Answer:
B
Explanation:
conduction is the transfer of heat between objects that touch
The correct unabbreviated electron configuration is as below
Vanadium - 1S2 2S2 2P6 3S2 3p6 3d3 4s2
Strontium - 1s2 2S2 2P6 3S2 3P6 3d10 4S2 4P6 4S2
Carbon =1S2 2S2 2P2
<u><em> Explanation</em></u>
vanadium is in atomic number 23 in the periodic table hence its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d3 4s2
Strontium is in atomic number 38 in periodic table hence its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4s2
Carbon is in atomic number 6 in periodic table therefore its electron configuration is 1s2 2s2 2p2
Answer:
The solid crystals disappeared
Explanation:
When a soluble solid solute is added to water, the solid solute disappears after a little while. The disappearance of this solute indicates that the solute has been dissolved in water.
In this case, blue copper sulphate crystals are added to water, the blue crystals disappear leaving only a blue solution. The disappearance of these blue copper sulphate crystals indicates that the substance has dissolved in water.
Answer:
La respuesta es
<h2>158 g</h2>
Explanation:
La masa de una sustancia cuando se le da la densidad y el volumen se puede encontrar usando la fórmula
<h3>masa = Densidad × volumen</h3>
De la pregunta
volumen = 100 mL
densidad = 1.58 g/mL
La masa de sustancia es
masa = 100 × 1.58
Tenemos la respuesta final como
<h3>158 g</h3>

Answer:
Here's what I find
Explanation:
Mercerization involves the treating of cotton fibres with NaOH solution and then drying them under tension.
The process changes the internal structure of the fibres and causes them to swell.
The advantages of mercerization are:
- Greater affinity for dyes (saves money)
- Increased tensile strength
- A high degree of lustre (better appearance)
- Greater absorption of moisture (e.g., sweat)
- Greater resistance to shrinking
