How many electrons are present in one neon
atom?
Answer: 10 electrons
That means there are 10 electrons in a neon atom. Looking at the picture, you can see there are two electrons in shell one and eight in shell two. Because shell two has eight electrons it is now full.
Explanation: Hopefully this helped!
Subscripts are used in a chemical formula to show the number of atoms of each element.
True or False.
If endothermic means that the temperature increases and exothermic means it decreases, it 64 degrees to 64 degrees (it stayed the same) endothermic or exothermic?
Answer:
The answer is none of them.
Explanation:
I did the study guide...Also, if it has no change, it is neither.
In Natural selection, individuals whose unique characteristics are well-suited for an environment tend to survive and produce more offspring. true or false? i need this help!right now!
Answer:
True
Explanation:
True. If an animal has attributes to it that help it survive better in an environment, it will survive better than its counterparts who do not have this attribute. More survival = More offspring
Answer:
True.
Explanation:
It's called survival of the fittest. Animals are genetically supposed to be well suited to their environment and if they aren't, they die out.

What are valence electrons? How do you quickly determine the number of valence electrons an
atom has?
Answer:
Electrons that arent electrons
Explanation:
I teach chem
Answer:
Valence electrons are the electrons found in the highest and main energy level of the atom, being these responsible for the interaction between atoms of different species or between atoms of the same species. You can quickly determine these by looking at a periodic table like this one... Which is where the roman numbers come in and show the valence electrons. (THIS TABLE IS IN SPANISH, I hope you still recognize the symbols.) :))
In chemical reactions, what does the law of conservation of mass mean?
Group of answer choices
Matter is not created nor destroyed.
The total mass of the products is greater than the total mass of the reactants.
The total mass of the reactants is less that the total mass of the products.
Matter is not changed.
Answer
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Calculate the number of molecules in 2.00 moles H2S.
Express your answer numerically in molecules.
Answer:
The answer is
1.204 × 10²⁴ moleculesExplanation:
The number of molecules can be found by using the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2 × 6.02 × 10²³
We have the final answer as
1.204 × 10²⁴ moleculesHope this helps you

All of the following changes to a metal are physical changes except_____.
bending
melting
rusting
polishing
Answer:
D)Polishing..
Answer:
Wouldn't it be rusting
Explanation:
Melting and bending are physical changes so is polishing. so rusting is the only choice, for metal to rust wouldn't it need a chemical change.
The vaporization of Br2 from the liquid to the gas state requires 7.4 kcal/mol. write a reaction showing heat as a product or reactant
Answer:
Br₂(l) + ΔV → Br₂(g)
Explanation:
When a chemical or phase change occurs during a chemical process some heat is absorbed or released. For the process of vaporization of a substance, the heat (Usually required) is ΔV (How many energy is required for the process occurs).
In the vaporization of Br2 there are required 7.4kcal/mol, Δv. The reaction is:
Br₂(l) + ΔV → Br₂(g)A 10.151 g sample of window cleaner containing ammonia was diluted with 39.466 mL of water. Then 4.373 g of solution was titrated with 14.22 mL of 0.1063 M HCl to reach a bromocresol green end point. Find the weight percent of NH3 (FM 17.031) in the cleaner.
Answer:
2.878 (w/w)%
Explanation:
The reaction of NH3 with HCl is:
NH3 + HCl → NH4Cl
That means 1 mole of ammonia reacts per mole of HCl. The moles of HCl that reacts = Moles of ammonia are:
14.22mL = 0.01422L * (0.1063mol HCl / L) = 0.001512 moles HCl = Moles ammonia
In mass:
0.001512 moles NH3 * (17.031g / mol) = 0.02574g of NH3 in the solution.
The concentration in weight percent of the diluted solution is:
0.02574g of NH3 / 4.373g * 100 = 0.5887 (w/w)%
This is the concentration of the diluted solution that was diluted from 10.151g to 10.151g + 39.466g = 49.617g
-Assuming density of water = 1g/mL-
The solution was diluted:
49.617g / 10.151g = 4.888 times.
That means the concentration of NH3 in the original cleaner is:
0.5887 (w/w)% * 4.888 =
2.878 (w/w)%can someone please help me? i will give brainliest

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?
Answer:
92.65256 cm^3
Explanation:
To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?
Answer:
I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.
Answer:
H2SO4 + 2KOH => K2SO4 + 2H2O
Explanation:
The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.
The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.
sulfuric acid + potassium hydroxide => potassium sulfate + water
So, the balanced equation for this reaction is as follows:
H2SO4 + 2KOH => K2SO4 + 2H2O
Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".
