Answer:
Percent error = 2.8
Explanation:
Given data;
Actual value = 17.9 cm
Measured value = 17.4 cm
Percent error = ?
Solution:
Formula:
Percent error = [actual value - measured value / actual value] × 100
Now we will put the values in formula:
Percent error = [17.9 cm - 17.4 cm / 17.9 cm] × 100
Percent error = [0.5 cm /17.9 cm] × 100
Percent error = 0.028 × 100
Percent error = 2.8
There is only one carbon on the reactant side.
Answer:
Explanation:
If by speed ,you mean the rate at which they collide with each other then yes the answer would be
By decreasing the temperature
Since we already know thattemperature is the average kinetic energy of the molecules and increasing temperature will increase the motion of the solvent molecules and an decrease in temperature will decrease in the motion of solvent molecules
Cause (a substance) to be deposited in solid form from a solution.
Answer:
Keq = [NO₂]²/[N₂O₄] = 0.2.
Explanation:
- For the gas mixture equilibrium:
<em>N₂O₄ ⇄ 2NO₂</em>
The expression of the equilibrium constant (Keq):
Keq = [NO₂]²/[N₂O₄]
<em>∴ Keq = [NO₂]²/[N₂O₄]</em> = (0.03)²/(0.0045) = <em>0.2.</em>
