Answer: -
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Explanation: -
The mass number for ¹³C = 13
The atomic number for ¹³C = 6
Number of electrons present in ¹³C = atomic number = 6
Number of protons present in ¹³C = atomic number = 6
Number of neutrons present in ¹³C = mass number - atomic number = 13 - 6 = 7
For ¹³C ⁻ ion,
Number of electrons present = 6 + 1 = 7
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Answer:
When the concentration of a reactant increases, there will be more chemical present. Due to more reactant particles moving together, more collisions are allowed to happen and with that, the rate of the reaction is increased. So, the higher the concentration of reactants, the faster the reaction rate will be.

Answer:
The pressure of 0.5 mole of nitrogen gas=
Given:
Moles of nitrogen gas=0.5mole
Volume of nitrogen gas=5L
Temperature of nitrogen gas=203K
To Find:
Pressure of 0.5g mole of nitrogen gas
<u>Step by Step by Explanation:</u>
Formula used for calculating the pressure of a gas is achieved through ideal gas equation
According to Ideal Gas;
From this above equation, pressure can be calculated as
Where P=Pressure of the gas
N=number of moles=0.5moles
R=Gas constant
V=Volume of nitrogen gas in litres=5L
T=Temperature of nitrogen gas=203K
Substitute all the values in the above equation we get
Result:
Thus the pressure of 0.5 mole of nitrogen gas is <u></u><u>
</u>
Answer:
324.554 K
Explanation:
Which can be converted back to °C by subtracting 273
Once again thus answer can be found using the gas law P1/T1 =P2/T2
Remember to convert to Kelvin before doing the calculations by adding 273
Answer:
Valence electrons are the number of electrons in an outer shell of an atom that can participate in forming chemical bonds with other atoms.
