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.
As for #5, it's mixed at the end of my answer, but just remember the spring equinox marks the change from 24 hours of darkness to 24 hours of daylight at Earth's poles .
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.

Which set up would correctly complete the work for determining how many moles of NaOH will be produced if 10.5 grams of water (H2O) is used?
Answer:
B: 2 mol NaOH/2 mol H2O
Explanation:
The reaction equation is;
H2SO4 + 2NaOH = Na2SO4 + 2H20
Now, to know how many moles of NaOH will be produced for 10.5 grams of water (H2O) used, and since the molar mass of H2O is 18.02 g/mol and number of moles attached to H2O and NaOH in the reaction are both 2 we will have;
10.5g H2O × 1 mol H2O/18.02 g H2O × 2 mol NaOH/2 mol H2O
Thus correct answer is option B

I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

How many grams of potassium chloride (KCl) can be produced from 180.6 g of chlorine (Cl2)?
Answer:
379.79 g of KCl
Explanation:
The balanced equation for the reaction is given below:
Cl₂ + 2KBr —> Br₂ + 2KCl
Next, we shall determine the mass of Cl₂ that reacted and the mass of KCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Cl₂ = 70.90 g/mol
Mass of Cl₂ from the balanced equation = 1 × 70.90 = 70.90 g
Molar mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 × 74.55 = 149.1 g
SUMMARY:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Finally, we shall determine the mass of KCl produced by the reaction of 180.6 g of Cl₂. This can be obtained as follow:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Therefore, 180.6 g of Cl₂ will react to produce = (180.6 × 149.1)/70.90 = 379.79 g of KCl.
Thus, 379.79 g of KCl were obtained from the reaction.

Equilibrium constant Kp for the reaction P4(s) + 6Cl2(g) 4PCl3(l) Kp = 1/ P6Cl2 Kp = P4Cl3/ P6P4 Kp = P4Cl3/ (P6P4) (P6Cl2) Kp = 1/ (P6P4) (P6Cl2)
Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]
For the given chemical reaction:
[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]
The expression for [tex]K_p[/tex] in terms of gaseous is written as:
[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.

How many grams of carbon dioxide would 6.0E25 molecules be?
Answer:
4383.28 g
Explanation:
First we'll need to convert molecules into moles, we can do so using Avogadro's number:
6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 molesThen we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:
99.62 moles CO₂ * 44 g/mol = 4383.28 gi need help guysssss

_ 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 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.
