Answer:
1.327 g Ag₂CrO₄
Explanation:
The reaction that takes place is:
- 2AgNO₃(aq) + K₂CrO₄(aq) → Ag₂CrO₄(s) + 2KNO₃(aq)
First we need to <em>identify the limiting reactant</em>:
We have:
- 0.20 M * 50.0 mL = 10 mmol of AgNO₃
- 0.10 M * 40.0 mL = 4 mmol of K₂CrO₄
If 4 mmol of K₂CrO₄ were to react completely, it would require (4*2) 8 mmol of AgNO₃. There's more than 8 mmol of AgNO₃ so AgNO₃ is the excess reactant. <em><u>That makes K₂CrO₄ the limiting reactant</u></em>.
Now we <u>calculate the mass of Ag₂CrO₄ formed</u>, using the <em>limiting reactant</em>:
- 4 mmol K₂CrO₄ *
= 1326.92 mg Ag₂CrO₄
- 1326.92 mg / 1000 = 1.327 g Ag₂CrO₄
#1 The Correct Answer is D
<span>D) The Distance Traveled by The Wave During One Full Cycle.
Ex. frequency, wavelength, amplitude and wave speed. Amplitude is measured in metres (m). The greater the amplitude of a wave then the more energy it is carrying. The wavelength, λ, of a wave is the distance from any point on one wave to the same point on the next wave along.
(The symbol is a Greek letter, 'lambda'.)
#2 The Correct Answer is B

Ex.Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. </span>
The recipe for an omelet are:
<u>Ingredients</u>
- 1 Egg
- Salt and pepper ( 1 tablespoon )
- Butter ( 1 tablespoon )
<u>Recipe:</u>
- Turn on the heat and place a pan on it.
- Add butter to the pan.
- Crack the egg and whisk it properly.
- Add the whisked omelet onto the pan and stir.
- Add salt and pepper.
<h3>How to illustrate the information?</h3>
When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.
When we add butter to the pan, then the temperature of the pan was more than that of the butter.
Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.
When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.
These are the chemical reactions depicted.

Answer is: There are more reactants and one product of the reaction. The reactants may be elements or compounds. The product is always a compound.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
For example, balanced chemical reaction: Ba + F₂ → BaF₂.
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
Second chemical reaction: CaO(s) + H₂O(l) → Ca(OH)₂(aq).
One molecule is produced from two molecules.
