Answer:
300 kPa
Explanation:
P2=P1V1/V2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
Answer:
Cs and I
Explanation:
Salts are formed when an ionic bond is formed between two elements in the compound. Let us recall that the kind of bond formed between any two elements depends on the magnitude of electronegativity difference between the two elements.
Among the options listed, the highest degree of electronegativity difference occurs for the bond between Cs and I. This implies that this bond is ionic and the combination of the two elements will lead to salt formation.
Answer:
A) Crystal lattice
Let (NO2)n be the molecular formula,
(14+16x2)n=138.02
n=3
molecular formula: (NO2)3=N3O6
V is more reactive, hope this helps!
