What is the molecular geometry for H2O?

Which of the following shows the molecular equation for sodiumcarbonate with hydrochloric acid reaction? A)  Na2CO3  +  2HCl  →  2NaCl  +  H2O  +  CO3 B)  NaHCO3  +  HCl  →  NaCl  +  H2CO3 C)  NaHCO3  +  HCl  →  2NaCl  +  H2CO3 D)  Na2CO3  +  2HCl  →  2NaCl  +  H2O  +  CO2

A calorimeter is to be calibrated:  51.203 g of water at 55.2 Celsius is added  to a calorimeter containing 49.783 g of water at 23.5 Celsius. After stirring and waiting for the system to equilibrate, the final temperature reached 37.6 Celsius. Calculate the calorimeter constant.  Heat =mass X specific heat X change in temperature
