Answer:
Contact with corrosive substances requires flushing with water and removing contaminated clothes and jewelry. With a fire, people should first evacuate the lab. Once safe, they should close doors, pull the fire alarm, and call emergency services. Anyone who is on fire should stop, drop, and roll.
Explanation:
Because that is what you are supposed to do
Answer:
How many electrons are there in the lithium ion?
The battery goes on and on and on.
Each element have an electron configuration in depending of the principle (Hund’s rule , etc).
So by their atomic number tend to indicate the number of protons that are equal in a number of electrons.
So the atomic number indicate the numbers of electrons.
Atoms have direct stability as such lithium tend to be located in group 1A and period 2.
Lithium have the atomic number of 3.
So naturally their protons/number of electrons are 3.
The electron configuration is (LI) 1s² 2s¹ or [He] 2s¹.
To archive stability as any noble gas element HE , Then the lithium will form an electron to form a Lithium ion which is Cation LI+.
So by it the lithium ion had 2 electrons.
Can you provide a picture of the dropping liquid, please?
1) All the CO2 comes from the C24 H30 N3 O
2) To balance C from CO2 with C from C24, the ratio of cC24 H30 N3 O to CO2 is 24 / 1
3) Convert 1.20 g of CO2 to number of moles
number of moles = mass in grams / molar mass
mass = 1.20 g
molar mass = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol
number of moles = 1.2 g / 44.01 g/mol = 0.0273 mol
4) proportion
1 mol C24 H30 N3 O / 24 mol CO2 = x / 0.0273 mol CO2
=> x = 0.0273 mol CO2 * 1 mol C24H30N3O / 24 mol CO2 = 0.00114 mol C24H30N3O
5) Convert 0.00114 mol C24H30N3O to grams
molar mass = 376.5 g/mol
mass = 0.00114 mol * 376.5 g/mol = 0.429 g
6) mass percent in the mixture
mass percent = (mass of lsd / mass of mixture) * 100 = (0.429g / 1.0g) * 100 = 42.9%
Answer: 42.9%
