Remember the acronym "Oil Rig". Oxidation is loss, Reduction is gain of electrons. Calcium is losing electrons so it's an oxidation reaction.

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.

4) Find the mass of 1.46 mol of Al2(SO4)3.
ddd [48]

Answer:

1.46mol of Al2(SO4)3 weights 499.5 grams

Explanation:

First we will find the gram formula mass of Al2(SO4)3.

Al * 2 = 26.98 g/mol * 2 = 53.96 g

SO4 * 3 = 96.06 g/mol * 3 = 288.18

53.96 + 288.18 = 342.14 g

That is the mass of 1 mol of AL2(SO4)3.

Now we will multiply 342.14g by 1.46.

342.14 * 1.46 = 499.5244 g

Or ... 499.5 g
