Answer:
Hello I recently learned inertia so I hope this helps. :))
Do great
1. 1kg I say this because inertia stands for less movement.
2. 5kg because imagine a 5kg ball falling from the sky wouldn't the heavier object speed up faster.
3. A heavier hammer would cause gravity to pull which means it would add more force to it than a light weight toy.
For [Ca +2 ]:
0.0010 mol/l · 0.05 l =
For [ SO4 -2 ] :
0.01 mol/l · 0.05 l =
Cumulative volume:
50 ml + 50 ml = 10 ml = 0.1 l
[Ca +2 ] =
[SO4 - 2] =
Qc for CaSO4:
Qc =
This is less than Ksp of CaSO4.
Answer:
C ) No precipitation will occur.
Answer:
Iodide concentration: 0.02M I⁻
Persulfate concentration: 0.02M S₂O₈²⁻
Explanation:
In chemistry, a dilution is the process in which the concentration of solute is reduced by addition of more solvent.
Iodide (KI → I⁻), has a concentration of 0.20M. If you add 5mL resulting in a final volume of 50mL, the final concentration decreases in:
0.20M × (5mL /50mL) = <em>0.02M I⁻</em>
The persulfate ion (K₂S₂O₈ → S₂O₈²⁻) has a concentration of 0.10M in 10mL that result in a final volume of 50mL. That means final concentration is:
0.10M × (10mL /50mL) = <em>0.02M S₂O₈²⁻</em>

Answer:
The correct answer is:Oxygen is more electronegative than carbon. See the explanation below, please
Explanation:
The electronegativities of oxygen and carbon are: 3, 44 and 2, 55 respectively. The electronegativity is defined as the capacity that a given atom has for the attraction of electrons, by forming a chemical bond. Polarity is related to electronegativity. The greater the difference in electronegativities between two atoms, the polarity of the bond they form will be greater.
