Answer:
0.925 mole
Explanation:
From the question given, the following were obtained:
Volume = 1.0L
Molarity = 0.925 M
Number of mole of Nickel (II) chloride =?
Molarity is simply defined as the mole of solute per unit litre of the solution.
It is represented mathematically as:
Molarity = mole /Volume
With the above equation, we can easily find the mole of Nickel (II) chloride present in the solution as follow:
Molarity = mole /Volume
0.925 = mole / 1
Mole = 0.925 x 1
Mole of Nickel (II) chloride = 0.925 mole
Answer:
Option B and D
Explanation:
The Gibb's free energy also referred to as the gibb's function represented with letter G. it is the amount of useful work obtained from a system at constant temperature and pressure. The standard gibb's free energy on the other hand is a state function represented as Delta-G, as it depends on the initial and final states of the system.
A feasible way to synthesize the product entails the spontaneity of the reaction.
The spontaneity of a reaction is explained by the standard gibb's free energy.
If Delta-G = -ve ( the reaction is spontaneous)
if Delta -G = +ve ( the reaction is non-spontaneous)
if Delta-G = 0 ( the reaction is at equilibrium)
Hence the option (B and D) with negative Gibb's free energy are the reaction that are spontaneous.
Answer:
i would say red
Explanation:
im learning about this right now lol actually. <3
Answer:
See explanation
Explanation:
The structure of ethylene is shown in the image attached. The two carbon atoms have a double covalent bond between them.
The two carbon atoms are sp2 hybridized. The bond between them is a covalent bond, there is one pi bond and one sigma bond between the carbon atoms. Between carbon and hydrogen, there are covalent bonds also. The covalent bonds are sigma bonds.
The pi bonds between carbon atoms is weaker than the sigma bonds between the carbon atoms. This is because, the side-by-side overlap the p orbitals in a pi bond is less effective than the end-to-end overlap of a sigma bond.
Answer:
mNaCl = mNa + mCl
mNa = 20g
mCl = mCl2/2 = 30/2 = 15g
mNaCl= 20+15 = 35g
