How do ethics affect scientific research

Ethics affect scientific research because it involves doing experimentation and analysis of data without bias no matter what the conclusions point to.

Explanation:

Ethics is referred to rules provided by an external source . Moral(s) is referred to due to an own individuals own principles regarding if it is wrong or right. Ethics is when we think it is the right thing to do. Morals is when we believe it is wrong or right.

Hope this helps :)

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

i think that is the right
