N=3^K-1 I really don't know how to explain it but that's the formula <span />
Answer:
Explanation:
If by speed ,you mean the rate at which they collide with each other then yes the answer would be
By decreasing the temperature
Since we already know thattemperature is the average kinetic energy of the molecules and increasing temperature will increase the motion of the solvent molecules and an decrease in temperature will decrease in the motion of solvent molecules
Answer:
rest will do later mom is calling me plz understand promise will do it
Explanation:
- Elements and compounds are similar in that they are both made of atoms and in some cases molecules.
- Methods of Breaking Down Compounds
- The only way to break down a compound is through a chemical change. Sometimes, energy is needed for a chemical change to happen. Two ways to add energy to break down a compound are to apply heat and to apply an electric current.
Halogens have seven valence electrons and reqires one more electron to complete its octet
Answer:
Assuming the reaction you are referring to is the following:
AgNO3 + Cu --> Cu(NO3)2 + Ag
First, we should balance the reaction:
2 AgNO3 + Cu --> Cu(NO3)2 + 2 Ag
Now we carry out dimensional analysis, taking into account the molar ratios of different species as given in the balanced reaction and molar masses (which we can look up in the periodic table).
We begin with what we know, which is that we have 16.0 g Cu reacting and work our way toward the quantity that we would like to calculate, namely moles of Ag.
16.0 g Cu x 1 mol Cu x 2 mol Ag = 0.504 mol Ag
63.5 g Cu 1 mol Cu
