Since a parallelogram is defined as a quadrilateral with two pairs of parallel sides, Emily drew in a diagonal of a parallelogra
koban [17]

Explanation:

In the attachment fig ABCD is a parallelogram with AC as diagonal.

we know that,

In  a parallelogram opposite sides are equal and parallel

In a parallelogram sum of adjacent angles is 180°

that is

∠A+∠D= ∠B+∠C= 180°

Also, in  a parallelogram opposite angles are equal.

So in ΔADC and ΔABC

1) AD=BC

2) DC= AB

And

3) ∠ADC= ∠ABC

therefore, ΔADC and ΔABC are congruent to each other and Emily was right.

When adding or subtracting deelmals, how many digits should the answer contain?
Alexus [3.1K]

Answer:

Depends, but in most cases, 2.

It's best to use as many digits as possible to keep it accurate.

Explanation:

This varies between teachers, as most schools go with 2 decimal places.

This is something that depends in your situation.

You technically want as many decimals as possible to keep it as accurate, but most people stick with 2.

I personally do 3, and commonly do 5 sometimes.

What change would shift the equilibrium system to the left?
SVEN [57.7K]

Answer:

Adding more of gas C to the system

Explanation:

  • <em>Le Châtelier's principle</em><em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

1) Adding more of gas C to the system:

Adding more C gas will increase the concentration of the products side. So, the reaction will be shifted to the left to attain the equilibrium again.

2) Heating the system:

Heating the system will increase the concentration of the reactants side as the reaction is endothermic. so, the reaction will be shifted to the right to attain the equilibrium again.

3) Increasing the volume:

has no effect since the no. of moles of gases is the same in both reactants and products sides.

4) Removing some of gas C from the system:

Removing some of gas C from the system will decrease the concentration of the products side. So, the reaction will be shifted to the right to attain the equilibrium again.

<em>So, the right choice is: Adding more of gas C to the system.</em>

<em></em>
