Answer:
If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants.
Explanation:
If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. Or, if we remove reactants from the system, equilibrium will also be shifted to the left
Answer:
0.15M
Explanation:
The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.
You need to calculate the number of moles from the given grams. The molar mass of KOH is (39.098+ 16 +1.008)= 56.106g. To calculate the mols of KOH, 
× 
= 0.44558... mol, you see that the grams unit cancel out leaving you with mol as the unit.
The volume is given in L already so no need to do any conversion. M= 
= 0.1485M ≈ 0.15M
Answer:
The correct option is;
Scientists can drill deep into the ice to collect ice cores which contain trapped atmospheric gases
Explanation:
The study of past climates also known as paleoclimatology, is accomplished by acquiring information from proxy data sources which are physical environment characteristics that are preserved through time to remake the conditions of past climate
Past physical environmental characteristics, from which information about ancient climate can be gained are stored in nature's climate variability records including, ice cores, rings in tree stems, fossil pollen, sediments found in the waters of the ocean
The proxy sources provide a means of understanding the conditions of ancient climate before advent of climate measurement.
Therefore, one way that analyzing ice benefits scientists who study ancient climates is that scientists can drill deep into the ice to collect ice cores which contain trapped atmospheric gases from past climates.
Answer:
17.6kJ
Explanation:
The mass of ethanol given is 161.g
Now we first find the number of moles from this.
Number of moles = 
Molar mass of C₂H₅OH = 2(12) + 5(1) + 16 + 1 = 46g/mol
Number of moles of ethanol = 
= 3.5mol
Since the heat of fusion is 5.02kJ/mol;
Heat of fusion is a measure of the amount of energy needed to melt a substance.
Amount of energy needed to melt = 3.5mol x 5.02kJ/mol
= 17.6kJ
