The stage in which the hair begins to destroy itself as it disconnects from the
papilla is called?

Answer:

Below

Explanation:

In a chemical reaction, per the law of conservation of mass, no atoms or subatomic particles will be created or destroyed; for example, H2O2 will decompose into H2 and O2, meaning no matter was created or destroyed.

Answer:

A

Explanation:

The trick here is to know what the conservation of mass means.

It means that no matter what happens and how much change there is, the mass of the carbons on the reactants = the mass of the carbons on the products.

That's exactly what A says.

The setup above is used to collect hydrogen gas

Both filtration and distillation are useful ,methods to purify or separate components of a mixture. To collect soluble gas such as ammonia the best method is distillation. Thus setup 2 is better for collection of solute.

Distillation is the process of separation of compounds using  heat and condenser. The mixture is first boiled to the boiling point of solvent. When it is heated the solvent such as water passes from the beaker on which the mixture is taken.

The steam of the solvent is then cooled in the condenser tube and then liquid is collected to a second beaker. Therefore, the solute remains in the first beaker and can be collected.

Using filtration, we can only separate solution with insoluble solutes. Using filter paper the solid from the solution can be separated out.

First set up shows the filtration method  which is not applicable for collecting soluble gas like ammonia. Therefore, the second setup that is distillation is better to collect soluble gases.

I have solution to your question

Nitrogen is 7th element in periodic table. It contains 7 electrons in which are 2 are inner electrons and 5 are outer electrons. Here N is in -3 oxidation state. Thus, it is having 8 valence electrons.

Isotopes of are atoms with same atomic number and different mass numbers. Almost every elements have isotopes but some of them are unstable in nature.

Atoms forms ions when they lose or gain electrons. Wen they lose electrons, they form positive ions called cations. When they gain electrons they form negative ions or anions.

Nitrogen is 7th element in periodic table. It has 7 electrons out which 2 are inner electrons and 5 are valence electrons. N needs 3 more electrons to attain octet. Thus it gains 3 electrons and forms its 3 - oxidation state.

Thus N in -3 oxidation state have 8 valence electrons.

Explanation:

Answer:

0.1045 L (4 s.f.)

Explanation:

The molecular weight, [tex]M_{r}[/tex], of calcium chloride is

[tex]M_{r}(\mathrm{CaCl_{2}}) \ = \ A_{r}(\mathrm{Ca}) \ + \ 2 \times A_{r}(\mathrm{Cl}) \ = \ (40 \ + \ 2 \times 35.5) \ \mathrm{g \ mol^{-1}} \ = \ 111 \ \mathrm{g \ mol^{-1}}[/tex], where [tex]A_{r}[/tex] is the atomic weight of the respective elements.

To calculate the number of moles (n) of calcium chloride present in 58g,

[tex]n_{\mathrm{CaCl_{2}}} \ = \ mass \ \div \ molecular \ weight \ (M_{r}) \\ \\ \-\hspace{1.13cm} = \ 58g \ \div \ 111 \ \mathrm{g \ mol^{-1}} \\ \\ \-\hspace{1.13cm} = \ 0.5225 \ \mathrm{mol \ of \ CaCl_{2}}[/tex]

Since molarity, M, is defined as the number of moles (n) of the solute per liters of a solution (L), hence to get the volume (V) required to make up a 5 molar solution is

[tex]n \ = \ M \times V \\ \\ V \-\hspace{0.05cm} = \ \displaystyle\frac{n}{M} \\ \\ V \-\hspace{0.05cm} = \displaystyle \frac{0.5225 \ \mathrm{mol}}{5 \ \mathrm{mol \ L^{-1}}} \\ \\ V \-\hspace{0.05cm} = \ 0.1045 \ \mathrm{L}[/tex]

Answer:

These weather conditions are consistent with droughts, often characterized by hot, dry, weather. When this is the case, it is important to conserve water and use it only for necessities. Garden sprinklers are not essential, so their use can be sacrificed in order to provide more crucial services, such as drinking water. This rule has been put in place in order to avoid water shortages and energy crises, events that would be even more damaging during an emergency.

Explanation:

this is a chemistry question ???

anyway, it is clearly A, as seatbelts try to counteract the inertia a moving body (our bodies riding in a car) has, when the environment (the car) of this body is suddenly coming to a stop.

this inertia would otherwise try to move the body still forward resulting in a headfirst crash into and often through the windshield. which causes much more damage to the body than the bruises caused by the pressure of the seatbelts against the body counteracting the body's inertia.

but also clearly, all 3 laws play a role.

the force with which the moving body has to deal when smashing into the windshield and potentially then other objects outside the car is described by the second law.

and for any action (crash) there are corresponding reactions (like the conversion of the crash energy into some absorbing reaction : damaged soft and hard tissue in the human body, crumbled car bodies,...).

MORSE CODE ISN'T THAT FUN AND I'M USING A TRANSLATOR TOO SO

Explanation:

Answer: Neutral Xe atom

It will take the Ne gas approximately 1.2 s to equilibrate between the two sides.

We know that the time taken for a gas to diffuse is dependent on the molar mass of the gas. This is one of the interpretations of Graham's law of diffusion in gases. Thus, Let;

t1 = time taken for Rn to equilibrate = 4.0 s

t2 = time taken for Ne to equilibrate = ?

M1 = molar mass of Rn = 222g/mol

M2 = molar mass of Ne = 20 g/mol

Using

t1/t2 = √M1/M2

4/t2 = √222/20

4/t2 = 3.33

t2 = 4/3.33

t2 = 1.2 seconds
