Hello
its me
and alsooo
the awnser is
number 3 lol
Hi sweetie, hope this helps!
The more salt that is dissolved in the water, the less oxygen will be dissolved in it.
The higher the temperature of the water, the less oxygen will be dissolved it in.
Goodluck!,

Answer: Molecules only speed up when given energy, such as heating. When you heat water enough, it will boil and turn into water vapor. So, therefore, if water's molecules speed up, it will go into the gas phase
Explanation: As that liquid water is further heated, it evaporates and becomes a gas—water vapor. These changes between states (melting, freezing, and evaporating) happen because as the temperature either increases or decreases, the molecules in a substance begin to speed up or slow down.
Hope this helps! ^w^
In the given question, T₁ = 23.40 °C, and T₂ = 24.21 °C,
ΔT = T₂-T₁ = 24.21 - 23.40
= 0.81
Total volume of solution = 50 +50 = 100 ml
Density of solution = 1.0 g/ml
Mass of solution = density × volume = 100 × 1 = 100 gm
q = mcsdT = 100 × 4.184 × 0.81 = 338.9 J
Moles of AgNO₃ = 50 × 0.100 / 1000 = 0.005, similarly moles of HCl is 0.005.
0.005 mol = 338.9 J / 0.005 = 67.78 KJ
ΔHrxn = -45.8 KJ/mol.
