The resistance of a wire is not dependent on

Chemistry

Cloud [144]3 years ago

Answer: D) current

Explanation:

Resistance is the opposing force to the motion of the charges which constitute current.

The resistance increases with increase in temperature and length of the wire but decreases with the diameter.

It does not depend on the current.

Resistance is given by:

R =\frac{\rho l}{A}=\frac{4\rho l}{\pi d^2}

where, ρ is the resistivity, l is the length of the wire, A is the area of cross-section and d is the diameter.

Other then these factors, the resistance increases with increase in temperature. This is because at higher temperature, the collision between electrons positive kernels increases which restricts the motion of electrons. This increases the resistance.

Answer:

Part 1: W = 116 Y = 163

Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.

Why Is Any Chemical Reaction always Balanced? Give reasons and Explain the Easiest way to solve the Balancing Problems in Chemic
erastova [34]

Answer:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.

What is the mass percent of oxygen (0) in SO2?
vazorg [7]

Answer:

D. (16.0 g + 16.0 g) × 100% / (32.1 g + 16.0 g + 16.0 g) = 49.9%

Explanation:

Step 1: Detemine the mass of O in SO₂

There are 2 atoms of O in 1 molecule of SO₂. Then,

m(O) = 2 × 16.0 g = 16.0 g + 16.0 g = 32.0 g

Step 2: Determine the mass of SO₂

m(SO₂) = 1 × mS + 2 × mO = 1 × 32.1 g + 2 × 16.0 g = 32.1 g + 16.0 g + 16.0 g = 64.1 g

Step 3: Detemine the mass percent of oxygen in SO₂

We will use the following expression.

m(O)/m(SO₂) × 100%

(16.0 g + 16.0 g) × 100% / (32.1 g + 16.0 g + 16.0 g) = 49.9%

A single atom is in a balanced electrical state.
slega [8]
I believe the answer is: Protons and Neutrons
Protons weigh 1 amu while neutrons also weigh 1 amu. I’m not sure if they are talking about how many there is.
