Answer:
the answer is V=0.0306878
The balanced equation for the above reaction is as follows;
<span>Fe</span>₂<span>O</span>₃<span> + 3 CO --> 2 Fe + 3 CO</span>₂
<span>stoichiometry of CO to Fe is 3:2
molar volume states that 1 mol of any gas occupies a volume of 22.4 L
If 22.4 L contains 1 mol of CO
Then 3.65 L contains - 1/22.4 x 3.65 = 0.16 mol
3 mol of CO forms 2 mol of Fe
Then 0.16 mol of CO forms - 2/3 x 0.16 = 0.1067 mol of Fe
Therefore mass of Fe produced - 0.1067 mol x 55.8 g/mol = 5.95 g</span>
Answer:
A
Explanation:
ethane weaker than ethyne because it is not as unsaturated as ethyne
Ethene is longer because it need to bond with two more hydrogen atom
Answer:
pH = 6.964 which rounds to 7.0 if 2 sig figs
Explanation:
Ka₁ * Ka₂ = x
2.4x10⁻⁴ * 4.9x10⁻¹¹ = 1.176x10⁻¹⁴
√1.176x10⁻¹⁴ = 1.084435337x10⁻⁷
pH= -log[H⁺]
pH= -log[1.084435337x10⁻⁷]
pH= 6.964796339
<span>Good Morning!
Products that produce fatal vapors are called "toxins". Although corrosive, flammable and reactive substances also have the ability to cause death to humans. In this case, they are called toxic.
