<u>Answer:</u> In a chemical reaction, the total mass of the particles in the system stays the same
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.
Every balanced chemical reaction follows law of conservation of mass.
<u>For Example:</u> Formation of water molecule
Total mass on reactant side = ![[2(2\times 1)+(2\times 16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%282%5Ctimes%201%29%2B%282%5Ctimes%2016%29%5D%3D36g%2Fmol)
Total mass on product side = ![[2((2\times 1)+16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%28%282%5Ctimes%201%29%2B16%29%5D%3D36g%2Fmol)
Hence, in a chemical reaction, the total mass of the particles in the system stays the same
Answer:
6 orbitals
Explanation:
you take the total number of orbitals there would normally be and add that to three and you get a total of 6 orbitals in axial.
Answer:
Spiders and ground beetles.
Why is Anthony so mean? Don't hurt the beetles!
To calculate this,
We know that energy is 1 photon
E = hc/wavelenth
wavelength of 10.0 m
Solution:
h = 6.626 x 10^-34 Jsec
C = 2.9979 x 10^8 m/sec
E = 6.626 10^-34 * 2.9979 10^8 / 10 = 1.9864 10^-26J
Then, the number of photons is computed by:
n = 1000 / 1.9864 10^-26 = 5.04 10^28 photons
Answer:
You need to add 400mL of water
Explanation:
500mL = 5 M HCI That means that if you divide both sides by 5
100mL = 1 M HCI If you need ot get rid of 4 M HCI then you add 400 mL of water because that is what it is equal to
