I disagree through the student"s claim
From an easy chemistry, the rate of chemical reaction boosts with an boosted surface area.
You are watching: The highly reactive elements in group 7a are known for forming salts. what are they called?
This simply means that a powdered substance will react faster than a tiny pellet of the very same substance.
Let united state break this down further. The pellet has actually a smaller sized exposed surface ar per grain to the solvent, here is how. Imagine the powdered problem bunched up with each other to make the small pellet, grains at the center of the pellet is clogged by various other grains about it, and will take it time before it come in call with the solvent. Because that the powdered grains, each grain has a surface separately exposed to the solvent and can conveniently come in call with the solvent, taking much less time come react v the solvent.
Technically, a powdered substance has much more exposed surface ar area and also logically will certainly take a much shorter time for the reaction to be complete.

3) How plenty of moles of solute are liquified in 1.5 together of a 0.80 M solution? * 10 points
Molarity = moles/volume
to uncover the moles, you must multiply both political parties by volume
so, take it 1.5 together * 0.80 M
this equates to 1.2 :)

What’s the molar fixed of magnesium oxalate
Magnesium oxalate: MgC₂O₄
Mg: 1 x 24.305 = 24.305
C: 2 x 12.01 = 24.02
O: 4 x 16 = 64
The molar fixed of magnesium oxalate is 112.325 g/mol.
Hope this helps!

What is the thickness of water if you have actually 50.0 grams that water and also a volume the 50.0 millimeters
Density deserve to be found by separating the mass by the volume.
The massive of the water is 50.0 grams.
The volume the the water is 50.0 milliliters.
Substitute the values right into the formula.
The thickness of the water is 1.0 grams every milliliter. Also, remember that the density of pure water is always 1.0 g/mL or g/cm³
