Answer:
C. Cs < K < P
Explanation:
Electronegativity is the basically the tendency of an atom to attract electrons. The pauling scale is used to quantify electronegativity, the most electronegative element; fluorine has a value of 4.0 and francium, the least electronegative element has a value of 0.7
The electronegative values of the following elements are given as;
K = 0.82
Cs =0.79
P = 2.19
Arranging in order of increasing electronegativity, we have;
Cs < K < P. The correct option is;
C. Cs < K < P
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.
![AB\rightarrow A+B](https://tex.z-dn.net/?f=AB%5Crightarrow%20A%2BB)
Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.
![AB+CD\rightarrow AD+CB](https://tex.z-dn.net/?f=AB%2BCD%5Crightarrow%20AD%2BCB)
Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.
![A+B\rightarrow AB](https://tex.z-dn.net/?f=A%2BB%5Crightarrow%20AB)
Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.
![A+BC\rightarrow AC+B](https://tex.z-dn.net/?f=A%2BBC%5Crightarrow%20AC%2BB)
In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has
as a component.
The reaction between HCl and
is a type of neutralization reaction and it is a type of double displacement reaction.
The equation between the two follows:
![CaCO_3+HCl\rightarrow CaCl_2+H_2O+CO_2](https://tex.z-dn.net/?f=CaCO_3%2BHCl%5Crightarrow%20CaCl_2%2BH_2O%2BCO_2)
Hence, the correct answer is Option B.
Significant figures communicates the level of precision in measurements.
