Answer:

B

Step-by-step explanation:

-The balanced chemical reaction of oxygen and water is written as:

2H_2_{(g)}+O_2_{(g)}->2H_2O_{(l)}

-You notice that 2 moles of hydrogen gas reacts with one mole of oxygen gas to form 2 moles of water

Find the deference between
maxonik [38]

Answer:

$5520

Step-by-step explanation:

Given data

Principal=  $24000

Rate=10%

time= 2 years

Firstly, the compound interest is given as

A=P(1+r)^t

A=24000(1+0.1)^2

A=24000(1.1)^2

A=24000*1.21

A=$29040

The simple interest is given as

A=P(1+rt)

A=24000(1+0.1*2)

A=24000(1.2)^2

A=24000*1.44

A=$34560

Hence the difference is

=34560-29040

=$5520

3. Find the value of x and explain your reasoning<br><br> (4x - 8)<br> (3x + 10) (11x + 2y)º
jolli1 [7]

The question is an illustration of angles on a straight line

The value of x is 25.4

<h3>How to determine the value of x</h3>

In the figure, angles 1 and 2 are angles on a straight line

Where:

  • Angle 1 = 4x - 8
  • Angle 2 = 3x + 10

So, we have:

4x - 8 + 3x + 10=180

Collect like terms

4x  + 3x =180 - 10 + 8

7x =178

Divide through by 7

x =25.4

Hence, the value of x is 25.4
