Gas pressure is measured in mmHg with a barometer
Answer:
6 atm
Explanation:
Using the formula P1V1=P2V2
P1= Initial Pressure
V1= Initial Volume
P2= Final Pressure
V2= Final Volume
And knowing that at stp gas will always be at 1 atm
250L(P2) = 1500
P2= 6 atm
Answer:
0.301 g/mL
Explanation:
Density = Mass / Volume
Step 1: Define variables
M = 84.0 g
V = 279 mL
D = ?
Step 2: Substitute and Evaluate for D
D = 84.0 g / 279 mL
D = 29/93 g/mL
D = 0.301075 g/mL
Step 3: Simplify
We are given 3 sig figs
0.301075 g/mL ≈ 0.301 g/mL
Explanation:
An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.
Symbol of an alpha particle is .
A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is .
According to the given question, the decay series chart along with reaction equation are as follows.
(a) Lead-214 changes to bismuth-214.
(b) Bismuth-214 changes to polonium-214.
(c) Polonium-214 changes to lead-210.
Therefore, we can conclude that proper order of nuclear particle emission is beta, beta, alpha.
