The charge of an e- is 1.60217657×10^-19 coulombs I.e. A very small number!
So 1 coulomb is much much bigger than the charge of an electron.
Answer:
It is a chemical change
Explanation:
The combination of sodium hydroxide and fat yields soap and glycerine.
We have to remember that one of the characteristics of a chemical change is that new substance(es) is/are formed. We have to look out for this when considering any process.
We can see here that new substances were formed (soap and glycerine). Based on this, we can assert that a chemical change has taken place.
Answer:
Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).
Answer:
C4H8O4
Explanation:
Let (CH20)x
C=1*12.01=12.01 (12.01, 1.01, 16.00 Avg mass of elements)
H=2*1.01=2.01
O=1*16.00=16.00
12.01 + 2.01 + 16.00 = 30.03
120.12/30,03=4
==> (CH2O)4 = C4H8O4
Carbon, hydrogen should be the answer
