Based on the Hertzprung-Russell diagram, which statement is true? OA. Main sequence stars with low temperatures tend to have low
ololo11 [35]

Main sequence stars with low temperatures tend to have low luminosity is based on Hertzprung-Russell diagram

<h3>What is the Hertzsprung-Russell diagram's main sequence?</h3>

The bright, hot stars in the image's upper left are the main sequence group, which stretches roughly diagonally to the lower right (dim and cool). In the bottom left are white dwarfs, which are small, faint, and hot. In the top right are giant and supergiant stars, which are big, bright, and cool.

<h3>What is the main sequence star H-R diagram trend?</h3>

Main sequence stars have a wide range of effective temperatures, but because they are brighter at higher temperatures, they normally follow a band from the bottom right to the top left of the diagram. Inside the cores, hydrogen and helium are fusing together.

Using the average atomic mass, calculate the mass in grams of 143 iron atoms
melomori [17]

Answer:

1326.6 × 10⁻²³g

Explanation:

Given data:

Number of atoms of iron = 143 atoms

Average atomic mass of iron = 55.845 amu

Mass of iron = ?

Solution:

It is known that,

55.845 g of iron = one mole of iron = 6.02× 10²³ atoms

For 143 atoms:

143 atoms /6.02× 10²³ atoms × 55.845 g

23.754 × 10⁻²³× 55.845 g

1326.6 × 10⁻²³g

What is the standard cell notation for a galvanic cell made with silver and nickel?
MA_775_DIABLO [31]
Answer:

<span>Ni<span>(s)</span><span><span>∣∣</span>N<span>i<span>2+</span></span><span>(aq)</span> <span>∣∣</span></span><span><span>∣∣</span> A<span><span>g+</span><span>(aq)</span></span><span>∣∣</span></span>A<span>g<span>(s)</span></span></span>

Explanation:

Start by finding the standard reduction potential for the <span>A<span>g+</span></span> and <span>N<span>i<span>2+</span></span></span> ion. Normally, the values are listed at the back of most chemistry textbooks.

<span>A<span><span>g+</span><span>(aq)</span></span>+1<span>e−</span>→A<span>g<span>(s)</span></span> <span>Eo</span>=0.80 V</span>
<span>N<span>i<span>2+</span></span><span>(aq)</span>+2<span>e−</span>→Ni<span>(s)</span> <span>Eo</span>=−0.23 V</span>

In the galvanic cell, the reaction is spontaneous and for a spontaneous reaction <span>E<span>o<span>cell</span></span></span>must be a positive quantity.

<span><span>E<span>o<span>cell</span></span></span>=<span>E<span>o<span>Anode</span></span></span>+<span>E<span>o<span>cathode</span></span></span></span>

Manipulate the two equations so that <span>E<span>o<span>cell</span></span></span> is positive. Note that the anode is the site of oxidation (where electrons are lost) and the cathode (where electron are gained) is the site for reduction.

<span>A<span><span>g+</span><span>(aq)</span></span>+<span>1<span>e−</span></span>→A<span>g<span>(s)</span></span> <span>Eo</span>=0.80 V</span>
<span>Ni<span>(s)</span>→N<span>i<span>2+</span></span><span>(aq)</span>+<span>2<span>e−</span></span> <span>Eo</span>=0.23 V</span>

<span>2×<span>{A<span><span>g+</span><span>(aq)</span></span>+1<span>e−</span>→A<span>g<span>(s)</span></span>}</span> <span>Eo</span>=0.80 V <span>(Cathode)</span></span>
<span>Ni<span>(s)</span>→N<span>i<span>2+</span></span><span>(aq)</span>+2<span>e−</span> <span>Eo</span>=0.23 V <span>(Anode)</span></span>
<span> <span>−−−</span></span>
<span>2A<span><span>g+</span><span>(aq)</span></span>+Ni<span>(s)</span>→N<span>i<span>2+</span></span><span>(aq)</span>+2A<span>g<span>(s)</span></span> <span>E<span>o<span>cell</span></span></span>=1.03 V</span>

Start with the anode components (site of oxidation) - the cathode components are listed to the right.

<span>Ni<span>(s)</span><span><span>∣∣</span>N<span>i<span>2+</span></span><span>(aq)</span> <span>∣∣</span></span><span><span>∣∣</span> A<span><span>g+</span><span>(aq)</span></span><span>∣∣</span></span>A<span>g<span>(s)</span></span></span>

The single vertical lines indicate the boundary (phase difference) between solid <span>Ni</span>and <span>N<span>i<span>2+</span></span></span> ions in the aqueous solution of the first compartment and between solid <span>Ag</span> and <span>A<span>g+</span></span> ions present in the aqueous solution of the second compartments.

The double vertical lines refer to the salt bridge - note that the salt bridge must be an inert salt to both ions present in both compartments of the galvanic cell ...
