The overall charge of the given compound of potassium and Arsenic is zero (0).
<h3>What is the charge of an atom?</h3>
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. When the number of protons exceed the number of electrons, the atom will positively charged and it will be negatively charged if the number of electrons exceed the number of protons.
For the given compound;
- KAs; As (Arsenic = -3) + K (potassium = +3)
- KAs overall charge = -3 + 3 = 0
Thus, the overall charge of the given compound of potassium and Arsenic is zero (0).

Answer:
D. formation of zinc from zinc sulphide
Explanation:
A redox reaction could be explained as an artificial reaction in which electrons are moved between two reactants partaking in it. This substitution of electrons can be recognized by examining the variations in the oxidation states of the reacting classes. The generation of hydrogen fluoride is an illustration of a redox reaction. We can crack the reaction down to investigate the oxidation and loss of reactants.
Answer:
the protein capsid of naked viruses is less susceptible to environmental . condition
Explanation:
because the envelop is made in part of phospholipids. once the envelop is lysed ,the virus loses its functiovnal receptors and still able to infect susceptible cells.
