Answer: PV = nRT

A gas at STP... This means that the temperature is 0°C and pressure is 1 atm.

R is the gas constant which is 0.08206 L*atm/(K*mol)

Rearranging for volume

V = nRT/P

The temperature and number of moles are held constant. This means that this uses Boyle's Law. (The ideal gas law could be manipulated to give us this result when T and n are held constant.)

PV = k

where k is a constant.

This means that

P₁V₁ = k = P₂V₂

P₁V₁ = P₂V₂

(1 atm) * (1 L) = (2 atm) * V₂

V₂ = 0.5 L

The new volume of the gas is 0.5 L.

Consider the following reaction: 3Fe(s) + 4H₂O(g) ➞ Fe₃O₄(s) + 4H₂(g). To answer the following question: "How many moles of hot
Elodia [21]

Answer: 2

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}

\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles

3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)  

According to stoichiometry :

1 mole of Fe_3O_4 are produced by = 4 moles of H_2O

Thus 1.18 moles of Fe_3O_4 will be produced by=\frac{4}{1}\times 1.18=4.72moles  of H_2O

Mass of H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g

Thus 85.0  g of H_2O will be required and 2 steps are required to get the answer.

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation
Daniel [21]

  • The water in the pot becomes hotter as a result of heat transfer.

  • <em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

  • When a pot containing water  is  placed on the stove and  heat is applied with the burner, there is a flow of heat from the burner to the water.

  • Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water  will be energized as a result of the heat transfer until the boiling point  is  reached.

  • Energy transfer can take place in three form, this could be conduction, radiation or convention.

  • Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>

what actually is left over of water once it self ionizes? Like what exactly are the hydrogen and hydroxide ions? Do they remain
GrogVix [38]
The formula for the self ionization of water is 2H₂O(l)⇄H₃O⁺(aq)+OH⁻(aq)

The hydronium (H₃O⁺) is usually just referred to as a hydrogen ion or a proton (H⁺) and hydroxide (OH⁻) doesn't have another name that I am aware of.  These ions do stay in solution.  However the concentrations are really small and the equilibrium constant (K(w)) is 1×10⁻¹⁴.

I hope this helps.  Let me know if anything is unclear.
