A 25.0-meter length of platinum wire with a cross-sectional area of 3.50 × 10^−6 meter^2 has a resistanceof 0.757 ohm at 20°C. Calculate the resistivity of the wire. [Show all work, including the equation and
substitution with units.]

Answers

The resistivity of the plantinum wire is 1.06 × 10⁻⁷Ωm

Calculating Resistivity

From the question,

We are to determine the resistivity of the wire

Resistivity can be calculated from the formula

$\rho = (RA)/(l)$

Where $\rho$ is the resistivity of the wire

R is the resistance

A is the cross-sectional area

and $l$ is the length of the wire

From the given information,

R = 0.757 ohm (Ω)

A = 3.50 × 10⁻⁶ m²

$l$ = 25.0 m

Putting the parameters into the formula, we get

$\rho = (0.757 * 3.50 * 10^(-6) )/(25)$

$\rho = 0.10598 * 10^(-6)$

$\rho = 1.0598 * 10^(-7)$

$\rho \approx 1.06 * 10^(-7) \ \Omega m$

Hence, the resistivity of the plantinum wire is 1.06 × 10⁻⁷Ωm

R= (rou * L) / area
where R is the wire resistance
rou: resistivity of the wire material
L : wire length
A : cross section area of wire
by sub.
0.757= (rou*25)/ 3.5*10^-6
25*rou = 2.6495*10^-6
rou= 1.0598*10^-7 ohm.m

A ____________ reaction occurs when a substance is broken down into two or more simpler substances in a chemical reaction.

Answers

Answer: Decomposition

Explanation:

A chemical break down of a reactant into two or more products is known as Decomposition reaction. A substance decomposes to simpler substances.

It can be represented as:

AB → A + B

Example, water breaks down into oxygen and hydrogen

2 H₂O → 2 H₂ + O₂

Thus, the correct answer is:

A Decomposition reaction occurs when a substance is broken down into two or more simpler substances in a chemical reaction.

The reaction is called decomposition reaction in which substance(reactant) breaks down into 2 or more substances (products).
