Answer:
1. C 2. B 3. A
Explanation:
1. Gay- Lussac law, states that as along as the volume is kept constant, the pressure of a fixed mass of gas is directly proportional to the temperature.
The properties it compares is; (c.) Pressure and temperature
2. Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.
It therefore compares; (b.) Pressure and volume
3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.
It therefore compares; (a.) Volume and moles
Answer:
C
Explanation:
The molecule has 8 carbon atoms joined by 7 C-C bonds.
The first two diagrams show 6 carbon atoms, not 8.
The last two diagrams show line segments representing C-C bonds. Only choice C shows 7 such segments.
The appropriate choice is C.
53.14 grams of Zn
will be produced from 26.0 g of Zn and 42.0 g of HCl.
Explanation:
Balanced chemical reaction:
Zn + 2 HCl ⇒ Zn + 
data given:
mass of Zn = 26 grams
mass of HCl = 42 grams
mass of Zn = ?
here in the reaction Zn is the limiting reagent so mass of
Zn formed will be determined by it.
atomic mass of zinc =65.38 grams/mole
number of moles = 
putting the values in the above equation:
number of moles of zinc = 
number of moles of zinc = 0.39 moles
From the balanced reaction it is seen that
1 mole of Zn produced 1 mole of Zn
0.39 moles will produce x moles of Zn
0.39 moles of Zn (atomic mass of Zn = 65.38 grams/mole)
mass = atomic mass x number of moles
= 0.39 x 136.28
= 53.14 grams
53.14 grams of Zn is formed
Answer:
160.18 grams
Explanation:
You find the molar mass which is 68.16 g/mol and multiply that by the number of moles present.
Answer:
Remove the already produced water and allow the reaction to reach equilibrium again.
Explanation:
<em>According to Le Chatelier principle, when a reaction is in equilibrium and one of the factors that influence the rate of reaction is altered, the equilibrium will shift so as to annul the effects of the change.</em>
If the product is continuously being removed from a reaction that is in equilibrium, more product will continued to be formed in another to annul the effect of reduction in the concentration of product.
Hence, in order to maximize production of water in the reaction, the product (water) needs to be removed and the reaction allowed to reach equilibrium again.
