I think the minimum uncertainty in the electron's velocity if the location of a particular electron can be measured only to a precision of 0.058nm is d which is 2.2X10 5 m/s. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Answer:
6750 J
Explanation:
The specific heat capacity of iron is 450 J/kg/K
Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.
Therefore;
m = 3 kg, c = 450 J/kg/K and θ = 5°C
Quantity of heat = 3 × 450 × 5
<u>= 6150 Joules</u>
Answer:
The mass of zinc sulfide produced is 
Explanation:
From the question we are told that
The mass of zinc is 
The mass of sulfur is 
The molar mass of 
is a constant with value 65.39 g /mol
The molar mass of 
is a constant with value 32.01 g/mol
The molar mass of 
is a constant with value 97.46 g/mol
The reaction is
So from the reaction
1 mole of react with 1 mole of to produce 1 mole of
This implies that
65.39 g /mol of react with 32.01 g/mol of to produce 97.46 g/mol of
From the values given we can deduce that the limiting reactant is sulfur cause of the smaller mass
So
0.250 g of react with 0.250 of to produce 
of
So
Thus the mass of the mass of zinc sulfide produced is
