Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
Answer:
12.7g of Cu
Explanation:
First let us generate a balanced equation for the reaction. This is illustrated below:
Zn + CuSO4 —> ZnSO4 + Cu
Molar Mass of Cu = 63.5g/mol
Molar Mass of CuSO4 = 63.5 + 32 + (16x4) = 63.5 + 32 + 64 = 159.5g/mol
From the equation,
159.5g of CuSO4 produced 63.5g of Cu.
Therefore, 31.9g of CuSO4 will produce = (31.9 x 63.5) / 159.5 = 12.7g of Cu
These are electron dot diagrams.
They use dots arount the symbol of an atom to represent its <em>valence electron</em>s.
You will also see them called <em>Lewis dot symbols</em> or <em>Lewis diagrams</em>.
Pressure of the ideal gas=505.7kPa
Given:
No of moles=0.907mole
Temperature of the gas=
Volume of the gas=4.25L
To find:
Pressure of the gas
<u>Step by Step Explanation:
</u>
Solution:
According to the ideal gas equation
and from this pressure is derived as
Where P=Pressure of the gas
V=Volume of the gas=4.25L
n=No of the moles=0.907mole
R=Gas constant=8.314
T=Temperature of the gas= =273+12=285K
Substitute these known values in the above equation we get
P=505.7kPa
Result:
Thus the pressure of the ideal gas is 505.7kPa
