Answer:
Molality stays nearly the same as its molarity
Explanation:
Let's make an example of this:
An aqueous solution of 1 mol of NaCl is diluited in a volume of 1L (A).
The same solution is diluited in a volume of 1L, but now we have 0.00001 moles of NaCl (B)
Solution A → Concentrated, [NaCl] = 1 M, 1 m
1L = 1kg
Solution B → Diluted, less concentration, Less molarity and molality.
Now, solution B has a volume of 5L, with 2 moles of solute while A, stays the same.
Molarity A = 1M
Molality A = 1m
Molarity B = 0.4 M
Molality B = 0.4 m
In conclussion, stays nearly the same as its molarity
The answer is A. Shrews eat crickets so if the the shrews were killed than there would be more crickets.
<u>Answer:</u> The thickness of metal sheet is 1.93 mm
<u>Explanation:</u>
The metals sheet is in the form of cuboid.
To calculate the width of the metal sheet for the given volume, we use the equation to calculate the volume of cuboid, which is:
where,
V = volume of metal sheet = 
l = length of metal sheet = 15.9 cm
b = width of metal sheet = 14.8 cm
h = height of metal sheet = ? cm
Putting values in above equation, we get:
Converting this thickness into millimeters, we use the conversion factor:
1 cm = 10 mm
So, 
Hence, the thickness of metal sheet is 1.93 mm
Answer:
chemical and physical changes
Ionic bounds are formed due to the electrostatic attraction between oppositely charged ions in a chemical compound.
The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
