Full Question:
What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom?
Explanation:
This covalent compound is the hydrogen cyanide, HCN.
The following steps are used to obtain it;
Step 1. Draw a skeleton structure of the compound based on the elements
Put the least electronegative atom C in the middle with H and Cl on either side.
H-C-N
Step 2. Count the valence (outermost) electrons you can use
H + C + N = 1 + 4 + 5 = 10
Step 3. Add these electrons to give every atom an octet
You have to put a triple bond between C and N.
Note: Each bond is made up of two electrons.
The lewis structure is given in the image below;
Answer:
Average speed meter per second
Explanation:
Given
The total distance walked meters
The total time taken to walk meters is
minutes
In one minute there are seconds
As we know Average speed is equal to total distance travelled divided by total time taken
Hence,
Average speed
meter per second
Answer:
+0.231 m/s
Explanation:
The problem can be solved by using the law of conservation of momentum. In fact, we have that the total momentum before the collision must be equal to the total momentum after the collision:
where we have
m1 = 245000 kg is the mass of the first car
m2 = 57500 kg is the mass of the second car
u1 = 0.513 m/s is the initial velocity of the first car
u2 = -0.125 m/s is the initial velocity of the second car
v = ? is the final velocity of the two cars together, after the collision
Solving the equation for v, we find
And the direction (positive sign) is the same as the initial direction of the first car.
