Answer:
4 moles
Explanation:
= 
= 2 (moles)
CH4 + 2O2 → CO2 + 2H2O
1 : 2 : 1 : 2
2 (moles)
⇒ 
= 2 × 2 ÷ 1 = 4 (moles)
You should use the joules (J) unit of measurement.
Answer:
For example, N2O4 is referred to as dinitrogen tetroxide, not dinitrogen tetraoxide, and CO is called carbon monoxide, not carbon monooxide.

Explanation:
Answer:
There is no way of finding the volume of an irregular shape.
We cant find the volume of an irregular solid because we can never measure the volume of curves that are present in an irregularly shaped object. so we tend to place this irregular object in a beaker of water so that the volume of water displaced by it will actually show us the volume of object itself. And now we can conclude that water displacement is an effective way of measuring the volume of an irregular solid there is no way of finding the volume of an irregular shape.
Answer:-
Increases
Explanation:-
Atomic size refers to the distance between the nucleus and the outermost valence shell.
As you move down a group, a new shell is added. So the distance of the valence shell increases from the nucleus as we go down a group.
Thus as you move down a group in the periodic table atomic size generally
