How do S and P waves move through a solid material?
abruzzese [7]

P waves move quickly and S waves move slowly through solids,

Explanation:

S and P waves can move through a solid material. P waves generally moves quickly and S-waves move slowly through solids.

S and P waves elastic seismic waves.

  • P waves are primary waves travels through any material medium. They move faster than S-waves.
  • S waves are secondary waves that moves through solid only. They are shear waves.
  • They cannot move through liquids and gases because these materials cannot be sheared.

At a seismic station, P waves arrives first because they have a higher velocity

The enthalpy of vaporization of water at 373 K and 1 bar is 40.7 kJ/mol and the molar heat capacities are 75.3 J/(mol K) for liq
Soloha48 [4]

Answer:

The enthalpy of vaporization of water at 273 K and 1 bar = 44.9 KJ/mol

Explanation:

Enthalpy of vaporization of water at 273 K, ΔHvap(T₂) is given as;

ΔHvap(T₂) = ΔHvap(T₁) + ΔCp * (T₂ - T₁)

where ΔCp = molar heat capacity of gas - molar heat capacity of liquid

Therefore, ΔCp = (33.6 - 75.3) = -41.70 J/(mol K) = 0.0417 kJ/(molK)  

substituting  ΔCp = 0.0417 kJ/(mol K)  in the initial formula

;

ΔHvap(T) = ΔHvap(T1) + ΔCp * (T₂ - T₁)

ΔHvap(T₂)= 40.7 kJ/mol + {-0.0417 kJ/(mol K) * (272 - 373 K)}

ΔHvap(T₂) = 44.9 kJ/mol

Therefore,  enthalpy of vaporization of water at 273 K and 1 bar = 44.9kJ/mol

Can you help me on this since im struggling on this since day 1
emmasim [6.3K]
Of Ok here is what I am thinking.

Simple replacement means when one element or compound moves out of another element and is replaced by this compound.

For example if you have A+BC ----- AC + B

Most of the time the one which is replaced is found on the right and the left one is going be only one element or compound.

Double replacement means when the two compounds exchange the positive and negative ions. Ok let see this example:


AB+ CD------- AD+ BC
this means if A have  + sign and D has - sign they will share to form new compound the same is true for DC. Don't forget that all compounds are formed from positive and negative ions. 

                                 QUESTIONS
CUSO4 + NA2S---- CUS + Naso4[ double replacement]
KBR +Pb[CLO3]2------K[clo3]2 +PbBr [ double replacement]
I do not  think these questions can be single replacement.
I hope this may helps you.

What is the charge of 5protons 6 neutrons and 5 electrons
Darya [45]

Answer:  

In this case the mass number would be 11.

Explanation:

The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).

PLEASE HELP!! 20 POINTS!
Vinvika [58]

Answer:

Energy transformation, also known as energy conversion, is the process of changing energy from one type of energy to another. In physics, energy is a quantity that provides the capacity to perform work (e.g. lifting an object) or provides heat. In addition to being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed.

The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home's air to raise its temperature.
