Answer:

1. SI units are easy to remember

2. English system needs lots of calculation while converting it from one unit to other

3. SI unit is universally accepted.

Explanation:

1. SI units are easy to remember

2. English system needs lots of calculation while converting it from one unit to other.

in SI unit base 10 is used to convert from one unit to other,I is similar to number system, therefore it is very easy to remember and convert between units.

In  English system it is very difficult to memorize when we have to convert bigger unit to smaller unit by several orders of magnitude and it needs lots of calculation.

Example:

Suppose we have to determine how many millimeters are there in a meter? then we can easily determine

we can easily remember it as milimeter means 10^3meter

on the other hand if we have convert microns into a mile than it needs lots of calculation.

3. SI unit is universally accepted.

What are the boiling point and freezing point of a 0.40 m solution of sucrose in ethanol?
dimulka [17.4K]

The solution would be like this for this specific problem:

For freezing point

Tf, soln= -114.6-(i*Kf*m) 
Tf, soln= -114.6 - (1*1.99*0.40) 
Tf= -115.4 C 

 

For boiling point:

Tb=78.4+(i*Kf*m) 

Tb=78.4+(1*1.99*.40) 
Tb= 79.2 C 

So the boiling and freezing point of a 0.40m solution of sucrose in ethanol is 79.2 C and  -115.4 C respectively.

The ksp value for lead(ii chloride is 2.4 × 10?4. what is the molar solubility of lead(ii chloride?
charle [14.2K]
Molar solubility is number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated. 

The molar solubility of lead(ii) chloride with ksp value of 2.4 × 10e4 can be solve as: 

Ksp = s2 = 2.4 × 10e4
s2 = 2.4 × 10e4
s = √(2.4 × 10e4)
s =  154.9 mol/L

When electrons move through a series of electron acceptor molecules in cellular respiration ________.
Verizon [17]

Answer:

oxygen is reduced to form water.

Explanation:

Cellular respiration

It is the set of reactions in which the ac. Pyruvic produced by glycolysis is split into CO2 and H2O and 36 ATP are produced. In eukaryotic cells breathing is performed in the mitochondria. It occurs in two stages:

- PIRUVATE OXIDATION

- AC CYCLE TRICARBOXYL

The "problem" with fermentation is that, by using organic molecules as terminal electron acceptors and having to dispose of the resulting product (lactic acid / ethanol) as waste, the potential energy of these compounds is lost.

The alternative solution is to use some non-organic molecule that can accept electrons and thus become a reduced molecule. Oxygen is perfect for this, because after receiving the electrons it combines with two protons, thus becoming the perfect liquid residue for the environment: H2O.
