Answer:
Asexual reproduction .
Explanation:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent.

Briefly describe each of the suns layers. I’ll give brainless
Answer: The inner layers are the Core, Radiative Zone and Convection Zone.
The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.
Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.
The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.
The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

For the balanced equation shown below, how many moles of H2O will react with 9 moles of N2?
N2 + 4H2O --> 2H2O2 + N2H4
Answer:
36 mole of H20
Explanation:
N2 + 4H2O --> 2H2O2 + N2H4
H20 : N2
4 : 1
x : 9
cross multiplication
so,
= 9x4/1 = 36 mole of H20

How many moles of sulfuric acid (H2SO4) are present in 500.0 mL of 0.15 M H2SO4 solution?
Answer:
Number of moles = 0.075 mol
Explanation:
Volume = 500.0 mL = 0.5 (Converting to L by dividing by 1000)
Molarity = 0.15 M
Number of moles = ?
The relationship between the quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Molarity * Volume
Number of moles = 0.15 * 0.5
Number of moles = 0.075 mol

Equimolar solutions of the following were prepared in water separately. Which one of the solution will record the highest pH?
o CaCl2
SrCl 2
Ba(NO 2 )2
MgCl2
Answer:
Ba(NO2)2
Explanation:
Anything that contains calcium comes from a strong acid. Nitrous oxide (NO2) is a weak acid, therefore the salt it makes is less acidic than the rest --> the highest pH :)
What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

What does it mean to be limiting or excess? (Limiting Reactant)
Answer:
Find the limiting reagent by calculating and comparing the amount of product each reactant will produce. Balance the chemical equation for the chemical reaction. The reactant that produces a lesser amount of product is the limiting reagent. The reactant that produces a larger amount of product is the excess reagent.

The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.
What is noble gas configuration ?The electron configuration of noble gases would be known as that of the noble gas configuration. The propensity of chemical elements to gain stability forms the foundation of all chemical reactions. Chemical formation frequently leads to an entire electronic configuration approximating a noble gas for several main group elements.

1 In what type orbital are the outer electrons of the atoms of the elements of Group 1 (IA) and Group 2 (IIA)?
Answer:
s orbital
Explanation:
The elements of Group 1 (IA) and Group 2 (IIA) have one and two electrons in their outermost shells respectively.
For the elements in group Group 1 (IA), the general outer electron configuration is ns1. This last electron is accommodated within an s orbital.
For the elements in Group 2 (IIA), the two outermost electrons are accommodated in an ns orbital, hence the answer.

Can i titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer
Answer:
No, I don't think so at least
Explanation:
In chemistry, you do calculations to find the concentration of a solution with another solution of KNOWN concentration. Without concentrations of either solution, were would you get values from? Where would you start? :3
You can not titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer.
Titration involves the standardization of unknown solution using a standard solution. By this definition, titration must involve a standard solution.
Since the two unknown solutions are not standardized, we can never get a meaningful answer because we can not be able to perform any calculation unless we have a standard solution.

Explanation:
How much energy is released when 67.04g of phosphorous is reacted with 10.20g of chlorine? ___ P + ___ Cl2 ___ PCl3 ΔH = -574 kJ
Answer:
26.78 kJ
Explanation:
To solve the problem, we have to first write the stoichiometric coefficients in the chemical equation:
2P + 3Cl₂ → 2PCl₃
With these coefficients, we have the same number of atoms of each chemical element on both sides: 2 atoms of P, 6 atoms of Cl.
According to the equation, 2 moles of phosphorous (P) react with 3 moles of chlorine (Cl₂), and 574 kJ of energy are released. We have to figure out which is the limiting reactant. For this, we convert the mass into moles by using the molar mass(MM):
MM(P) = 30.9 g/mol
67.04 g P/(30.9 g/mol) = 2.17 mol P
MM(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol
10.20 g Cl₂/(70.8 g/mol) = 0.14 mol Cl₂
Now, we multiply the actual moles of P (the amount we have for the reaction) by the stoichiometric ratio given by the chemical equation (3 mol Cl₂/2 mol P):
2.17 mol P x (3 mol Cl₂/2 mol P) = 3.25 mol Cl₂
To completely react 67.04 g P, we need 3.25 mol of Cl₂, and we have only 0.14 moles of Cl₂, so the limiting reactant is Cl₂.
Now, we use the limiting reactant to calculate the energy released from the reaction. The energy released per mole of Cl₂ is:
ΔH/(3 mol Cl₂) = -574 kJ/3 mol Cl₂= 191.3 kJ/mol Cl₂
Finally, we multiply the energy released per mole of Cl₂ by the number of moles of Cl₂ we have:
0.14 mol Cl₂ x 191.3 kJ/mol Cl₂ = 26.78 kJ
