Answer:
in the nucleus of an atom
Explanation:
The distance of 0.704 kilometers is equivalent to 704 meters when converted, using the conversion factor that 1 kilometer equals to 1000 meters.
To convert the distance from kilometers to meters, we utilize the known fact that 1 kilometer is equivalent to 1000 meters. Thus, to get the equivalent of 0.704 kilometers to meters, simply multiply the given distance by 1000.
So, 0.704 kilometers * 1000 = 704 meters.
This means that this particular distance or length is the same as 704 meters when converted to meters from kilometers.

b. increasing the pressure of the solution
c. decreasing the size of the salt particles
d. increasing the temperature of the solution
The following which would not affect the rate of dissolution of salt in a beaker of water is:
The dissolution of salt in a beaker of water increases when an external force stirs it which makes it move from its initial position to a new position.
As a result of this, we can see that if there is a decrease in the size of salt in the beaker of water, there would also be a change in the dissolution of salt in the water.
However, increasing the pressure of the solution would not affect the rate of dissolution of salt in the beaker of water.
Therefore, the correct answer is option B

Answer: Option (b) is the correct answer.
Explanation:
When we stir a solution then its particles start to move from their initial position leading to more number of collisions between them.
As a result, rate of dissolution increases with stirring.
When we increase the pressure then no change in dissolution occurs because in liquids and solids pressure does not play any role is solubility or dissolution.
When we decrease the size of solute particles then there occurs an increase in surface area of solute. Hence, due to this more number of solute particles are able to come in contact with the solvent.
This will lead to more number of collisions. Therefore, rate of dissolution will increase.
Also, when we increase the temperature then molecules of solution will gain kinetic energy leading to more number of collisions which will eventually lead to increase in rate of dissolution.
Thus, we can conclude that out of the given options increasing the pressure of the solution would not affect the rate of dissolution of salt in a beaker of water.
To solve this we must be knowing each and every concept related to Enthalpy. Therefore, 10,148KJ/mol is the ΔH for formation for the reaction 16CO(g) + 18HO(g) 2CH(l) + 25O(g)
Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances. Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance.
The balanced equation for the given chemical reaction can be given as
16CO(g) + 18HO(g) 2CH(l) + 25O(g)
ΔH for formation= 10,148KJ/mol
Therefore, 10,148KJ/mol is the ΔH for formation for the reaction 16CO(g) + 18HO(g) 2CH(l) + 25O(g)
