Answer:
15 moles
Explanation:
The rates of the forward and reverse reactions are unequal.
The concentrations of the products and reactants do not change.
The forward reaction stops at 500 K.
The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.
A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.
Answer:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

Answer:
Second graph is more reactive.
Explanation:
I just did the lesson myself, chose the first graph, and obviously got it wrong.
Therefore I can tell you with 100% certainty that the correct answer is graph #2 in this case. Hope this helps.
B. 36.5 mL
C. 36.0 mL
D. 38.0 mL

The given formula MgSO₄•7H₂O contains 11 oxygen atoms. Therefore, option (1) is correct.
A chemical formula of a compound describes the chemical proportions of each element in a chemical compound or molecule. The chemical formula of a molecule can be written with help of the chemical symbols of elements, numbers (subscripts), and some other symbols, such as brackets, dashes, plus (+) and minus (−) signs, and commas.
A chemical formula contains no words but contains certain simple chemical structures but not complete structures. These formulae must be limited in power than chemical names and structural formulae.
We have two types of formulas in chemistry one empirical formula and the other molecular formula. In the formula MgSO₄•7H₂O, the four oxygen atoms in MgSO₄ and seven from 7 water molcules.
The number of oxygen atoms in the given formula MgSO₄•7H₂O is equal to (4 + 7) = 11 atoms.
