You are trying to burn 5 kg of wood. You have the wood heated at 200°C and you increase the heat to 300°C at which the wood catches fire. Your instruments show a change in thermal energy to 880,000 J. What is the specific heat of wood? PLEASE HELP I NEED IT RIGHT NOW! PLEASE I BEG YOU I REALLY NEED IT NOW

chemistry sucks a**

explanation:

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.
