From the figure we can notice that the tip is ended surely before 9 cm .

Also , the tip crossed two cuts after 8 .

Therefore , it is greater than 8.2 .

Now , if we see that the tip end between 2 and 3 .

Therefore , the best estimate is 8.25 cm .

Hence , this is the required solution .

What coefficients are needed to balance the equation for the complete combustion of methane? Enter the coefficients in the order
Julli [10]

Answer:

The balanced equation is given below:

CH4 + 2O2 —> CO2 + 2H2O

The coefficients are: 1, 2, 1, 2

Explanation:

The equation for the Combustion of methane (CH4) is given below:

CH4 + O2 —> CO2 + H2O

Now we can balance the equation above as follow:

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:

CH4 + O2 —> CO2 + 2H2O

Now, there are a total of 4 atoms of O on the right side and 2 atoms on the left. It can be balance by putting 2 in front of O2 as shown below:

CH4 + 2O2 —> CO2 + 2H2O

Now the equation is balanced.

The coefficients are: 1, 2, 1, 2

Answer:

48g of Magnesium.

Explanation:

We know that:

Mole=given mass/molar mass

Then, moles of aluminum = 54/27 = 2.

A/c to question ,

For 2 moles of magnesium it's mass is 2×24=48g.

Hence, the required mass for same number of magnesium atoms is 48g.
