The presence of Catholicism in Australia in the late 1700s could be BEST explained by the increasing presence of A) Irish convic
defon

Answer:

Irish convicts

Explanation:

European explorers were familiar with Australia since the 1600s. However, they stepped their foot on infertile and dessert parts of the continent, so they showed no interest for this new land. Upon finding fertile land in eastern parts of the continent,  in the 1700s, James Cook claimed it a British land.  

Britain has just lost its colonies in America, so they decided to send men to this new land. However, they considered it infertile, lacking in resources and hard to live on, so they sent convicts, in, what will be known as the First Fleet, in 1788.  

Thus first contingent of ships carried around 1500 convicts, mostly Irish, with more than 100 000 convicts in the following years.

With them, Catholicism arrived in Australia, and later spread throughout the continent.

How might a hurricane in Florida cause anomalous nest data
cluponka [151]
Assuming that the nests are bird's nests and the data is a data gathered by the biologists about those nests. 
A hurricane would cause some damage to the nests that is existent and cause a remarkably low count even during breeding season. It would also influence later birds because of population weakening due to the hurricane.

The following reaction produces ethanoic acid (CHACOOH) from methanol (CH3OH) and carbon
tigry1 [53]

Answer:

\boxed{\text{300 g}}

Explanation:

We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

M_r:         32                          60

           CH₃OH + CO ⟶ CH₃COOH

m/g:        160

(a) Moles of CH₃OH

\text{Moles of CH$_{3}$OH} = \text{160 g CH$_{3}$OH }\times \dfrac{\text{1 mol CH$_{3}$OH }}{\text{32 g CH$_{3}$OH}}= \text{5.00 mol CH$_{3}$OH}

(b) Moles of CH₃COOH

\text{Moles of CH$_{3}$COOH} = \text{5.00 mol CH$_{3}$OH } \times \dfrac{\text{1 mol CH$_{3}$COOH}}{\text{1 mol CH$_{3}$OH }} = \text{5.00 mol CH$_{3}$COOH}

(c) Mass of CH₃COOH

\text{Mass of CH$_{3}$COOH} =\text{5.00 mol CH$_{3}$COOH} \times \dfrac{\text{60 g CH$_{3}$COOH}}{\text{1 mol CH$_{3}$COOH}} = \textbf{300 g CH$_{3}$COOH}\\\\\text{The maximum mass of ethanoic acid that can be produced is $\boxed{\textbf{300 g}}$}
