Answer is (1) - less mass and greater penetrating power.
Alpha particle is a ₂⁴He nucleus while beta particles are electrons. Hence, the mass of alpha particle is greater than the mass of beta particle. But, the penetrating power is higher in beta particle than alpha particle. Alpha particles can be blocked by few papers but beta particles can go through those papers.
Answer:
99.24 gm of nitrogen .
Explanation:
molecular weight of ammonia = 17 , molecular weight of nitrogen = 28.
2 NH₃(g) + 3 CuO(s) → 1N₂(g) + 3 Cu(s) + 3 H₂O(g)
2 x 17 gm 28 gm
( 34 gm )
34 gm of ammonia forms 28 gms of nitrogen
1 gm of ammonia forms 28 / 34 gms of nitrogen
120.51 gn of ammonia forms 28 x 120.51 / 34 gms of nitrogen
28 x 120.51 / 34 gms
= 99.24 gms of nitrogen will be formed .
Answer D; if you spray perfume into a corner, it will eventually diffuse, but initially it has a higher concentration than all other corners of that room.
Delta E= R[1/n^2 (initial) - 1/n^2 (final) ]
so transition n=3 to n=1 will emit more energy
Answer:
847 mL
Explanation:
Step 1: Find conversion
1 L = 1000 mL
Step 2: Use Dimensional Analysis
<em>We see that Liters and Liters cancel out, so we simply multiply.</em>
847 mL
