Answer: Yes
Explanation:
Yes, i would invest in this idea, Because the procedure looks very lucrative. Because the initial extraction of the energy from the ground requires no fossil fuel to keep the device running or in operation, rather the heat extracted would be used to heat a heat pump which would boil into steam and in turn used to drive a or power a steam engine.

Explanation:
Answer : The energy change for the reaction is CsCl is, 95 KJ/mole
Explanation :
The steps involved in the formation of :
(1) Conversion of gaseous potassium atoms into gaseous potassium ions.
= ionization energy of potassium = 419 kJ/mol
(2) Conversion of gaseous bromine atoms into gaseous bromine ions.
= electron affinity energy of bromine = -324 kJ/mol
The overall reaction will be:
To calculate the overall energy change the expression used is:
Now put all the given values in this equation, we get:
Therefore, the energy change for the reaction is CsCl is, 95 KJ/mole
The simplest ratio of elements in a molecule is called as Empirical Formula.
For Example,
Empirical formula of Benzene is CH
Empirical formula of Formaldehyde is CH₂O
Calculation of Empirical Formula:
Empirical formula can be calculated from Molecular formula by dividing the molecular formula with such number that all number of elements in molecular formula gets the lowest and simplest number.
Like Benzene Molecular formula is C₆H₆, when it is divided by 6 we get C₁H₁ or simply CH.
So, for acetic acid having molecular formula C₂H₄O₂ we can only divide it with 2 to have the simplest form, i.e.
C₂H₄O₂ ÷ 2 = C₁H₂O₁ or CH₂O
Result:
So the ratio of elements in acetic acid is
C : H : O
1 : 2 : 1
To find the mass in grams of Selenium, you use the moles you have and multiply it by the molar mass.
5489 Moles Se * (79g Se / 1mole Se) =433631g of Se
