Answer:
No
Explanation:
It is one of those harsh realities that no matter how hard we try to connect people to their roots aka make them understand that everything is interconnected like the breathe you throw out is used by plants in photosynthesis, the O2 plants give is used by us. Living beings and Non-living beings are all connected and most humans know about this. But, when it comes time for earning the $$$, people's judgements are often clouded by their greed hence no matter how hard we try to make people understand we are all connected and that they should take care of the environment more, they will likely treat the environment as they always have been: to serve their financial and selfish needs.
TLDR: People are selfish hence probably will not treat environment with more care even if we educate them about our interconnectedness.
I NEED HELP DESPERATELY!!!!!!!!!!!!!!!!!! If 20 waves pass a fixed point in 5 seconds, the frequency of the wave is....What???
Answer:
Frequency, f = 4 Hz
Explanation:
We have,
Number of waves passing a fixed point are 20
Time, t = 5 seconds
It is required to find the frequency of the wave. Frequency of a wave is defined as the number of waves passing through a point per second. Its mathematical form is given by :
[tex]f=\dfrac{n}{t}\\\\f=\dfrac{20}{5}\\\\f=4\ Hz[/tex]
So, the frequency of the wave is 4 Hz.
5. Do you think oppositional or symbiotic relationships are more beneficial to an ecosystem? Justify
your answer.
Answer:
I think they are beneficial for the life of those symbiotic organisms that require yes or yes from another to be able to live.
Although an ecosystem could not be carried out if only this relationship would occur, since symbiotic relationships we have an organism where it needs another to live and even removes the necessary nutrients for it, that is why the chain should continue with other types of relationships .
Explanation:
The symbiosis is defined as "Intimate association of organisms of different species to mutually benefit in their vital development" that is why adequate coexistence between these living organisms is needed, otherwise this phenomenon would not occur.
A very good example of the symbiosis is: Bees and plants where the bee is the pollinating agent of the plant so that it continues to reproduce and the plant is the bee's food source.
Therefore I believe that the development of this type of relationship is VITAL, and very fundamental, otherwise I do not know if an ecosystem or a balanced ecosystem could be carried out.

Scientists classify the parts of a phospholipid molecule according to their chemical properties. What are these parts? an acidic head and basic tails hydrophilic tails and a hydrophobic head a hydrophilic head and hydrophobic tails acidic tails and a basic head
Answer: hydrophilic head and hydrophobic tails
Explanation:
A phospholipid consists of glycerol molecule, 2 fatty acids, and 1 phosphate group that is replaced by alcohol. In the phosphate group the polar head is negatively charged and hydrophilic in nature, whereas the fatty acid chain is nonpolar tails, that are hydrophobic. The tails are hydrophobic which face the inside and away from water.
Answer:
hydrophilic head and hydrophobic tails

Select all of the items that are true about a sample of water vapor at 101°C as it cools.
Its temperature will fall continuously until it condensed into a liquid.
Its temperature will fall steadily until reaching 100°C.
The molecules of water gain potential energy.
Its temperature will remain at 100°C until all the vapor condenses.
Answer:
D. Its temperature will remain 100 C until all the vapours condenses
Explanation:
Heat absorbed by a substance to change the state of matter is known as latent heat. This heat is utilized to break the bonds between atoms of the substance so that they can undergo phase change.
So, when water boils at 100 degree Celsius then temperature will remain constant unless and until all the water changes into vapor. As it is the latent heat that breaks the bonds between hydrogen and oxygen atoms of water so that liquid state can change into gaseous state.
Since latent heat is a hidden heat, that is why, it does not get reflected and there is no change in temperature due to it.
Thus, we can conclude that it is true that temperature will remain at 100°C until all the vapor condenses for a sample of water vapor at 101°C as it cools.

Balance the following reaction CS2+Cl2. CCl4+S2Cl2
Answer:
CS₂ + 3Cl₂ ⇒ CCl₄ + S₂Cl₂
Explanation:
This one is relatively simple. When we take inventory of both sides, we see 1 Carbon, 2 Sulfurs, and 2 Chlorines on the reactant side, and 1 Carbon, 2 Sulfurs, and 6 Chlorines on the product side. Since we have Cl₂ on the left and we want 6 on the left, let's add a coefficient of 3 to Cl₂. This balances everything out! Final answer: CS₂ + 3Cl₂ ⇒ CCl₄ + S₂Cl₂. Hope this helps!
The compound butanol has the following structural formula.
Which of these is a structural isomer of butanol?
Answer:
Option B
Explanation:
A structural isomer of an organic compound refers to a compound that has the same molecular formula, but a different arrangement of atoms in the carbon chain.
Butanol has the molecular formula C4H9OH. We can now explore the options to see if any of them have the same molecular formula.
Option A has no oxygen in it, so we can rule it out
Option B has 4 carbon atoms, 9 hydrogen atoms and 1 oxygen atom as well as single Chain branches. This makes it the structural isomer of Butanol ( C4H9OH).
Option C has only 3 carbon atoms which rules it out as being an isomer.

We can find the heat of reaction by using the Hess' Law. This is done by using this formula:
∑(Hf,products) -∑(Hf,reactants) = Heat of reaction
where Hf is the heat of formation. According to literature, these are the heats of formation for each of the compounds in the reaction:
NaHCO3: -947.68 kJ/mol
Na2CO3: -1130.94 kJ/mol
CO2: -393.51 kJ/mol
H2O: -241.8 kJ/mol
Applying Hess' Law:
[1(-1130.94) + 1(-241.82)] + 1(-393.51)] - [2(-947.68)] = 129.09 kJ
Thus, the heat of reaction is 129.09 kJ/mol NaHCO3. Since there is 1.96 mol of NaHCO3, the total heat of reaction is 253.02 kJ.

In terms of disorder and energy, systems in nature have a tendency to undergo changes toward
less disorder and lower
energy
less disorder and higher energy
greater disorder and lower energy
greater disorder and higher energy
Answer:
Option C is correct
Explanation:
Entropy is defined as the randomness in a system. In nature, a system tends to have high entropy. The higher the entropy , the spontaneous the reactions would be. As a system loses energy, it becomes more ordered and less random. Hence, as the reaction proceeds in a system, the system has higher energy/entropy and less order.
Hence, option c is correct
In the hydrolysis of ethyl ethanoate, what will happen when the reaction is catalysed by an alkali?

How many ml of solution are needed to make a 5.78 M solution with 2.98 moles of CaO?
Answer:
515.6 mL
Explanation:
Please see the step-by-step solution in the picture attached below.
Hope this answer can help you. Have a nice day!
The number of mL of the solution needed to make a 5.78 M solution with 2.98 moles of CaO is 516 mL.
The number of moles that is present in a liter of solution is regarded to be the Molarity of the solution that is measured in mol/L.
[tex]\mathbf{Molarity = \dfrac{number\ of \ moles(n)}{Volume \ (in \ liters)}}[/tex]
[tex]\mathbf{Molarity = \dfrac{2.98 moles }{5.78 \ mol/ L}}[/tex]
Molarity = 0.51557 L
If 1 Liter of solution contains 1000 mL, then 0.51557 L will contain:
= 0.516 × 1000 mL
= 516 mL of solution.
Therefore, we can conclude that the number of mL of the solution needed to make a 5.78 M solution with 2.98 moles of CaO is 516 mL.

What is an atom?
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
