Answer:
Gravitional Force
Explanation:
Every planet has a gravitational pull which attracts all objects; the moon is no exception. It says forces in the question but I know for sure gravitational force is apart of it.
Answer:
NaCl is the correct answer
The STP stands for standard temperature and pressure which means in a condition where the temperature is 273.15K and the pressure is 0.986atm. In STP, an ideal gas will have a volume 22.4 liters for every mol of gas. Then, the amount of molecule of the <span>33.6 l of chlorine gas (Cl2) would be:
volume of gas/ number of mol= 22.4l/mol
</span>33.6l/ number of mol= 22.4l/mol
<span>number of mol= 33.6l / (22.4 liters/mol)= 1.5 moles
The mass of the gas would be: 1.5 moles * </span><span>70.906 </span>g/mol= 106.359 grams
Answer: Cations are positively charged ions.
Explanation: In cations the number of electrons is not equal to the number of positively charged protons. This is due to reason that cations donates their outer valence electrons making the atom less electronegative. The amount of electrons donated indicates the charge of the cation.
Of the sodium nitrate as molarity of a solution is expressed as the number of moles of a given substance per 1000cm3 or 1dm3 of water
