Why was meteorology such a late developer compared to other branches of science?

Answer:

Because of the difficulties of measuring the atmosphere's properties above the earth's reachable surface

Explanation:

Hello,

In this case, meteorology is the branch of science studying the atmosphere in its weather processes and forecasting and it had a late development because of the difficulties of measuring the atmosphere's properties above the earth's reachable surface. We cannot forget that even nowadays, it is very difficult to predict upcoming weathers with the 100 % assurance and with many days in advance.

Best regards.

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.

Aluminum sulfate reacts with barium chloride to form the insoluble compound, barium sulfate. The reaction proceeds according to

Kaylis [27]

Answer: $BaCl_2$ is the limiting reagent and $Al_2(SO_4)_3$ is the excess reagent.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of aluminium sulphate}=\frac{150g}{342.15g/mol}=0.438moles$

$\text{Moles of barium chloride}=\frac{200g}{208.23g/mol}=0.960moles$

The balanced chemical reaction is:

$Al_2(SO_4)_3+3BaCl_2\rightarrow 2AlCl_3+3BaSO_4$

According to stoichiometry :

3 moles of $BaCl_2$ require = 1 mole of $Al_2(SO_4)_3$

Thus 0.960 moles of $BaCl_2$ will require= $\frac{1}{3}\times 0.960=0.320moles$ of $Al_2(SO_4)_3$

Thus $BaCl_2$ is the limiting reagent as it limits the formation of product and $Al_2(SO_4)_3$ is the excess reagent as it is left.
