<u><em>Answer:</em></u>
- Kc = [CH3OH] ÷ [CO][H2]∧2
<u><em>Explanation:</em></u>
CO(g) + 2H(2)(g) <-----> CH(3)OH(g)
- Rate of forward reaction = Kf [CO][H2]∧2
- Rate of reverse reaction = Kr [CH3OH]
At equlibrium
Rate of forward = rate of reverse
Kf [CO][H2]∧2 = Kr [CH3OH]
Kf/Kr = [CH3OH] ÷ [CO][H2]∧2
Kc = [CH3OH] ÷ [CO][H2]∧2
An electric field travels away from a <u>positive charge</u> and toward a <u>negative charge</u>.
<h3>
What is electric field?</h3>
Electric field is the region of space where the impact of electric force is felt.
The electrostatic field is always directed away from positive charges and toward negative charges, and, field lines must go away from positive charges and toward negative ones.
Thus, an electric field travels away from a positive charge and toward a negative charge.

Answer:
MOLARITY = 0.9554 mol/dm3
Explanation:
525 grams of SnF2 in 3.50 L of wate
To obtain the molarity, calculate the concentration in g/dm3 and then concentration in mol/dm3
Concentration in g/dm3 = 525 g/ 3.50 L
= 525g/ 3.50 dm3
= 150g/dm3 of SnF4
Concnetration in mol/dm3
concentration in mol/dm3 = concentration in g/dm3 / Relative molecular mass of SnF2
RMM of SnF2 = ( 119 + 19*2) = 157 g/mol
= 150g/dm3 / 157g/mol
= 0.9554 mol/dm3 of solution.
The molarity of the solution is therefore 0.9554mol/dm3
Answer:
Explanation:
You have the equation. Now change the 3.4 g H2 to moles. moles = grams/molar mass
<em>3.4 g/2.016 = 1.686 moles.</em>
Now using the coefficients in the balanced equation, convert moles H2O2 to moles H2O.
1.686 moles H2 x (2 moles H2O/2 moles H2O2) = 1.686 x (2/2) = 1.686 x (1/1) = 1.686 moles H2O.
Now you know that 1 mole of water is composed of 6.022 x 10^23 molecules. So
1.686 moles H2O x (6.022 x 10^23 molecules H2O/1 mole H2O) = ?? molecules.
