Answer: 7
Explanation:
Before a number but after a decimal. The zeros at the end would usually mean that it doesn't count but since the numbers are before the zeros and after a decimal it's 7 sig figs
According to Le Chatelier’s principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas.
Explanation:
- NaCl + AgNO3<------>NaNO3 + AgCl.
- In any reaction a temperature increase uplifts the reaction that absorbs heat which is known as the endothermic reaction.
- The product which absorbs heat, shifts the reaction to the left hand side.
- This shows that the reverse reaction or backward reaction is endothermic.
- if the temperature is increased for an endothermic reaction, essentially a reactant is being added, so the equilibrium shifts toward products.
- Le Chatelier’s principle states that it can be used to predict the behavior of a system due to changes in pressure, temperature, or concentration.
- If the concentration of reactants is increased the reaction is shifted to the right, while increasing the concentration of products will shift the reaction to the left side.
Answer:
3 significant figure
Explanation:
Trailing zeros in a number are significant ONLY is the number contains a decimal point.
So if it was 100cm with out the decimal point would only have 1 significant figure.
