Answer:
8 waffles
Explanation:
First, find the limiting reagent. Divide the amount you have by the amount that is needed. The smallest number is the limiting reagent. <u>For this problem, the limiting reagent is oil.</u>
6 cups of flour/2 cups of flour = 3
9 eggs/3 eggs = 3 2 tbsp of oil/1 tbsp of oil = 2
This means that we can double the recipe since we have enough of each ingredient to make two batches. Multiply the entire equation by 2. This should give you 4 cups of flour + 6 eggs + 2 tbsp of oil ==> 8 waffles.
<u>You should theoretically get 8 waffles.</u>
BaCl2 reacts with KOH forming KCl which is a salt and Ba(OH)2 which is the precipitate.
The initial UNBALANCED equation expressing this reaction would be:
BaCl2 + KOH .............> KCl + Ba(OH)2
Now, we need to balance this equation:
we have two moles of Cl as reactants and one mole only as product. Therefore, we will multiply the KCl in the product by 2 and the KOH in the reactants by 2.
This will balance the equation as follows:
BaCl2 + 2KOH ......> 2KCl + Ba(OH)2
Noticing this equation, we will find that:
The precipitate was formed due to the combination of the Ba2+ ion with 2 OH- ions as follows:
Ba2+ + OH- ............> Ba(OH)2
Yes. That is a mixture. You are allowed to remove the sugar because there is sugar molecules in the water.
<span>2CO(g) + 1O2(g) ---> 2CO2(g)
2 mol CO 1 mol O2 2 mol CO2
1 mole O2 to 2 moles CO2, or
