How does knowing the meaning of prefix-trans help you remember what happens to light that strikes a translucent object ?
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.
What molecules tend to have high kinetic energy and low intermolecular forces.
Answer: Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together. As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no "time" to move around, the particles have more "time" to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction). The three states of matter are: Solids: The strong bonds between molecules make solids rigid and very difficult to deform. Liquids: The relatively weak bonds between molecules allow liquids to be deformed without effort.

What is the bond order for a single covalent bond?
Answer:
We typically represent covalent bonds with a dash ( - ) between the atoms. This indicates a single bond. Ex: Cl - Cl
Single bond, double bond, triple bond.
Explanation:
We call it a single covalent bond because the atoms are sharing a single pair of electrons.
Answer: If you have this question: The bond order for a single covalent bond is ____.

What is the molecule that formed between B and F?
Answer:
BF3
Explanation:
For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

When glucose is totally oxidized to CO2 and H2O, how many ATP molecules are made by oxidative phosphorylation out of a maximum yield of how many ATP molecules?
Answer: 26 out of 30.
Explanation:
Out of 30 ATP molecules, 26 are produced from maximum oxidative phosphorylation production. Two more come from glycolysis and two more are from the citric acid cycle.
To power other cellular processes, ATP captures and releases chemical energy obtained from the breakdown of food molecules.
In any chemical process, the matter is neither lost nor gained. *
reaction
conservation of matter
covalent bonds
physical change
In any chemical process, the matter is neither lost nor gained according to conservation of matter. Therefore, the correct option is option B.
What is matter?Matter is any material that has weight and occupies space by having volume in classical physics as well as general chemistry. All common items that can be felt are ultimately constituted of atoms, which are composed of colliding subatomic particles, therefore "matter" typically comprises atoms and everything made up of them, as well as any particles that act as if they both rest weight and volume.
It does not, however, contain massless particles like photons or even other energy phenomena and waves like light or heat. There are numerous states of matter (also known as phases). In any chemical process, the matter is neither lost nor gained according to conservation of matter.
Therefore, the correct option is option B.

A ball is moving at a speed of 6.70 m/s. If the kinetic energy of the ball is 3.10 J, what is the mass of the ball?
Answer:
0.14 kgExplanation:
The mass of the ball can be found by using the formula
[tex]m = \frac{2k}{ {v}^{2} } \\ [/tex]
v is the velocity
k is the kinetic energy
From the question we have
[tex]m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...[/tex]
We have the final answer as

which is a greater threat to a mountain ecosystem: a beetle that kills coniferous trees or a wolf thats hunts and eats deer?
Answer:
Explanation:
The mountain ecosystems are characterized by coniferous tree species such as pinus, firs, and spruces and species such as deers, bears, and wolves.
A beetle that kills coniferous trees would be a greater threat to the ecosystem than a wolf that hunts and eat deer because the dominant trees in the ecosystem are conifers. Hence, a beetle that kills coniferous trees might end up killing the dominant tree species in the ecosystem and this will gravely affect other plant and animal species within the ecosystem.
Wolves and deers have their niche in the mountain ecosystem already and hence, their populations are naturally limited by limiting factors of the environment. Hence, a wolf that hunts and eats deers would be of a lesser threat to the mountain ecosystem.
You are eating dinner with your familiy one night. Your little brother (Who is a disgusting monster ) asked if you likes "seafood?" When you said yes, He proceeded to show you his chewed up, or "See Food". Did a chemical reaction take place, yes or no? What evidence or lack of evidence do you have to support your answer?
Answer:
yes eating the food involves both physical and chemical changes. The chewing of food is a physical change, while the mixing of saliva with food triggers chemical reactions
Explanation:
Once the food mixes with the saliva in our mouth, chemical reactions start taking place in the food, leading to its breakdown and changes in its chemical composition. An evidence of the chemical changes is the taste that we feel when we eat something sweet or sour etc.

The general equation shown is a reaction that is an
a. exothermic decomposition
b. endothermic decomposition
c. endothermic synthesis
d. exothermic synthesis
Answer:
b. endothermic decomposition
Explanation:
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
Endothermic reactions:
The type of reactions in which energy is absorbed are called endothermic reactions.
In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.
For example:
C + H₂O + 131 kj/mol → CO + H₂
Thus, in given reaction energy is added and AB compound is decomposed to give A and B so this reaction is endothermic decomposition.
determine the number of charged particles in nucleus of calcium atom then deduce the number of electrons
NUCLEAR CHARGE (20+)
ATOMIC MASS (40 amu)
given the relative charge of a proton =1+\ m1nucleon=1amu
Answer:
detail is given below.
Explanation:
The charged particles of nucleus are protons while neutrons are neutral having no charge.
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus.
Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.
one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.
While the atomic number is 20.

Please if you don't know don't answer
Answer:
Mass = 50kg, a = 20m/sec^2
F = MA
F = 50 * 20
F = 1000N
F = MA
650 = M * 10
M = 650/10 = 65kg
The phenomenon of weightlessness occurs when there is no force of support on your body. when your body is effectively in free fall, accelerating downward at the acceleration of gravity, then you are not being supported.
