Question 3 (1 point)

Chemistry

Answer:

50 mol

Explanation:

Mass of methane = 800 g

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

CH₄ + 2O₂      →      CO₂ + 2H₂O

Number of moles of methane:

Number of moles = mass/molar mass

Number of moles = 800 g/ 16 g/mol

Number of moles = 50 mol

Now we will compare the moles of methane and carbon dioxide from balanced chemical equation.

                CH₄        :         CO₂

                   1           :          1

                 50          :        50

density is a physical property. would a change in the density of a sample mean that the sample has undergone a physical or chemi
shepuryov [24]

Answer:

Physical

Explanation:

The change of density alone is a physical change, but there might be some chemical change that results in physical change. For example: Burning a piece of paper will definitely change the density of the paper as some of its content is being changed into smoke which is a gas. So there will be a change in volume which in turn leads to change in density. Therefore, the change of density alone is a physical change, but the change might occur due to another chemical change.

((2.0265-2.02)/2.0265) x 100.00
lianna [129]

Answer 0.5

when reporting calculations from sig figs, report the number of sig figs in the least accurate measurement

so

((2.0265-2.02)/2.0265) x 100.00

((2.0265/2.0265) - (2.02/2.03)) X 100.00

(1.0000 -0.995) X 100.00

0.005 X 100.00

0.5
