If 0.0469 g of mg metal reacted with hydrochloric acid completely, temperature is 21.0 c barometric pressure is 759.0 mm hg, and the product was collected by volume by water displacement; how much volume of gases would be measured in ml? show your work!
a) what is the temperature in kelvin?
b) what is partial pressure due to water vapor at 21.0 c?
c) what is partial pressure of the hydrogen gas, ph2 (in atm)? *remember dalton's law of partial pressures for a "wet" gas*
d) what is moles of hydrogen gas created in moles?
e) what is the ideal gas law constant, r (in atm-l/mole- k) ?
f) what is the working equation for volume ( using pv= nrt)
g) what is the volume of gases in ml?

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.
