Which things below would help make an ecosystem more biodiverse? O Having a very large population of a species O Having a large community of organisms O Lots of different traits in a species Not having seasons
Answers
• An ecosystem refers to multiple species
• A large population of one species is a decent answer but not the best because more species would have more diverse genetics
• Lots of traits in one species is basically the same as the above bullet point
• Not having seasons could help but not necessarily
• So our best answer is a large community of organisms

How many joules of energy are required to melt 423g of water at 0°C?
Answers
Answer: hope this helps mark me BRAINLEST plz ;)
Explanation:42. Practice Problem How many joules of energy are required to vaporize 423g of water at 100oC and 1atmosphere of pressure. q = mHv m = 423 g Hv = 2260 J/gq = (423g) (2260J/g) = 955,980 J = 956 43. Table T – Heat Formulas
The amount of heat needed to melt 423 g of water at 0°C is 141282 J
The heat required to melt water can be obtained by using the following formula:
Q = mLQ is the heat required.
L is the latent heat of fusion (334 J/g)
m is the mass.
With the above formula, we can obtain the heat required to melt the water as illustrated below:
Mass of water (m) = 423 g
Latent heat of fusion (L) = 334 J/g
Heat (Q) required =?Q = mL
Q = 423 × 334
Q = 141282 JTherefore, the amount of heat needed to melt 423 g of water at 0°C is 141282 J

Convert 4.36 x 10 square 25 molecules of CH3OH to moles.
Answers
Answer:
72.43 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where 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
[tex]n = \frac{4.36 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 72.425249[/tex]
We have the final answer as
72.43 molesHope this helps you

Why do atoms exchange or share electrons during bonding?
to obtain a full outer electron shell
to attract an ion with the opposite charge
to become neutral
to have eight inner level electrons
Answers
Answer:
to obtain a full outer shell
Explanation:
The atoms of some elements share electrons because this gives them a full valence shell. ... If atoms can't achieve a full outer shell by transferring electrons, they resort to sharing. In this way, each atom can count the shared electrons as part of its own valence shell. This sharing of electrons is covalent bonding.
Atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.
What is Chemical bonding?Chemical bonding may be defined as a type of interaction that is significantly accomplished through the association of atoms into molecules, ions, crystals, and other stable species that make up familiar substances.
According to the context of this question, the atoms of some elements typically transfer their electrons to the other elements in order to achieve a fully filled outermost shell.
If they do not have a tendency of transferring, they follow a different mechanism of sharing their electrons. The sharing of electrons gives rise to the formation of covalent bonding.
Therefore, atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

1.5 of potassium ioxcide in 150cm^3 of solution
Answers
Answer:
Explanation:
I'm not sure what is being asked, not the units of "1.5." I don't know of potassium "ioxicide." Was "dioxide" intended?
I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).
The molar mass of K2O, potassium dioxide, is 94.2 g/mole. 1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O. The definition of Molar is moles/liter. So take the moles of K2O and divide by the liters, which is 0.150L in this case.
(0.0159 moles K2)/0.150 L = 0.106 M K2O

Give the correct order of apparatus (Crucible, Filter funnel, Test tube, Dropper, Spatula) to show the correct arrangement that can be used to prepare and investigate the nature of pH of a sample of onion solution.
Answers
Answer:
Is it Crucible,Test tube,Dropper,Filter funnel, Spatula
Explanation:
The laboratory apparatus is used to experiment with the chemicals and to hold them. To prepare and investigate the pH of the onion sample apparatus required are the crucible, test tube, dropper, filter funnel, and spatula.
What is pH?pH is the measurement of the hydrogen or the hydroxide ion concentration in the solution to determine the alkaline or acidic nature of the substance.
The pH of the onion solution can be determined by experimenting with the help of the laboratory apparatus and reagents. A crucible is a container that can withstand high temperatures.
A test tube is a glassware used to hold the substance or chemical in it. Similarly, a dropper is used to draw liquids. The filter funnel separates the filtrate or the solution. A spatula can be used to remove or add the substance.
Therefore, the correct order of the apparatus is the crucible, test tube, dropper, filter funnel, and spatula.
