Answer:
Carbon tetrachloride would be 2.2 fold heavier than water
Explanation:
Carbon tetrachloride (2.20g/mL) is denser than water (1.00g/mL)
Explanation:
A solid compound formed by chemical reaction of a positively charged cation with a negatively charged anion is known as ionic solid. Ionic bonds exist between an ionic solid.
When dissolved in water, ionic solids dissociate into ions. Hence, they are able to conduct electricity as electricity is the flow of ions or electrons.
A molecular solid is a solid in which molecules are held together by Vander waal forces. They do not conduct electricity as there is no unbalanced charge on the compound.
Solids in which atoms of metal are held together by metallic bonds are known as metallic solids. These conduct electricity when present in solid state for bond overlap.
A covalent solid is a substance in which atoms are held together by covalent bonds. They do not conduct electricity and have high melting point.
Thus, we can conclude the following.
- A >1000 °C does not conduct electricity : Covalent solids
- B 850 °C conducts electricity in the liquid state, but not in the solid state : Ionic solid
- C 750 °C conducts electricity in the solid state : Metallic solid
- D 150 °C does not conduct electricity : Molecular solid
Solid - Retains its shape no matter the container
Gas - Particles move freely but dont go far
Liquid - Expands to fit the volume of container
Plasma - I guess the oter thing

Answer:
4.59 × 10⁻³⁶ kJ/photon
Explanation:
Step 1: Given and required data
- Wavelength of the violet light (λ): 433 nm
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Convert "λ" to meters
We will use the conversion factor 1 m = 10⁹ nm.
433 nm × 1 m/10⁹ nm = 4.33 × 10⁷ m
Step 3: Calculate the energy (E) of the photon
We will use the Planck-Einstein's relation.
E = h × c/λ
E = 6.63 × 10⁻³⁴ J.s × (3.00 × 10⁸ m/s)/4.33 × 10⁷ m
E = 4.59 × 10⁻³³ J = 4.59 × 10⁻³⁶ kJ
