calculate the mass of water formed when 4g of methane is burnt in excess oxygen​

Answers

CH4 + 02 → H20 + CO2

balance equation

CH4 + 2O2 → 2H2O + CO2

4 ÷ ( 12 + 4 ) = 0.25 mol

1 : 2

no mole of H2O = 0.25 × 2 = 0.5 mol

mass of H2O = 0.5 × ( 2 + 16 ) = 9g

9. Given similar triangles ABC and PQR with AB = 4 and PQ = 7.
Fill in the following chart stating the scale factor, ratio of perimeters,
and ratio of areas:

Answers

Given:

Similar triangles ABC and PQR with AB = 4 and PQ = 7.

To find:

The scale factor, ratio of perimeters, and ratio of areas.

Solution:

In similar figures the scale factor is the ratio of side or image and corresponding side of original figure.

In similar triangles ABC and PQR, the scale factor is

[tex]k=\dfrac{PQ}{AB}[/tex]

[tex]k=\dfrac{7}{4}[/tex]

The scale factor of triangle ABC to triangle PQR is [tex]\dfrac{7}{4}[/tex].

The ratio of the perimeters of similar triangles is equal to the ratio of their corresponding sides.

[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=\dfrac{AB}{PQ}[/tex]

[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=\dfrac{4}{7}[/tex]

[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=4:7[/tex]

The ratio of the perimeters is 4:7.

The ratio of the areas of similar triangles is equal to the ratio of squares of their corresponding sides.

[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{AB^2}{PQ^2}[/tex]

[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{4^2}{7^2}[/tex]

[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{16}{49}[/tex]

[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=16:49[/tex]

Therefore, the ratio of the areas is 16:49.
