Answer:
The correct answer is 5 moles of CO2 are produced.
Explanation:
The given reaction:
CH₄ (g) + 2O₂ (g) ⇔ CO₂ (g) + 2H₂O (g)
The given reaction is an illustration of a combustion reaction. Any reaction in which a substance is burnt in excess of oxygen to generate water and carbon dioxide is termed as a combustion reaction. From the given equation, it is clear that the moles of the formation of the products are in the ratio 1: 2, that is, if 10 moles of H₂O is produced, the production of 5 moles of CO₂ will be produced.
Let us multiply, the given equation with 5 we get,
5CH₄ + 10O₂ ⇔ 5CO₂ + 10H₂O
Hence, it is clear that with the formation of 10 moles of H₂O, formation of 5 moles of CO₂ will also take place.

C.
Explanation:
The hand was touching the pan, which was hot, so the human reacted to it by putting the hand away from the pan.
True I believe since every person has a different temperature and sound waves.

Explanation:
Stereoisomers are isomers that have the same atom to atom connectivity but differ in the arrangement of atoms or groups in space.
Glucose and galactose are stereoisomers that have more than one stereogenic center but differ in the configuration of atoms and groups about one of the stereogenic centers. This kind of stereoisomers are also called epimers.
Glucose and galactose differ in the orientation of -H and -OH at carbon-4.
We can define atomic mass the total of number of protons and number of neutrons in an atom or isotope.
<span>So when an isotope of yttrium has 39 protons and 59 neutrons, its atomic mass is equal to;
number of protons + number of neutrons = 39 + 59 = 98</span>
