Answer:
3.5 Molar
Explanation:
Molarity = no of moles/ volume of solution in liter
Molarity = 1.75/0.50
Molarity = 3.5 molar
Answer:
When an atom of sodium and an atom of fluorine combine to form the salt, sodium fluoride, an ionic bond, is formed.
Explanation:
Explanation:
This is expressing as a subject of a formula of a specie.
This equation is used in solving for specific heat capacity of a material;
equation:
c = 
First cross multiply:
c[M(T2 - T1)] = h
Then multiply both sides by
:
x c[M(T2 - T1)] =
x h
M(T2 - T1) = 
Multiply both sides by 
x M(T2 - T1) = 
T2 - T1 = 
Now rearrange to produce;
T1 = T2 +

Answer:
Explanation:
Potential energy is the energy possessed by an object due to its position. For example, when the ball starts to move from its resting position then the ball gains kinetic energy. Thus, as gravity makes an object fall down toward the ground, potential energy becomes kinetic energy.
Answer:
Wave is a disturbance or energy that propagate through medium from one point to other point
So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.
This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion
This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order
For an example
y(x,t) = Asin(kx - ωt + φ)
So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"
Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value
Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.
