The significance of melting points are
- it gives us a idea about inter molecular force which binds the particles together.
- at melting point the solid and liquid states exist in equilibrium.
<h3>What is melting point?</h3>
The melting point is the temperature at which a given substance change its physical state from solid to liquid. At this point solids and liquids exist at equilibrium. Melting point of a substance depends on pressure. The melting point of ice increases when pressure decreases. Melting point of a substance decreases by the presence of impurities in it. so you increase or decrease the melting point on any substance by adding more impurities. Ionic bonds, shape and size of molecules are some other factors that affect the melting point.

Answer:
1.97201398 g
Explanation:
Multiply the theoretical yield by the percent yield. Don't forget to move the decimal over 2 on the percent before multiplying or to use the percent button on your calculator.
Answer:
Kindly check the explanation.
Explanation:
NADH is oxidized anaerobic conditions by lactate dehydrogenase because in order to transform or change Pyruvate into Lactate it has to happen in an anaerobic condition that is where we hardly find oxygen(in the presence of no oxygen).
The chemical compound or say the enzyme known as lactate dehydrogenase gets its proton from NADH( in a REDOX type reaction). After getting the proton from NADH, it uses that to convert Pyruvate into Lactate.
NB: the conversion can also be done in aerobic condition but more ATP will be produced. With anaerobic condition, less ATO is produced and there is re-oxidation.
Answer:
See the answer below
Explanation:
<em>The pH scale is important in science because it gives an indication of how acidic or basic a solution is. The scale ranges from 0 - 14 with 0 being the most acidic and 14 being the most basic while a pH of 7 is a neutral pH.</em>
The pH scale is widely applicable in several scientific applications such as in medicine/health, agricultural processes, industrial processes, environmental monitoring, research and development, etc.
In medicine, the pH of the stomach is monitored in order to make some diagnosis. The normal pH of the human stomach ranges from 1.5 - 3.5 and a major deviation from this range can give an indication of wrong health.
In agriculture, the pH condition of the soil on which crops are grown is quite important. While some crops require slightly acidic soil, some will only do well in alkaline soil. Hence, the pH condition of the soil must be monitored to ensure the optimal yield of crops.
Several industrial processes require the monitoring of pH in order to ensure product's quality or monitor some important reactions. In food industries, for example, monitoring the pH of reactions is necessary in order to prevent contamination by pathogens or ensure a good organoleptic quality of the final product. It is also necessary to monitor the pH of industrial wastewaters in order to avoid polluting the environment.
Monitoring pH is also important for environmental monitoring, The pH of various water bodies or soil can give an indication of the level of pollution in the water or the soil.
Answer:
Explanation:
Ksp (BaCO₃) = 5.1 x 10⁻⁹
Ksp (CaCO₃) = 4.8 x 10⁻⁹
Ksp (BaSO₄) = 1.1 x 10⁻¹⁰ = .11 x 10⁻⁹
Since solubility product of BaCO₃ is greatest , its solubility is maximum .It is to be noted that all of them will be giving only two number of ions after dissolution in water .
BaCO₃ = Ba⁺ + CO₃⁻
Ksp = [ Ba⁺²] [ CO₃⁻² ]
= [ Ba⁺²]²
[ Ba⁺²] = √ Ksp
similarly we can find equations for others .
