Answer:
Flora and Fauna
Explanation:
therethere are four main regions which are each home to specific landforms, flora and fauna the. These are the upland, the Everglades, the Florida Keys and the Gulf Coast
Answer:
Explanation: Ammonia (NH3) is produced by the reaction of nitrogen gas and hydrogen gas. ... How many grams of fluorine gas are needed to produce 100.00g of AlF3? ... How many molecules of CO2 gas can be produced of 156.24g of benzene, ... (a) If 16.74.g of Fe and 9.0 9 of H2O are allowed to react, how many grams of products.
There is 1 mole of electrons = 96500C and Ca = 40
Ca2+ + 2e --->Ca
Base on the formula above it means that there are 2 moles of electrons to produce 1 mole of calcium.
96500C x 2 = 193000C
193000C electricity produce 40g Calcium
Coulombs = Amps x seconds (28.70A for 12 hours)
= 28.70A x 12 x 60 x 60 C
= 1 239 840 C
This amount of electricity will produce
=1239840 / 193000 x 40g Calcium
= 6.42 x 40 g Calcium
= 256.96 g
So there will be 256.96g of Calcium metal that will be produced in 12 hours.
I think the answer would be the number of electron in pairs that is around the central atom. This is the most general principle in determining structure of a molecule. Electrons are the ones responsible in bonding with other atoms. Hope this helped.
The ones on left are the reactants
