Answer:
Al(OH)₃ + OH⁻ → Al(OH)₄⁻
The compound is called hydroxoaluminate.
Explanation:
Aluminiun Hydroxide → Al(OH)₃
NaOH → Sodium hydroxide.
The Al(OH)₃ is an amphoteric compound, while the NaOH is a strong base. When they react, we may think that, fist of all, the base can dissociate: NaOH → Na⁺ + OH⁻
So the Al(OH)₃ will be a Lewis acid, as it can donate a pair of e⁻
Al(OH)₃ + OH⁻ → Al(OH)₄⁻
Assuming that the change of volumen was done at constant pressure and the quantity of gas did not change, you use Charles' Law of gases, which is valid for ideal gases:
V / T = constant => V1 / T1 = V2 / T2 => V1 = [V2 / T2] * T1.
Now plug in the numbers ,where T1 and T2 have to be in absolute scale.
T1 = 38.1 + 273.15 K = 311.25K
T2 = 15.0 + 273.15 K = 288.15K
V1 = 4.5L * 311.25K / 288.15 K = 4.86L.
Answer: 4.86
Answer:
Water moves into the cell
Explanation:
As shown in the question above, the cell is high in glucose and placed in a glass filled with water. This cell has a semi permeable membrane that allows only water to pass through, as the concentration of water within the cell is low, the cell will attempt to strike a balance with the medium it is inserted into. For this reason, what is likely to happen is the passage of water from the most concentrated to the least concentrated medium, that is, the water will pass from the cup to the cell.
water moves into the cell through osmosis.during osmosis water moves from a region of low concentration of solute to a region of high concentration of solute.the glucose introduced into the cell makes it more concentrated.
In this case the cell is hypertonic and water would enter into the cell through the semi permeable membrane.this membrane allows water to pass through but not glucose.this movement of water into the cell causes the cell to become turgid.
Answer:
strongest oxidizing agent: 
weakest oxidizing agent: 
strongest reducing agent: Y
weakest reducing agent: X
will oxidize Z
Explanation:
The higher the reduction potential of a species, higher will be the tendency to consume electrons from another species. Hence higher will be the oxidizing power of it's oxidized form and lower will be the reducing power of it's reduced form.
Alternatively, higher reduction potential value suggests that the oxidized form of the species acts as a stronger oxidizing agent and the reduced form of the species acts as a weaker reducing agent.
Order of reduction potential:
So, strongest oxidizing agent:
weakest oxidizing agent:
strongest reducing agent: Y
weakest reducing agent: X
As reduction potential of the half cell 
is higher than the reduction potential of the half cell 
therefore will oxidize Z into 
and itself gets converted into X.
Answer:
0.15 moles of sodium hydroxide are in the solution.
Explanation:
Molarity is a unit for expressing concentration of solutions. Molarity is defined as the number of moles of solute per liter of solution.
The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution:
Molarity is expressed in units (
).
So, a molarity of 0.750 M indicates that 0.750 moles are present in 1 L of solution. Then the following rule of three can be applied: if in 1000 mL (being 1 L = 1000 mL) there are 0.750 moles, in 200 mL how many moles are there?
amount of moles=0.15
<u><em>
0.15 moles of sodium hydroxide are in the solution.</em></u>
