The general gas law equation that is formed by combining the three laws of Boyle, Charle and Guy Lussac is written as:
(PV/T)1 = (PV/T)2
STP conditions means that T= 273 kelvin and P = 1 atmospheric pressure
Based on the above rule, we calculate V2 as follows:
(4.25*55)/500 = (1*V)/273
V2 = 127.599 liters
Extra notes:
Boyles law: volume and pressure of a certain mass of gas are inversely proportional provided that the temperature is constant
Charle's law: volume and temperature of a certain mass of gas are directly proportional provided that the pressure is constant
Guy Lussac's law: pressure and temperature of a certain mass of gas are directly proportional provided that the volume is constant
Answer:
an anion
Explanation:
since it lost a proton..it now has 3 protons and four electrons and possesses a minus charge since it is no longer neutrally charged..this minus charge makes it an anion
Answer:
Moles
Explanation:
Mole is used to describes the amount of matter. The one mole of every substance have different mass, because every matter has different mass. The one mole of substance is equal to the molar mass of that substance.
The molar mass of substance is the mass in gram in one mole and it is represented by g/mol.
For example:
The molar mass of oxygen is 16 g/mol. If we take 16 g of oxygen we would say we taken one mole of oxygen. If we take 32 g of oxygen than it is describe as two mole of oxygen.
Consider the following reaction:
2H₂ + O₂ → 2H₂O
In this reaction two mole of hydrogen gas combine with one mole of oxygen and produce two moles of water.
The reaction for magnesium iodide when put into water is as below
MgI2(s) → Mg^2+(aq) + 2I^-(aq)
when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .
