You would also need to know the mol of sodium. After knowing the mol, write down the reaction;
Na + H20 -> NaOH + H2
Use the mol ratio, to find the amount of mol of sodium hydroxide. (Remember to balance the equation first)
After you have the necessary variables, use the following formula:
mass of sodium hydroxide = mol of sodium hydroxide x molar mass (relative/formula mass of sodium hydroxide)
That is how you will find the mass of sodium hydroxide.
Marie curie worked as a governess and she was awarded noble prize for her discoveries.
Explanation:
When Marie curie worked as a governess for three years her employer allowed her to teach reading to the children of peasant workers at his beet sugar factory. This was banned under Russian rule. During that time she studied chemistry lessons from her father by mail.
Marie curie was awarded the Noble prize in chemistry for her discoveries and studies of elements radium and polonium. She is the only women who is awarded the Noble prize twice.
She made her first research into the treatment of tumors with radiation and founded a Curie institutes, that are important medical research centers.
B). light energy is not required to proceed
Explanation:
In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.
- During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
- During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
- The cycle is also known as dark reactions.
- It is at this stage that carbon dioxide combines with water to form glucose.
- The reaction is initiated with light energy which produces NADPH and ATP.
- The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.
