4 significant figures. Use a rule called the Atlantic-Pacific rule where if the period is absent (Atlantic), you would start counting the numbers from right to left. If the period is present (Pacific), then start counting the numbers from left to right. Since the period is present, start from 5 and there are 4 digits including 5.
B. It is not accelerating since equal and opposite forces cancel each other. Hope it helps
3433Explanation:
the awser sucks and its not RIGHT
Explanation:
forward reaction
a reaction in which reactent react to form product is known as forward reaction
reverse reaction
a reaction in which product react to form reactent is known as reverse reaction
At equilibrium stage
In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.
changing amount of reactent and product
lechatlier principle
" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "
I think B qualitative is the answer
