Answer:
816L adicionales para mantener la concentración
Explanation:
<em>Cuánta agua debe adicionar el cuidador para que se mantenga la concentración del desinfectante?</em>
<em />
El desinfectante, NaClO, idealmente debe estar en una concentración de:
35.8g / 1000L = 0.0358g/L
Como el velador agregó 65g de desinfectante, la cantidad de agua necesaria es:
65g * (1L / 0.0358g) = 1816L de agua son necesarios
Asumiendo que el velador agregó 1000L, el cuidador debe agregar:
1816L - 1000L =
<h3>816L adicionales para mantener la concentración</h3>
Answer:
a) 3H2 + N2 = 2NH3
b) 2K + 2H2O = 2KOH + H2
c) 2Al + Fe2O3 = Al2O3 + 2Fe
d) Same as c)
e) Ba(OH)2 + 2HBr = BaBr2 + 2H2O
f) CaCO3 = CaO + CO2
Correct answer: C) dispersion forces
Dispersion forces are the intermolecular forces of attraction present in all types of molecules. These are the weakest forces of attraction in which atoms of the molecule align in such a way that weak forces of attraction develop between electron cloud of one atom and the positively charged nucleus of the adjacent atom. This is referred to as induced dipole-induced dipole type of interaction. Therefore in dispersion forces temporary dipoles are developed due to constant motion of electrons that results in asymmetric electron distribution around the nucleus in an atom.
The correct answer is C. Magnetic domains must come in pairs one north one south. I took the test.
