3. What do platelets do? 10 points
O a. help build the number of white blood cells
O b. help build the number of red blood cells
O c. help stop bleeding
O d. gives blood its color

C help stop bleeding

Explanation:

Platelets stop bleeding by clumping and forming plugs in blood vessel injuries

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
