Answer:
2) 14.5 moles
Explanation:
The balanced chemical reaction for the formation is:
If 14.5 moles of are produced, is needed to use the stoichiometry of the chemical reaction to calculate how many moles of reacted to form this quantity:
Therefore 14.5 moles of are produced by 14.5 moles of
The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.
For example:
The balanced chemical equation for production of water from hydrogen and oxygen is:
That means 2 moles of reacts with 1 mole of to give 2 moles of .
The given formula is .
Hence, 4 represents the number of moles in formula that is 4 moles of .
The number of atoms of sodium, in is:
The number of atoms of sulfur, in is:
The number of atoms of oxygen in, in is:
Answer:
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous reacts to form a dilute mixture solution of (carbonic acid ).
The reaction is
This is a forward reaction. And the symbol shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
Answer: oil spill, forest fire
Explanation:
The short term environmental change is a change that occur in an environment which exerts it's effect over the environment and the living beings for a short duration. The damage caused by the short term environmental change can be recovered in a short time. The oil spill and forests fire are the example of short term environmental changes.
The oil spill will reduce the abundance of the aquatic species until the oil is circulated out at the bay of the water body therefore, it is a short term environmental change.
Forests fire will remain ignited for a short period but can be destructive enough to cause damage to flora and fauna species. As time passes the reduced populations of flora and fauna can be recovered again.
