A sample of hydrogen gas collected by displacement of water occupied 30mL at 24 C on a day when the barometric pressure was 736t
shusha [124]

Answer:

v_2=6,48*10^{-4}L

Explanation:

From the question we are told that:

Volume of hydrogen  V_1=30mL=>30*10^{-3}

Temperature T_1=24C=>24+273=>297k

Pressure of water P_1=22.4torr=>\frac{22.4}{760}=0.0295atm

Let

STP(Standard Temperature and pressure)

 T_2=273K

 P_2=1atm

Generally the equation for ideal gas is mathematically given by

 \frac{p_1V_1}{T_1}=\frac{P_2V_2}{T_2}

Therefore

 v_2=\frac{P_1v_1T_2}{T_1P_2}

 v_2=\frac{0.0295*30*10^{-3}*273}{297*1}

 v_2=6.48*10^{-4}L (at STP(Standard Temperature and pressure))

2.2.<br> Name the two stages of photosynthesis
andre [41]

Answer:

1. Light-dependent stage

2. Light-independent stage or Calvin cycle

Explanation:

Photosynthesis is the process by which plants and other autotrophic organisms synthesize their food (glucose) in the presence of sunlight as energy source. However, this photosynthetic process, which is a metabolic reaction occurs in two stages namely; Light-dependent stage and Light-independent stage.

- The light dependent stage occurs in the thylakoid membrane of the chloroplast. It involves the synthesis of NADPH and ATP needed for the light independent stage of photosynthesis.

- The light independent stage also known as Calvin cycle occurs in the stroma of the chloroplast. This is the stage where glucose is synthesized using inorganic source of carbon (CO2).
