Balance the skeleton equations for the following reactions:

1) lithium(s) + gold (iii) chloride (aq) to lithium chloride (ag) + gold (s).

2) iron (s) + tin (iv) nitrate (aq) to iron (iii) nitrate (aq) + tin(s)

3) nickel(ii) cholride (s) + oxygen (g) to nickel (ii) oxide (s) + dichlorine pentoxide (g)

4) lithium chromate (aq) + barium chloride (aq) to lithium chloride (aq) + barium chromate (s)

! i missed the lesson! so much!

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
