Answer:
E. Brønsted-Lowry and Lewis bases.
Explanation:
An Arrhenius base is a molecule that when dissolved in water will break down to yield an OH- or hydroxide in solution.
Bronsted-Lowry base refers to any atom or ion capable of accepting or bonding to a free proton in solution.
Lewis Base is an electron pair donor. Also, it is a molecule that attacks another atom with its eldctron is an electron pair donor and a Lewis Base.
So according to the Lewis acid-base concept, amines can donate an electron pair, so they are Lewis bases. Also, Brønsted-Lowry bases can accept a proton to form substituted ammonium ions. So, amines are bases according to both the Lewis and the Brønsted-Lowry base.

Hello there!
In this case, according to the given atoms of aluminum, it is possible for us to calculate the mass via the Avogadro's number and its atomic mass of 27.0 g/mol:
Noe, given the density of the Al, we can calculate the volume as shown below:
Best regards!
Answer:
32.7 L of H₂
Explanation:
We'll begin by calculating the number of mole in 95 g of Zn. This can be obtained as follow:
Mass of Zn = 95 g
Molar mass of Zn = 65 g/mol
Mole of Zn =?
Mole = mass /Molar mass
Mole of Zn = 95/65
Mole of Zn = 1.46 mole
Next, we shall determine the number of mole of H₂ produced by the reaction of 95 g (i.e 1.46 mole) of Zn. This can be obtained as illustrated below:
Zn + H₂SO₄ —> ZnSO₄ + H₂
From the balanced equation above,
1 mole of Zn reacted to produce 1 mole of H₂.
Therefore, 1.46 mole of Zn will also react to produce 1.46 mole of H₂.
Finally, we shall determine the volume of H₂ obtained at STP. This can be obtained as follow:
1 mole of H₂ = 22.4 L at STP.
Therefore,
1.46 mole of H₂ = 1.46 × 22.4
1.46 mole of H₂ = 32.7 L at STP
Thus, 32.7 L of H₂ were obtained from the reaction.
