The lab question is “based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? ” fill in the box to answer this question with a hypothesis. hypothesis: if a substance contains ionic bonds, then its properties would include . .

The bonds between ionic molecules are very strong. The ionic molecules are crystalline solid, have high boiling point, and show electric conductivity in the solution.

Ionic Bond:

This bond is formed between two ions where one is positive and another is negative. Positively charged elements give electrons to negatively charged elements to complete octet.

Example:

Properties of Ionic Compound:

Properties of covalent Compound:

Hence, If a substance contains ionic bonds, then its properties would include solid crystalline state, high melting point and conduct electricity in the solution.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
