Explanation:
We are given the following diagram.
In this diagram we can see how the energy in the reaction changes over time. The energy of the products is greater than the energy of the reactants. That means that the products have won some energy. That represents an endothermic reaction where the reactants absorb energy from the surrounding to form the products.
Answer: D. Endothermic reaction.
The correct answer is oil
Answer:
Ideal gas constant is a universal constant used for all gases
Explanation:
In Ideal Gases Law, the Ideal gas constant is called R.
It can also be used in Van der Waals equation or, in thermodynamic equations.
R = 0.082 l.atm/mol.K
It is related to the Boltzmann constant, a number that links energy units with temperature units.
Answer: E. 78%
Explanation:
Diborane (B2H6), a chemical compound made up of approximately 78% Boron and 22% Hydrogen.
