The percent composition of what? It should ask to find the percent composition of one of the parts like copper, sulfer, or water.
I think the answer is 10g
when you freeze a specific amount of water into an ice cube, only the form and the density is changed, while the mass will be pretty much the same.
Probably the mass of the melted water will be a little bit less than the cube (if count the mass that released to the air) , but the amount will NOT BE SIGNIFICANT.
Answer:
7.82x10^24 molecules of water
Explanation:
H2O=18.015 g/mol Avogadro's #=6.022x10^23 molecules
0.234L x 1000g/1L x 1 mol H2O/18.015 g x 6.022x10^23 = 7.82x10^23 molecules of water
The answer is True. Transportation is used by cars, airplanes, trains, and many other things.
Answer:
The correct answer is reaction will achieve equilibrium by forming more products and will move in left to right direction.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
- If Q > , then the equilibrium will shift in left direction or in backward direction.the reaction will move back to the formation of reactants from the product
- If Q < , then the equilibrium will shift in right direction or in forward direction.The reaction will form more products
