Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
Explanation:
solids have particles that are closely packed to each other that they can barely move
The plant makes 3.50 × 10⁷ bearings per day
<em>Pounds of bearings</em> = 1 da × (4355 lb bearings/5 da) = 871.0 lb bearings
<em>Grams of bearings</em> = 871.0 lb bearings × (453.6 g bearings/1 lb bearings)
= 3.951 × 10⁵ g bearings
<em>No. of bearings</em> = 3.951 × 10⁵ g bearings × (1 bearing/0.0113 g bearing)
= 3.50 × 10⁷ bearings
Answer:
The equilibrium law
Explanation:
According to the equilibrium law , when of any of the reactants or the products in the reaction at an equilibrium state, is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of
Acetic acid (in excess) + ⇄ + water
is a reaction which involves the equilibrium. So to force the reaction towards the side of , one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.
Answer: Option (c) is the correct answer.
Explanation:
A state function is defined as the function of a system which relates to several state variables that depend only on the current equilibrium state of the system.
A state function does not depend on the path followed by the system to reach at its present state.
Enthalpy change is represented by and its value depends on state functions like U, P and V. Therefore, change in enthalpy is also a state function.
Value of these functions does not depend on the path taken to reach their values.
Therefore, we can conclude that the statement enthalpy is a state function, is true.
