How many equivalents of pyruvate are needed to generate 1 equivalent of glucose?
kodGreya [7K]
Gluconeogenesis is the process by which the body produce glucose from non-carbohydrate substrates such as pyruvate. To produce glucose from pyruvate, two moleucules of pyruvate is needed. The reaction for the gluconeogenesis reaction is as follow:
2 pyruvate + 4 ATP + 2 GTP + 2 NADH = Glucose + 4 ADP + 2 GDP + 2 NAD + 6Pi.

Suppose the thermometer is miscalibrated to read .3c higher than actual. does this error in calibrations result in the molar mas
andrey2020 [161]
The answer to this question would be: too low

Molar mass would be determined by the number of mol and the mass of the object. Mass wouldn't be influenced by the temperature, but number of mol is. Using ideal gas formula of PV=nRT you can conlude that the amount of mol(n) is inversely related to the temperature (T).
If the temperature is higher than it supposed to be, then the amount of mol would be lower than it supposed to be.

2 What do you notice about the location of the elements in each family?​
sleet_krkn [62]

Explanation:

They are indeed placed from the far left hand side of the periodic table in almost the same column. If you step around the table between left to right, the movement of electrons rises by one. When you progress down the line, the number of power increases by the one.

The atomic number of an element is 71. is this element diamagnetic or paramagnetic?
Mrrafil [7]
The  element  with atomic  number  71(lutetium) is  paramagnetic

  This  is  because  all  its   electrons   is  not  paired .  lutetium  has  electron  configuration  of  (Xe) 4f^14 5d^1 6S^2
Its 5d   sub shell  is  not  paired  since  the  d  sub shell  can  accommodate  a total  of  10   electrons  hence  lutetium  is  paramagnetic

10. When the pressure on a gas inetcases three times, by how much will the volume incrcase or decrease?
blagie [28]

Answer:The answer to this question comes from experiments done by the scientist Robert Boyle in an effort to improve air pumps. In the 1600's, Boyle measured the volumes of gases at different pressures. Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle's law.

Explanation: So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.

BUT, in general, there is not a single answer to your question. It depend by the context.

For example, if you put the gas in a rigid steel tank (volume is constant), you can heat the gas, so provoking a pressure increase. But you won't get any change in volume.

Or, if you heat the gas in a partially elastic vessel (as a tire or a soccer ball) you will get both an increase of volume AND an increase of pressure.

FINALLY if you inflate a bubblegum ball, the volume will be increased without any change in pressure and temperature, because you have increased the NUMBER of molecules in the balloon.

There are many other ways to change volume and pressure of a gas that are different from the Boyle experiment.
