Answer:
Methyl group
Explanation:
From the diagram shown, we can see that the family group CH3 is attached to the structure.
This is simply called a methyl group because it is derived from me than and written that way to show the direct bonding between carbon and the 3 hydrogen atoms.
Answer:
This process is called Photochemical smog

Explanation:
Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.
<h3>What kinds of bonds exist?</h3>
- Covalent bonds: These are formed between nonmetals and electrons by sharing electrons.
- Ionic bonds: These are formed between metals, which lose electrons, and nonmetals, which gain electrons.
- Metallic bonds: There are formed between metals. Electrons are delocalized in a cloud.
Water, H₂O, is a molecule made of 2 nonmetals: oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as covalent bonds.
Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

Answer:
Q = 270 Joules (2 sig. figs. as based on temperature change.)
Explanation:
Heat Transfer Equation of pure condensed phase substance => Q = mcΔT
Mixed phase (s ⇄ l melting/freezing, or l ⇄ g boiling/condensation) heat transfer equation => Q = m∙ΔHₓ; ΔHₓ = phase transition constant
Since this is a pure condensed phase (or, single phase) form of lead (Pb°(s)) and not melting/freezing or boiling/condensation, one should use
Q = m·c·ΔT
m = mass of lead = 35.0g
c = specific heat of lead = 0.16J/g°C
ΔT = Temp change = 74°C - 25°C = 49°C
Q = (35.0g)(0.16J/g·°C )(49°C) = 274.4 Joules ≅ 270 Joules (2 sig. figs. as based on temperature change.)
