Answer:
One or more number of species which have same number of atomic number but different mass number are called isotopes.
For example, are the isotopes of hydrogen.
So here, the atomic number of each of these isotopes is 1 and have different mass number, that is, 1, 2, 3.
Answer:
The temperature will decrease to 50 K
Explanation:
Step 1: Data given
Temperature = 127 °C = 400 K
Pressure = 2.00 atm
The pressure decreases to 0.25 atm
Volume and number of moles do not change
Step 2: Calculate the new pressure
p1/T1=p2/T2
⇒with p1 = The initial pressure = 2.00 atm
⇒with T1 = The initial temperature = 127 °C = 400 K
⇒with p2 = the new pressure = 0.25 atm
⇒with T2 = the new temperature = TO BE DETERMINED
2.00 atm / 400 K = 0.25 atm / T2
0.005 = 0.25 / T2
T2 = 0.25/0.005
T2 = 50 K
The temperature will decrease to 50 K
Answer:
C. It has the highest rate of reaction. Copper has the highest TSA/V and concentrated nitric acid has huggest num of solute
The correct order of steps during the formation of an ionic bond
- Electrons are transferred
- Ions are attracted to each other
<h3>What is Ionic bonding?</h3>
This is the type of bonding which occurs as result of transfer of electrons
and is also regarded as electrovalent bonding.
When the electrons are transferred , ions form which then gets attracted
to each other and results in the formation of a compound.
