Answer:
Explanation:
An anion is a negatively charged atom ie. Atoms that have gained an electron.
Flouirne is a group 7 element and it is highly electronegative. It easily draws electron to itself. With an electron, the outermost shell of Flouirne would mimic that of a noble gas.
Therefore, a combination of Sr and F would make F an electron acceptor and then an anion.
Answer:
D
Explanation:
Mars is the planet between Earth and Jupiter, or the 4th planet from the Sun.
From gas equations
PV/T = Constant
Then
P1V1/T1 = P2V2/T2, but V1 = V2
Therefore,
P1/T1 = P2/T2
P2 = (P1T2)/T1
P1 = 40 psi
T1 = 60°F = 288.706 K
T2 = 90°F = 305.372 K
Substituting;
P2 = (40*305.372)/288.706 = 42.31 psi
Then, gauge pressure would read 42.31 psi.
