1.the element silicon would be expected to covalent bond(s) in order to obey the octet rule.
use the octet rule to predict the formula of the compound that would form between silicon and hydrogen , if the molecule contains only one silicon atom and only single bonds are formed.
formula:

2. the element germanium would be expected to covalent bond(s) in order to obey the octet rule. use the octet rule to predict the formula of the compound that would form between germanium and chlorine , if the molecule contains only one germanium atom and only single bonds are formed.

formula:

How would you reduce the volume of gas

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
