Answer:
Element
Explanation:
Protons, Neutrons, and Electrons are all inside atoms . However an element cannot be present in a atom. Atoms make up an element.
Answer:
Explanation:
The formation of ammonia that occurred by the reaction of nitrogen and ammonia is expressed as:
⇄
where;
The reactants are:
Hydrogen and nitrogen
The product is ammonia.
For the reaction, the equilibrium constant can be expressed as:
From the equilibrium constant conditions, the formation of ammonia and its decomposition due to its reversible reaction back to hydrogen and nitrogen are equal. It implies that the rate of the forward reaction is also equal to that of the backward reaction.
Thus, during when equilibrium is obtained;
Hydrogen, Nitrogen, and Ammonia are present.
Answer:
I guess one mole. of mercury
Explanation:
because mercury is denser
Answer: P = 7.1 atm
Explanation: For this problem we will use Combined Gas Law to solve for the new pressure. But never forget to convert the unit of temperature to Kelvin.
P1V1 /T1 = P2V2/ T2, Derive for P2.
P2 = P1V1T2 / T1V2
= 1.00 atm ( 3.00 L ) ( 323 K) / 273 K ( 0.50 L )
= 7.1 atm
Cancel out the units of L and K and the unit remains is in atm.
