Answer : The age of the artifact is,
Explanation :
Half-life = 5715 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time taken to decay.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = time taken by sample = ?
a = initial activity of the reactant = 58.2 counts per minute
a - x = activity left after decay process = 42.8 counts per minute
Now put all the given values in above equation, we get
Therefore, the age of the artifact is,
hey there!:
As El Tation is located at higher altitude than Old Faithful, the atmospheric pressure would be less at Ei Tatio.
Due to low pressure, the boiling point of water will be reduced at El Tatio. Hence, at lower temperature than Old Faithful, geysers will erupt at El Tatio due to depression of boiling point at reduced atmospheric pressure.
Hope this helps!
1) Calculate the number of moles of Cu SO4 . 5H20 by dividing the specified mass by the molar mass.
2) The ratio of production given by the equation is 1 mol of Cu SO4 . 5 H2O to 1 mol of Cu SO4=> 1:1, meaning that the number of moles of Cu SO4 produced is the same number of moles of Cu SO4.5H20 heated.
3) Finally mutiply the number of moles of Cu SO4 by its molar mass and there you have the mass of Cu SO4 produced.

The number that will be multiplied by 588 to get one's weight in Newtons is 2.5 considering that the mass of the individual is 60kg.
<h3>How to calculate weight?</h3>
Weight is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).
The weight of an object can be calculated by multiplying the mass of the object by acceleration due to gravity of the location.
According to this question, we would consider an individual with a mass of 60kg. The acceleration due to gravity on Jupiter is 24.5 m/s².
Weight = 60kg × 24.5 m/s² = 1470N
This means that the number to be multiplied by 588 to get weight of 1470N is 2.5.

All you have to do is multiply by two, since calcium chloride has the chem. formula, CaCl2. For every 1 mole of CaCl2, you'll have 2 mole of chloride ions in solution.
