Prove that:-
1.The unit of pressure is a derived unit?
2.The unit of work is a derived?​

Answers

Answer:01

When you describe nature, and you need standard, useful units for everything you will see that these units are linked. So you start with defining base units that are simple:

kg, meter, second, Kelvin, …

Now other units will be automatically derived:

speed = distancetime , so the unit is  ms  

acceleration =  speedincreasetime , so the unit is  ms2  

Force = Mass x acceleration, so the unit is  kg.ms2  

Pressure is Force/surface, so the unit is  kgm.s2  

You can define new simple units for this, but they are still derived from the base units:

Force:  1N=1kg.ms2  

Pressure:  1Pa=1kgm.s2

2 Answer

In mechanics, work is defined as “force x distance”. Since energy can be measured as work, we can write energy = force x distance. Thus SI derived unit of energy has the units of newtons x meter or kg m2/s

How are conduction, convection, and radiation different? Conduction transfers thermal energy by . Convection transfers thermal energy by . Radiation transfers thermal energy by .

Answers

Answer:

See explanation

Explanation:

There are three modes of heat transfer; conduction, convection and radiation.

Conduction refers to the transfer of heat without the actual movement of the particles of matter.

Convection is the transfer of heat by the actual movement of the particles of matter.

Radiation is the transfer of heat without a material medium.

Hence the three modes of heat transfer differ in the actual mechanism by which heat energy is transferred as shown above.

The partial pressure of carbon dioxide in air varies with the seasons. Would you expect the partial pressure in the Northern Hemisphere to be higher in the summer or winter

Answers

Answer:

It will be higher in the summer.

Explanation:

Usually, the winter season is more harsh a weather on leaves than summer because it is wet season and thus has less sunlight and this means there will be less photosynthesis reactions and therefore it means the partial pressure will be lesser here unlike in the summer when it is a more warm and dry weather with sunlight where photosynthesis reactions will be more favorable to occur.

Thus, CO2 which is a great component of photosynthesis is used more in the summer and as such the partial pressure in the summer will be higher.

Answers

Answer:

1. How do metals and non-metals react with acids?

Ans : Non metals does not react with acids while metals react with acids and produce hydrogen gas that burns with a 'pop'sound.

2. Write and explain the chemical equation for the reaction of magnesium with sulphuric acid and aluminium with hydrochloric acid.

Magnesium + sulphuric acid = Hydrogen + salt

Mg(s) + H2SO4 (aq) MgSO 4(aq) +H2 (g)

Aluminium + Hydrochloric acid = Hydrogen + Aluminium chloride

2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)

Answer:

Metals react with acid but non metals donot react with acid because

when a substance, reacts with acids it provides electrons to the H+ ions produced by the acids. Non-metals are acceptors of electrons and hence, they cannot donate electrons.

Fe-54 = 5.845%

Calculate the average atomic mass/ given their percent abundance

Answers

Answer:

55.768

Explanation:

The following information is given in this question:

Fe-54 = 5.845%

Fe-56 = 91.754%

Fe-58 = 2.119%

First, we convert from percentage abundance to decimal abundance

Fe-54 = 5.845% = 0.05845

Fe-56 = 91.754% = 0.91754

Fe-58 = 2.119% = 0.02119

To find the average atomic mass of iron (Fe), we multiply each isotopes' decimal abundance by its mass no and find the sum as follows:

Average atomic mass = (0.05845 × 54) + (0.91754 × 56) + (0.02119 × 58)

Average atomic mass = 3.1563 + 51.38224 + 1.22902

Average atomic mass = 55.768

Answers

The question is incomplete, the complete question is;

As Danny was pouring cereal for his breakfast, he noticed that the cereal box says that the cereal contains 5 milligrams of iron per serving. Danny decided to perform an experiment to test this claim. He found that the cereal contains 4.6 milligrams of iron per serving. Based on Danny's measurement, the value reported on the label is ( CORRECT OR INCCORECT) because A: (IT IS DIFFERENT FROM THE VALUE DANNY MEASURED) B: (IT IS REORTED TO THE NEAREST MILLIGRAM) C: (IT USES THE SAME UNITS THAT DANNY USED).

Answer:

CORRECT because IT IS REORTED TO THE NEAREST MILLIGRAM

Explanation:

In mathematics, values may be rounded up or down as required. In the case of this measurement of cereals by Danny, it is customary to measure the amount of iron per serving to the nearest milligram.

As such, even though Danny found out that the actual amount of iron per serving in the cereal is 4.6 milligrams, the value reported on the cereal box is still correct because it was reported to the nearest milligram hence the value had to be rounded up.

For a reaction, AH = 176 kJ/mol and A SO = 0.285 kJ/(K•mol). At what
temperatures is this reaction spontaneous?
A. At no temperature
B. T< 50 K
C. T>617 K
D. T< 617 K

Answers

Answer:

C. T>617 K

Explanation:

We are given that

[tex]\Delta H=176KJ/mol[/tex]

[tex]\Delta S=0.285KJ/K\cdot mol[/tex]

We have to find the temperature at which the reaction is spontaneous.

When

[tex]\Delta H>0, \Delta S>0[/tex]

Therefore, the reaction is spontaneous at certain range of temperature.

Option A is not true.

[tex]\Delta G=\Delta H-T\Delta S[/tex]

When [tex]\Delta G[/tex] is negative, then  the reaction is spontaneous.

[tex]\Delta G=176-0.285T[/tex]

When T<50

Suppose T=49 K

[tex]\Delta G=176-49\times 0.285>0[/tex]

Therefore, [tex]\Delta G is positive[/tex].Hence, the  reaction is not spontaneous.

Option B is wrong.

C.T>617K

Suppose T=618 K

[tex]\Delta G=176-0.285\times 618=-0.13<0[/tex]

Therefore, [tex]\Delta G is negative[/tex].Hence, the  reaction is spontaneous.

So, option C is true.

D.T<617 K

Suppose T=616 K

[tex]\Delta G=176-0.285\times 616=0.44>0[/tex]

Therefore, [tex]\Delta G is positive[/tex].Hence, the  reaction is not spontaneous.

So, option D is not true.

Na3N decomposes to form sodium and nitrogen gas at STP. If 13.7 L of nitrogen is produced
how many moles of Na3N was used? (22.4 L = 1 mole of any gas)
2Na3N --> 6Na + N2

Answers

Answer: 1.224 moles of [tex]Na_3N[/tex] were used.

Explanation:

We are given:

Volume of nitrogen gas produced = 13.7 L

At STP conditions:

22.4 L of volume is occupied by 1 mole of a gas

Applying unitary method:

13.7 L of nitrogen gas will be occupied by = [tex]\frac{1mol}{22.4L}\times 13.7L=0.612mol[/tex]

For the given chemical reaction:

[tex]2Na_3N\rightarrow 6Na+N_2[/tex]

By Stoichiometry of the reaction:

1 mole of nitrogen gas is produced by 2 mole of [tex]Na_3N[/tex]

So, 0.612 moles of nitrogen gas will be produced from = [tex]\frac{2}{1}\times 0.612=1.224mol[/tex] of [tex]Na_3N[/tex]

Hence, 1.224 moles of [tex]Na_3N[/tex] were used.

Given 1.25 x 10²⁴ molecules of Cl₂ = 1.25 x 10²⁴molecules Cl₂(g)/6.023 x 10²³ molecules/mole = 2.08 mole Cl₂(g)

2Na(s)    +      Cl₂(g)      =>   2NaCl(s)

excess        2.08mole          ? mole

∴moles NaCl(s) formed from 2.08 moles Cl₂(g) = 2(2.08 mole NaCl(s))
