a tester is a person who test something especially a new products
Greater absolute charge
- This is because ionic bond results from stronger electrostatic forces of attraction.
- The higher the value of charges q₁ and q₂ the stronger will be the ionic bond.
<em>Answer:</em>
Explanation:
<em>Formula:</em>
Where Nt is the amount of substance remaining after time t,
N0 is the amount of substance at time t = 0,
t is the time at which we have to find out how much substance disintegrated from t = 0 to t = t
& t_1/2 is the half life corresponding radioactive sample.
<em>Given:</em>
N0 = 200g
t= 40 days
t1/2 = 4 days
<em>To find:</em>
Nt =?
<em>Solution:</em>
Substituting given data in above formula,

<span>You must multiply the bond enthalpy by each broken or formed bond.
The C - H bond = 414k Joules/ mol, but that is only applicable per bond.
The C3H8 molecule has 8*C-H bonds that have to break. You have to account all the bonds that break and form to get the DH for the reaction.
Because of the Lewis structure of Propane C3h8 you only use 8 in </span><span>c3h8 has 3-C and 8-C.</span>
