Physical changes can be reversed and chemical changes can’t be reversed. A physical property is a characteristic which can be identified without changing the substance but to identify a chemical property, you do have to change the substance.
Answer:
0.24
Explanation:
We are given that
Rate constant for A=
Rate constant for B,k'=0.0750/s
We have to find the value of equilibrium constant for the reaction
Equilibrium constant, for k=
Using the formula
Hence, the value of the equilibrium constant for the reaction
at this temperature=0.24
Soda ash which is also referred to as sodium carbonate with a chemical formula (NaCO3) has the following chemical formula
The melting point of 851 degrees
The molecular weight of 105.98
Its density at 25 degrees is =2.53 g/cm^3
Its specific heat capacity at 25 degrees = 0.249 cal/gm/ 0c
Answer:
electrons
Electrons are negatively charged particles that orbit the nucleus. The number of electrons depends on the element and it is an ion or not
True
cohesion is the tendency for the same type of molecules to stick together!
