Answer:
The correct answer is D) The volume of the gas will increase.
Explanation:
According to Charles's Law, at constant pressure, as the temperature (T) of a gas increases, the volume (V) increases and vice versa. This is observed according to the formula:
V1 / T1 = V2 / T2
When wood id burnt, 30 grams of ash are formed due to the chemical changes that occurred.
The missing 370 grams are evaporated into the air where they form other particles and substances.
<span>Lewis structure for 3 nitrogen-containing compounds can be drawn as:

:N:::N: , ::N:H
For the Lewis Structure for N₃⁻, we place a double bond between the Nitrogen atoms to complete the outer shells on all atoms and we will only use the available valence electrons for the molecule. <span>There are 16 valence electrons available.</span>
Explanation:
Water can be purified from through...
Filtration - This involves the use of filter paper to remove solid objects found in water.
Boiling - This involves keeping water at 100 deg celcius for a while through application of heat and this kills microorganisms in the water.
Addition of alum - Alum causes very fine and small particles that are suspending in water to stick together making them large enough to be removed through filtration.
Chemicals used in water treatment...
Chlorine - Chlorine is used to kill bacteria, viruses and other disease causing pathogens found in water
