Explanation:
When carbon atom tends to form single bonds then its hybridization is 
, when carbon atom tends to form double bond then its hybridization is 
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:
Answer:
answering this for points! Sorry! but its probably A OR C
Explanation:
In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.
<h3>What is a formula unit?</h3>
A formula unit is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations.
- Step 1: Convert 40.32 kg to g.
We will use the conversion factor 1 kg = 1000 g.
40.32 kg × (1000 g/1 kg) = 4.032 × 10⁴ g
- Step 2: Convert 4.032 × 10⁴ g to moles.
We will use the molar mass of NaHCO₃ as the conversion factor.
4.032 × 10⁴ g × (1 mol/84.01 g) = 479.9 mol
- Step 3: Convert 479.9 moles to formula units (fu).
We will use Avogadro's number as the conversion factor.
479.9 mol × (6.022 × 10²³ fu/1 mol) = 2.890 × 10²⁶ fu
In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.

Answer:
200 g of NaOH
Explanation:
For this solution of NaOH
2.50 M means that in 1L of solution, we have 2.5 moles
Mol . molar mass = Mass
2.5 m . 40 g/m = 100 grams
In 1 L, we have 100 grams of solute, so in 2L, we have the double
200 g of NaOH
