Write the formula unit equation for this reac- tion occurring in water: ammonium fluoride and magnesium chloride are mixed to form magnesium fluoride and ammonium chloride.
1. 2 nh4f (s) + mgcl2 (aq) → mgf2 (aq) + 2 nh4cl (s)
2. 2 nh4f (aq) + mgcl2 (aq) → mgf2 (s) + 2 nh4cl (aq)
3. 2 nh4f (aq) + mgcl2 (aq) → mgf2 (aq) + 2 nh4cl (aq)
4. nh4f (aq) + mgcl (aq) → mgf (s) + nh4cl (aq)
5. 2 nh3f (aq) + mgcl2 (aq) → mgf2 (s) + 2 nh3cl (aq)
6. 2 nh4f (aq) + mgcl2 (s) → mgf2 (s) + 2 nh4cl (aq)

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced

What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume? explain your answer.

Northern was a learned a fairly cold climate caused by see one from the atlantic ocean, but se was real and tends to be much warmer, sonia look good causes difference. a.cool wins cannot blow across a leg into the south mountains, b.prevent cold air from blowing over into south sea,c.the south is at much higher elevation, so it is closer to the sun, d.suppose early and has a sperience a drastic climate change in the past few years.
