Answer:
this is good update to the doctor and I will be taking the test soon and will have a gf with my
Explanation:
The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.
a) They are solid at ambient temperatures of 25 ° C and pressure of 1 atm.
b) Ionic compounds represent high temperature melting and boiling.
c) They are hard and brittle and then subjected to the impact, break easily, creating planar faces.
d) When dissolved in water, or pure liquid, carry electrical current due to the existence of ions that move freely and can be attracted by the electrodes, closing the electric circuit.

Mass of SO2 = mass of sulfur+ mass of oxygen
⇒ 64 g= mass of sulfur+ 32 g
⇒ mass of sulfur= 64 g-32 g
⇒ mass of sulfur= 32 g.
There is 32 g of sulfur in 64 g of SO2~
Answer: operating machines they are easy to handle
