The number of moles in 4.27×10^22 particles of silver is
bazaltina [42]

Answer:

mol=0.0709mol

Explanation:

Hello,

In this since one mole equals 6.022x10²³ particles of silver by means of the Avogadro's number, we can compute the moles in 4.27x10²² particles as shown below:

mol=4.27x10^{22}particles*\frac{1mol}{6.022x10^{23}particles}\\\\mol=0.0709mol

Best regards.

A 4.000 g sample of iron was heated from 0.0°C to 21.0°C. If it has a specific heat of 0.440 kJ/kg °C, how many kilojoules of he
Mashutka [201]
M = 4 g = 4/1000 kg = 0.004 kg, θ₂ = 21.0°C, θ₁ = 0°C , c = 0.44kJ/kg°C,

Q = mc(θ₂ - θ₁)

Q = 0.004*0.440*(21 - 0)

Q  =  0.03696 kJ 

0.03696 kJ<span> of heat is absorbed.</span>

What is the primary difference between a hypothesis and a theory? A theory is supported by more data and observations than a hyp
Akimi4 [234]
The primary difference between a hypothesis and a theory is that a hypothesis is falsifiable but a theory has been proven to be correct. An hypothesis is a proposed explanation put forward on the basis of limited evidence as a commencement point for further investigation, at the end of the investigation the theory may not be accepted if it failed to meet some criteria. A theory is a proven system of ideas used to explain a particular phenomenon.

Which electron configuration represents a selenium atom in an excited state?(1) 2-7-18-6(2) 2-7-18-7(3) 2-8-18-6(4) 2-8-18-7
rosijanka [135]
(2) 2 - 7 - 18 - 7 does, because the electron from the L shell jumped to the N shell, which requires energy.

The rest of them are either different types of atoms (different elements) or are not the excited state (ground state)

Which of the following aqueous solution will have the highest boiling point
Sliva [168]

Ionic molecules have higher boiling point than covalent molecules.

So that leaves Na2SO4 and NaCl.

The ionic molecule with higher charge will have higher boiling point.

Na2SO4 have ions with charge +-2.

NaCl have ions with charge +-1.

So the answer is C.
