what happens to the electronegatity when you go from top to bottom on the periodic table?
Answer:
It decreases
Explanation:
As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.
Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.what are some natural resources that are limited on earth

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure?
Answer:
133.3atm
Explanation:
Given parameters:
Initial volume = 400ft³
Final volume = 3ft³
Initial pressure = 1atm
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states;
Insert parameters and solve;
1 x 400 = P₂ x 3
P₂ = 133.3atm

A transformer has 150 turns in its primary coil and 50 turns in its secondary coil. If the input voltage is 12 V, what is the output voltage?
Answer:
36V
Explanation:
Given parameters:
Number of turns in primary coil = 150turns
Secondary coil turn = 50turns.
Input voltage = 12V
Unknown:
Output voltage = ?
Solution:
For this transformer problem, we use the expression;
[tex]\frac{N_{s} }{N_{p} }[/tex] = [tex]\frac{V_{s} }{V_{p} }[/tex]
Insert the parameters and solve;
Ns is the number of secondary turns
Np is the number of primary turns
Vs is the secondary voltage
Vp is the secondary voltage
Insert the parameters and solve;
[tex]\frac{150}{50}[/tex] = Output voltage / 12
Output voltage = 12 x 3 = 36V

The atoms of some elements can be made
radioactive by
1)placing them in a magnetic field
2)bombarding them with high-energy
particles
3)separating them into their isotopes
4)heating them to a high temperature
Answer:
I think 4 I got it right on edg but i duno if its the same
Explanation:
The atoms of some elements can be made radioactive by: bombarding them with high energy particles: Choice 3.
Definition:
Radioactivity is a process, (spontaneous) by which the nucleus of an unstable atom loses energy by emitting radiation which may include alpha particles, beta particles, gamma rays and conversion electrons, otherwise known as high energy electrons.However, radioactivity is observed as a natural occurring process, the phenomenon can also be artificially induced typically via the bombarding atoms of a specific element by radiating particles, thus creating new atoms.Read more:

Water flows through a pipe at a rate of 620 gallons every 5 1/2 minutes expressed this rate of flow and cups per second
The rate of flow of Water flows through a pipe will be 30 cups per second.
What is the rate of flow?The distance covered by the particle or the body in an hour is called the rate of flow. It is a scalar quantity. It is the ratio of gallons to time.
We know that the speed formula
Rate of flow = Gallons/Time
Water flows through a pipe at a rate of 620 gallons every 5 1/2 minutes expressed at this rate of flow and cups per second.
We know that in one gallon, there are 16 cups.
5.5 minutes = 330 seconds
The rate of flow will be
Rate of flow = (620 x 16) / 330
Rate of flow = 30 cups per second
The rate of flow of Water flows through a pipe will be 30 cups per second.
More about the rate of flow link is given below.

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
Answer:
NaOH(aq)
Explanation:
NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)
Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

Identify the type of reaction depicted below:
2SO2(g)
+
O2(g) --> 2SO3(g)
Answer:
Combination reaction
Explanation:
In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.
In this case, a reaction is depicted as follows:
2SO2(g) + O2(g) --> 2SO3(g)
In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.

The element is
sulfur
. This can be determined by looking at the number of
protons
. The element has a valence shell of
16
and
6
valence electrons.
Answer:
This can be determined by looking at the number of protons.
Explanation:
The atomic number which is the number of protons is the best indicator of what an element is.
Based on the number of protons in an atom, elements are arranged in a definite grouping on the periodic table.
This because, atoms do not readily give off their protons so, it is a good measure of the type of atom one might be dealing with.

one example of a question that science would not be able to test. Then, explain how it could be changed into a testable question. i need a whole sentence and i will give all my points it's science
Answer:
Explanation:
A testable question is the one which can be answered using experiment and research. A non-testable question is the one which cannot be answered using experimental trials.
Example:
Non-testable: Which is more better ice-cream or chips?
Testable: Which is more better nutritionally ice-cream or chips?
Here, in the non-testable question no parameter was given for comparision and analysis hence, it cannot be tested experimentally. Whereas, in the testable question nutritional quality is to be compared between the two food items.
