MgBr2(aq) is an ionic compound which will have the releasing of 2 Br⁻ ions ions in water for every molecule of MgBr2 that dissolves.
MgBr2(s) --> Mg+(aq) + 2 Br⁻(aq)
[Br⁻] = 0.065 mol MgBr2/1L × 2 mol Br⁻ / 1 mol MgBr2 = 0.13 M
The answer to this question is [Br⁻] = 0.13 M
Answer : The 
must be administered.
Solution :
As we are given that a vial containing radioactive selenium-75 has an activity of 
.
As, 3.0 mCi radioactive selenium-75 present in 1 ml
So, 2.6 mCi radioactive selenium-75 present in 
Conversion :
Therefore, the must be administered.
Answer:
The answer is
<h2>4.54 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of rock = 454 g
volume = 100 cm³
The density of the rock is
We have the final answer as
<h3>4.54 g/cm³</h3>

Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are
important resources for a country’s energy mix, only nuclear power is
capable of producing large amounts of electricity 24 hours a day, 365
days a year.
For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC),
the U.S. Environmental Protection Agency and the U.S. departments of
Energy and Transportation—establish radiation protection regulations for
U.S. nuclear plants based on internationally recognized scientific
studies.
For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas:
reactor safety, radiation safety and security.
