Briefly explain why an unbalanced chemical equation cannot fully describe a reaction?
zubka84 [21]

From the conservation of mass, matter is not created nor destroyed. So ponder it this way, for example I put one piece of toast in a toaster, but when it is done I had two pieces, that makes no sense right? Same thing with a chemical reaction but in molecular terms, all things must stay constant. If you put a convinced amount you have to get that quantity back, not less or not more in broad terms.

10. A small helium tank claims to be able to fill 30 balloons to a volume of 3.15 L
Sindrei [870]

Taking into account the Boyle's law, 3.377 L of helium the tank will be able to  produce at a pressure of 94.2 kPa.

The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.

Boyle's law is one of the gas laws that relates the volume and pressure of a certain quantity of gas kept at constant temperature.

This law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. That is, if the pressure increases, the volume decreases; while if the pressure decreases, the volume increases.

Mathematically, Boyle's law states that the product of pressure and volume is constant:

P×V= k

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

P1× V1= P2×V2

In this case, you know:

  • P1= 101 kPa
  • V1= 3.15 L
  • P2= 94.2 kPa
  • V2= ?

Replacing in Boyle's law:

101 kPa× 3.15 L= 94.2 kPa× V2

Solving:

V2=\frac{101 kPa x3.15 L}{94.2 kPa}

<u><em>V2= 3.377 L</em></u>

In summary, 3.377 L of helium the tank will be able to  produce at a pressure of 94.2 kPa.

In a Lewis structure, why must pairs of unshared of lone pairs if dots be placed around the outside of some of the atoms
Maksim231197 [3]

Answer:

In a Lewis symbol, the symbol for the element is used to represent the atom and its core electrons. Dots placed around the atom are used to indicate the valence electrons. ... In 1916, Gilbert Newton Lewis, an American chemist, suggested that molecules were formed when atoms shared pairs of outer electrons.
