Below are the choices that can be found from other sources:
<span>A) elements
B) ions
C) molecules
D) neutrons
the answer is ions.
</span>A Star<span> and hence our Sun, is an almost entirely ionized ball of </span>plasma<span>, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the </span>plasma<span> produces strong magnetic fields and corresponding electric currents.</span>
Order of increasing atomic mass!
hope this helps :)
Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.
Answer:
1. Magnesium(Mg)
2.Calcium(Ca)
3.Nitrogen(N)
4.Carbon(C)
5.Mercury(Hg)
6.Gallium(Ga)
Explanation:
1.Neutral means same no. of protons and electrons which is atomic number.So element with Atomic number 12 is Magnesium.
2. No. of protons = Atomic number.So element with Atomic number 20 is Calcium.
3.Neutral means same no. of protons and electrons which is atomic number.So element with Atomic number 7 is Nitrogen.
4.C-14 isotope has two extra neutrons making it 6+2= 8 neutrons.
5.Mercury(Hg) is the name of element.
6.Gallium(Ga) and Aluminium together belongs to Aluminium family.
