 : 15
∴ if mole of CO₂ = 2.9545 mol
then moles of O₂ = (2.9545 ÷ 12) × 15
= 3.6931 mol
∴ the answer is Option C
The solution would be like this for this specific problem:
<span>Given:
H2 = </span><span>2.6 atm
CL2 = 3.14 atm</span>
<span>
pressure H2 = 2.6 - x
pressure Cl2 = 3.14 - x
<span>pressure HBr = 2x = 1.13
x = 1.13 / 2 = 0.565
<span>pressure H2 = 2.6 - 0.565 = 2.035
pressure Br2 = 3.14 - 0.565 = 2.575
Kp = (1.13)^2 / 2.035 x 2.575</span></span></span>
= 1.2769 / (5.240125)
= 0.24367739319195629875241525726963
= 0.244
<span>Therefore, the Kp for the reaction at the given temperature
is 0.244.
To add, </span>the hypothetical pressure of a gas if
it alone occupied the whole volume of the original mixture at the same
temperature is called the partial pressure or Kp.
