Answer:
A campfire is a perfect example of the different kinds of heat transfer. If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
Explanation:
Hey there!:
Mole ratio :
2 C₂H₆ + 7 O₂ → 4 CO₂ + 6 H₂O
2 moles C₂H₆ -------------------- 7 moles O₂
3.0 moles C₂H₆ ------------------ moles O₂ ??
moles O₂ = 3.0 x 7 / 2
moles O₂ = 21 / 2
moles O₂ = 10.5 moles of O₂
Hope this helps!
Carbon dioxide and Water are the products of cellular respiration.
The net ionic equation formed is
Ag^+(aq)+Cl^−(aq)→AgCl(s)
Chromium(III) nitrate and silver(I) chloride are the products of the balanced molecular equation for the reaction between chromium(III) chloride and silver(I) nitrate. An (s) next to the chemical formula for silver(I) chloride designates it as an insoluble salt.
CrCl3(aq)+3AgNO3(aq)→Cr(NO3)3(aq)+3AgCl(s)
Silver and the chloride ions are the two ions that must interact to create silver(I) chloride. By designating ions as the reactants and silver(I) chloride as the product, the net ionic equation is formed.
Ag^+(aq)+Cl^−(aq)→AgCl(s)
Ionic Equation:
In general, anions and cations react to generate a compound in a dissolved media, which is known as an ionic reaction. Water-insoluble salts are created when the ions of water-soluble salts interact with one another in an aqueous media.

I believe the correct answer would be E. When aqueous solutions of NiBr 2 and AgNO3 are mixed, a precipitate forms. As these two solutions are being mixed a reaction would happen resulting to two new compounds which are nickel nitrate and silver bromide. The reaction would be:
NiBr2 + AgNO3 = NiNO3 + AgBr2
The precipitate that would be formed would be the silver bromide since most of the silver compound are not or has low solubility in water while most of the nitrate compounds are very soluble in water. Most likely, it would be the silver bromide that is the precipitate.
