photosynthesis: the process when plants make their own food using sunlight
it's 3 dollars per 12 eggs so 3/12
simplify 3/12 by dividing both numbers by 3 so you get 1/4
you should know what 1/4 of a dollar is
or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs
Answer:
C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.
The unbalanced reaction:
I₂ + O₂ -----> I₄O₉
<u>Reactants</u>: 2 iodine, 2 oxygen
<u>Products</u>: 4 iodine, 9 oxygen
The balanced equation:
4 I₂ + 9 O₂ -----> 2 I₄O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
2,8,1
It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)
