Answer:

The solution would be (0, 5)

Step-by-step explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

4x + 4y = 20

4x + 4(x + 5) = 20

4x + 4x + 20 = 20

8x + 20 = 20

8x = 0

x = 0

Now that we have the value of x, we can find the value of y.

y = x + 5

y = 0 + 5

y = 5

If the rate of decrease for the partial pressure of N2H4 in a closed reaction vessel is 76 torr/h , what is the rate of change f
fiasKO [112]

The reaction is missing and it's ;

N2H4 + H2 ---> 2NH3

It asks for the total pressure too.

Answer:

A) Rate of change for NH3 = 152 torr/h

B) The total pressure in the vessel will remain the same.

Step-by-step explanation:

N2H4 + H2 ---> 2NH3

1 mole of N2H4 yields 2 moles of NH3.

From the question, the rate given for N2H4 is 76 torr/h.

Thus, The rate of change for NH3 will be = 2 x 76 = 152 torr/h

Now, on the reaction side, 1 mole of N2H4 reacts with 1 mole of H2. So we have 2 moles on the left hand side.

While on the product side, 2 moles of NH3 are produced.

So the total pressure will remain the same because for every 2 moles on the reaction side, 2 moles are gotten on the product side.

A scientist estimated that a mixture would need 4 milliliters of a chemical to balance. The actual amount needed was 7 millilite
Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.
