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!

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

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.

Answer:

Aspirin, 9 carbon atoms

Explanation:

(would really appreciate the brainliest)

Aspirin is a compound which has most carbon atoms that is it has 9 carbon atoms.

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.

Answer:

253.02 kJ.

Explanation:

The balanced reaction for the decomposition of baking soda is

2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)

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.

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.

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.

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.

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

C) electrons are transferred from one atom to another in both types of bonds

Explanation:

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.
