High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.
I hope this helps you.
The boiling point of water is a characteristic physical property, because the water won't boil until it reaches the boiling point.
Answer:
The answer to your question is 0.04 M
Explanation:
Data
mass of Na₂SO₄ = 14.2 g
volume = 2.50 l
Molarity = ?
Process
1.- Calculate the molar mass of Na₂SO₄
Na₂SO₄ = (23 x 2) + (32 x 1) + (16 x 4) = 46 + 32 + 64 = 142 g
2.- Calculate the number of moles of Na₂SO₄
142 g of Na₂SO₄ ------------------- 1 mol
14.2 g of Na₂SO₄ ------------------ x
x = (14.2 x 1) / 142
x = 0.1 moles
3.- Calculate the molarity
Molarity = moles /volume
-Substitution
Molarity = 0.1 / 2.5
-Result
Molarity = 0.04
Well thats because things changed in science. Newtons law of gravity (which was all things that come up must come down) evolved once scientist figured out that in space things float around. Science always evolves weather it's in a year or a day, but if your asking about HOW it evolved, thats something different. Hope I'm helping you!
