2, 8, 8, 16 and 32. They are the electron level le she'll beers and each never represents how much can fit in
Answer:
1. naoh + h₂o → na⁺ + oh⁻ + h₂o + heat
2. naoh + hcl → nacl + h₂o
explanation:
1. the dissolving of naoh in water is an exothermic reaction resulting a heat. it also causes the dissociation of naoh to its ions (na⁺ and oh⁻).
so, the balanced equation will be naoh + h₂o → na⁺ + oh⁻ + h₂o + heat.
2. the reaction between acid and base resulting salt and water. it is considered as a neutralization reaction.
the reaction between hcl and naoh will give sodium chloride and water and the balanced equation will be naoh + hcl → nacl + h₂o.
Explanation:
<span>Ethene (C2H4) is an alkene which means this compound has a double bond between the carbons. The hybridization hence is sp2. In this hybridization, the 2s orbital mixes with only two of the three available 2p orbitals, forming a total of 3 sp2 orbitals with one p-orbital remaining.</span>
Explanation:
Gasoline has many different types of hydrocarbons. This makes it a mixture.
78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide and small concentrations of other elements. <span />
