The following types of bonds exists between the listed atoms;
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic
<h3>What is a polar covalent bonds?</h3>
A bond is polar covalent when the electronegativity difference between the bonding atoms is above that found in a nonpolar covalent bond. Now we shall see the types of bonds between these atoms.
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic

Define the problem
Explanation:
The first step in a scientific investigation is to define the problem at hand. Definition of a scientific problem makes a scientific investigations possible.
- When preliminary observations are made about a phenomenon. A lot of questions as to why such things occur will arise.
- From the question, we can state the problem and the likely causes.
- The first portal in an inquiry is problem definition.
- This would them lead to the formulation of a hypothesis which contains problem statement and likely causes.
- The hypothesis leads to the design of an experiment from which investigations using experiments can be done.
- The data from the experiments are collected and analyzed.

In a galvanic cell, the oxidation and reduction of metals occurs at the electrodes. There are two electrodes in a very cell, one in each half-cell. The cathode is where reduction takes place and oxidation takes place at the anode.
I believe that the correct answer would be energy since you need energy for any kind of chemical change to occur. I hope this helped you with your question! If you have any questions please let me know and I might be able to further assist you.
I believe it's (C) Endothermic reaction
Explanation:
When energy is absorbed in an endothermic reaction, the temperature decreases.
