The concentration of HCl solution is calculated as follows
write the equation for reaction
NaOH + HCl = NaCl + H2O
find the moles NaOH = molarity x volume /1000
= 5 x2/1000 = 0.01 moles
by use of mole ratio between NaOh to HCl which is 1 :1 the the moles of Hcl is also = 0.01 moles
concentration is therefore = moles/volume x1000
= 0.01/10 x1000 = 1M
There are certain processes in nature that produce many of these radioactive<span>isotopes. For instance, some </span>radioactive<span> nitrogen is produced in the atmosphere when high energy cosmic radiation from the sun hits the earth. Other </span>radioactive<span>isotopes are only available by artificial production. good luck</span>
Answer:
Synthesis
Explanation:
I just did the test and got it right!!
Answer:
A. mass X to moles X to moles Y to liters Y
Explanation:
Remember: moles are the great converter. They're basically just a made-up concept meant to facilitate conversions!
Starting with mass X, you must then convert to moles X.
Once you have moles X, convert moles Y. Think of a chemical equation: the mole ratios are the coefficients!
Once you have moles Y, all you have to do is convert to liters Y. You can do this with the molarity equation M = mol/L, or if it's a gas at STP you know the conversion!
Answer:
The conductance will increase as the concentration of the electrolyte is increased.
Explanation:
The ions are what carry the charges from one electrode to another. The more there are, the easier it is for electrons to get across the solution of electrolyte,
