Equilibrium describes the balance that results from a forward and reverse reaction proceeding at equal rates. Since reaction rat

Delvig [45]

Answer:

b) the reaction proceeds to a new equilibrium in the direction that offsets the change.

Explanation:

According to Le Chatelier's principle, when a system experiences a constraint such as a change in pressure, temperature or concentration, the system will readjust itself in order to annul the constraint.

This simply means that when temperature, concentration or pressure is changed, a new equilibrium position is reached in order to offset the changes in the system.

a square boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. it has a mass of 213 g. water has a density

Stolb23 [73]

Density of boat = $\frac{MASS}{VOLUME}$

= $\frac{213 g}{(2 cm * 11 cm * 11cm)}$

= 0.88 g / cm³

Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means, the boat will NOT sink.

Cassie buys a rope at the store. The label on the package says that the rope is 3.15 meters in length. She measures the rope as

satela [25.4K]

Answer:

Percent error = 41%

Explanation:

Percent error:

Percent error is the difference between the measured value and actual value divided by actual value multiply by 100.

Given data:

Actual length of rope = 3.15 m

Measured length of rope = 1.85 m

Percent error = ?

Solution:

Formula:

Percent error = [measured value - actual value / actual value ] × 100

Now we will put the values in formula.

Percent error = [1.85 - 3.15 / 3.15 ] × 100

Percent error = [-1.3 /3.15 ] × 100

Percent error = -0.41 × 100

Percent error = 41%

The negative sign shows that measured value is less than the actual value but often results are reported in absolute value.
