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.
A. the transition elements
Answer:
B
Explanation:
Because a ball falling down is a good strong force
<h2>Relative Humidity</h2>
Explanation:
- Humidity is the amount of moisture content present in the atmosphere.
Humidity is of two types:
- Absolute humidity.
- Relative humidity.
- Absolute humidity is the ratio of the amount of moisture content in the air to the unit volume of the air.
- Relative humidity can be derived as the ratio of moisture content in the air to the maximum amount of moisture that the air constitutes.
- Hence, the required answer is Relative humidity.
C) 3 Moles
This is because of the molecular structure shown in the image
