Answer:
they are producers and they have means to keep themselves warm
Explanation:
I took test and saw answer.
The activity series goes top to bottom, most active to least active elements, going: Li, K, Ba, Sr, Ca, Na, Mg, Mn, Zn, Fe, Cd, Co, Ni, Sn, Pb, H, Cu, Ag, Hg, Au.
Thus, your list of metals would go from most reactive to least reactive: Li, K, Mg, Zn, Fe, Cu, Au
Answer:
Dissolving ice tea mix in water is a chemical change
Explanation:
It is a chemical change because you can not bring back the ice tea mix back if you mix it in water.
Hope it helps
The given question is incomplete. The complete question is given here :
The equilibrium constant for the reaction is 
M.
This value indicates that
A. 
is a stronger base than 
B. HCN is a stronger acid than HONO
C. The conjugate base of HONO is
D. The conjugate acid of CN- is HCN
Answer: A. is a stronger base than
Explanation:
Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.
When 
; the reaction is product favoured.
When 
; the reaction is reactant favored.
; the reaction is in equilibrium.
As, 
, the reaction will be product favoured and as it is a acid base reaction where 
acts as acid by donating 
ions and acts as base by accepting
Thus is a strong acid thus will be a weak conjugate base and is a strong base which has weak 
conjugate acid.
Thus the high value of K indicates that is a stronger base than
Answer:
It will have 5 valence electrons as its in group 5.
The atom will gain as its closer to the full configuration 8.
The charge will be 3- as it will gain 3 electrons.
