Answer:
85 cents/L is equal to 3.2176$/gallon.
gas wiuld be heaper to buy from the station A.
Explanation:
As 85 cents/L is more than $2.5/gallon therefore buying gas from station A would be cheaper than the other one.

Answer:
Explanation:
This is a typical double replacement or double decomposition reaction. In this kind of reaction, it involves the combination of ionic compounds which exchange their partners to form new compounds. Typical of these reaction is the formation of precipitates which are insoluble compounds.
The reaction equation is shown below:
AgNO₃
+ K₂SO₄ → 2KNO₃ + AgSO₄
)
From the rule of solubility:
- All trioxonitrate(v) salts are soluble
- Salts of silver sulfates are slightly soluble. This will form the precipitate in the solution.
We can write the ionic equation as:
Ag⁺ + NO₃⁻ + 2K⁺ + SO₄²⁻ → AgSO₄
+ 2K⁺ + NO₃⁻
The spectator ions or non-reactive ions are those ions that appears on both sides of the equation. These ions are the potassium and trioxonitrate ions. We cancel them out to give the net ionic equation of the reaction:
Ag⁺ + SO₄²⁻ → AgSO₄
Answer:
<h2> a. The diffusion of Na ions into the cell is facilitated by the Na concentration gradient across the plasma membrane.</h2>
Explanation:
Cells differ in the concentration of Na+ and many other chemicals inside and out side of the cell, so diffusion of Na+ ions into the cell is facilitated by the Na+ concentration gradient across the membrane.
The diffusion of K+ ions out of the cell is also prevented by the electrical gradient across the plasma membrane.
In the cell, the electro chemical gradient is larger for Na+ than for K+ and many other substances.
Answer:
Mass percent composition describes the relative quantities of elements in a chemicalcompound. For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar massof the compound, multiplied by 100%.
