What is the theoretical yield of waffles if you have 6 cups of flour, 9 eggs and 2 tbs of oil?

Yanka [14]

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. For this problem, the limiting reagent is oil.

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.

You should theoretically get 8 waffles.

Write a complete, balanced equation for the following reactions:

Sergeu [11.5K]

Answer:

Solution given:

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

Balanced chemical equation:

$\boxed{\bold{\green{Na_{2}CO_{2} +heat \rightarrow Na_{2}O +CO_{2}}}}$

when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide

f) chromium (III) hydroxide plus sulfuric acid

Balanced chemical equation:

$\boxed{\bold{\green{2Cr(OH)_{3}+ 3H_{2}SO_{4} → Cr_{2}(SO_{4})_{3} + 6H_{2}O}}}$

When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.

g) aluminum metal plus chlorine gas

$\boxed{\bold{\green{2Al(s) + 3Cl_2(g) \rightarrow 2AlCl_2 }}}$

When aluminum metal is added to chlorine gas Combination reaction takes place and forms aluminum chloride.
