There a three main types of plants, cones, flowers, and berries
Answer:
(a) Barium is produced at the negative electrode
(b) Iodine is produced at the positive electrode
Explanation:
When an electric current is passed through a solution containing electrolyte, a non spontaneous reaction is stimulated. This results in the flow of <u>positively charged ions to negatively charged electrodes(</u><u>cathode</u><u>) and negatively charged ions to positively charged electrodes(</u><u>anode</u><u>)</u>
When an electric current is passed through molten
in the electrolytic cell, the following reactions takes place:
→
+ 2
At the anode;
Iodine ions will lose an electron and will be oxidized to iodine
→
+ 
At the cathode;
Barium ions gains electrons and its reduced to barium metal
+
→ Ba
Pyrite because it doesn’t sink it floats
Answer: 28.3 g/mol
Explanation:
According to the ideal gas equation:'
P= Pressure of the gas = 0.951 atm
V= Volume of the gas = 280 mL = 0.28 L (1L=1000 ml)
T= Temperature of the gas = 25°C=(25+273)K=298 K (0°C = 273 K)
R= Value of gas constant = 0.0821 Latm/K mol
To calculate the moles, we use the equation:
Thus the molar mass of the gas is 28.3 g/mol.
