Answer:
AgNO3
Explanation:
Considering the equation:
2 AgNO3(aq) + CuCl2(aq) ––> Cu(NO3)2(aq) + 2 AgCl(s)
2 moles of AgNO3 reacted with 1 mole of CuCl2
divide the moles by two
1 mole of AgNO3 will react with 0.5 mole of CuCl2
then
0.5 mole AgNO3 will react with 0.25 mole of CuCl2 and limiting reagent is the reagent that is consumed when the reaction is completed.
Going by the calculation above the limiting reagent is AgNO3
Answer:
The pressure of N₂ gas in cylinder B when compressed at constant temperature increases due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container.
Explanation:
Gas helps to explain the behavior of gases when one or more of either temperature, volume or pressure is varying while the other variables are kept constant.
In the gas cylinder B, the temperature of the given mass of gas is kept constant, however, the volume is decreased by pushing the movable piston farther into the cylinder. According to the gas law by Robert Boyle, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature. This increase in pressure is due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container. As the cylinder becomes smaller, the gas molecules which were spread out further become more packed closely together, therefore, their frequency of collision increases building up pressure in the process.
Energy was given out in the process as such the reaction must be exothermic given the loss of energy.
<h3>What is a reaction profile?</h3>
The reaction profile shows the the interaction between substances. Now the vertical axes shows the energy while the horizontal axes shows the course of the reaction. The hump at the top of the profile shows the activation energy. The activation energy is the maximum energy that is required for reactants to cross the barrier and become products.
Now we know that the endothermic reaction is one in which energy is taken in while an exothermic reaction is one in which energy is given out.
As such we can see from the graph that the energy of the reactants is greater than that of the products. This implies that energy was given out in the process as such the reaction must be exothermic given the loss of energy.

Answer:
A
Explanation:
I'm doing that rn and that's the answer
The answer is false. It is because the electron structure of
the atom is not determined by using the direct observation of using an x-ray
but rather the usage of theoretical modeling and the emission spectra will be useful
in observing.
