A 5 mole sample of liquid acetone is converted to a gas at 75.0°C. If 628 J are required to raise the temperature of the liquid
velikii [3]
The total energy required for this conversion is equivalent to the sum of the energies that are used. There are three steps:

1) Heating of liquid acetone
This used 628 J

2) Evaporation of acetone
This used 15.6 kJ or 15,600 J

3) Heating of acetone vapors
This used 712 J

Adding these quantities,

Total energy = 628 + 15,600 + 712

The total energy required was <span>16940 Joules of 16.94 kJ</span>

MARKING BRAINLIEST! please help asap, i need a and b, thank you

The time required to reduce the concentration from 0.00757 M to 0.00180 M is equal to 1.52 × 10⁻⁴ s. The half-life period of the reaction is 9.98× 10⁻⁵s.

<h3>What is the rate of reaction?</h3>

The rate of reaction is described as the speed at which reactants are converted into products. A catalyst increases the rate of the reaction without going under any change in the chemical reaction.

Given the initial concentration of the reactant, C₀= 0.00757 M

The concentration of reactant after time t is C₁= 0.00180 M

The rate constant of the reaction, k = 37.9 M⁻¹s⁻¹

For the first-order reaction: C_t =C_0-kt

0.00180 = 0.00757 - (37.9) t

t =  1.52 × 10⁻⁴ s

The half-life period of the reaction: t_{\frac{1}{2} } =\frac{C_0}{2k}

t_{\frac{1}{2} } =\frac{0.00757}{2\times 37.9}

Half-life of the reaction = 9.98 × 10⁻⁵s

Is each of the following very soluble in water? Explain.<br> (b) Sodium hydroxide
vova2212 [387]

The answer is highly soluble

<h3>How does sodium hydroxide dissolve in water?</h3>

When hydroxide (NaOH) dissolved in water, it divides into positively and negatively charged sodium ions (cations) and hydroxide ions (anions). These ions move freely and independently in water, while cations prefer to be surrounded more closely by anions and vice versa.

Although sodium hydroxide is more soluble in hot than in cold water, the process of dissolving sodium hydroxide in water is exothermic.

The unknown compound's insolubility in water might be attributed to its big hydrocarbon group. Because it is dissolved in 5% Naoh, its substituent may be acidic because the interaction with NaOH produces an anion that is soluble in aqueous solution.

How do I draw energy level diagrams?
finlep [7]

Energy levels inside an atom are the specific energies that electrons can have when energy occupies specific orbitals. Electrons can be excited to higher energy levels by absorbing energy from the surroundings, an equivalent light is emitted when an electron returns from a high energy state to a lower one. Representation of this diagrammatic is known as the energy level diagram.

Do you feel that people’s safety is compromised when they live near a nuclear power plant? Why or why not? What sort of informat
Olegator [25]
So, personally, I think it's not that safe to live right by a nuclear plant because it contains radioactive energy and that is unhealthy to the human body. Living by one a person should also take the precautions that it could have a malfunction and that could cause a fatal accident, an explosion. With that radioactive energy is released and both ruins the area and destroys everything. Well my answer is not that great but I hope this helps.
