Use the drop-down menus to seled the correct responses to each question about ocean zones

chubhunter [2.5K]

Answer:

Intertidal zone

Neritic zone

Open-ocean zone

Note: the correct questions are found below;

In which zone do you find marshes and mangrove forests?

In which zone are plankton plentiful, providing plenty of food for the fish that live there?

In which zone would you find very little plant or animal life compared to other zones?

Explanation:

The intertidal zone, sometimes called the littoral zone, is the area of the marine shoreline that is exposed to air at low tide, and covered with seawater when the tide is high. Intertidal zonation refers to the tendency of plants and animals to form distinct communities between the high and low tide lines. Some microclimates in the littoral zone are moderated by local features and larger plants such as mangroves.

The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor.

Due to the abundant supply of sunlight and nutrients such as plankton in this zone, it is the most productive ocean zone supporting the vast majority of marine life.

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.

The active ingredient in aspirin is acetylsalicylic acid (MW = 180.2 g/mol). An aspirin tablet was dissolved in

Mashcka [7]

Answer:

1214 mg

Explanation:

Data given

Volume of NaOH solution (V) = 14.85 mL

Molarity of NaOH solution (M) = 0.100 M NaOH.

Amount of acetylsalicylic acid = ?

Molecular weight = 180.2 g/mol

Solution:

It is a acid base titration

As equal amount of NaOH will neutralize equal amount of acetylsalicylic acid.

First find the moles of NaOH

As we know

M = moles of solute / 1 L x volume of solution

Rearrange and modify the above equation

moles of NaOH = M of NaOH x 1 L / volume of NaOH solution

Put values in above equation

moles of NaOH = 0.100 M x 1 L / 14.85 mL

moles of NaOH = 0.0067 moles

Now find to find the weight of acetylsalicylic acid

equal amount of NaOH will neutralize equal amount of acetylsalicylic acid.

moles of acetylsalicylic acid = moles of NaOH.......... (1)

As we know

no. of moles = mass in g / molar mass

So,

The modified form of equation 1 will be

mass in g / molar mass (acetylsalicylic acid) = moles of NaOH

Put values in above equation

mass in g / 180.2 g/mol = 0.0067 moles

Rearrange the above equation

mass of acetylsalicylic acid = 0.0067 moles x 180.2 g/mol

mass of acetylsalicylic acid = 1.214 g

Convert the grams to milligrams

1 g = 1000 milligram

So,

1.214 g = 1214 mg
