Answer: When they do, they transfer some of their energy. The energy is transferred from particle to particle. It is sort of like a row of dominoes falling over. In this process, thermal energy moves through a substance. It can even move into other nearby substances. In Figure above, conduction occurs between particles of the metal in the pot. It also occurs between particles of the pot

when and if element 119 is discovered predict where it would be placed on the modern periodic table
Answer:yes
Explanation:
Because modern periodic table is designed in such a way that it can accomodate any new elemet which may be discovered in future
We have that for the Question "when and if element 119 is discovered predict where it would be placed on the modern periodic table" it can be said that With the existing information the element 119 will most likely be i the 8th period and the first group of the periodic table
8th period and the first group of the periodic tableFrom the question we are told
when and if element 119 is discovered predict where it would be placed on the modern periodic table
Generally
The Periodic table is naturally designed to accommodate new elements based on there properties
Therefore
With the existing information the element 119 will most likely be i the 8th period and the first group of the periodic table

Answer:
[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]
Reactions:
[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> KNO_{3} + PbCrO_{4}[/tex]
Explanation:
In the reaction, the CrO4(Chromate) is a compound NO3(Nitrate) is a compound as well.
Ignore the number in front of the reaction first, calculate how many K, Cr, O, Pb and N in the equation for both left and right side.
Left side: K=2, Cr=1, Pb=1, N=2, O=10
Right side: K=1, Cr=1, Pb=1, N=1, O=7
So we need 3 more oxygen, 1 more nitrogen and 1 more potassium on the right.
If we add a 2 in front of KNO3, there will be 2 potassium, 2 Nitrogen and 6 oxygen, which the reaction complete.
Conclusion:
[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]
