Answer:
Visible light waves
Explanation:
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.
Answer:
12 more oxygen
Explanation:
An atom is the smallest particles that can take part in a chemical reaction
The given compounds are:
3Mg₃(PO₄)₂
Number of oxygen atoms = 3[2 x 4] = 24 oxygen atoms
For;
4Al₂O₃;
Number of oxygen atoms = 4 x 3 = 12 oxygen atoms
In 3Mg₃(PO₄)₂ , there are 24 - 12 = 12 more oxygen atoms than in 4Al₂O₃;
Answer:
True
Explanation:
An orbital is is the space occupied by a pair of electrons. The maximum number of electrons in an orbital is 2.
The maximum number of electrons in in the orbitals are two.
For s-sublevel with one orbital we have two electrons
p-sublevel with three orbitals we have six electrons
d - sublevel with five orbitals we have ten electrons
f - sublevel with seven orbitals we have fourteen electrons
Each orbital can take a maximum of two electrons.
An acid is deemed strong if it can readily or easy "donate" a proton (H+) to the other ions in the solutions. Also, to donate or lose the proton or H+, the acid must dissociate (split into ions) in the solution. The more it can readily dissociate, the stronger the acid is.
