Low tides are located at___
A an C
A an B
B an D
Answer: A and C
Explanation:
Low tides occur in locations at 90 degree angles to the moon. Tidal cycles have the same length as the lunar day, 24 hours and 50 minutes. In this time span, most locations will experience two high tides, when the location is close to and far from the moon, and two low tides. Sides A and C are angled 90 degrees from the moon.
Hence, low tides are located at A and C.
Answer:90 degree angles to the moon.
Explanation:
The temperature at which a solid melts is the same as the temperature at which its liquid form solidifies (true or false)
its false not true................
Answer:
True
Explanation:
This is true because, upon cooling the particles in a liquid loses energy, stops moving and remains constant and the forms a solid.
Therefore we can say the freezing point and melting point occurs at the same temperature

By referring to particles, explain why the white ring formed in the glass tube
Answer:
Ammonia and Hydrogen Chloride.
Explanation:
Assuming this is what you're referring to, Ammonia (NH3) and Hydrogen Chloride(NCI3). The concentrated ammonia (NH3) is placed on a pad in one end of a tube and hydrochloric acid (NCI3) on a pad at the other. Shortly after the gases will begin diffusing far enough to meet, a ring of solid ammonium chloride (NH4Cl) will be formed.

Is oxygen a necessary reactant for an oxidation reaction? Explain
Answer:
So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction).
The oxidation reaction does not require oxygen as a reactant. An atom, molecule, or ion loses one or more electrons during the chemical process of oxidation, increasing its positive charge.
What is oxidation ?When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.
A molecule is said to be oxidized when oxygen is added to it or when hydrogen is taken out of it. Reduction is the process of introducing hydrogen or removing oxygen from a molecule.
An element is oxidized if it loses electrons, which is another definition of oxidation. Any electron acceptor can oxidize an element by taking in the lost electrons, hence oxygen is not a necessary component in oxidation.
The process of converting glucose into ATP requires oxygen. For each glucose, the first step only releases two molecules of ATP.
Thus, The oxidation reaction does not require oxygen as a reactant.

The ___ of a bottle tells you how much liquid it can hold. what is the anewer
Answer:
Volume
Explanation:
Volume is how much of a substance something can hold!
Hope this helped, have a nice day! :)
The word that completes the sentence is "volume."The volume of a bottle refers to how much liquid it can hold, typically measured in liters or milliliters.
Knowing the volume of a bottle is important when you need to measure out or store a certain amount of liquid. Different types of bottles have different capacities, so it's important to check the label or specifications to determine the right size for your needs.
Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.
Thus, the word that completes the sentence is "volume."

What is the sum of the atomic numbers of each element present in the reactants of the given formula?
2 NH3 + H2SO4 → (NH4)2SO4
Answer:
25
Explanation: They all add up to 25 Atoms
The atomic number of nitrogen is 7 and that of oxygen is 8. Atomic number of hydrogen is one and the atomic number of sulphur is 16. Then, the sum of atomic numbers of each element present in the reactants of the given formula is 32.
What is atomic number ?The atomic number of an atom is the number of electrons in its neutral state. This number is equal to the number of protons also. The modern periodic table classify all elements based on their atomic numbers.
The sum of number of protons and neutrons of an element is called its mass number. For the given formula, the elements present are H, O, N and S.
atomic number of H = 1
atomic numebr of N = 7
atomic number of O =8
atomic number of S = 16.
Then ,sum of atomic number s= 1 + 7 + 8 + 16 = 32.
Therefore, the sum of the atomic numbers of each element present in the reactants of the given formula is 32.

When excess potassium hydroxide and H2SeO3 react whats the net ionic reaction for the acid-base rxn
The required net ionic equation is; 2H^+(aq) + 2OH^-(aq)-----> 2H2O(l)
The molecular reaction equation is;
H2SeO3(aq) + 2KOH(aq) -----> K2SeO3(aq) + 2H2O(l)
The complete ionic equation is;
2H^+(aq) + SeO3^2-(aq) + 2K^+(aq) + 2OH^-(aq)-----> 2K^+(aq) + SeO3^2-(aq) + 2H2O(l)
Net ionic equation;
2H^+(aq) + 2OH^-(aq)-----> 2H2O(l)
We can clearly see that this is a neutralization reaction hence water is the product of the net ionic equation.

Silicon dioxide is a solid at room temperature and methanol is a liquid. What substance has the higher melting point?
Answer:
methanol because it is liquid at room temperature which means that it melts at a lower temperature
Silicon dioxide is a solid at room temperature and methanol is a liquid. Silicon dioxide has a higher melting point than methanol because silicon dioxide is solid, and with increasing temperature, it will melt.
What is a melting point?Melting point is that point or temperature at which the solid items are converted into liquid, and it changes their atoms and the atoms lose their compactness.
Here, two compounds are given, Silicon dioxide and methanol, the first one is solid at room temperature, so it will need more temperature to melt down and methanol is still liquid at room temperature, so its melting point is low.
Thus, methanol is a liquid while silicon dioxide is a solid at ambient temperature. Because silicon dioxide is a solid and melts at greater temperatures, it has a higher melting point than methanol.
