Answer:  D. In the ocean

A watershed can be defined as regions of land where all surface water drains into the same place. It is a land that is occupied with water drained from interconnected  rivers, and lakes.  These drainage streams may aggregate in the ocean.

According to the above information the open watershed system likely to dispense off tritium in the ocean because the open watershed water may flow and combine with other reservoirs of water like ocean.

12 g of powdered magnesium oxide reacts with nitric acid to
galben [10]

Answer:

80.8 g

Explanation:

First, let's write a balanced equation of this reaction

MgO + 2HNO₃ → Mg(NO₃)₂ + H₂O

Now let's convert grams to moles

We gotta find the weight of MgO

24 + 16 = 40 g/mol

12/40 = 0.3 moles of MgO

We can use this to find out how much Magnesium Nitrate will be formed

0.3 x 1 MgO / 1 Mg(NO₃)₂ = 0.3 moles of Magnesium Nitrate formed

Convert moles to grams

Find the weight of Mg(NO₃)₂ but don't forget that 2 subscript acts as a multiplier of whatever is inside that parenthesis.

24 + 14 x 2 + 16 x 3 x 2 = 148 g/mol

148 x 0.3 = 80.8 g

A plant fertilizer contains 15% by mass nitrogen (N). In a container of soluble plant food, there are 12.2 oz of fertilizer. How
ale4655 [162]
51.86 grams would be in the container.

One ounce is an equivalent of 28.34 grams, so times that by 12.2
.
12.2 * 28.34 = 345.75.

Put the percentage into decimal form, so 15% would now be 0.15.

0.15 * 345.75 = 51.86.
