Answer:
A solution of NaOH has concentration 1.2M. Calculate the mass of NaOH in g/dm3 in this solution. = 1.2x 40x 1 = 48 g 3.
Answer:
Outside air
Nose
Lungs
Bloodstream
Cell
Explanation:
We breathe in oxygen from the outside air in through our nose and it travels to our lungs. Inside our lungs, we have Avioli's that diffuse oxygen into our bloodstream and the bloodstream helps the oxygen travel into our cells.
Hope this helps :)
H-O bond is a covalent polar bond, also O is more electronegative than H, so
The oxygen atom in water molecule has
a partial negative charge.
The reason why is because particles are moving faster and possess greater kinetic energy due to the increase in temperature, this causes greater frequency or number of collisions to take place and also allows for a higher likelihood that upon reactant molecules colliding they will undergo the reaction process as they will have achieved the required energy needed for the reaction to start. Thus overall having a greater change in quantity conversion of reactants to products within a shorter period of time, thus increasing the reaction rate.
Answer:
The moles of solute
Explanation:
When you make a dilution, moles of solute does not change when you add solvent.
In concentrated solution, you have x moles of solute, that will be the same in the diluted solution.
Relation between molarity or volume of concentrated and diluted solutions is called, "dilution factor".
When you calculate the dilution factor: you use this formula
Molarity concentrated . Concentrated volume = M diluted . Diluted volume
M concentrated / M Diluted = Diluted volume / Concentrated volume
