Answer:
Option D - It tells which compounds will dissolve in water.
Explanation:
It is used to predict whether or not a given ionic compound is soluble.
Answer:
north pole, south pole, and magnetic field
Explanation:
the earth basically has a giant bar magnet inside it( the axis). Earth has a north pole, a south pole, and a magnetic field which are the same things that a bar magnet has.
B is the correct answer I hope that this help
We are given that:
100 mL total solution with 1:50 povidone iodine solution
This means that there is 1 mL of povidone iodine solution
per 50 mL of total solution. Since we are given a total of 100 mL solution,
therefore we have an initial amount of:
pure povidone iodine solution = 2 mL
This amount of pure povidone iodine solution is added or
diluted (most perhaps with water) to make a total of 1000 mL total solution,
therefore the new ratio is:
2:1000 povidone iodine solution
By dividing both sides by 2, this simplifies to
1:500 povidone iodine solution
Answer:
1:500
