☁️ Answer ☁️
Option 1: When dissolved, sugar molecules have more opportunities to bond with positive-negative water molecules. Therefore, sugar dissolves faster than salt, because its component molecules are more soluble in water.
❤️
Option 2: Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. It’s almost the same.
Hope it helps.
Have a nice day!~ ￣▽￣❤️
Answer:
827 mL
Explanation:
To answer this question we use the <em>definition of Molarity</em>:
Molarity = mol / L
[Cl⁻] = mol Cl⁻ / L
Now we calculate the moles of Cl⁻ present in 42.0 g of MgCl₂⋅6H₂O:
Molar mass of MgCl₂⋅6H₂O = 24.3 + 2*35.45 + 6*18 = 203.2 g/mol
moles of Cl⁻ = 42.0 g MgCl₂⋅6H₂O ÷ 203.2 g/mol * 
= 0.4134 mol Cl⁻
Finally we use the definition of molarity to calculate the volume:
0.500 M = 0.4134 mol Cl⁻ / xL
xL = 0.827 L = 827 mL

Explanation:
I just had this question on my test
Answer:
D. The plates are different in size from the landmasses.
Explanation:
- The tectonic plates that are also called lithospheric plates are very massive and irregular-shaped rocks that are composed of both the continental and the oceanic lithosphere and they may vary from a few hundred to thousands of square km.
<em>Answer:</em>
- Pivalic acid forms a strong conjugate base.
<em>Explanation:</em>
- Strong acid has weak conjugate base
- Weak acid has strong conjugate base
As in this case, pivalic acid is weak acid (Due to electron donating effect of <em>tert.</em> butyl group) having pka value of 5.0 , so its conjugate base will be strong as compare to formic acid which is stronger acid.
<em>Summary: </em>
- As pivalic acid is weak acid as compare to formic acid, so its conjugate base will be strong and vice versa.
