A positive nitrite test suggests the presence of a minimum of 105 microorganisms / mL in your urine. The nitrite test in urine is a method used to detect the presence of microorganisms in the urine. This is a diagnostic test for urinary tract infections. Microorganisms that are the cause of UTI or urinary tract infection produce an enzyme that would change nitrates in urine into nitrite. This nitrite that is formed is the ion that is monitored and measure in a nitrite test. If nitrites are present in the urine, then most probably UTI is present. A positive in this test is called nitrituria.

Ill give brainliest if you answer right

Paraphin [41]

Answer:

It'll be the same as 58.44 amu. This is because of the law of conservation of mass which states that total mass of reactants is always equal to the total mass of products formed.

pls give brainliest for the answer

Consider a cobalt-silver voltaic cell that is constructed such that one half-cell consists of the cobalt, Co, electrode immersed

umka21 [38]

Answer:

Anode half reaction;

Co(s) ----> Co^2+(aq) + 2e

Cathode half reaction;

2Ag^+(aq) + 2e-------> 2Ag(s)

Explanation:

A voltaic cell is an electrochemical cell that spontaneously produces electrical energy from chemical reactions. A voltaic cell comprises of an anode (where oxidation occurs) and a cathode (where reduction occurs). The both electrodes are connected with a wire . A salt bridge ensures charge neutrality in the anode and cathode compartments. Electrons flow from anode to cathode.

For the cell referred to in the question;

Anode half reaction;

Co(s) ----> Co^2+(aq) + 2e

Cathode half reaction;

2Ag^+(aq) + 2e-------> 2Ag(s)
