When a mixture of oxygen and hydrogen is ignited in a test tube, the reaction shown occurs. Hydrogen + Oxygen → Water + Energy S
grin007 [14]

Answer:

products

Explanation:

In chemistry, chemical reactions is the combination of two or more substances to yield other substances. The substances that react is called REACTANTS while the substances formed after the reaction is called PRODUCTS.

According to this question, a mixture of oxygen and hydrogen is ignited in a test tube as follows:

Hydrogen + Oxygen → Water + Energy

In this reaction, the substances being combined (usually found on the left side of the equation) are hydrogen and oxygen. Hence, oxygen and hydrogen are REACTANTS. Also, the substances produced as a result of the reaction is water (H2O). The PRODUCTS of the reaction is WATER.

s fo"rmed when one atom of carbon (atomic number 6) is covalently" bonded with two atoms of oxygen (atomic number 8). What is th
sweet [91]

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.

<u>Explanation:</u>

A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.

Carbon is the 6th element of the periodic table having electronic configuration of 1s^22s^22p^2

This element requires 4 electrons to complete its shell.

Oxygen is the 8th element of the periodic table having electronic configuration of 1s^22s^22p^4

This element requires 2 electrons to complete its shell.

So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.

Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.
