Hey there!
<span>Atomic Masses :
</span>
H = <span>1.00794 a.m.u
N = </span><span>14.0067 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
HNO3 = </span>1.00794 + 14.0067 + ( 15.9994 * 3 ) => <span>63.0128 g/mol</span>
Answer:
6.3 atm
Explanation:
P2=T2P1/T1
Change C to K
We can check this by knowing that P and T at constant V have a proportional relationship; Hence, this is correct.
Answer: 208g
Explanation: Since 224 grams produces 96 grams more, then 112 grams will produce 208 grams.
Answer:
In an earthquake, the initial seismic energy wave is called a primary wave. It compresses the material ahead of it; other types of subsequent waves travel in sideways and up-and-down motions. A primary wave travels at different speeds depending on what type of substance it is traveling through. In order to determine how long it will take to travel 2,000 km we have to do the math, using the speed in km/sec and setting up proportions. In a solid such as rock, the primary wave can travel at 5 km/sec; it would take 400 seconds, or about 6.7 minutes to travel 2,000 km. If traveling through water, the wave travels at about 1.45 km/sec and would need 1,379 seconds (23 minutes) to travel 2,000 km. Primary waves traveling through air travel at the speed of sound (.34 km/sec), and would take 5,882 seconds (98 minutes) to travel 2,000 km.
