Answer:
D
Explanation:
solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M NaOH Can resist pH change when there is little addition of either acid or base, hence it is a buffer solution
Answer:
It has 3 sigma bonds
Explanation:
A sigma bond is a covalent interaction between two atoms, these bonds are the strongest type of covalent bonds and they are formed by the overlap of atomic orbitals.
The nitrogen is bond to the bromine atoms through sigma bonds, which means that exist 3 sigma bonds in the molecule.
this molecule has a trigonal pyramid geometry due to the free pair of nitrogen electrons.
The answer in here is d)48 lit. We know this when we do the following procedure:
<span>kerosene=18%
so petrol =82%
after
kerosene =15%
petrol=85%
so 3% =8
lit
so total kerosene in the mixture =(8x18/3) =48 lit
</span>Hope this is useful
Answer: Id.k It weird I get confused too
Explanation:
Don't look or ask em
To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol
4.49 x 10^0 / 44 g/mol = .1020 mol CO2
1 mol = 6.022 x 10^23 molecules (avogadros number)
so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
