Unit 6 Flashcards
when calculating temperature what do you need to remember
To minus the temperature found to the one given in question
what is the equation for finding temperature
◇T = Q / c x m
define specific heat capacity
heat needed to increase temp of 1g of substance by 1 degrees
define heat capacity
heat needed to increase temp of an object by 1 degrees
what is an endothermic reaction
the reaction absorbs heat (positive)
what is an exothermic reaction
reaction gives off heat (negative)
which way does heat move
from high temp to low temp
when given KJ what must you do
translate into J by x 1000
what must you do when the question is given to you In grams
change from grams to moles to kj
what is the equation for molar enthalpy
(G given / 1) * (1 mol given/ atomic mass) * (KJ/ amount of mol given)
what are used in an ICE table gas (aq) solid
only gas and aq
