Answer:
hope this helps :)
Explanation:
for the first one, you can look at the periodic table and look at the atomic number and it will show you how many protons there are giving you the answer because protons and electrons are equal in a pure element
a- carbon
b- neon
c- boron
d- oxygen
e- helium
f- hydrogen
g- lithium
h- beryllium
i- nitrogen
1- sulfur
2- S
3- 16
4- 32.066
5- 16
6- 16
7- 16.066
8- draw circles and put 16 dots like on the other page and in the middle put 16 nuetrons and electrons
9- 6 i think
Answer:
Another name for ethanol can be ethyl alcohol, drinking alcohol or commonly called as alcohol.
Explanation:
The Ethanol is a simple alcohol which responds to this formula C2H6O.
You can also writes it as C2H5OH and as CH3-CH2-OH.
It is the principal active ingredient found in alcoholic drinks (for example in beer,vine,whisky,etc).
It is a volatile,flammable and colorless liquid.
1. Magnesium atoms also have a slightly smaller radius than sodium atoms, and so the delocalised electrons are closer to the nuclei.
2. Sodium has higher melting point than potassium because of stronger metallic bonding .
3. Potassium are very soft metal can be very easily cut with a knife
4. Increase of resistance in metals. Therefore the mobility of electrons decreases and causes decrease in conductivity.
5.To increase strength, increase corrosion resistance, or reduce costs.
6. All metals have low ionization energies and are relatively electropositive, and so they lose electrons fairly easily.
7. All the group 1 metals are reactive, but they get more reactive as you go down the group, so potassium is more reactive than sodium.
it is much more efficient and environmentally conscious.
Answer : Combustion reactions are those reactions which includes reacting with the oxygen along with the reactant.
Here, the reactant is cooking fat.
So when a long chain hydrocarbon which is cooking fat here reacts with oxygen the products obtained are carbon dioxide and water molecule.
One mole of fat reacts with 70 moles of oxygen and gives 51 moles of carbon dioxide and 44 moles of water molecule.
