Describe what is ionic bonding and how it happens.

Chemistry
2 answers:
Tems11 [23]2 years ago

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Classify the chemical reaction shown here: CrF3+H3PO4→CrPO4+3HF
Lana71 [14]
The answer 
<span>he chemical reaction CrF3+H3PO4 → CrPO4 + 3HF
the main formula is 
when we observe a reaction as follow:
XY  +  ZT --------------- XT + YZ  
this is classified as double replacement reactions, this means: </span>two ionic compounds exchange ions, producing 2 new ionic compounds.
in our case we have CrF3+H3PO4 → CrPO4 + 3HF
so the classification is double-replacement reactions

What drives an electrolytic cell?
hodyreva [135]

Answer:

C. An external voltage source

Explanation:

An electrolytic cell converts electrical energy from an external voltage source into chemical energy that drives a reaction.

The external voltage source is usually a battery. This energy form generated from the battery helps to drive chemical reactions.

The process involves the decomposition of an ionic compound by means of current passed into the aqueous or molten form of the compound through conductors known as electrodes.

Calculate the nuclear binding energy in mega-electronvolts (MeV) per nucleon for 136 Ba . 136 Ba has a nuclear mass of 135.905 a
sergey [27]

Answer:

8.194 Mev per nucleon

Explanation:

Mass of Barium = 135.905 amu

number of proton = 56, number of neutron = 80

Md = (Mp + Mn) - Mb Mp is the mass of proton, Mn is the mass of neutron, Mb is the mass of barium and Md is the mass defect

Mn = 1.00867 amu Mp = 1.00728 amu

Md = ( 56 ( 1.00728) + 80 ( 1.00867) = 137.1013 - 135.905 =1.1963 amu

Md = 1.1963 × 1 ÷ ( 6.02214 × 10 ²⁶ amu ) = 1.9865 × 10 ⁻²⁷ kg

Energy = mc² = 1.9865 × 10 ⁻²⁷ kg × (2.99792 × 10 ⁸ m/s)²

E= 1.78537 × 10⁻¹⁰ J

to convert to Mev

1.78537 × 10⁻¹⁰ × 6241457006000 = 1114.33 Mev

binding energy per nucleon = 1114.33 / 136 =8.194 Mev per nucleon
