science of love
,EXPLANATION:
The initial happy feelings of being in love is stimulated by 3 chemicals in the brain: noradrenaline that stimulates adrenaline production causing that racing heart and sweaty palms; dopamine, the feel-good chemical; and phenylethylamine that is released when we're near our crush, giving us butterflies in our tummies.

Wind
Explanation:
the other ones you can only use once
Explanation:
kclo3- 39+35.5+16*3=122.5
molar mass = 122.5
mass = 14.0g
volume= 100cm3
solubility in mol/dm3 or molarity = ?
but we know that
no of moles = solubility in mol/dm3×vol in cm3
---------------------------------------------
1000
no of moles = mass
---------
molar mass
mass\molar mass= solubility in mol/dm3 *vol in cm3/ 1000
14.0/122.5=x * 100/1000
solubility =0.875 mol/dm3
Solid cobalt (iii) oxide react with solid carbon to form solid cobalt and carbon ( iv) oxide gas
word equation is written as follows
cobalt (iii)oxide+carbon ---->cobalt +carbon (IV) oxide
the balanced chemical equation is written as follows
2Co2o3 +3c --->4Co +3 co2
