The stock solution contains 10.5 moles of HCl per litre. A 5.5 litre solution of 2.5M HCl contains 5.5x2.5 = 13.75moles of HCl. Since every litre of stock solution provides 10.5M HCl, the amount of stock solution needed is 13.75/10.5 = 1.309L. Therefore you would dilute 1.309L of stock solution to 5.5L
If I'm correct the answer should be a series circuit :) Hopefully this helps you out
Is there choices to this question? cant answer it without choices
Let's go through each of the answers and think about why they work or don't work.
Chemical forms compounds.
Nuclear changes the element completely. We're going to use the sun as an example. The sun is in a state of plasma. It's really hot and has all these particles hitting into each other. The nucleus' of atoms are hitting into each other forming larger elements. It's real crazy. Nuclear is not correct.
Physical cannot form a compound.
The shipping container have a density of 27.77 kg/m³.
Explanation:
The formula for density is:
density = mass / volume
volume of the container = 9 m × 4 m × 3 m
volume of the container = 108 m³
density of the container = 3000 kg / 108 m³
density of the container = 27.77 kg/m³
