The answer is
<h2>720 Joules</h2>Explanation:
The kinetic energy of a body can be found by using the formula
<h3>where
m is the mass
v is the velocity / speed
From the question
mass = 10 kg
velocity = 12 m/s
Substitute the values into the above formula and solve
That's
<h3>We have the final answer as
<h3>720 Joules</h3>Hope this helps you
Answer:
The Lewis structures are in image attached.
Explanation:
Lewis symbol is a representation of an element symbol along with its valence electrons around it in the form of dot(s).
Mono-atomic ions formed from the following :
(a) Cl
Chlorine's atomic number is 17 in which only 7 electrons are present in its valence shell .So in order to gain noble gas stability it will gain 1 electron to completes its octet
(b) Na
Sodium's atomic number is 11 in which only 1 electrons are present in its valence shell .So in order to gain noble gas stability it will loose 1 electron to completes its octet. In the Lewis symbol no dot shown as sodium has lost its 1 electron.
(c) Mg
Magnesium's atomic number is 12 in which only 2 electrons are present in its valence shell .So, in order to gain noble gas stability it will loose 2 electrons to completes its octet.
In the Lewis symbol no dot shown as magnesium has lost its 2 electrons.
(d)Ca
Calcium's atomic number is 20 in which only 2 electrons are present in its valence shell .So, in order to gain noble gas stability it will loose 2 electron to completes its octet.
In the Lewis symbol no dot shown as calcium has lost its 2 electron.
(e) K
Potassium's atomic number is 19 in which only 1 electrons are present in its valence shell .So, in order to gain noble gas stability it will loose 1 electron to completes its octet.
In the Lewis symbol no dot shown as calcium has lost its 1 electron.
(f) Br
Bromine's atomic number is 35 in which only 7 electrons are present in its valence shell .So in order to gain noble gas stability it will gain 1 electron to completes its octet
(g) Sr
Strontium's atomic number is 38 in which only 2 electrons are present in its valence shell .So, in order to gain noble gas stability it will loose 2 electron to completes its octet.
In the Lewis symbol no dot shown as calcium has lost its 2 electron.
(h) F
Florine's atomic number is 7 in which only 7 electrons are present in its valence shell .So in order to gain noble gas stability it will gain 1 electron to completes its octet.
