Can science be disproven by philosophy or religion
bagirrra123 [75]
Well, without any bias or my own opinion yes and no, I personally think they cancel each other out in the eyes of scientists some religious events seem out there, but in the eyes of religious leaders they feel that the theory of evolution and such things are a lie because of Adam and Eve. So it really depends on which side of the argument your on and what that entails

P.S. I don’t mean to upset you or anybody I’m just giving my view on the outside from the situation and this is NOT my opinion just simply stating what I see :)

Diano4ka-milaya [45]

Answer:

94.0 g.

Explanation:

Hello!

In this case, since the lay of conservation of mass states that energy cannot be neither created nor destroyed, during a chemical reaction it is seen that the reactions undergo a change by which bonds can be broken or formed depending on the case. Thus, for the formation of sodium chloride we evidence the formation of the Na-Cl bond which means sodium is combined with chlorine according to the following chemical reaction:

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

It means that the reuslting mass of product is:

m_{NaCl}=23.0+71.0g=94.0g

Best regards!

To find: Balance the equation
Solution:
Taking LHS of the equation
LHS=Na2O+H2O
There is 2 sodium, 2 oxygen,& 2 hydrogen
To balance the equation we have equal number of atom so we multply 2 to the RHS=2NaOH
There fore the equation form is
Na2O+H2O=2NaOH
