Answer:
The kind of ionic compound formed is MX2.
Explanation:
Element X electron configuration is represented as [core] ns2np5. The group in the periodic table this element belong to is group 7A. The element group is called the halogen family. Element X cannot be stated specifically, because the number is represented with n. Element X will behave as an anions when it react with a metal(cations). Element X has a charge of -1. The element X will gain electron when it bond with a metal. Element X is a non metal . Elements in this group are fluorine, chlorine, bromine, iodine , astatine, and tennessine . The element X have 7 valency electrons.
Element M electronic configuration is represented as [core]ns2. The group in the periodic table this element belong to is group 2A . The element group is called the alkaline earth metals family . Element M will behave as a cation when it bond with a non metal. Element M is a metal , therefore it will likely lose electron to form cations during bonding . The charge of element M is 2+. Element M is positively charged. Elements that belong to this group includes beryllium, magnesium, calcium, strontium, barium and radium. Element M has 2 valency electrons.
The reaction between this 2 ions will likely form an ionic compound . The element M is the cations while the element X is the anions. The element M will lose 2 electron while 2 atoms of element X will gain 2 electrons.Element M will lose 2 electron to attain a stable configuration while 2 atoms of element X will gain a single electron each to attain a stable configuration.
M²+ and F- . This will form MX2 when you cross multiply the charge. The kind of ionic compound formed is MX2.

Answer:
<h2>36.09 L</h2>
Explanation:
The initial volume can be found by using the formula for Boyle's law which is
![P_1V_1 = P_2V_2](https://tex.z-dn.net/?f=P_1V_1%20%3D%20P_2V_2)
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume.
Since we're finding the initial volume
![V_1 = \frac{P_2V_2}{P_1} \\](https://tex.z-dn.net/?f=V_1%20%3D%20%20%5Cfrac%7BP_2V_2%7D%7BP_1%7D%20%20%5C%5C)
We have
![V_1 = \frac{7.98 \times 14.2}{3.14} = \frac{113.316}{3.14} \\ = 36.0878...](https://tex.z-dn.net/?f=V_1%20%3D%20%20%5Cfrac%7B7.98%20%5Ctimes%2014.2%7D%7B3.14%7D%20%3D%20%20%20%5Cfrac%7B113.316%7D%7B3.14%7D%20%20%5C%5C%20%20%3D%2036.0878...)
We have the final answer as
<h3>36.09 L</h3>

Answer:
30 kJ
Explanation:
Arrhenius equation is given by:
![k=Aexp(-Ea/RT)\\](https://tex.z-dn.net/?f=k%3DAexp%28-Ea%2FRT%29%5C%5C)
Here, k is rate constant, A is Pre-exponential factor, Ea is activation energy and T is temperature.
taking natural log of both side
ln k = ln A - Ea/RT
In Arrhenius equation, A, R and T are constant.
Therefore,
![ln\frac{k_2}{k_1} =\frac{Ea_1-Ea_2}{RT}](https://tex.z-dn.net/?f=ln%5Cfrac%7Bk_2%7D%7Bk_1%7D%20%3D%5Cfrac%7BEa_1-Ea_2%7D%7BRT%7D)
is the lowering in activation energy by enzyme,
R = 8.314 J/mol.K
T = 37°C + 273.15 = 310 K
![\frac{k_2}{k_1} =1\times 10^5](https://tex.z-dn.net/?f=%5Cfrac%7Bk_2%7D%7Bk_1%7D%20%3D1%5Ctimes%2010%5E5)
![ln 1\times 10^5 =\frac{Ea_1-Ea_2}{RT}\\{Ea_1-Ea_2} = 11.512 \times 8.314 \times 310\\=29670\ J\\=30\ kJ](https://tex.z-dn.net/?f=ln%201%5Ctimes%2010%5E5%20%3D%5Cfrac%7BEa_1-Ea_2%7D%7BRT%7D%5C%5C%7BEa_1-Ea_2%7D%20%3D%2011.512%20%5Ctimes%208.314%20%5Ctimes%20310%5C%5C%3D29670%5C%20J%5C%5C%3D30%5C%20kJ)
KE=.5mv^2
M=mass
v=velocity
.5(4)(100)=200
That should be the answer.
