Non-metals have a larger number of outer electrons called valence electrons. Therefore, it is easier for them to "steal" valance electrons from other elements with fewer valence electrons(usually metals)
For example, Chlorine(Cl) has 7 ve-. When forming an ion it will steal one electron from a metal. and gain a charge of -1. Because the ion is NEGATIVELY charged, it will be called an anion.
Nonmetals form anions.
Vocab:
cation: Paws-itively charged ions (get it? because its a CAT ion?)
anion: negatively charged ions
<u>Answer:</u> The increase in temperature is 7.14°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 14.5 kJ = 14500 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 485 g g
c = specific heat capacity of water = 4.184 J/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the increase in temperature is 7.14°C
