Among the choices provide above the <span>redox reactions do you expect to occur spontaneously in the forward direction is the below:
</span><span>Fe2+(aq) + Zn(s) -> Fe(s) + Zn2+(aq)
</span><span> Al(s) + 3Ag+(aq) -> Al3+(aq) + 3Ag(s)
</span>
<span>Those reactions will proceed when the metal that is a solid is higher up in the electromotive series than the metal that is an ion (dissolved).</span>
The answer is 20 because in an atom no of protons equal no of electrons
Awnser: independent variable or control
Explanation:
Answer:
The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change
Answer:
Partial pressure of ammonia is 0,28.
Explanation:
For the reaction:
NH₄HS(s) ⇄ NH₃(g) + H₂S(g)
kp = 0,080 is defined as:
0,080 = P[NH₃] P[H₂S] <em>(1)</em>
Where P[NH₃] is partial pressure of NH₃
Asuming amount of NH₄HS is 1, equilibrium concentration for each compound is:
[NH₄HS] = 1 - x
P [NH₃] = x
P [H₂S] = x
Replacing in (1):
0,080 = X×X
0,080 = X²
X = 0,28 = P[NH₃]
