Answer and explanation:
A museum curator is most likely an art conservationist. They would have to determine the age an art piece was developed and ways to preserve older artefacts.
These processes would require the use of chemicals and physical tests, and also research laboratories.

Answer:
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O
Explanation:
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 1NaC₂H₃O₂
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O₂
(on the reactant side there are two molecules of C₂H₃O₂ and 2 atoms of Na, so in order to balance that we put the coefficient 2 on NAC₂H₃O₂)
So the final product is
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O₂
Heredity refers to the passing of traits from parents to their offspring (either by asexual or sexual reproduction).
Answer:
Results cannot be generalized. Looking at this table, it can be hard to see how the two types of data can be combined. Indeed, while they are fundamentally different quantitative and qualitative data share an important relationship with one another and, when integrated properly, can make each other more useful.
Explanation:
Hope this helps!
142 g ---------------- 6.02 x 10²³ molecules
0.920g g ------------ ( molecules )
molecules = 0.920 x ( 6.02 x 10²³ ) / 142
molecules = 5.53 x 10²³ / 142
= 3.89 x 10²¹ molecules
1 molecule P2O5 -------------------------- 7 atoms
3.89 x 10²¹ molecules -------------------- ( atoms )
atoms = ( 3.89 x 10²¹) x 7 / 1
atoms = <span>2.72 x 10²² atoms of P2O5
Hope this helps!!!
