Answer:
2450 cm3
Explanation:
Volume of cylinder = V=πr2h
2.45L = 2450mL
1mL = 1 cm cubed
2450mL = 2450 cm cubed
Answer:
Polonium: <em>Number</em><em> </em><em>of</em><em> </em><em>protons</em><em> </em><em>=</em><em> </em><em>8</em><em>2</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Number</em><em> </em><em>of</em><em> </em><em>neutrons</em><em> </em><em>=</em><em> </em><em>2</em><em>0</em><em>6</em>
Sodium: <em>Number</em><em> </em><em>of</em><em> </em><em>protons</em><em> </em><em>=</em><em> </em><em>1</em><em>1</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Number</em><em> </em><em>of</em><em> </em><em>neut</em><em>rons</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em>
The rate law for a reaction that is first order in both reactants is Rate=k[A][B]. Therefore to find the rate you plug in the values you are given to get the equation rate=0.5×0.0183×0.0168 to get Rate=1.54×10⁻⁴ mol/Ls.
I hope this helps. Let me know in the comments if anything is unclear.
Standard Temperature and Pressure (STP) is 0 degree Celsius and 1 atm. We also know that 1atm= 101.3 kPa. Thus, set 3 is the best choice.
Hope that would help :))
