Answer:
thousands
Explanation:
here is why because think about it most oceans are measured by how much goes in it every day by the thousands of gallons of sea water so i hope this helps you understand your question
Answer:
Definition of Inert. An inert chemical is one that is stable and unreactive under specified conditions. ... However, most of the noble gases have now been observed to form compounds, although generally under unusual conditions. Helium and neon are highly inert; they form no compounds.
Answer:
a) if the solid floats
Explanation:
Hello,
In this case, since the determination of the volume of a solid when submerged in water requires to use an analytical balance to measure the mass, but also it is necessary that the solid sinks in order to completely displace the what in the graduated cylinder which accurately provides the volume of the solid via its scale. Therefore, a draw back is a) if the solid floats since the water is not completely displaced.
Best regards.
Answer:
7.37 mL of KOH
Explanation:
So here we have the following chemical formula ( already balanced ), as HNO3 reacts with KOH to form the products KNO3 and H2O. As you can tell, this is a double replacement reaction,
HNO3 + KOH → KNO3 + H2O
Step 1 : The moles of HNO3 here can be calculated through the given molar mass ( 0.140 M HNO3 ) and the mL of this nitric acid. Of course the molar mass is given by mol / L, so we would have to convert mL to L.
Mol of NHO3 = 0.140 M 
30 / 1000 L = 0.140 M 0.03 L = .0042 mol
Step 2 : We can now convert the moles of HNO3 to moles of KOH through dimensional analysis,
0.0042 mol HNO2 ( 1 mol KOH / 1 mol HNO2 ) = 0.0042 mol KOH
From the formula we can see that there is 1 mole of KOH present per 1 moles of HNO2, in a 1 : 1 ratio. As expected the number of moles of each should be the same,
Step 3 : Now we can calculate the volume of KOH knowing it's moles, and molar mass ( 0.570 M ).
Volume of KOH = 0.0042 mol ( 1 L / 0.570 mol ) ( 1000 mL / 1 L ) = 7.37 mL of KOH
Okay , so on Google this question will pop up if you look up minimilizing conduction explain.
