Question

What is the big idea of energy?????

It says : for level 6:

"Explained the reaction using the big idea of energy"

what does it mean by the big idea of energy????

Answer 1

http://www.pbs.org/wgbh/nova/einstein/legacy.html


That the sum total of energy and matter in the universe is constant, but that matter and energy are equivalent, and can be interchanged with each other.

Answer 2

The doesnt really help...

If it does, how do I use it to explain what happens when magnesium burns?

Answer 3

Was there stored energy in the chemical bonds of the Magnesium metal? Was it released when a reaction occured? Was the change in stored energy equal to the energy released?

Answer 4

Have you got the same stupid homework as me?
it says on my sheet that for lvl 7 i have to use symbols from a peridoic table to get a symbol equasion? does that mean stuff like C02 and stuff? And plz explaing what u mean by the total of energy something something with each other-i don't really get it much

Answer 5

and what happenes when you mix sulphur and iron together with a cotton ball jammed in the test tube??????
I know it turns black but why does there have to be cotton wool blocking it????!!!!
!?!?!?!?!?!?!?!?!?!?!!?!?!??!??!!?!?!???!!?
And do i needed to see what happens when i heat it up-or do i need o mix the together?
cos it has a piocture of a puddle with little black beans in it-
supposedly suphur and iron filings

Answer 6

to NHHS

yes it probably is the same sheet.
I've done it now so it doesn't matter...

yeah it does mean CO2 but it was
2Mg + O2 --> 2MgO

Answer 7

Im really confuzzled to! I have no idea what my teacher is going on about! What on earth does "the big idea of energy" mean? HELP!!!

Answer 8

I am really stuck on this piece i have done my particle model now on why sustances classified as an element and why there are same particles at the end and the begining Can anyone help me out

Answer 9

i need help with an answer which is level 6 do use a partical modle in detail how magnisium burns

Answer 10

errr ive got the sme friggin hw aswell
and the worst thing is is that we av to do it for our assesment
enyways the reason they put the cotton wool is to stop the smoke getting out
btw im in yr 8 so u no i migh be rong!!!

Answer 11

Well when magnesium burns it makes a realy big flsh which can realy hurt your eyes if you look at it

Answer 12

Same a bit stuck thing about mg and O2 ?? confused

Answer 13

I Have The Same Piece Of Homework I Reaaly Don't Understand, The Iron And Sulphur React To Form Iron Sulphide(Fe+S=FeS) And That You Have To Talk About This Reaction Using The Big Idea Of Energy ... Reaalllyy Conffuuseed Heelpp!!

Answer 14

I really don't get it mines on iron an sulphur and its like EXPLAIN THE REACTION USING THE BIG IDEA OF ENERGY. can any one help me please because I really don't under stand this ?!?!?!?

Answer 15

I know don't worry

Answer 16

arghhh! i don't get it when it says "explain the reaction using the big idea of energy!"

Answer 17

I have the same problem, apparently the big idea of energy is to do with heat and light energy being the same or summat. I have the 'Explaining what happens when we burn magnesium metal' HW it is sooooo annoying and I want to get a lvl 7 but I can't cos of the BIG IDEA OF ENERGY, I mean seriously?!?!

Answer 18

The big idea of energy transfer is the idea of a source of energy being changed into another form of energy such as light energy to heat energy. This effect happens in global warming where chemical energy is transfered into heat energy with a greenhouse effect

Answer 19

same homework = iron and sulphur and i really don't get what this big idea of energy is, apparently its something to do light and energy plllzzz hhhhhheeeelllllppp

Answer 20

HOW DO U DESCRIBE A REACTION USING THE BIG IDEA OF ENERGY????????????PLS HELP IMEDIATLY

Answer 21

im so suprised that we all have the same question. I'm stuck on the level 6 question where it says, big idea of energy. Although I think it's because the atom has more shells and more amount of electrons and protons so it has more stronger energy. And the outer shells have more likely to leave although there's only 3 shells so I'm not sure how that'd make sense😶

Answer 22

The big idea of energy is explaining it as though it is something else

Answer 23

Answer: the Energy between the atmos collided, resulting in a chemical bond of these two elements, creating a compound.

Answer 24

the iron and sulphur reaction homework is hard and annoying I

Answer 25

I have the same homework and i dont know you guys but i am pretty sure that the "big idea" of energy, is a phrase designed to point out that everything in the universe is energy in one form to another and that the sum of energy is maintained.
Energy can only be transferred or transformed from one form or another such as matter (substance) or light (radiation).
Matter is composed entirely of energy bound up in a specific form. Radiation is energy liberated to travel freely through space until it encounters and reacts or interacts with other energy and under the right conditions alters the properties of, adds to or becomes new matter.

Answer 26

wow 12 years and we still haven't figured it out; stuck on same question too btw at 4:00am

i think its to do with how the light and heat given off from magnesium and the air (oxygen) reacting shows a 1. chemical reaction (exothermic) and 2. how the big idea of energy actually occurs in the reaction


i dont know anymore its 4:28am and im tired this is all from the top of my head goodnight y'all

Answer 27

^^^ same as the last anonymous

=========================================================
Explain the reaction by using the Big Idea of Energy.
The reaction is helped by heat energy. There are two magnesium particles and two oxygen particles which then join together to create two magnesium oxide compounds.
