Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is the name of the liquid state of H2O at standard conditions for temperature and pressure.
Answer:
E.
Explanation:
Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.
At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.
ABC are reactants their concentration should decrease over time
DE are products, they should increase as reaction goes on.
Protons goes in the blank. the word can be used for both.
Answer:
Dynamic
Explanation:
When rocks grind and squeeze past each other, dynamic metamorphism can occur.
Answer:
The correct answers are "occur as Earth rotates through areas where ocean water bulges", "form due to the gravitational pull of the moon and Sun" and "occur on a predictable schedule".
Explanation:
Tides are defined as the rise and fall of the sea level that are formed due to the gravitational pull of the moon and Sun, however, the moon exerts a more stronger influence since it is much closer to the Earth. Tides occur as Earth rotates through areas where ocean water bulges, actually, Earth rotation makes an inertia effect that also contributes to tides force. Tides occur on a predictable schedule. For instance, it is known that coastal areas experience two low tides and two high tides every lunar day (24 hours and 50 minutes).
