<span>The molecular formula for Copper(II) Sulfate is CuSO4. 1 mole is equal to 1 moles Copper(II) Sulfate, or 159.6086 grams.I hope this is right </span>
Answer:
its speeding up but not at a constant speed
Explanation:
Answer:
1.
Solid: A, B, and C.
Liquid: D and E.
Gas: F.
2.
Into liquid on warm day (37 °C): D and C.
Into a liquid only when heated slightly: C and E.
From liquid to solid readily when placed into a freezer (0 °C): D.
Explanation:
Hello!
In this case, since the melting point is the temperature at which a substance change from solid to liquid and the boiling point from liquid to gas, we understand that substance at a temperature below the melting point is solid, whereas above are liquid; moreover, below the boiling point they are liquid and above gaseous.
In such a way, we have:
1.
Solid: A, B, and C.
Liquid: D and E.
Gas: F.
2.
Into liquid on warm day (37 °C): D and C.
Into a liquid only when heated slightly: C and E.
From liquid to solid readily when placed into a freezer (0 °C): D.

Trace fossils may consist of impressions made on or in the substrate by an organism: for example, burrows, borings (bioerosion), urolites (erosion caused by evacuation of liquid wastes), footprints and feeding marks, and root cavities.
First we look at the chemical reaction:
2 Na + Cl₂ → 2 NaCl
Now we should see which is the limiting reagent, so we construct the following reasoning:
if 2 moles of Na reacts with 1 mole of Cl₂
then 2.4 moles of Na reacts with X moles of Cl₂
X = (2.4 × 1) / 2 = 1.2 mole of Cl₂ (way lower that the available quantity of chlorine).
So the limiting reagent is sodium, and from here we can calculate the number of moles of NaCl produced.
if 2 moles of Na produces 2 moles of NaCl
then 2.4 moles of Na produces Y moles of NaCl
Y = (2.4 × 2) / 2 = 2.4 moles fo NaCl (sodium chloride)
