The density is 4 g/cm³ or 4000 kg/m³.
Density = mass/volume = 12 g/3 cm³ = 4 g/cm³
The measurement of 4 g/cm³ is already in <em>SI units</em>.
In SI <em>bas</em>e units,
Density = (4 g/1 cm³) × (1 kg/1000 g) × (100 cm/1 m)³ = 4000 kg/m³
Answer:c
Explanation: just took the test
The lowest is at the bottom right and the highest is at the top right I think
A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L
B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L
Hoped this helped ( I believe it's right, sorry if it's not )
The solubility product expressions for the CuBr, ZnC₂O₄ and Ag₂CrO₄ will be represented as [Cu⁺][Br⁻], [Zn²⁺][C₂O₄²⁻] and [Ag⁺]²[CrO₄²⁻] respectively.
<h3>What is solubility product expressions?</h3>
The solubility product expression or constant is denoted by Ksp, and it is the equilibrium constant for a solid substance dissolving in an aqueous solution.
- Balanced chemical reaction of CuBr is CuBr → Cu⁺ + Br⁻ and value of Ksp will be written as Ksp = [Cu⁺][Br⁻].
- Balanced chemical reaction of ZnC₂O₄ is ZnC₂O₄ → Zn²⁺ + C₂O₄²⁻ and value of Ksp will be written as Ksp = [Zn²⁺][C₂O₄²⁻].
- Balanced chemical reaction of Ag₂CrO₄ is AgCrO₄ → 2Ag⁺ + CrO₄²⁻ and value of Ksp will be written as Ksp = [Ag⁺]²[CrO₄²⁻].
Hence balanced equations with solubility product expressions will be shown above.
