A flow of a electric charge.
Answer:
The percent isotopic abundance of Ir-193 is 60.85 %
The percent isotopic abundance of Ir-191 is 39.15 %
Explanation:
we know there are two naturally occurring isotopes of iridium, Ir-191 and Ir-193
First of all we will set the fraction for both isotopes
X for the isotopes having mass 193
1-x for isotopes having mass 191
The average atomic mass is 192.217
we will use the following equation,
193x + 191(1-x) = 192.217
193x + 191 - 191x = 192.217
193x- 191x = 192.217 - 191
2x = 1.217
x= 1.217/2
x= 0.6085
0.6085 × 100 = 60.85 %
60.85% is abundance of Ir-193 because we solve the fraction x.
now we will calculate the abundance of Ir-191.
(1-x)
1-0.6085 =0.3915
0.3915× 100= 39.15 %
Answer:
The volume is 
Explanation:
From the question we are told that
The number of moles of the gas is 
The volume of the gas is 
The of moles of the gas that leaked is 
Generally from the ideal gas law
Generally at constant pressure and temperature
So 
=> 
=> 
=>
Explanation:
The steps involved in formation of a sedimentary rock are placed in the correct order as follows.
Step 1: The sediment is deposited by wind, flowing water, or other natural processes.
Step 2: The sediment is gradually buried and compacted.
Step 3: Dissolved minerals completely cement the sediment together.
As a result, it leads to the formation of a sedimentary rock.
