Answer:
AgNO3 precipitation test
pH test
Flame test
Explanation:
Starting with AgNO3 will help you clearly identify HCl, K2C2O4, Na2CO3 via double decomposition reaction. The colour of the precipitate will tell which solution has been identified. For instance, a white precipitate shows that the AgCl was formed from HCl.
pH test can identify HCl and Na2CO3 while flame test can only identify sodium carbonate and barium nitrate.
First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,
theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
theoretical amount of Na2O = 72.9 g of Na2O
Calculation of percent yield,
% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%
Answer: 84.75%
Answer:
the changing tempure in rocks causing it to back apart
As a noble gas, neon tends to forms no bonds of any kind- so it would be fewest with zero.
Answer:
Heterogenous
Explanation:
Heterozygous mixtures seperate and consist of two or more layers. For example, When oil and water are combined, they do not mix evenly, but instead form two separate layers. They also use filter and can scatter light.
