How do i set this up using the dimensional analysis method

You want to start with years and end with kilograms of dog food.

1 yr → kg dog food

The sequence must be

1 yr → days → cups of food → grams of food → kilograms of food

At each step, you use a conversion factor (CF) to get the result you want.

Each CF must have

•on top the units of the result you want

•on the bottom, the units of the preceding term

Your sequence now becomes

Time = 1 yr × (no. of days/yr) × (no. of cups/day) × (g dog food/cup)

× (kg dog food/g dog food) = kg dog food

Notice that the denominator of a CF always cancels the units of the one before it.

Do you get something like 100 kg dog food?

asking the goog might u get an answer

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
