There are ________ mol of bromide ions in 0.700 L of a 0.400 M solution of AlBr
denis23 [38]

Answer:

The number of moles of AlBr3 = Molarity × Volume

= 0.400 × 0.700

= 0.28 moles

1 mole of AlBr3 gives 3 moles of Br- ions

That is

AlBr3 = Al3+ + 3Br-

Therefore, 0.045 moles of AlBr3 will yield 3 × 0.28 = 0.84 moles

Thus; they are 0.84 moles of bromide ions

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.

Which of the following accurately describes the behavior of water when subjected to temperature change?
77julia77 [94]
I believe this is the best one:
B. The volume of water will increase if cooled from 3°C to 2°C.

I don't think D) because water expands from 4°C to 0°C

"When liquid water is cooled, it contracts like one would expect until a temp of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point."
