Answer:
The town should find a new source of water.
Explanation:
Step 1: Convert the mass of copper to milligrams
We will use the conversion factor 1 g = 1000 mg.
0.002 g × (1000 mg/1 g) = 2 mg
Step 2: Convert the mass of solution to kilograms
We will use the conversion factor 1 kg = 1000 g.
1000 g × (1 kg/1000 g) = 1 kg
Step 3: Calculate the concentration of Cu in ppm (mg/kg)
2 mg/1 kg = 2 ppm
This is over 1.3 ppm, so the town should find a new source of water.
Explanation:
Well Mercury I is a difficult one, but I if it is at room temperature then, I it would stay a liquid but below room temperature it would be melt and above room temperature it would freeze
The correct option is A.
Option A is the correct answer because the question asked in that option can easily be verified by using scientific method. The question is considered to be science based because scientific methods can be used to answer the question. To determine the density of water, all that one has to do is to find the mass and the volume of a sample of water and then divide the ratio.
Thank you for posting your question here at brainly. The <span>mole fraction of co if the h2 mole fraction is 0.22 and the o2 mole fraction is 0.58 is 0.20, below is the solution:
</span>
mole fraction CO + mole fraction H2 + mole fraction O2 = 1
mole fraction CO = 1 - ( 0.22 + 0.58)=0.20
What is your full question ??
