I had this same question a while back, so I may not be right, but I'm pretty sure it's D. None of the above.
Answer:
A. 650 g
Explanation:
The equation of the reaction is given as;
2 HgO(s) --> 2Hg(s) + O2(l)
From the reaction;
2 mol of HgO produces 1 mol of O2
x mol of HgO would produce 1.50 mol of O2
2 = 1
x = 1.5
Solving for x;
x = 1.5 * 2 / 1 = 3 mol
Converting to mass;
Mass = Number of moles * Molar mass
Mass = 3 mol * 216.59 g/mol
Mass = 649.77 g ≈ 650. g
Correct option is ;
A. 650 g
Answer:
2 8 5
Is phosphorus normal ground state configuration this configuration 2 7 5 is not possible for phosphorus or potassium
Explanation:
Explanation:
(a) Formula for critical stress is as follows.
Here, = 54.8
= 0.99
a = 0.8 mm = m
Putting the given values into the above formula as follows.
=
= 1107 MPa
Hence, value of critical stress is 1107 MPa.
(b) Applied stress value is given as 1205 MPa and since it is more than the critical stress (1107 MPa) as a result, a fracture will occur.
