Answer:

A disease caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes.

The severity of malaria varies based on the species of plasmodium.

Symptoms are chills, fever, and sweating, usually occurring a few weeks after being bitten.

People traveling to areas where malaria is common typically take protective drugs before, during, and after their trip. Treatment includes antimalarial drugs.

Why can scientists ignore the forces of attraction between particles in a gas under ordinary conditions

Alika [10]

Scientists ignore the forces of attraction between particles in a gas under ordinary conditions because the particles in a gas are apart and moving fast, rather than clustered and moving slow, therefore the forces of attraction are too weak to have a visible effect.

How many moles of Al are necessary to form 23.6 g of AlBr₃ from this reaction: 2 Al(s) + 3 Br₂(l) → 2 AlBr₃(s) ?

Gnoma [55]

Answer:

0.088 mole of Al.

Explanation:

First, we shall determine the number of mole in 23.6 g of AlBr₃.

This is illustrated below:

Mass of AlBr₃ = 23.6 g

Molar Mass of AlBr₃ = 27 + 3(80) = 267 g/mol

Mole of AlBr₃ =.?

Mole = mass/Molar mass

Mole of AlBr₃ = 23.6 / 267

Mole of AlBr₃ = 0.088 mol

Next, we shall writing the balanced equation for the reaction.

This is given below:

2Al(s) + 3Br₂(l) → 2AlBr₃(s)

From the balanced equation above,

2 moles of Al reacted with 3 mole of Br₂ to 2 moles AlBr₃.

Finally, we shall determine the number of mole of Al needed for the reaction as follow:

From the balanced equation above,

2 moles of Al reacted to 2 moles AlBr₃.

Therefore, 0.088 mole of Al will also react to produce 0.088 mole of AlBr₃.

The enthalpy of vaporization (ΔH°vap) of benzene is 30.7 kJ/mol at its normal boiling point of 353.3 K. What is ΔS°vap at this t

vazorg [7]

Answer: The correct answer is Option c.

Explanation:

Vaporization is defined as the physical process in which liquid particles get converted to gaseous particles.

$Liquid\rightleftharpoons Gas$

The value of standard Gibbs free energy is 0 for equilibrium reactions.

To calculate $\Delta S^o_{vap}$ for the reaction, we use the equation:

$\Delta S^o_{vap}=\frac{\Delta H^o_{vap}}{T}$

where,

$\Delta S^o_{vap}$ = standard entropy change of vaporization

$\Delta H^o_{vap}$ = standard enthalpy change of vaporization = 30.7 kJ/mol = 30700 J/mol (Conversion factor: 1 kJ = 1000 J)

T = temperature of the reaction = 353.3 K

Putting values in above equation, we get:

$\Delta S^o_{vap}=\frac{30700J/mol}{353.3K}=86.9J/(mol.K)$

Hence, the correct answer is Option c.

Which of the following parts of the electromagnetic spectrum have longerwavelengths than those witnessed in the visible spectrum

Vikentia [17]

Infrared radiation is the only one with wavelengths longer than the wavelengths of visible light. X-rays and gamma rays are known to be shorter than visible wavelengths, and cosmic waves are only high energy particles. I hope this helped. And sorry about the late answer...

What are 3 ways to increase the solubility of a solid substance in a solid?

borishaifa [10]

Solubility is the property of a solid/liquid/gaseous chemical substance called the solute, to dissolve in a solvent thus forming a homogeneous solution. Generally the solvent …is a liquid. Solubility of a substance fundamentally depends on the solvent used, the temperature and pressure
