NAME: 1. Write the balanced equation for reaction of a Group 1A metal (M) with HCl. 2. Write the balanced equation for reaction of a Group 2A metal (M) with HCI. 3. A trial of this experiment produced the following data TABLE 1: DATA Metal Sample Mass Volume of Gas Produced 75.89 mL Vapor Pressure of Water at this T 16.5 torr Barometric Pressure 0.0425gTemperature of the Gas 19.1 oC 758.3 torr Use the data given in Table 1 above to calculate the answers to fill in the following table: (a) Pressure of H2 gas (b) Moles of H2 produced torr atm Moles of Group 1A metal required to produce the moles of H2 calculated in (b) dl Calculated Atomic Mass of Group 1A element el Moles of Group 2A metal required to produce the moles of H2 calculated in (b) Calculated Atomic Mass of Group 2A element What metal was used in this experiment? Which group is the metal used in this n experiment from (1A or 2A)?Explanation / Answer
1)M + HCl--->MCl + H+( here the valency is 1 and hence only one chlorine is taken up)
2)M +2HCl---->MCl2 + 2H+( valency is 2 and hence two chlorines taken up)
