Determine how much energy is needed to change 50 g of liquid water at 100°C to steam.
marin [14]

Answer:

Q=113,000J

Explanation:

Hello there!

In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:

Q=m*\Delta _{vap}H

Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.

Q=50*2259.36 J/g\\\\Q=113,000J

Which is positive due to the necessity of heat.

Regards!

Answer:

\boxed{It\ will\ shift\ to\ create\ less\ of\ substance\ A}

Explanation:

If the concentration of any substance A in a dynamic equilibrium increases, The equilibrium will be  shifted to its opposite side so that Substance A can be created less and the substance opposite to A can be created more so that a "dynamic equilibrium" can again be established.

describe how the current modern atomic theory and model differs from the model jj Thompson proposed ?
myrzilka [38]
J.J Thompson’s model shows a sphere with electrons that are moving around freely. However, Thompson’s model does not show protons or neutrons. The model that we have today gives a clearer structure showing protons, neutrons, and electrons inside an atom.

The first step in the reaction of Alka–Seltzer with stomach acid consists of one mole of sodium bicarbonate (NaHCO3) reacting wi
Gnesinka [82]

Answer: 5 moles of  H_2CO_3 can be produced from 5 mol NaHCO3 and 9 mol HCl.

Explanation:

The balanced chemical reaction is:

NaHCO_3+HCl\rightarrow H_2CO_3+NaCl

According to stoichiometry :

1 mole of NaHCO_3 use 1 mole of HCl

Thus 5 moles of NaHCO_3 use=\frac{1}{1}\times 5=5moles  of HCl

Thus NaHCO_3 is the limiting reagent as it limits the formation of product and HCl is the excess reagent.

As 1 mole of NaHCO_3 give = 1 mole of H_2CO_3

Thus 5 moles of NaHCO_3 give =\frac{1}{1}\times 5=5moles  of H_2CO_3

5 moles of  H_2CO_3 can be produced from 5 mol NaHCO_3 and 9 mol HCl.
