Petrochemicals are separated into 3 groups: Olefins, Aromatics, and Synthesis Gas.
Olefins: Ethelyne (Plastic Products), Propelyne (Plastic Products), and Butadiene (Synthetic Rubber)
Aromatics: Benzene (Dyes), Toluene (Polyurethane), and Xylenes (Synthetic Fibers)
Synthesis Gas: Ammonia (Fertilizer Urea) and Methanol (Chemical intermediate)
Answer:
Destruction of rocks at convergent boundaries
Explanation:
Duuuuuuuuude. Dude.
Let's think for a sec, because this confused me.
Acid rain is chemical weathering. It has acid in it, so it weathers rocks. (Ewwww.)
Frost wedging is a major duh, because frost can weather rocks.
Oxidation reactions are a yes yes because it becomes oxidized.

Answer:</h3>
318.405 g
<h3>
Explanation:</h3>
We are given;
- Volume of K₃PO₄ solution to be prepared as 750.0 mL or 0.75 L
- Molarity of the solution to be prepared as 2.00 M
We are required to determine the mass of K₃PO₄ to be measured.
<h3>Step 1: Determine the number of moles of K₃PO₄</h3>
Molarity = Moles ÷ Volume
Rearranging the formula;
Number of moles = Molarity × Volume
Therefore;
Moles of K₃PO₄ = 2.00 M × 0.75 L
= 1.5 moles
<h3>Step 2: Determine the mass of K₃PO₄ to be measured</h3>
Mass = Number of moles × Molar mass
Molar mass of K₃PO₄ = 212.27 g/mol
Therefore;
Mass of K₃PO₄ = 1.5 moles × 212.27 g/mol
= 318.405 g
Therefore, the mass of K₃PO₄ that should be weighed is 318.405 g
Answer: All up to you
Explanation: This is all up to your choice for me I would have chosen #1 but choose one that you think is easier.
Answer:
Isotopes are atoms with the same number of protons, but different numbers of neutrons.
Explanation:
Ex.
Ne 20/10
Ne 21/10
Ne 22/10
*the number of protons in an atom must stay the same or the element itself will change drastically
