1. identify the products formed when 1 mL of Dil. Hydrochloric acid is added to 1 g of sodium metal?
2. two unequal resistance are connected in parallel. if you're not provided any other parameters (eg. numerical values of I&R), what can be said about the voltage drop across the two resistors?
3. some work is done to move to charge Q from infinity to a point A in space. the potential of the point A is given as V. What is the work done tomove this charge from infinity to terms of Q & V?
4. Explain how ozone being a deadly poison can still perform an essential function for our environment.
5. which of the following isn't observed in a homologous series? give reason for your choice.
answer is change in chemical properties.

Answer:
1. 2HCl (aq) + 2Na (s) = 2NaCl + H2
2. in attachement....
3. Electric potential (V) at a point is defined as the work done (U) required to bring a charge (q) from infinity to that point divided by the charge: V = U/q. With this definition, V = 0 at infinity. Electric potential is scalar
4.Ozone layer is deadly poisonous because it is combination of 3 oxygen atoms which make it highly reactive which is not good for our body system and it is essential because it shields the surface of the earth from the entry of UV rays from the sun which can harm us by causing skin burnings and skin cancer.
5. Change in chemical properties It does not occur due to the presence of the same functional group.
