I think the answer is true
The answer is; D
While electromagnetic waves travel at an astounding 3.00 x 10^8 m/s and any delay seems imperceptible in short distances, in long distances, the waves take some time to reach the other end. This is why there is usually a small delay when ground communication tries to reach astronauts in space. Also, remember that when a communication is relayed from the earth, it has to reach the destination and then wait for a response back to earth which covers the same distance or longer/shorter if the target is moving.
The distance to the moon is 384,400 km, therefore multiply this by 2 = 768,800 km
768,800,000m/300,000,000m = 2. 56 seconds
Therefore radio waves sent to the moon from earth will have a minimum 2.5 seconds delay not considering the processing time of this communication by the destination before sending feedback. ‘Over to you’ signals end of a message by the messenger hence allowing the other messenger on the other to respond.
Answer: The bond formed between magnesium and oxygen is an ionic bond.
Explanation:
An ionic bond is formed when an atom transfer its valence electrons to another atom.
Whereas, a covalent bond is formed by the sharing of electrons between the atoms.
Silicon and oxygen forms silicon dioxide. Silicon has 4 valence electrons which are shared with each oxygen atom. Hence, silicon and oxygen forms a covalent bond.
Oxygen and oxygen shares two pairs of electrons therefore, a covalent bond is formed between oxygen and oxygen.
A covalent bond is formed between carbon and hydrogen as carbon has 4 valence electrons which are shared with four hydrogen atoms.
Magnesium has 2 valence electrons which are transferred to the oxygen atom in order to complete its octet.
Therefore, the bond formed between magnesium and oxygen is an ionic bond.
