The combination of seatbelts and airbags can reduce the risk of death in a collision by up to 80%.

The seatbelts help to keep the person in one position and prevent impact with the vehicle as the vehicle comes to a sudden stop. Moreover, the airbag increases the time of collision to reduce the impact experienced by the person. An increased time of collision greatly reduces the damage that is done to the body.

Based on the chemical formula and state of matter, which of these substances will conduct electricity?

Sergeu [11.5K]

Answer:

CuSO4(aq)

Explanation:

The aqueous form of copper sulfate will conduct electricity.

The Solid form will not be a good conductor.

C₅H₁₂ will not conduct electricity

CO₂ will not conduct electricity

Copper sulfate is an ionic compound
In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
This way, they are electrolytes.
In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.

Moles of gas = 0.369

<h3>Further explanation</h3>

Given

P = 2 atm

V = 5.3 L

T = 350 L

Required

moles of gas

Solution

Ideal gas Law

$\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{2\times 5.3}{0.082\times 350}\\\\n=0.369$

Avogadro's law : at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles

moles of O₂ = 45% x 0.369 = 0.166

moles of Ar = 12% x 0.369 = 0.044

moles of N = 43% x 0.369 = 0.159

Calculate the mass of a solid metal cylinder with a density of 2.6 g/cm", a

worty [1.4K]

Answer:

V= π ×r² × h

V = 3.14 × (0.9)² × 4

V = 3.14 × 0.81 × 4

V = 10.1736

Mass = Volume × density

M = 10.1736 × 2.6

M = 26.45136 g
