A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.
In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula 
where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula 
to chlorine which gains electron and thus results in an anion formation having formula 
. The force of attraction between these oppositely charged ions that helds them together and results in formation of compound is electrostatic force of attraction.
Hence in salt, the nature of bond between sodium and chlorine is ionic.
Answer:
14.99 mols of CO2
Explanation:
STP= 273 k , 1 atm , .0821 gas constant
N=PV/RT
N= 1x336/.0821x273
14.99 mols of CO2
659.6 grams of CO2
Unrestricted populations of organisms experience Exponential growth.
As a population reaches is carrying capacity there is an increase in competition for All of the above.
Hope I helped.
This is a simple chemical change due to what it produces and how it is added together. Hope this helps.
Here's the solution,
we know,
<u>potential energy</u> = mgh
where,
- m = mass = 0.5 kg
- g = acc due to gravity = 9.8 m/s²
- h = height = 0.8 m (80 cm)
So,
