Answer:
When carbon dioxide is passed through lime water for a short time,it turns lime water milky due to formation of a white precipitate of calcium carbonate.
Explanation:
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
Hey there!
The reason why <span>ocean currents move from the equator towards the poles are because the wind push the water's away from the equator and toward the poles, so pretty much, let's blame this on the wind, it's the wind's fault not ours. But yes, your correct answer to this question above would be of that the wind's push the water's away from the equator and to the poles.
Hope this helps you buddy!</span>
I want to say it's C, it's been awhile since I was in science class learning about that stuff lol
Some fossils provide clues to the environment and climate of the time the organism lived.
Answer:
As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+
Explanation:
The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.
However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a 
species which is simply a diatomic ion but not a compound.
