Hello!
The balanced chemical equation for the reaction between sodium and chlorine is the following:
2Na + Cl₂ → 2NaClTo know the mass of Sodium Chloride produced, we are going to use the following conversion factor to go from grams of Chlorine gas to grams of Sodium Chloride:
So,
56,007 g of NaCl are produced
Have a nice day!
A.) 3 H2SO4 + 2 Al > Al2(SO4)3 + 3 H2
6 H+ +3 S +12 O +2 Al> 2 Al + 3S + 12O + 6H+
This one is balanced, with 6 H, 3 S, 12 O, and 2 Al on both sides.
B.) 2KCl + Pb(NO3)2 > KNO3 + PbCl2
2K + 2Cl + Pb + 2N +6 O > 1 K + 1 N+ 3 O + Pb + 2 Cl
This one is not balanced as there is 2 K, 6 O and 2 N on the reactants side but only 1 K, 3 O, and 1 N on the products side.
Therefore, only A.) is balanced
Answer:
G : pent-2-ene
H : H2o
I : pent-1-ene
Explanation:
The OH would combine with H from H-O4SH
Then the O attached to the carbon would get detached taking the electrons with it, leaving carbon an positively charged.
The OH now combined with H-O4SH would take the H away from the acid forming H2O and (O4SH)-
The negative ion of (O4SH)- would then take the H from positively charged C forming the sulphuric acid back. It does not take the electrons with it*
Which is why the carbon can then form a double bond with the excess electron (2). the major product would be pent-2-ene and minor would be pent-1-ene.
This is because pent-2-ene is more stable than pent-1-ene. (Due to secondary carbon and primary carbon factor)
This is the whole backstage story though.
If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
If the container has heat insulation, the rate of temperature drops will decrease too. Water specific heat is higher than the air, so it will need much more energy to increase water temperature.
