These are the characteristics that apply:
- In a solution taste sour: which is consequence of the H+ concentration.
- Corrode metals: the H+ ion reacts with the metal producing a salt and water
-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme:
HA + H2O --> A(-) + H3O(+)
Answer:
The ability of water molecules to form hydrogen bonds with other water molecules and water's ability to dissolve substances that have charges or partial charges are <u>due to water's partial charges.</u>
Explanation:
The partial negative charge on oxygen and partial positive charge on hydrogen enables them to make hydrogen bond and also makes it to dissolve the the other substances having partial charges.
Hey there,
Density = Mass/Valume
D= 3.1/0.35
D= 8.86 g/cm3
Answer:
Explanation:
"The thermal energy moving from her coffee to the tongue" represent the heat.
Here coffee is at high temperature while tongue is at low temperature, when Ixchelt tongue make contact with coffee then thermal energy of coffee is absorbed by tongue and tongue gets burned.
As heat always from high Potential to low that is why heat is absorbed by tongue.
<h2>The distance between students is 2.46 m</h2>
Explanation:
The force of attraction due to Newton's gravitation law is
F = ![\frac{Gm_1m_2}{r^2}](https://tex.z-dn.net/?f=%5Cfrac%7BGm_1m_2%7D%7Br%5E2%7D)
Here G is the gravitational constant
m₁ is the mass of one student
m₂ is the mass of second student .
and r is the distance between them
Thus r = ![\sqrt{\frac{Gm_1m_2}{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BGm_1m_2%7D%7BF%7D%20%7D)
If we substitute the values in the above equation
r = ![\sqrt{\frac{6.673x10^-^1^1x31.9x30.0}{2.59x10^-^8} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B6.673x10%5E-%5E1%5E1x31.9x30.0%7D%7B2.59x10%5E-%5E8%7D%20%7D)
= 2.46 m
