Typical protein contains 16.2wt%nitrogen. A 0.500 ml aliquot of protein solution was digested, and the liberated NH3 was distilled into 10.00 ml of 0.0214 M HCI. The unreacted HCI required 3.26 ml of 0.0198 M NAOH for complete titration. Find the protein (mg protein /ml) in the original sample.

Flourine is found to undergo 10% radioactivity decay in 366 minutes determine its halflife

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

Select the correct answer from each drop-down menu.describe what happens to a carbon-11 atom when it undergoes positron emission.the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
