Answer:
Explanation:
Mass of copper = 50 g
Molar mass of copper = 63.5 g/mol
The formula for the calculation of moles is shown below:
Thus,
Also,
1 atom of neutral copper contains 29 electrons
1 mole of neutral copper contains electrons
0.7874 moles of neutral copper contains electrons
0.7874 moles of neutral copper contains electrons.
Given, Charge = 1.5 μC
1 μ = 10⁻⁶ C
So, Charge on the copper =
Charge on 1 electron =
Thus, number of electrons = Total charge / Charge on one electron
Thus,
Fraction :
Answer:
B. The value of q is positive
Explanation:
Bronsted Lowry base is the species that accepts or acquires protons from other species of the reaction. is the Bronsted-Lowry base.
<h3>What is a Bronsted-Lowry base?</h3>
In an acid-base reaction, the element or the compound capable of obtaining a proton or a hydrogen atom is called a Bronsted-Lowry base.
According to the theory, the base will accept proton and acid will donate an electron. The reaction of the acid and base is shown as,
From the reaction, it can be said that bicarbonate is the Bronsted-Lowry base as the number of hydrogen or protons are increasing in the product.
Therefore, option b. is the Bronsted-Lowry base.
