<span>The answer is lactic acid/lactate. This is caused by anaerobic respiration in muscles especially during strenuous physical activity due to low oxygen supply to muscles in respect to the demand. When there is sufficient oxygen in the muscles, pyruvate is broken down aerobically in the Kreb’s cycle. However, it is converted to lactate in the anaerobic pathway. Lactic-acidosis occurs when lactic acid accumulates in tissues and slows down metabolic pathways</span>

________ are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds
olga_2 [115]

<u>Hydrogen bonds </u>are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.

  • The hydrogen bond is weak bond.
  • The hydrogen bond  is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
  • The hydrogen bond is occur in polar , contently bond atoms in different molecules.
  • Example is H-O-H or NH_{3}
  • The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.

The molecular weight of a gas that has a density of 5.75 g/l at stp is __________ g/mol.
Ira Lisetskai [31]

Answer : The molecular weight of a gas is, 128.9 g/mole

Explanation : Given,

Density of a gas = 5.75 g/L

First we have to calculate the moles of gas.

At STP,

As, 22.4 liter volume of gas present in 1 mole of gas

So, 1 liter volume of gas present in \frac{1}{22.4}=0.0446 mole of gas

Now we have to calculate the molecular weight of a gas.

Formula used :

\text{Moles of gas}=\frac{\text{Mass of a gas}}{\text{Molecular weight of a gas}}

Now put all the given values in this formula, we get the molecular weight of a gas.

0.0446mole=\frac{5.75g}{\text{Molecular weight of a gas}}

\text{Molecular weight of a gas}=128.9g/mole

Therefore, the molecular weight of a gas is, 128.9 g/mole
