Answer:
The answer to your question is: density = 5 g/cm³
Explanation:
Data
Volume = v = 2 m³
mass = m = 1 x 10⁴ kg
Density = d = ? g/cm³
Formula
density = mass/volume
Volume
1 m³ ------------------- 1 000 000 cm³
2 m³ ------------------ x
x = (2 x 1 000 000) / 1
x = 2 000 000 cm³
Mass
1 kg ------------------ 1000 g
1 x 10⁴ kg ------------ x
x = (1 x 10⁴ x 1000) / 1
x = 10 000 000 g
density = (10 000 000) / 2 000 000
density = 5 g/cm³
The molecule is symmetric, a tetrahedron. Thus, the 4 polar bonds cancel each other out. (It is easier to see with a one dimensional molecule like CO2, which is linear with the C in the middle. The 2 polar bonds cancel each other.
Answer is: b. safe disposal of hlrw.
HLRW is High-level radioactive waste.
Nuclear (radioactive) waste is hazardous to all forms of life and the environment.
Long term storage of radioactive waste is needed. It is important the stabilization of the waste into a form which will neither react nor degrade over many years.
If nuclear waste is wasted in atmosphere or into oceans and lagre lakes, eventually it will come in contact with living organisms.
Nuclear fission is a nuclear reaction or a radioactive decay where nucleus of atom split into smaller ligher nuclei.
CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O
D. All of the Above (A, B, C)
