how many moles of carbon monoxide can be produced from 8 moles of carbon if carbon is the limiting reagent?
Mademuasel [1]

Answer:

8 moles of CO

Explanation:

To produce carbon monoxide we begin from C and O₂ as this reaction shows:

2C + O₂ → 2CO

Therefore, 2 moles of C can produce 2 moles of CO

If I have 8 moles of C, I must produce 8 moles of CO

Ratio is 1:1

The three chemical properties of a penny

Penny ( Pennies: plural; refer to a number of individual coins)

  • A chemical property of a substance is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

<h3>What is chemical property?</h3>

The chemical properties of a substance can be determined by performing experiments that use specific materials or processes with known characteristics.

The following are three chemical properties to consider when choosing an element to make coins:

  • Reactivity to water.

  • Reactivity to oxygen.

  • malleability.

It should malleable, ductile, and an extremely good conductor of both heat and electricity.

How are physical and<br>chemical changes different?​
astra-53 [7]
Physical changes happen when you do/mix something that can be reversed. Best example is ripping a paper, you can just tape it back together so it is just an observable thing that changes, which is a physical change. Chemical changes happen when you mix things and they make a new substance and can’t be reversed. The best example of this is the Statue of Liberty, which changed in color due to the chemical change between the oxygen and copper, which created a new substance (rust) which made it green instead of copper.
Sorry for the long answer but hope this helps!

How many molecules of CrCl₃ are produced when 2.89 moles of CuCl₂ react? *<br> 2Cr+3CuCI2-2CrCI3+3Cu
juin [17]

Explanation:

The reaction is CaCO

3

+2HCl→CaCl

2

+H

2

O+CO

2

.

Thus, 2 moles of HCl reacts with one mole of calcium carbonate to produce one mole each of calcium chloride, water and carbon dioxide respectively.

Hence, 3 moles of HCl will react with excess of calcium carbonate to produce 3×
