For each of the following experiments (1-4), calculate the ph at each titrant volume listed below (i-vii). when you are finished with this problem, you should have 28 ph values calculated. titrant volume: 0.0 ml 12.5 ml iii. 25 ml iv. 37.5 ml v. 50.0 ml vi. 75.0 ml vii. 100.0 ml experiment 1: 50.0 ml of 0.100 m hno3 titrated with 0.100 m naoh experiment 2: 50.0 ml of 0.100 m ch3cooh titrated with 0.100 m naoh experiment 3: 50 ml of 0.100 m naoh titrated with 0.100 hci experiment 4: 50 ml of 0.100 m nh3 titrated with 0.100 hci

Sylvanite is a mineral that contains 28.0% gold by mass. how much sylvanite would you need to dig up to obtain 77.0 g of gold? explain how you got your answer and the steps you took. you

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
