Remember, electronegativity decreases down a group (vertically) and increases across a period (horizontally) on the periodic table. :)
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.

Answer:
Cancel out CO because it appears as a reactant in one intermediate reaction and a product in the other intermediate reaction.
Explanation:
The CO appears twice hence in he intermediate reaction it only forms path of the enabling reagents and it further reacts to form the final product. Accounting for the CO in the intermediate reaction that undergoes further reaction will impact on the stoichiometry of the reaction.
This is asking for the absolute humidity. So if the relative humidity is 65 % and the air temperature is 30 then we need to have in mind the barometric pressure which will be 760. The humidity in the air will be 0.020 kg/m3. In order to know this we calculate it eith the mass of water vapour in a unit volume of air. This is a measure of the actual water vapour content of the air. the for mula would go like this: AH = Mv / V.
Explanation:
F = k.m1.m2/r²
m1 and m2: masses of objects
r: distance between the objects
k: a constant
