500/92 = 5.43 mol of C7H8
1:1 mol ratio
Mass = mol x Mr = 5.43 x 137 = 743 g (theoretical yield)
Percentage yield = ( actual yield / theoretical yield ) x 100
500/743 x 100 = 67.3% 1dp

kkurt [141]

Answer:

The lateral area is $4,608\pi\ in^{2}$ or $32\pi\ ft^{2}$

Step-by-step explanation:

we know that

The lateral area of a cylinder (pillar) is equal to

$LA=2\pi rh$

Remember that

1 ft=12 in

Find the lateral area in square inches

we have

$r=8\ in$

$h=24\ ft$ ----> convert to inches

$h=24*12=288\ in$

substitute the values

$LA=2\pi (8)(288)$

$LA=4,608\pi\ in^{2}$

Find the lateral area in square feet

we have

$h=24\ ft$

$r=8\ in$ -----> convert to feet

$r=8/12=(2/3)\ ft$

substitute the values

$LA=2\pi (2/3)(24)$

$LA=32\pi\ ft^{2}$

Explain why the negation of “Some students in my class use e-mail” is not “Some students in my class do not use e-mail”.

Olenka [21]

Answer with Step-by-step explanation:

Since we have given that

Some students in my class use e-mail.

It is a type of 'E' statements.

Its negation should be No students in my class use e-mail.

Because if we use "Some students in my class do not use e-mail”.

It also implies some students in my class still use e-mail.

But negation contains only opposite of given statement.

So, Some students in my class do not use e-mail” is not true.
