Answer:
Higher K at very high temperatures.
Explanation:
It is inferred is K is significantly greater at very high temperatures, allowing high production at low cost.
Answer:
2.7×10⁻³ mole
Explanation:
Applying
Q = it.............. Equation 1
Where Q = amount of charge, i = current, t = time
From the question,
Given: i = 0.860 A, t = 5 minutes = (5×60) seconds = 300 seconds
Subsitute these values into equation 1
Q = (0.860×300)
Q = 258 C
If one mole of electron has a charge of 96500 C
Then, x mole of electron will have a charge of 258 C
1 mole ⇒ 96500 C
X moles ⇒ 258 C
Solve for X
X = (258×1)/96500
X = 2.7×10⁻³ mole
An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.
<span>4 amu / (1/1836 amu) = 7344 </span>
<span>Therefore, an alpha particle is 7344 times heavier than an electron.
Hope this answers the question. Have a nice day.</span>
Answer:
3. An oxygen atom with 8 electrons, 8 protons, and 9 neutrons .
Explanation:
if an atom contains equal numbers of protons and electrons, the atom is described as being neutral.
<span>"The theory states that pressure increases with temperature." that is the correct statement I believe.
hope this helps! :-)</span>
