D please mark I brainliest I need them lol
Answer:
0,61 moles of potassium permanganate equal 3.67 x 10^23
Explanation:
The mole is defined as the amount of compound that contains Avogadro's number of particles (atoms, molecules, ions, electrons, etc.). Avogadro's number has a value of: 6,023 · 10e23 particles.
6,023 · 10e23 particles.---1 mol KMn04
3.67 x 10e23 particles-----x=
x= ( 3.67 x 10xe23 particles1 mol KMn04 )/6,023 · 10e23 particles=0,609 moles
A=dv/ dt
a=(v2-v1)/(t2-t1)
a=(60-50)/(10-0)
a=10/10
a=1
it's acceleration is 1 km/s^(2) or 1000 m/s^(2)
Hope I can help u
Alpha (α), beta (β-) and gamma (γ) decay. When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. These are called radioactive isotopes. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation.
2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver
