Calculate the total heat (joules) of formation for 30 grams of water that is heated from 32C to 48C

2008.3 J

Explanation:

Use the equation q=mcΔT where

q = heat

m = mass

c = specific heat capacity (for water this is 4.184 and is a given)

delta T = change in temperature in C (final - initial)

q = 30 g x 4.184 J/g*C x (48-32)

q = 2008.3 J (or 2 kJ)

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.
