Virtually all acids release hydrogen ions (or protons) in the water
Answer:
Sulfur
Explanation:
A non-metal in the third period that should have chemical properties similar to oxygen is sulfur.
This is because elements in the same group/family have similar chemical properties.
- Chemical properties is predicated on the number of valence electrons within an atom.
- The number of valence electrons is the number of outermost shell electrons within an atom.
- Elements combines with one another using these valence shell electrons.
- Since sulfur is in the third period and the same vertical group as oxygen, they have similar chemical properties.
Wavelength decreases as frequency increases.
Imagine a heart rate graph. As the heart beats faster, frequency increases and the time between heartbeats decreases (wavelength).

Answer:
Option E
Deuterium has one more neutron than hydrogen
Explanation:
Deuterium is an isotope of Hydrogen and hence there will variation in the number of neutron
Hydrogen has 0 neutron
Deuterium has 1 neutron and
Tritium has 2 neutron
Thus option E is correct
Answer:
17. The iron metal is oxidized to form the iron oxide known as rust.
19.A saturated solution will not dissolve any more solute and any extra solute added will simply stay as it is, without dissolving. An unsaturated solution has less solute than its solubility and hence can still add more solute, till it reaches the saturation level.

32. The periodic table was first assembled in 1869 by a Russian chemist named Dmitri Mendeleev. He came up with a way of organizing the elements that were known at the time, arranged them in order of atomic weight, and then grouped them into rows and columns based on their chemical and physical properties. Here is a unique "Mayan" format Periodic Table. Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells.
