Leading up to this, calcium gave up 2 valence electrons and thus was denoted as a cation. These 2 electrons were transferred to bromine, which received an overall negative charge because of the addition of 2 valence electrons in its valence shell, and thus formed a negatively charged ion, an anion.
Both formed an ionic bond, due to the electrostatic charge of attraction between the 2 oppositely charged ions. If many ions of Ca and Br are present and numerous ionic bonds have formed it will undergo an arrangement which is that of an ionic lattice, type of structure.
'The slower moving' type of water molecules have the greater tendency to condense to the liquid state from the gaseous state.
If the molecules speed up it means that energy has been added to the system. Eventually, therefore, the water would evaporate into steam (or water vapour) provided the energy was continued to be added to the system.
Vice versa if the molecules are slowed down then the water molecules in gas would condense and change their state from gas to liquid.
Condensation is the process where water vapour becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapour.
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapour that it cannot hold any more water.

Answer:
No. You can not simplify a coefficient of.
Explanation:
:)
Answer:
20 g/L
Explanation:
To know what happens with the concentration, we must calcute the limit of the function where t → ∞. The limit is the value that the function approach when t intend to a value. So:
Dividing both for "t"
The limit of 1/t when t intend to infity is 0, which is demonstrated in the graph below, so:
The concentration will approach 20 g/L.
Answer:
D
Explanation:
On the left hand side there are a total of 4 hydrogen and 2 oxygen but on the right hand side there Is only 2 hydrogen and 1 oxygen
