Which information can be determined using half-life?

Firlakuza [10]

In,radioactive decay,the half-life is the length of time after which there is a 50 percent chance that an atom will have undergone nuclear decay.It varies depending on the atom type and isotope,and is usually determined experimentally.

PLEASE HELP ASAPP!!!

Answer:

hello

Explanation:

for average speed the total distance is important so.

and you must convert min to hour 15 min is 1/4 or 0.25 hour

$s = \frac{x}{t} = \frac{12}{0.25} = 48 \frac{km}{h}$

for average velocity the straight line distance is important so

$v = \frac{d}{t} = \frac{8}{0.25} = 32 \frac{km}{h}$

hope you understand

A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of

GREYUIT [131]

Given:

Sample 1:

Chloroform is $CHCl_{3}$

12 g Carbon

1.01 g Hydrogen

106.4 g Cl

Sample 2:

30.0 g of Carbon

Solution:

mass of chloroform from sample 1:

12 + 1.01 +106.4 =119.41 g

Now, for the total mass of chloroform in sample 2:

mass of chloroform $\times$ $\frac{given mass of carbon}{mass of carbon atom}$

mass of chloroform = 119.41 $\times$ $\frac{30}{12}$ = 298.53 g
