1. Yes because the ocean takes in the carbon dioxide from the air. This causes more acid in the water, this makes it hard to make shells and skeletons for the seal life that need them.
2.No because it isn't harmful unless it builds up. But there is people who work to clean and limit the chances of build-up.
Hope this helps :)
Answer:
In diamond the carbon atoms are covalently bonded as flat sheets
In silicon(IV) dioxide the silicon and oxygen atoms are covalently bonded in flat sheets
The structure of copper includes a lattice of positive ions
Explanation:
Diamond and silicon(IV) dioxide are covalent network solids. Covalent network solids are made up of atoms joined to one another by covalent bonds to form a giant lattice, The solids are hard and have a very high melting point. They do not conduct electricity. So, for both diamond and SiO2, atoms are covalently bonded to yield flat sheets in a covalent bonded network solid.
Copper is a metallic substance having metallic bonds, a metallic crystal consists of positive ions and a cloud of electrons.
Answer:
-3
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Protons have a positive (+) charge
- Neutrons have a neutral (0) charge
- Electrons have a negative (-) charge
Explanation:
<u>Step 1: Define</u>
7 protons, 9 neutrons, 10 electrons.
+7, +0, -10
<u>Step 2: FInd charge</u>
7 + 0 - 10 = -3
Answer:
The correct answer is - it provided water, food, transportation, and excellent, fertile soil for growing food.
Explanation:
People of Egypt moved to the northern Nile river due to various reasons. In this region, the soil is very excellent and helps in growing crops as the soil is fertile due to the appropriate climate and water resources.
It is aso helps in selling and transporting the products as it was a trade route at the time. As it is known Egypt has almost no rainfall so the only way crops can get water is through the Nile river.
