Answer:
667.105ml
Explanation:
V1VP1 / V2P2
V2=V1P1 / P2
Pressure at S.T.P is 760
V2= 600×845/760
V2=667.105ml
Therefore V2 = 667.105ml approximately
Answer:
the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Answer:
Explanation:
Boyle believed that chemistry – the behavior of substances – could be explained through the motion of atoms, which in turn could be understood through mechanics – Galileo's mathematics of motion. Boyle was ultimately proved correct, because today we can understand chemistry mathematically, through quantum mechanics.
Answer:
0.4
Explanation:
Given data:
Number of moles of SrCl₂ consumed = ?
Mass of ZnCl₂ produced = 54 g
Solution:
Chemical equation:
ZnSO₄ + SrCl₂ → SrSO₄ + ZnCl₂
Number of moles of ZnCl₂:
Number of moles = mass/ molar mass
Number of moles = 54 g/136.3 g/mol
Number of moles = 0.4 mol
Now we will compare the moles of ZnCl₂ with SrCl₂ from balance chemical equation.
ZnCl₂ : SrCl₂
1 : 1
0.4 : 0.4
Thus when 54 g of ZnCl₂ produced 0.4 moles of SrCl₂ react.
<u>Answer:</u> The balanced chemical equation for the combustion of liquid ethanol is written below.
<u>Explanation:</u>
Combustion reactions are defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water. Heat is released during these reactions.
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The balanced chemical equation for the combustion of liquid ethanol follows:
By Stoichiometry of the reaction:
1 mole of liquid ethanol reacts with 3 moles of oxygen gas to produce 2 moles of carbon dioxide gas and 3 moles of water vapor.
Hence, the balanced chemical equation for the combustion of liquid ethanol is written above.
