The H+ concentration in the lake has increased as a result of the acid rain.
The original pH of the lake was 7, which mean the water is neutral, but due to the acid rain, it drops to 5. This means, that the water has become acidic and how have more hydrogen ion. The H+ concentration in the lake has 100 times compares with its original pH.
Answer:
Pure Glycol
For example,
Antifreeze will freeze at minus 34 degrees.
Also prevents your car from freezing up because of the Pure Gycol in it.
Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:
Heat = mC(T2-T1)
Heat = 5(0.90)(32.1 - 22.1)
Heat = 45 J energy gained
Answer:
NaNO₃
KNO₃
Ca(NO₃)₂
Explanation:
The possible cations for the salt. = Na⁺ , K⁺ , Ca²⁺
The anion for which the formula has to written = NO₃⁻
The salt is of white color.
The possible salts may be:
<u>NaNO₃ </u>
<u>KNO₃</u>
<u>Ca(NO₃)₂</u>
Missy Mae can have one of these salts.
The color of NaNO₃ is from transparent to white.
The color of KNO₃ is white.
The color of NaNO₃ is from white to light grey.
