Endoskeleton
Pros: bones do not get broken so easily
If bones broken, can heal more quick since they are inside with good blood and nutrient supply
Cons: flesh can easily get damage
no shedding of endoskeletons, so no new skeleton cannot if injuried.
Change those up for exoskeletons.. pros for cons and cons for pros
As temperature increases, the molecules and atoms move faster. :^)
Answer:
A precipitate will be produced
Explanation:
The Ksp of AgBr is:
AgBr(s) → Ag⁺ + Br⁻
5.0x10⁻¹³ = [Ag⁺] Br⁻]
<em>Where [] are the concentrations in equilibrium of each ion.</em>
<em />
And if Q is:
Q = [Ag⁺] Br⁻]
<em>Where the concentrations are actual concentrations of each ion</em>
<em />
We can say:
IF Q >= Ksp, a precipitate will be produced
IF Q < Ksp, no precipitate will be produced.
the molar concentrations are:
[AgNO₃] = [Ag⁺] = 0.002M * (50mL / 100mL) = 0.001M
<em>Because 50mL is the volume of the AgNO₃ solution and 100mL the volume of the mixture of both solutions.</em>
[NaBr] = [Br⁻] = 0.002M * (50mL / 100mL) = 0.001M
Q = [0.001M] * [0.001M]
Q = 1x10⁻⁶
As Q > Ksp,
<h3>A precipitate will be produced</h3>
Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves only solids or liquids has no effect on the rate.
Answer:
The answer to your question is: 6 grams of hydrogen
Explanation:
Data
3.0 moles of hydrogen
1.5 moles of oxygen
3 moles of water
# of grams of hydrogen required to form 3 moles of water?
Equation
H₂ + 1/2 O₂ ⇒ H₂O
3 mole 1.5 moles 3 moles
Atomic weight of H₂ = 2 g
1 mole ----------------------- 2 g
3 moles --------------------- x
x = 3(2)/1 = 6 grams of hydrogens
