D. NaOH + HCI NaCl + H,0
Explanation:
The last option is a double displacement/replacement reaction.
This reaction is a neutralization reaction in which an acid combines with a base to produce salt and water only.
NaOH + HCl → NaCl + H₂O
- A double displacement reaction is one that occurs between ionic compounds.
- In this reaction, there is an actual exchange of reaction partners.
One of the following conditions serves as a driving force;
- Formation of water or any other non-ionizing compound
- Liberation of gases
- Formation of a precipitate

Newtons first law of motion
object in motion stays in motion, object at rest stays at rest unless acted upon an unbalanced force
Like poles repel and unlike poles attract. Magnetic poles always occur in pairs of north and south—it is not possible to isolate north and south poles.
Explanation:
The De-Broglie wavelength in terms of potential difference is given by:
Where,
h is Planck's constant
m is mass of charged particle
V is potential difference
e is the amount of charge
It means that the De-Broglie wavelength is inversely proportional to the mass.
Since, the mass of the proton is more than the mass of the electron. So, the De- Broglie wavelength of the electron is larger than proton.
Basically, Newton's ideas matched up better with experiments and observations about the natural world than Aristotle's did. Newton gave a rigorous mathematical framework that made very specific predictions about our world, while Aristotle in general made more comparative laws, that even when true were less useful than the certainty Newton's laws gave us. Many of Newton's laws have been found to be at least partially incorrect now, for instance his laws of motion fall apart at speed nearing the speed of light, his laws of gravity fall apart when talking about more than two objects and in the presence of large gravitational fields that are close together, and Newton's law of cooling is just untrue in general (though can make some approximations in narrow temperature ranges).
