HELPP Based on the nature of the reactants, which reaction below will occur at the fastest rate at 84°C ?
1. 2KCIO,() 2KCI(s) + 30,(g)
3. N.(g) + 3H2(g) → 2NH,(g)
7. H(aq) + C, H,O, (aq) » HC, H,O,
8. C(s) + O2(g) → CO
(G)

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

the answer is c i took the test

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on
