Ionic bonding is defined as the total transfer of valence electrons between atoms. What happens in ionic bonding is that a metal loses electrons to become a positive charged cation. On the other hand, the nonmetal receives those electrons to become a negatively charged anion. From the given choices above, the option that you would expect to form an ionic bond when combined is option A. Ca and O.
Answer:
There are a number of ways that you could investigate the effect of changing the temperature on the rate of a reaction in Chemistry. ... This includes using apparatus safely, and monitoring chemical changes.
Explanation:
There are three main methods of measuring rate:
measuring the volume of gas given off by a reaction over time.
measuring the loss of mass of a reaction over time when a gas is produced.
Answer:
It's compound? It's chemical compound would be represented my letters or numbers
Answer:
B. Poor conductor.
Explanation:
It cannot be A, as only 1 metal is not solid at room temp.
It cannot be C, as most metals are ductile.
It cannot be D, as most metals are malleable.
This leaves B, which is not true about metals, as a lot are very good conductors.
Answer :
(a) The speed in Km/hr is,
(b) The speed in mi/min is,
Solution :
The speed of light =
(a) Convert speed of light from m/s to Km/hr
conversions used :
(1 Km = 1000 m)
(1 hr = 3600 sec)
(b) Convert speed of light from m/s to mi/min
conversions used :
