Consider a balloon of nitrogen gas and a crystal of sugar sitting on a table at room conditions. Select the appropriate statemen
yKpoI14uk [10]

Answer:

about the same

Explanation:

Thermal energy is constant at a certain temperature in general. The energy is denoted by K_BT

Where,

K_B is the Boltzmann constant

T is the absolute temperature

Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.

Thus,

The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.

How many moles of agcl are contained in 244 ml of 0.135 m agcl solution. the density of the solution is 1.22 g/ml?
Zanzabum

Answer is: 3,94·10⁻² moles of silver chloride are contained in 244 ml of solution.

V(AgCl) = 244 ml = 0,244 l.

b(AgCl) = 0,135 mol/kg.

d(AgCl) = 1,22 g/ml.

m(AgCl) = V(AgCl) · d(AgCl).

m(AgCl) = 244 ml · 1,22 g/ml.

m(solution AgCl) = 297,68 g.

m(AgCl) = 0,135 mol ·143,3 g/mol = 19,34 g.

ω = 19,34 g ÷ 19,34 g + 1000 g = 0,0189.

m(AgCl) = 0,0189 · 297,68 g = 5,64 g.

n(AgCl) = 5,64 g ÷ 143,3 g/mol = 0,0394 mol.

Why are alloys useful?
zalisa [80]

Answer:

Explanation:

People make and use alloys because metals don't have exactly the right properties for a job. usually, alloys are stronger and harder than their main metals, harder to work and less ductile (harder to pull into wires).
