Answer:
Explanation:
From the question we are told that:
Volume of hydrogen
Temperature
Pressure of water
Let
STP(Standard Temperature and pressure)
Generally the equation for ideal gas is mathematically given by
Therefore
(at STP(Standard Temperature and pressure))
Answer:
Surface mining (also known as "strip mining") has the potential to significantly erode soil fertility, pollute waters, deplete underground water sources, scar or altar the landscape, damage roads, houses, and other buildings, and kill wildlife.
Answer: The metal is Calcium.
Explanation:
To calculate the specific heat of substance during the reaction.
where,
q = heat absorbed = 789.75 J
c = specific heat of metal = ?
m = mass of substance = 18.0 g
= final temperature - initial temperature =
Now put all the given values in the above formula, we get:
As specific heat is characteristic of each metal and thus the metal is calcium which has specific heat of

Answer:
<em>6960000 Nickel atoms</em>
<em></em>
Explanation:
radius = 125 pm = 125 x 10^-12 m
diameter of each atom = 125 pm x 2 = 250 pm = 250 x 10^-12 m
span of distance to be achieved = 1.74 mm = 1.74 x 10^-3 m
number of nickel atoms = (1.74 x 10^-3 m)/(250 x 10^-12 m) = <em>6960000 Nickel atoms</em>
