Answer:
Most similar - Lithium
Least similar - Phosphorus
Explanation:
Rubidium is an element in group 1A of the periodic table. It is a metal and forms an ionic compound with chlorine. The formula of the compound is RbCl.
If we look at the options, Lithium is also a group 1A element and forms an ionic compound with chlorine having the formula LiCl which is very much similar to RbCl chemically.
Phosphorus is a nonmetal. Its compounds with chlorine, PCl3 and PCl5 are covalent and does not resemble RbCl in any way.
Answer:
Element X has valency 2 while Y Valency 2, element Y has high tendency of gaining electrons for its stability thus the compound formed will be B
elements X is positively charged while Y will be negatively charged
Answer:
![P_2=1.1x10^6Pa](https://tex.z-dn.net/?f=P_2%3D1.1x10%5E6Pa)
Explanation:
Hello.
In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:
![P_2=\frac{P_1V_1}{V_2}](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7BP_1V_1%7D%7BV_2%7D)
Consider that the given initial pressure is also equal to Pa:
![P_2=\frac{1.00x10^5Pa*11.00m^3}{1.00m^3}\\ \\P_2=1.1x10^6Pa](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7B1.00x10%5E5Pa%2A11.00m%5E3%7D%7B1.00m%5E3%7D%5C%5C%20%5C%5CP_2%3D1.1x10%5E6Pa)
Which stands for a pressure increase when volume decreases.
