Newton's third law of motion is summarized as the law of action-reaction. For every action, there is an equal but opposite reaction. Which example best illustrates the application of Newton's law of action-reaction? Choose all that apply.
Answer:
When we stand on the floor, we apply a force on the floor surface in the downward direction and in return the floor also exerts an upward and equal force on us.
Explanation:
Newton' third law is vey famous and it states that for each and every action, there applies an equal but opposite reaction. Thus the action force and the reaction force always acts on pairs. But they does not contribute to the motion of the object.
One such example that illustrates the action and reaction force from Newton's law is when we stand on the floor we exert a force on the floor surface in downward direction. The floor surface also exerts an opposite and equal force on us in the upward direction.

Calcular una solución que contiene 250 g de cloruro de calcio en 1500 mL de solución y tiene una decidad de 1,2gr/ml
Answer:
13.89% p/p
Explanation:
El porcentaje peso a peso de una solución (%p/p) es definido como cien veces la relación entre la masa del soluto (En este caso, cloruro de calcio) y la masa de la solución. La ecuación es:
%p/p = Masa cloruro de calcio (250g)/ Masa solución * 100
Para hallar la masa de la solución debemos usar el volumen y la densidad de este:
1500mL * (1,2g / mL) = 1800g
Así, el %p/p será:
250g / 1800g * 100
13.89% p/phow to obtain pure aluminium oxide from sodium aluminate. pls help.
Answer:
By Bayer process.
Explanation:
In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process.
The pressure of a gas is 440. mm Hg. Express this in units of (a) atmospheres, (b) bars, and (c) pascals.
Answer: a) 0.579 atm
b) 0.585 bar
c) 58662 Pa
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..
All these units of pressure are inter convertible.
We are given:
Pressure of the gas = 440 mmHg
a) Converting this unit of pressure into 'atm' by using conversion factor:
[tex]760mmHg=1atm[/tex]
[tex]440mmHg=\frac{1}{760}\times 440=0.579atm[/tex]
b) Converting this unit of pressure into 'bars' by using conversion factor:
[tex]760mmHg=1.01bar[/tex]
[tex]440mmHg=\frac{1.01}{760}\times 440=0.585bar[/tex]
c) Converting this unit of pressure into 'Pascal' by using conversion factor:
[tex]760mmHg=101325Pa[/tex]
[tex]440mmHg=\frac{101325}{760}\times 440=58662Pa[/tex]
Calculate the number of moles in 7.04 g of lead (II) nitrate, Pb(NO3)2
Can Someone help me covert this?!
Answer:
moles Pb(NO₃)₂ ≅ 0.0213 mole (three sig. figs.)
Explanation:
converting...
grams to moles => divide by formula weight
moles to grams => multiply by formula weight
for this problem ...
moles Pb(NO₃)₂ = 7.04g / 331.2g/mol = 0.021256 (calculator answer)
≅ 0.0213 mole (three sig. figs.)
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the number of moles in 7.04 g of lead (II) nitrate, Pb(NO₃)₂ is 0.0212moles.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
mole =given mass ÷ molar mass
Molar mass of 1 mole of Pb(NO₃)₂ = 331.2g/mol
given mass of Pb(NO₃)₂=7.04g
Substituting the values in above formula we get
moles of Pb(NO₃)₂ = 7.04g / 331.2g/mol
moles of Pb(NO₃)₂ = 0.0212moles
Therefore, the number of moles in 7.04 g of lead (II) nitrate, Pb(NO₃)₂ is 0.0212moles.

Image B will shows the butter particles before and after thermal energy will be transferred to the solid butter by heating. So, the correct option is B.
What is Thermal energy?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process.
The butter particles in Picture B are shown both before and after the solid butter has been heated to transmit thermal energy to it. This image shows a solid butter particle with tightly packed molecules, however when the butter is heated, it melts into a liquid form with loosely packed molecules.
Thus, the correct option is B.

What is the percentage by mass of sulphur in Al2(SO4)3[A12SO4 =
342g/mol, S = 32]
Answer: The percentage by mass of sulphur in [tex]Al_2(SO_4)_3[/tex] is 9.36%
Explanation:
Mass percent of an element is the ratio of mass of that element by the total mass expressed in terms of percentage.
[tex]{\text {Mass percentage}}=\frac{\text {mass of sulphur}}{\text {Total mass}}\times 100\%[/tex]
Given: mass of sulphur = 32 g/mol
mass of [tex]Al_2(SO_4)_3[/tex] = 342 g/mol
Putting in the values we get:
[tex]{\text {Mass percentage}}=\frac{32g/mol}{342g/mol}\times 100\%=9.36\%[/tex]
The percentage by mass of sulphur in [tex]Al_2(SO_4)_3[/tex] is 9.36%
