<u>Answer:</u> The atomic radius of iron is 128 pm.
<u>Explanation:</u>
To calculate the radius of the metal having FCC crystal lattice, the relationship between edge length and radius follows:
Where,
a = edge length = 362 pm
r = atomic radius of iron = ?
Plugging values in above equation, we get:
Hence, the atomic radius of iron is 128 pm.
Answer:
A) 122 atm
Explanation:
PV = nRT
Solve for P --> P = nRT/V
n = 10.0 mol + 5.0 mol = 15.0 mol
R = 0.08206 L atm / mol K
T = 25 + 273 = 298 K
V = 3.0
P = (15.0)(0.08206)(298) / (3.0) = 122 atm
Answer:
(4) The navy needed a faster way to move ships between the Atlantic and Pacific Oceans.
Explanation:
The Panama Canal was an artificial eighty-two (82) kilometers water-way that connects the Atlantic Ocean with the Pacific Ocean in Panama and it enhanced maritime trades.
The construction of the Panama Canal became more important to the United States after the Spanish-American War because the navy needed a faster way to move ships
between the Atlantic and Pacific Oceans.
Answer:
10 neutron
Explanation:
No.of neutron=Mass no. -- atm no.(or no.of p)
No of neutron=19 -- 9
=10
Water is an incomplete combustion as water is still produced by carbon monoxide and carbon are produced instead of carbon dioxide.
