Ede4ka [16]

<u>Answer:</u> In a chemical reaction, the total mass of the particles in the system stays the same

<u>Explanation:</u>

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  

This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.

Every balanced chemical reaction follows law of conservation of mass.

<u>For Example:</u> Formation of water molecule

2H_2+O_2\rightarrow 2H_2O

Total mass on reactant side = [2(2\times 1)+(2\times 16)]=36g/mol

Total mass on product side = [2((2\times 1)+16)]=36g/mol

Hence, in a chemical reaction, the total mass of the particles in the system stays the same

Which type of orbitals overlap to form the sigma bond between C and N in H−C≡N:? Which type of orbitals overlap to form the sigm
zysi [14]

Explanation:

When carbon atom tends to form single bonds then its hybridization is sp^{3}, when carbon atom tends to form double bond then its hybridization is sp^{2} and when a carbon atom is attached to a triple bond or with two double bonds then its hydridization is sp.

For example, in HCN molecule there is a triple existing between the carbon and nitrogen atom.

So, hybridization of carbon in this molecules is sp. Moreover, nitrogen atom is also attached via triple bond and it also has a lone pair of electrons. Hence, the hybridization of nitrogen atom is also sp.

Thus, we can conclude that s and p type of orbitals overlap to form the sigma bond between C and N in H−C≡N:

Use the periodic table to match each of the following element symbols to its name, atomic mass, or atomic number
uysha [10]

Answer:

Explanation:

From the periodic table, the element designated as Sn is tin. Sn is derieved from a latin name of the metal called Stanum

Selenium Se is a group 6 element. It belongs to the same group with oxygen, sulfur and tellurium. This substance has an atomic weight of 78.96g/mol

Oxygen is a group 6 element with an atomic mass of 16. The atomic mass is the number of protons in the nucleus of this atom.
