Answer:

See explanation and image attached

Explanation:

The formula here is C4H10.

When we talk about constitutional isomers, constitutional isomers are compounds having the same molecular formula but different atom-to-atom connectivity.

The two main constitutional isomers of the formula C4H10 are butane and 2-methylpropane (iso-butane). The both structures are shown in the image attached.

Which of the following is an anion?Al3+ Mg2+ O2– H Save

JulijaS [17]

An anion is an ion with a negative charge. The minus sign, when attached to the end of an ionic compound, indicates that this has a negative charge, while a plus sign indicates a positive charge.

O2- is the only compound listed that satisfied this. It is the anion.
Answer is 02-

A fossil was analyzed and determined to have a carbon-14 level that is 70 % that of living organisms. The half-life of C-14 is 5

Citrus2011 [14]

Answer: 2948

Explanation:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

$t_{\frac{1}{2}}=\frac{0.693}{k}$

$k=\frac{0.69}{t_{\frac{1}{2}}}=\frac{0.693}{5730}=1.21\times 10^{-4}years^{-1}$

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant = $1.21\times 10^{-4}years^{-1}$

t = age of sample = ?

a = let initial amount of the reactant = 100

a - x = amount left after decay process = $\frac{70}{100}\times 100=70$

$t=\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{70}$

$t=2948years$

Thus the fossil is 2948 years old.
