How many liters of Hydrogen gas (H2) are collected if 52.1g of nitric acid (HNO3) are consumed at STP in the following reaction: Cu + 2HNO3 ---> Cu(NO3)2. + H2

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the volume increases

a) the particles of the chair are strongly held together.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
