Some of the salt would settle out. When the water was heated, it was able to absorb more salt than usual. This is known as super saturation. When the water is frozen it cannot hold as much salt, so some of it has to come out.
Answer:
The answer to your question is letter B. 9
Explanation:
Unbalanced reaction
Al₂(SO₄)₃ + Ca(OH)₂ ⇒ Al(OH)₃ + CaSO₄
Reactants Elements Products
2 Al 1
3 S 1
14 O 7
1 Ca 1
2 H 3
Balanced reaction
Al₂(SO₄)₃ + 3Ca(OH)₂ ⇒ 2Al(OH)₃ + 3CaSO₄
Reactants Elements Products
2 Al 2
3 S 3
18 O 18
3 Ca 3
6 H 6
The sum of the coefficients is 1 + 3+ 2+ 3 = 9
Colder- moves slower
warmer- moves faster
changes state:
solid to gas- warmer
gas to solid- colder
something like that
Since there is one carbon with 4 Fluorines attached to it, and both compounds are no metals, we use the covalent method for naming,
Here we ignore the prefix for the first element if it is 1. Mono. Then pay attention to the second one, it would be tetra, because tetra means 4. Here there are 4 fluorines.
Drop ine and place ide
CF4 = carbon tetrafluoride.
The contribution to the nature of light-
Thomas Young - wave nature of light (double-slit experiment)
Max Planck - E = hv
Albert Einstein - a quantum theory of light
Thomas Young proposed the most important double-slit experiment which shows that light acts like a wave and shows the pattern of interferences.
Max Planck proposed that light is proportional to frequency. He gave the equation, E = hv, where E is the energy of light, h is Planck's constant, and v is the frequency.
Albert Einstein proposed the quantum theory of light. He determined that light exists in discrete quanta of energy called photons.
