Explanation:
The property of a substance to resist the flow of motion is known as viscosity. And, more is the density of a substance more will be its viscosity.
Whereas, lesser is the density of a substance then it is easy for the substance to move.
This means that more is the viscosity of a substance least will be its flow and when a substance has lesser viscosity then it will readily flow from one point to another.
Thus, we can conclude that the viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liquid with the highest viscosity will reach the bottom last.
Fluorine-18 is a radioactive isotope of the element fluorine. According to Wikipedia, its half-life is 109.771 minutes, which means the amount present is halved every 109.771 minutes.
You can use the formula for half-life, such that
. You begin with 135 mg fluorine-18. We don't even need to plug in to the formula to see that after 110 min, the amount has halved to equal
67.5 mg.
15.3 litres of water will be produced if we take 1.7 litres of Hydrogen
Explanation:
Let's take a look over synthesis reaction;
<u> </u><u />
<u>Balancing the chemical reaction;</u>
<u> </u><u />
Thus, 2 moles of hydrogen molecules are required to form 2 moles of water molecules.
<u>Equating the molarity;</u>
<u /> =
(Since, the molecular mass of hyd and water is 2 and 18 respectively)
x=
x= 15.3 litres.
Thus,15.3 L of water will be produced if we take 1.7 litres of Hydrogen in a synthesis reaction.
The quality of being hot; high temperature.
I hope this helps <3
Answer:
I'm not 100% sure but I think it would be constant
