how many grams of F2 are needed to react with 3.50 grams of Cl2 Equation needed for question- Cl2+3F2--&gt;2ClF3 please explain
pshichka [43]

Answer:

5.62 g of F2

Explanation:

We have to start with the chemical reaction:

Cl_2~+~3F_2~-->~2ClF_3

<u>We have a balanced reaction</u>, so we can continue with the <u>mol calculation</u>. For this, we need to know the <u>molar mass</u> of Cl_2  (70.906 g/mol), so:

3.5~&#10;g~Cl_2&#10;\frac{1~mol~Cl_2}{70.906~g~Cl_2}=0.049~mol~Cl_2

Now, with the <u>molar ratio</u> between Cl_2  and F_2  we can convert from moles of Cl_2  and F_2  (1:3), so:

0.049~mol~Cl_2\frac{3~mol~F_2}{1~mol~Cl_2}=0.148~mol~F_2

Finally, with the <u>molar mass</u> of F_2 we can calculate the gram of F_2 (37.99 g/mol), so:

0.148~mol~F_2\frac{37.99~g~F_2}{1~mol~F_2}=5.62~g~F_2

I hope it helps!

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.
