Answer : Yes, the concentrated is a catalyst in this reaction.
Explanation :
Catalyst : It is a substance that increase the rate of chemical reaction but it is not consumed by the reaction. That means catalyst can be recovered chemically at the end of the reaction.
The given balanced chemical reaction is,
From the balanced chemical reaction we conclude that the amount of present in the reactant side are remains same as the amount of present in the product side. That means the amount of is not consumed by the reaction and it can be recovered chemically at the end of the reaction.
Hence, yes, concentrated is a catalyst in this reaction.

Answer:
0.024M
Explanation:
Data obtained from the question include:
C1 = 6M
V1 = 2mL
C2 =?
V2 = 500mL
The molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
6 x 2 = C2 x 500
Divide both side by 500
C2 = (6 x 2) /500
C2 = 0.024M
The molarity of the diluted solution is 0.024M
Answer:
The molarity is 0.024 mol / L
Explanation:
Molarity = Number of moles / Volume of solution
= (6.0 mol/L x 2.0 x L) / 0.500 L
= 0.024 mol / L
Answer : The volume of gas formed at STP is 7.86 liters.
Explanation :
The balanced chemical reaction will be:
First we have to calculate the moles of .
Molar mass of Al = 27 g/mole
Now we have to calculate the moles of gas.
From the reaction we conclude that,
As, 2 mole of react to give 3 mole of
So, 0.234 moles of react to give moles of
Now we have to calculate the volume of gas formed at STP.
As, 1 mole of gas contains 22.4 L volume of gas
So, 0.351 mole of gas contains volume of gas
Therefore, the volume of gas formed at STP is 7.86 liters.
well in this case its percipitation rain hail sleet snow itll set like water after so long it dissolve itll turn into gases
Answer:
Buoyancy.
Explanation:
Buoyancy is a force created by the water that is displaced by an object. It is directly proportional to the amount of water that is being displaced by an object.
Hence, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
The unit of measurement for the buoyancy of an object is Newton (N).
(2) gamma radiation, alpha particle, beta particle
(3) positron, alpha particle, neutron
(4) neutron, positron, alpha particle
Answer: Option (4) is the correct answer.
Explanation:
An alpha particle is basically a helium nucleus and it contains 2 protons and 2 neutrons. Symbol of an alpha particle is or .
This means that an alpha particle carries a +2 charge.
A positron is a small particle which contains a +1 charge. And, a positron is represent by the symbol .
A neutron is a sub-atomic particle present inside the nucleus of an atom. Charge on a neutron is 0.
A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.
Symbol of a gamma particle is . Hence, charge on a gamma particle is also 0.
Therefore, we can conclude that group of nuclear emissions from neutron, positron, alpha particle is listed in order of increasing charge.
The group of nuclear emissions is listed in order of increasing charge is neutron, positron and alpha particle and the correct option is option 4.
Nuclear emissions refer to the particles and radiation that are emitted from the nucleus of an atom during a nuclear reaction or radioactive decay. These emissions include alpha particles, beta particles, gamma radiation, positrons, and neutrons.
Thus, the ideal selection is option 4.
