Answer:
22.49 g of NH3
Explanation:
The balanced equation for this would be:
3H₂+N₂ → 2NH₃
So let's take note of this:
We will need 3 moles of H₂ to produce 2 moles of NH₃.
Now let us convert:
First we determine the molar mass of H2:
Element:
number of atoms x molar mass
H = 2 x 1.01 g/mol = 2.02 g/mol
Let's see how many moles of H2 there are in 4.00g
Now we can see how many moles of NH₃ we can make given the ratio and convert it again to grams by getting the molar mass of NH₃:
This means that with 1.98 moles of H₂, we produce 1.32 moles of NH₃
So let's get the molar mass of NH₃ so we can convert it to grams:
N = 1 x 14.01 = 14.01
H = 3 x 1.01 = 3.03
17.04g/mol
Answer:
Demand for spinach is elastic.
Explanation:
The price floor, which is maintained by the United States, is the minimum price for selling the goods. This price is set above the equilibrium price, which results in excess supply while demand for the same goods remains constant.
Since the prices for spinach cannot be set lower than the price floor and the policy is decreasing the revenue output for spinach farmers then this probably means that the prices are set too high which has decreased the demand for spinach. This means that the demand for spinach is elastic.

Answer:
105
Explanation:
base year = 2016
cost of market basket of goods in base year = $2,000
CPI for base year = 100
year 2018
cost of market basket of goods in 2018 = $2,100
CPI for 2018 = (cost of basket of goods in 2018 / cost of basket of goods in base year) x 100 = ($2,100 / $2,000) x 100 = 105
