The radiation emitted is a beta particle with a -1 charge. Beta particles have a <span>medium penetrating power. An emission of beta particles requires shielding because of the hazards it pose to humans. Thus, one characteristic of this radiation is that <span>some shielding is required.</span></span>
Answer:
fossil fuels are non-renewable resources .
Answer: Relative humidity
Explanation:
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
Answer:
d. 117 grams
Explanation:
The mass of the table salt produced will be 117 grams.
Chemical reactions obey the law of conservation of mass. In this regard, matter is neither created nor destroyed in the course of a chemical reaction. It is expected that the mass of the reactants and products remain the same.
The reaction expression:
2Na + Cl₂ → 2NaCl
So, mass of sodium = 46g
mass of chlorine formed = 71g
Mass of NaCl = 46 + 71 = 117g
