carbon atoms can form single, double, or triple bonds because they have four valence electrons.

true
false

Answer : Yes, the given statement is true.

Explanation :

As we know that the carbon has four valence electrons. The carbon is the only atom which has catenation property.

Catenation : It is a self-linkage of atoms of the same element into a longer chains. It forms covalent bonds with the other carbon atoms and form longer structures.

The covalent bonds are formed by the sharing of electrons.

Carbon atoms can form single, double, or triple bonds.

Single bond : It is a type of chemical bond in which a pair of electrons is shared between the two carbon atoms.  

Double bond : It is a type of chemical bond in which 2 pairs of electrons are shared between the two carbon atoms.  

Triple bond : It is a type of chemical bond in which 3 pairs of electrons are shared between the two carbon atoms.

Hence, the given statement is true.

i'm assuming that the correct answer is indeed the first one/ "a"..

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
