Because the solid is soluble in water, it cannot be calcium fluoride.
This leaves us with either silver fluoride or potassium bromide, as both are soluble in water.
Upon addition of sodium sulfate, a white precipitate forms, confirming that the substance was silver fluoride as the precipitate are of silver sulfate.
A) The image is a drawing of the sun
B) Energy (light) from the sun
C) carbon dioxide
D) water
E) glucose
F) oxygen
Remember that the equation for photosynthesis is:
carbon dioxide + water -> (light energy) -> glucose + oxygen
<span>Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. </span>
When atoms share six electrons, they are joined by a double bond. (.5 points)
