why is fluorine more chemically reactive than
nitrogen?
Answer:
Nitrogen has Electronic configuration 1s2 2s2 2p3. Fluorine has Electronic configuration 1s2 2s2 2p5 i.e. nitrogen has half filled p subshell that makes it more stable than fluorine and fluorine requires only 1 electron to complete it's octet to get stable..Therefore Fluorine is more reactive than Nitrogen.
Hope it helps you

A ball with a volume of 1.0 L is filled with a gas at 5 atmospheres (atm). If the volume is reduced to 0.75 L without a change in temperature, what would be the pressure of the balloon?
Answer:
P2 = 6.67 atm
Explanation:
Given the following data;
Initial volume = 1 Liters
Initial pressure = 5 atm
Final volume = 0.75 Liters
To find the final pressure P2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 5 * 1 = P_{2} * 0.75 [/tex]
[tex] 5 = 0.75_{2} [/tex]
[tex] P_{2} = \frac {5}{0.75}[/tex]
[tex] P_{2} = 6.67[/tex]
P2 = 6.67 atm
Therefore, the new pressure is 6.67 atm.

Answer:
slowing down.
Explanation:

Koby placed ½ teaspoon of baking soda into each of two identical glasses. He noticed the baking soda was lumpy, so he used a fork to break up the lumps. Why is it important to break up the lumps?
Answer:
because the lumps are just baking soda covered with whatever watery substance you used.
Explanation:
so pretty much inside the lumps is just a bunch of baking soda
Kamal, Kamala, Krishna invert a sum of RS= 30,000 on a business in the ratio 2 : 3 : 5. Find the each of their investment.
Answer:
Explanation:
Kamal, Kamala, Krishna invert in the ratio 2 : 3 : 5.
As 2+3+5 =10, their respective share is 2/10, 3/10 and 5/10.
Sum of investment = 30000Rs
Kamal's investment = 30000 * 2/10 = 6,000 Rs
Kamala's investment = 30000 * 3/10 = 9,000 Rs
Krishna's investment = 30000 * 5/10 = 15,000 Rs

Explanation:
A golfer wants his shot to land
122 m away on flat ground.
His club launches balls at a 55.0°
angle. How fast should
the ball leave the club?
(Unit = m/s)
Answer:
35.67 m/s
Explanation:
Applying the formular for range,
R = u²sin2∅/g....................... Equation 1
Where R = Range, u = Initial Velocity, ∅ = angle of launch, g = acceleration due to gravity
make u the subject of the equation
u = √(Rg/sin2∅)............. Equation 2
Given: R = 122 m, g = 9.8 m/s², ∅ = 55°
Substitute these values into equation 2
u = √[(122×9.8)/(sin(2×55))]
u = √(1195.6/sin110)
u = √(1272.33)
u = 35.67 m/s
Answer:
35.67

Explanation:
An elevator is rising up a vertical shaft in a skyscraper. Between the 12th and 20th floors, it travels at a constant speed. During this time period:
1.) The only unbalanced force acting on it is air resistance.
2.) The forces acting on it are balanced so the net force is zero.
3.) The upward force is greater than the combined downward forces of gravity and air resistance, making it move upward.
4.) There are no forces acting on it so the net force is zero.

A student of mass 45kg, who is undergoing National Service training, takes 6s to climb a flight of stairs that had 36 steps. If each step is 16cm high, what is the power of the student?
Answer:
Approximately [tex]4.2 \times 10^{2}\; \rm W[/tex] on average in the vertical direction (assuming that [tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex].)
Explanation:
Vertical displacement of this student in [tex]6\; \rm s[/tex]: [tex]36 \times 16\; \rm cm = 36 \times (0.16\; \rm m) = 5.76\; \rm m[/tex].
Average vertical velocity of this student: [tex]v = \displaystyle \frac{5.76\; \rm m}{6\; \rm s} = 0.96\; \rm m \cdot s^{-1}[/tex].
The average vertical force that this student exerts on the ground would be equal to the weight of this student:
[tex]F = W = m \cdot g = 45\; \rm kg \times 9.8\; \rm N \cdot kg^{-1} = 441\; \rm N[/tex].
The average power of this student in the vertical direction is equal to the product of the force and velocity of this student in that direction:
[tex]P = F \cdot v = 441\; \rm N \times 0.96\; \rm m \cdot s^{-1} \approx 4.2\times 10^{2}\; \rm W[/tex].

A 7 kg ball is push with a force of 28 N. What is the acceleration? .
Answer:
a = 4 m/s²
Explanation:
Given: 28 N, 7 kg
To find: Acceleration (a)
Solution: To find (a), divide force by weight
A = F ÷ m
= 28 ÷ 7
= 4 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
