Explanation:

[tex]from \: boyle's \: law \\ P _{1} V _{1} = P _{2} V _{2} \\ 35 \times 11.2 = 64 \times V _{2} \\ V _{2} = \frac{35 \times 11.2}{64} \\ V _{2} = 6.125 \: L[/tex]

The volume of the gas is 6.13 l if it is increased to a pressure of 64.0 mm Hg.

Boyle's law is a gas law which states that at constant temperature, the pressure of a given quantity of a gas varies inversely with its volume occupied by it.  

According to the Boyle's Law:

PV = constant

Thus,

[tex]P_{1}V_{1} = P_{2} V_{2}[/tex]

where,

[tex]P_{1}[/tex] is the initial pressure

[tex]V_{1}[/tex] is the initial volume

[tex]P_{2}[/tex] is the final pressure

[tex]V_{2}[/tex] is the final volume

Now, put the values in above equation we get

[tex]P_{1} V_{1} = P_{2} V_{2}[/tex]

35.0 × 11.2 = 64.0 × [tex]V_{2}[/tex]

392 = 64.0 × [tex]V_{2}[/tex]

[tex]V_{2}[/tex] = [tex]\frac{392}{64}[/tex]

[tex]V_{2}[/tex] = 6.13 L

Thus, the volume of the gas is 6.13 l if it is increased to a pressure of 64.0 mm Hg.

A few years back I back in 8th grade I head somewhat of a scream underwater, at first I was amazed at the sound but I suddenly realized how physically possible, the only way to make noise under water is to breath in the water and that can drown you, as I heard this I almost immeaditetly bolted out of the water and saw someone either trying to destroy their lungs themselves or being uneducated, they ended up stopping after a bunch of people started staring at them.

Answer:

C The water accepts a proton from the hydrogen chloride.

Explanation:

The equation given in this question where hydrogen chloride reacts with water is as follows:

HCI + H2O → CI- + H3O+

From this equation, hydrogen chloride (HCl) loses or donates hydrogen ion (H+) or proton to water (H2O), which accepts it to become hydronium ion. Hence, in a nutshell, water (H2O) accepts a proton (H+) from the hydrogen chloride (HCl) in this reaction.

Answer:

Carbon dioxide is held together by weak intermolecular forces (only London dispersion LD) and is a non-polar molecule. Because of this weak attraction, it exists as a gas. Water on the other hand is polar (dipole forces DP), and has a stronger hydrogen bond existing within it (in addition to LD). This makes it attract itself more than say carbon dioxide molecules, so it commonly exists as a liquid. Finally, salt like water is polar, and has ionic bonds that are even stronger than a hydrogen bond. This makes salt have a great attraction to itself, sticking together as a solid because its molecules cant easily be broken up.

Explanation:

These are the strongest intermolecular forces ranked from strongest to weakest.

1. Network Covalent

2. Ionic

3. Hydrogen Bonding

4. Dipole Dipole

Explanation:

The magnetic dipole axis of the earth is tilted about 11½° from the rotation axis. This means the magnetic north pole and the geographic north pole are not in the same place. ...

They are also not the sam ehtings :

Magnetic axis is the straight line joining the two poles of a magnet (as the magnetic poles of the earth)

Rotational axis i think is the straight line that joines the north and the south pole of the  .earth .... NOTE: The earth is a bit tilted....

look at the daigram for reference.

The rotational axis of the Earth and its magnetic axis are separated by 11.5 degrees and are not one and the same.

The rotational axis is an imaginary line or axis through which any object rotates and revolves.

The angular momentum vector of the object is divided by the angular momentum magnitude to find the rotational axis of an object.

The rotational axis of the earth is 23.5 degrees.

Thus, the correct option is A.

Answer:

a. 2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O

b. 1 mol MgCl2/ 1 mol Mg(OH)2

1 mol MgCl2/ 2 mol HCI

Explanation:

a. The reaction of an acid (HCl) with a base (Mg(OH)2) produce water (H2O) and the salt (MgCl2):

_HCl + _Mg(OH)2 → _MgCl2 + _H2O

To balance the Cl:

2HCl + _Mg(OH)2 → _MgCl2 + _H2O

To balance the oxygen:

2HCl + _Mg(OH)2 → _MgCl2 + 2H2O

The reaction is now balanced

2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O

b. Based on the balanced reaction, the moles ratios are:

1 mol MgCl2/ 1 mol Mg(OH)2

1 mol MgCl2/ 2 mol HCI

Answer:

No 1 is fission

while no 2 is fusion

Fission is splitting on nucleus while fusion is forming heavier nucleus with nuclei

The kind of nuclear reaction that occurs in the following reactions are:

i. nuclear fission

ii. nuclear fusion.

Nuclear reactions are that reactions in which a nucleus or nuclei collides with subatomic particles to form another, different nucleus. There are two types of collisions. Nuclear fission and nuclear fusion.

Nuclear fission is a process when large nuclei split and create small, numerous nuclei. It happens due to the instability of an atom. It split into two daughter nuclei.

Nuclear fusion is a process in which two or more small nuclei combine to create a large, heavy nucleus. The process releases a large amount of energy or can be absorbed.

Thus, the processes are i. nuclear fission

ii. nuclear fusion.

Answer:

Final pressure = 362.7 Pa

Explanation:

Given that,

Initial volume, V₁ = 930 ml

Initial pressure P₁ = 156 Pa

Final volume, V₂ = 400 mL

We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.

[tex]V\propto \dfrac{1}{P}\\\\\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}\\\\P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{930\times 156}{400}\\\\P_2=362.7\ Pa[/tex]

So, the final pressure is equal to 362.7 Pa.

Answer:

6.25 gram

Explanation:

Applying,

R = R'([tex]2^{a/n}[/tex])................ Equation 1

Where R = Original mass of the isotope, R' = mass of the isotope left after disintegration, a = Total time, n = half life.

make R' the subject of the equation

R' = R/([tex]2^{a/n}[/tex])................. Equation 2

From the question,

Given: R = 100 gram, a = 20 munites, n = 5 minutes.

Substitute these values into equation 2

R' = 100/([tex]2^{20/5}[/tex])

R' = 100/[tex]2^{4}[/tex]

R' = 100/16

R' = 6.25 gram

Reason:- The Mechanism of Diffusion In the case of food coloring in water, the water is the solvent while the food coloring is the solute. Once they've mixed, they make a solution. Diffusion takes time, though how much time depends on the kinetic energy of the molecules randomly bouncing among each other.
