M = moles of solute / liters of solution
2.00 M = x / 10.0 L
x = 20.0 mol
Suppose the molarity was listed as 2.0 M (two sig figs). How to display the answer? Like this:
20. mol
Answer:
The blanks can be completed with words in the following sequence
1) elements
compound
2) atom
3) matter
4) compound
5) chemistry
6) reactants
product
Explanation:
In H2SO4, atoms of hydrogen, sulphur and oxygen represent different elements that are combined to form the compound.
The smallest indivisible unit of matter that still retains all the properties of matter is an atom. Matter is anything that has weight and occupy space.
Atoms combine in fixed ratios to form compounds. Chemistry studies matter scientifically and pays specific attention to the changes that matter undergoes.
Considering the reaction of photosynthesis, water and carbon dioxide combine to give glucose so the water and carbon dioxide are reactants while the glucose is the product of the reaction.
If you don't wash the thermometer, residual NaOH will react with the HCl solution. This is a highly exothermic reaction and will change the temperature of the solution, and thus throw off your measurement.
According to the density of the liquid, we can get the mass of liquid is 70*0.85=59.5 g. So the total mass is 59.5+60.75=120.25 g.
