Answer:
B: parallel
Explanation:
because a parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.
0.0390 mol thats the answer for your question
1) Calculate the volume from d = m/V => V = m/d = 2.0*10^-23 g / 1.0*10^14 g/cm^3 = 2.0*10^-9 cm^3
2) Now use the formula of volume for a sphere: V = (4/3)π(r^3) =>
r =∛[3V/(4π)] = ∛[(3*2.0*10^-9 cm^3) / (4π)] = 0.48*10^-3 cm = 4.8*10^-4 cm = 0.00048cm
Answer: Ta is Tantalum, Os is Osmium and Rh is Rhodium
Explanation: All of these elements are in the transition metal group. Ta is part of the early transition metals while Os and Rh belongs to the late transition metals.
You can use luminal to make it more visible. Trust me this is the answer because I had this question in my book. Hope it's useful.
