At home, your parents replace your house lights with lower-watt bulbs. Is this energy conservation or energy sustainability? Explain
This is actually electricity
The replacing of house lights with lower-watt bulbs represents energy conservation not energy sustainability because energy conservation is the efficient use of energy without wasting it.
What is energy conservation?Energy conservations refer to the practice of using less energy for doing various activities. Turning off the light when you leave the room is the example of energy conservation.
So we can conclude that replacing of house lights with lower-watt bulbs represents energy conservation not energy sustainability because energy conservation is the efficient use of energy without wasting it.

V. What volume of nitric oxide will diffuse out of a porous partition in 10 seconds when 25 ml of methane diffuse out in 4 seconds?
The volume of nitric oxide that will diffuse out of the partition in 10 seconds when methane diffuses is 62.5 mL
What is rate of diffusion?This is defined as the amount diffused per unit time. Mathematically, it can be expressed as
Rate = volume / time
How to determine the rate of diffusion of methaneVolume of methane = 25 mLTime = 4 sRate = ?Rate = volume / time
Rate = 25 / 4
Rate = 6.25 mL/s
How to determine volume of nitric oxideTime = 10 sRate = 6.25 mL/sVolume of nitric oxide = ?Rate = volume / time
6.25 = volume of nitric oxide / 10

What is the mass of NaCl required to make 160 grams of a 12% solution of NaCl in water?
18 grams
19 grams
22 grams
24 grams
Answer: 19 grams
Explanation:
percent by mass = (mass of part)/(mass of whole) * 100
this means that in this question, 12 = x/160 * 100, where x is the amount of NaCl.
this means 12/100 = x/160, and thus x = (160)(12/100)=19.2 grams
The closest option is B.
Answer:
Second Option: 19 grams
Explanation:
Total solution weight: 160 grams
percent of NaCl in the solution: 12%
You take these two numbers and multiply them with 12 being over 100:
160 * [tex]\frac{12}{100}[/tex] = 19.2 grams
and then just round to the nearest whole number: 19 grams

Write down the names of subatomic particles and their masses in a.m.u with their unit charges.
Subatomic particle is the smallest particle than the atom
Explanation :-
An atom consist of three subatomic particle
They are electron , proton and neutron .
Proton ( p ) it is a subatomic particle with positive chargewhich is equal to electron charge and a mass of
[tex]1.67262 \times {10}^{ - 27} kg [/tex]
Electron ( e ) It is the subatomic particle with negative charge and a mass equal to
[tex]9.109 × {10}^{ - 31}kg [/tex]
Neutrons ( n ) - It is neutral subatomic particle which is the constituent of every atomic nucleus except hydrogen . Neutrons have no electric charge and a rest mass equal to
[tex]1.67493 \times {10}^{ - 27} kg[/tex]
slightly greater than that of electron
Explanation:
INTRODUCTION:
There are 3 main subatomic particles, they are:
ElectronsProtons NeutronsThe existence of the sub-atomic particles was proved by the fact that an atom is electrically neutral but it can be made to gain a positive or a negative charge. This means that an atom must contain tiny particles, each carrying either a positive or a negative charge.
These opposing charges balance each other under ordinary conditions to make an atom electrically neutral.
ELECTRONS:
Electrons were discovered in 1897 by J.J. THOMSON when he was studying cathode rays.An electron is denoted by:
[tex] \boxed{ _ {- 1 }e {}^{0} }[/tex]
Where,
0 = represents it's mass-1 = represents it's unit negative electrically charge.Properties of electrons:
An electron is a negatively charged particleThey are an integral part of all atomsThe properties of electrons are Independent of the nature of the gas in the discharge tubeAn electron has a mass of 9-108 x 10 g which is only 1/1837 of the mass of a hydrogen atom. Therefore, an electron is said to have negligible massAn electron carries one unit negative (-1) charge, which is equal to 1-602 x 10 coulombs.UNIT CHARGE OF Electrons:
9.1 × 10^(-28) gramsNEUTRONS:
In 1932, James chadwick discovered neutrons & it had no charge. Its denoted as [tex] _{0} n ^1[/tex]
PROPERTIES OF NEUTRONS:
Electrically a neutron is neutral, i.e it has no chargeNeutrons are present in the nucleus of an atomAtoms of the same element may differ in the number of neutrons leading to formation of isotopes.An atom of hydrogen contains only 1 proton and one electron but no neutron.
UNIT CHARGE OF IT:
1.676 × 10^(-24) gramsPROTONS:
An atom is electrically neutral Therefor the presence of the negatively charger electrons in an atom suggests that it must contain positively charged particles a well, otherwise an atom would not b electrically neutral.It is discovered by E. GOLDSTEIN.
It's denoted as [tex] _{+1} p ^1[/tex]
where 1 represents 1 a.m.u. and +1 represents 1 unit positive charge.
PROPERTIES:
A proton is a positively charged particle.The mass of a proton is 1.672 × 10^(-19). ie equal to the mass of an atom of hydrogenA proton carries 1 unit positive (+1) charge , and equals to 1.602 × 10^(-19) coulombs.>>>All elements contains electrons & protons.
Since an atom is electrically neutral, the number of electrons in an atom is equal to the mumber of protons in that atom. However, no two elements contain the same number of protons in their respective nuclei.
UNIT Charge:
1.6 × 10^(-24) grams.[All units I provided are a.m.u. .]
