The ionic charge of oxygen is -2.
Hope this helps! ;)
A bond is when two substances are connected to each other by chemical means
Average kinetic molecular energy is actually defined by temperature, so any gas, no matter the volume or pressure, will have the same average kinetic molecular energy as long as its temperature is the same. Therefore, Gases A, B, and D all have the same average molecular kinetic energy, since they are at 12<span>°C.</span>
Answer:
Carbon dioxide
Explanation:
<em> laboratory to have a pH of less than 7.0.</em>
Carbon (IV) oxide in the atmosphere is capable of dissolving into the distilled water to form a weak acid. Any pH that is less than 7.0 is acidic while any pH above 7.0 is alkaline or basic.
First, the carbon (IV) oxide enters the water through an equilibrium with the atmosphere:
Thereafter, aqueous carbon (IV) oxide can then react with water to form a weak carbonic acid:
The substance is not composed entirely of cocaine, it is mixed with other materials. The purity refers to what percentage of the powder is cocaine, and what percentage is other materials.
Purity can be important in crime investigations to find out the samples value, and to pair it with previously found samples of equal purity to deduce that they came from the same source.
