highest energy level for lithium
QUESTION :
highest energy level for lithiumANSWER :
There are 2 electrons on the first energy level and 1 electron on the second. Explain that the first energy level can only have 2 electrons so the next electron in lithium is on the next (second) level. Explain that neon has 10 protons and 10 electrons.The equation for the synthesis of water is given below.

describe the properties of the compound in sugar, and Compare the properties of the
compound with the properties of the elements that comprise sugar. How do you explain the difference?
Answer: Sodium chloride is an ionic solid, and when it dissolves in water, its individual sodium and chloride ions are dissociated from one another. Sugar molecules, on the other hand, maintain the bonds between their constituent atoms when dissolved, and thus remain as whole molecules in the solution.
Explanation: Here's why: Salt is about 25% more dense than sugar. Therefore a teaspoon of salt weighs more than a teaspoon of sugar by almost 25%. Your dissolving test would not be accurate because you would be starting out with a larger mass of salt than sugar.
Can skin help animals see?
Answer:
Explanation:
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition.
CAN SOMEONE ANSWER ME!! 5-6
Answer:
As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.
What is the chemical reaction taking place?
Answer: Synthesis (of phosphorous and oxygen to form tetraphosphorous decaoxide)
Explanation:
Al(s) + NiSO4(aq)
Balance
Answer:
[tex]2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni[/tex]
Explanation:
This reaction type is a single replacement. The format of a single replacement is:
[tex]A+BC --> B+AC[/tex]
A= Al
B= Ni
C= SO
The coefficient 3 for Ni would become a subscript for AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

Describe how greater distance affects the appearance of an object’s size and brightness
Answer:
Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ... Each of their effective temperatures results in a different brightness for the object. The quasar, however, is very far away, and so appears dim.

mole equations please help me :(
Answer:
A. 0.48mol O2
Explanation:
The balanced equation is given as follows:
2CH3OH + 3O2 → 2CO2 + 4H2O
This shows that 2moles of CH3OH is required to react with 3 moles of O2
If 0.32 moles of CH3OH are reacted, then;
0.32 × 3/2 moles of O2 is required
= 0.96/2
= 0.48mol of O2

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2

If 5 times a number is increased by 4 the result is 19 find the lest possible number that satisfies theses condition
Answer: 3
Explanation: 5 times a number would be 5x, then increase that by 4 is 5x+4. The problem then says 5x + 4 ≥ 19. If we solve for x then we get x ≥ 3 so x has to be greater than or equal to 3, so the smallest number it could be is 3. You can even try any number smaller than 3 and see it doesn't work. even something like 2.9

HELpPPPPppp!!!!!! will mark brainless
Answer:
A
Explanation:
This is because in the graph shown line A has a quite greater impact of refraction than line B .
Hence, we can conclude that line A has the greater reaction at a faster rate.
