Ionic is the answer. This is because lithium has a positive charge, while chlorine has a negative charge, meaning the compound doesn’t necessarily have an overall charge.
The formula for molarity is: mol/L. so it would be 2.0 mol/ 6.0 L.
the answer is: .33 M
hope this helps!
Answer:
14.5 g silver
Explanation:
This is a problem using the stoichiometry of the reaction. First thing we need is the balanced equation:
Zn + 2 AgNO3 ----------------------- 2 Ag + Zn(NO3)2
We know that 14.6 g of Zn did not reacted, then we can calculate the amount of Zn reacted and do the calculation given the above reaction.
amount Zn reacted: 19.0 -14.6 g Zn = 4.4 g Zn
atomic weight of Zn: 65.37 g/mol
mol Zn reacted: 4.4 g Zn x ( 1 mol Zn/ 65.37 g Zn) = 0.067 mol Zn
We know from the balanced equation that moles of Ag are produced from 1 mol Zn therefore the mol of Ag produced are:
0.067 mol Zn x 2 mol Ag/ 1mol Zn = 0.135 mol Ag
and the mass of silver then will be given by multiplying by the atomic weight of silver:
0.135 mol Ag x 107.9 g/mol = 14.5 g Ag
Answer:
No
Explanation:
It is not easier for an atom to lose a proton or a neutron because these particles are held together by very strong nuclear forces within the atom.
Protons are positively charged particles
Neutrons do not carry any charges.
In the nucleus of an atom, both protons and neutrons can be found.
As with both particles, the very strong attractive force makes them very difficult to remove in ordinary chemical reactions.
Nuclear forces are one of the strongest forces that keeps an atom especially the nucleus together. Only in nuclear reactions to we encounter a situation where nuclear materials are changed, in that regard the properties of the atom also changes.
