write about your favorite parts of science from what you have learned so far and also be specific in ur typing it should be at least 1 page

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

the answer is 303.15 or 303

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
