How many neutrons are in an atom of molybdenum-96 (Mo-96)

Which bond is formed when a fatty acid is attached to a glycerol molecule? 2 of 8 QU

Mekhanik [1.2K]

Answer: Heyo Kenji Here! Here's your answer- In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.

Explanation: Hope this helps!

Have a nice day!

Fill in the missing data point. Show all calculations leading to an answer.

Aleksandr-060686 [28]

Answer:

1090 mmHg

Explanation:

We know that with gases we must use a Kelvin temperatures, so let’s try a plot of pressure against the Kelvin temperature.

We can create a table as follows

t/°C T/K p/mmHg

10 283 726

20 293 750

40 313 800

70 343 880

100 373 960

150 423 ???

I plotted the data and got the graph in the figure below.

It appears that pressure is a linear function of the Kelvin temperature.

y = mx + b

where x is the slope and b is the y-intercept.

===============

Calculate the slope

I will use the points (275, 700) and (380, 975).

Slope = Δy/Δx = (y₂ - y₁)/(x₂ -x₁) = (975 -700)/(380 – 275) = 275/105 = 2.619

So,

y = 2.619x + b

===============

Calculate the intercept

When x = 275, y = 700.

700 = 2.619 × 275 + b

700 = 720 + b Subtract 720 from each side and transpose.

b = -20

So, the equation of the graph is

y = 2.619x -20

===============

Calculate the pressure at 423 K (150°C)

y = 2.619 × 423 - 20

y = 1110 - 20

y = 1090

At 150 °C, the pressure 1090 mmHg.

The point is approximately at the position of the black dot in the graph.

5. _______ with the largest atoms and the smallest number of valence electrons and _______ with the smallest atoms and the great

kogti [31]

We have to fill the gap

The correct answer is: Metals with the largest atoms and the smallest number of valence electrons and non-metals with the smallest atoms and the greatest number of valence electrons are the most reactive.

Reactivity of any species depends on ease of release or gain of electron. The species which can release electron easily from valence shell, the species is more reactive whereas the species which can accept electron to its valence shell easily is also more reactive.

Why do you think there is not a periodic table of compounds? Explain with evidence.

Alex787 [66]

Compounds are composed of different elements in a fixed proportions. For example, 1 atom of oxygen (O) combines with 2 atoms of hydrogen (H) to form one molecule of water (H2O) compound. Similarly other numbers of atoms would produce other chemical compounds. Even adding 1 more atom of oxygen would convert the water (H2O) into hydrogen peroxide(H2O2). Even if we were only to list the ones we know there are over 20 million known compounds.

In order to list all possible compounds such a table would rapidly become combinatoric nightmare of such size that it would not be practical to use even with a computer database and it would consist of over 100 billion possible compounds containing only H, C, O and N.

Creating a table to handle all possible elements would mean a table of many trillions of compounds.
