If you start with 0.020 g of Mg, how many moles of H2 will you make if the reaction is complete?
irina [24]

If one starts with 0.020 g of Mg, 0.0008 moles of H2 would be made if the reaction is complete.

Going by the balanced equation of reaction in the image, 1 mole of Mg will produce 1 mole of H2 in a complete reaction.

If 0.020 g of Mg is started with:

mole of Mg = mass/molar mass

                        = 0.020/24.3

                            = 0.0008 moles

Since the mole of Mg to H2 is 1:1, thus, 0.0008 moles of H2 will also be made from the reaction.

How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentenc
alisha [4.7K]

Answer:

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Even though it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization
