Answer:
The more acidic the solution the faster it rusts. More Na = more rust
Explanation:
Answer:
Explanation:
Firstly, write the expression for the equilibrium constant of this reaction:
Secondly, we may relate the change in Gibbs free energy to the equilibrium constant using the equation below:
From here, rearrange the equation to solve for K:
Now we know from the initial equation that:
Let's express the ratio of ADP to ATP:
Substitute the expression for K:
Now we may use the values given to solve:
Single replacement/displacement
<h3>Further explanation</h3>
Given
Type involves free element
Required
Type of reaction
Solution
Single replacement/displacement occurs when a more active element replaces another less active element in the compound to form a new compound
The activity of this element can be seen from the voltaic series
<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au </em>
The more to the left, the element is more reactive (easily release electrons) and the stronger reducing agent
The general formula for single replacement :
A + BC ⇒ AC + B
From this general formula shows that <em>there are 2 free elements</em> on both sides (reactants and products)
B: a liquid becomes a gas Let me know if it’s right or wrong
