The number of valence electrons in sulfur is 6. In its highest energy occupied electron shell, it has 6 electrons (3s2 and 3p4, summing to 6 electrons, to be exact).
The answer is D. When heated, there is only physical process not chemical process. So the mass of the gas will not change. When heated, according to the thermal expansion, the volume will increase. And the mass is constant, so the density will decrease. Density=Mass/Volume.
Oxygen is used up and glucose is broken down.
Answer:
0.075M
Explanation:
-The concentration of a solution is defined as the mass of the solute divided by the volume of the solution:
-We the solve the molarity problem as follows:
Hence, the concentration of the dilute solution is 0.075M
<h2>The required option d) "specific heat" is correct.</h2>
Explanation:
- To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
- Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
- It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
- Thus, the required "option d) specific heat" is correct.
