it represents a physical change. it is not a chemical change because its chemical formula does not change unless combustion is involved.
Answer:
3-ethyl-4-methyl Heptane
Explanation:
longest chain is straight .
we start assigning number from where we are close to the branch to this mean its from left hand side. and we saw two chain 1 is ethyl and other is methyl . In alphabetical order e comes first as compare to m so we write ethyl first after that methyl and than in last we write longest chain name with ane (bcz we only have single vonds).
Answer:
Explanation:
This is a Charles Law problem => V ∝ T => direct proportionality ... that is, increasing temperature => increasing volume and decreasing temperature => decreasing volume. The empirical relationship comparing two sets of conditions is V₁/T₁ = V₂/T₂.
Given
V₁ = 462 ml T₁ = 27°C = 300K
V₂ = ? T₂ = 37°C = 310K
V₂ = V₁(T₂/T₁) = 462ml(310K/300K) = 477ml (3 sig. figs.)
