4 0

Answer:

a)  Correct: Energy will transfer from cold drink to the ice, causing the drink to get colder

Explanation:

Rey's idea is correct as energy will transfer from cold drink to the ice, causing the drink to get colder.

Energy will transfer from cold drink to ice because energy is always transferred from a body at a higher temperature to a body at lower temperature and that will allow the cold drink to get cool.

So, heat is transferred from the cold drink to the ice causing drink to get colder.

Hence, the correct option is a.

A complex ion that forms in solution has a structure that:____.
xeze [42]

Answer:

can only be determined experimentally.

Explanation:

In the early days of inorganic chemistry, the structure of complex ions remained a mystery hence the name ''complex''.

These ions appear to have structures that defied accurate elucidation. However, by diligent laboratory investigation, Alfred Werner was able to accurately determine the structure of cobalt complexes. As a result of this, he is regarded as a pathfinder in coordination chemistry.

Hence, the structure of complex ions can only be determined experimentally.

An algal bloom resulting from excess detergent and fertilizer use in the surrounding community is most likely a result of which
Lilit [14]

Answer:

c. ll and lll only

Explanation:

Algae are plant-like protists capable of photosynthesis in their cells (chloroplast). Like every other living organism that grows and reproduce, algae also requires nutrients for these processes to effectively occur.

Algae makes use of inorganic nutrients including sulphates, phosphates, nitrates etc which are found in fertilizers, detergents etc. In the presence of these compounds, algae tends to grow excessively to form a BLOOM. Hence, according to the question, nitrates and phosphates are the two inorganic nutrients algae makes use of.

What is the mass of 4.49 x 10º carbon dioxide, CO2, molecules?
Maslowich
To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol

4.49 x 10^0 / 44 g/mol = .1020 mol CO2

1 mol = 6.022 x 10^23 molecules (avogadros number)

so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
