The mussel shell erosion increased by 30 percent points between 1995 and 2020.
<h3>What is erosion?</h3>
Erosion is the washing away of the top layer of a substance or material.
The mussel shell erosion is a type of erosion which occurs in mussel shell as a results of chemical changes that occur on their environment.
The mussel shell erosion is shown on the graph.
Therefore, based on the graph, mussel shell erosion increased by 30 percent points between 1995 and 2020.

<h2>Answer:</h2>
The compound is known as the neurotransmitter or messenger chemicals.
<h3>Explanation:</h3>
- Neurotransmitters are the chemicals a type of messenger which is used to transmit information from one cell to the next cell.
- Some hormones are also known as messenger chemicals.
- The nerve cells are not linked to each other while they are separated from each other by a space known as synapses.
- The electric potential signal is converted into chemical signal by the release of neurotransmitters.
- These neurotransmitter signal next cell to produce equal amount of electric signal in nerve cell.

We produce formaldehyde for medicinal purposes and synthesizing polyester.
Formaldehyde is a compound that is required in about 1.5 ounces in quantity as a normal part of our metabolism.
Also formaldehyde is used as a catalyst in the formation for the synthesis of many polyesters.
Formaldehyde also has many uses such as fungicide, germicide, disinfectant and as a preservative in mortuaries as well as important chemical in medical Laboratories.
In everyday items press fabric paints coating and paper base products also includes formaldehyde.

The grams of N2 that are required to produce 100.0 l of NH3 at STP
At stp 1moles = 22.4 l. what about 100.0 L of NH3
= 100 / 22.4 lx1 moles = 4.46 moles of NH3
write the reacting equation
N2+3H2 =2NH3
by use of mole ratio between N2 to NH3 which is 1:2 the moles of N2 =4.46/2 =2.23 moles of N2
mass = moles x molar mass
= 2.23moles x 28 g/mol = 62.4 grams
