Answer:

In this chemical reaction, which is considered irreversible, that is why the reaction arrow is ONE and unidirectional and not two in opposite directions, which means reversibility of the reaction.

In summary, if we look closely at the reaction, we observe that the stoichiometric values are balanced in the reaction, therefore there is THE SAME AMOUNT OF REAGENTS AS PRODUCTS.

This phenomenon has to be met in ALL CHEMICAL REACTIONS, the stoichiometric balance is essential for this reaction to be well expressed.

Why is stoichiometric balance so important? Why we indicate that we have the same amount of reagents as products, means that NOTHING IS LOST, EVERYTHING IS TRANSFORMED in the matter of the organic compounds that reacted.

Explanation:

Although if we observe the stoichiometric values well they are not correct with respect to oxygen, therefore it would be necessary to correct that in the chemical reaction, but above we briefly explain why the balancing of the reactions and the relationship they have with the conservation of the mass.

The law of conservation of mass indicates that mass is never lost, but is transformed, like energy, considering that it happens in terrestrial life.

I NEED HELP PLEASE, THANKS!
ira [324]

Answer:

About 0.652

Explanation:

Because the reaction is balanced, we can go straight to the next step. The molar mass of potassium is about 39.098, while the molar mass of hydrogen gas is 2 and the molar mass of water is 18. Therefore, 25.5g of potassium would be about 0.652 moles, and 220 grams of water would be about 12.222 moles, making potassium the limiting reactant. Since there is a single unit of each compound on both sides of the equation, there would be an equal amount of moles of potassium and hydrogen, and therefore about 0.652 moles of hydrogen gas would be produced. Hope this helps!

Calculate the molarity and normality of 5.7 g of Ca(OH)2 in 450 mL of solution.
Kisachek [45]
  The  molarity   and  normality  of  5.7 g  of  Ca(OH)2   in  450ml  0f    solution  is  calculated  as  follows

molarity  =  moles/volume in  liters
moles  =mass/molar  mass
=  5.7g/74g/mol  =  0.077moles
molarity =  0.077/450  x1000= 0.17M

Normality =  equivalent  point  x molarity
equivalent  point  of Ca(OH)2  is  2   since  it has  two  Hydrogen  atom

normality  is therefore =  0.17  x2 = 0.34 N
