Name three organelles and explain the function of each.

aliya0001 [1]

Mitochondria also contain a double-membrane with the inner membrane folding to form cristae. Also known as the powerhouse, mitochondria.

Conditions inside lysosomes have been shown to be acidic. These conditions are maintained by the lysosome membrane thus providing favorable conditions.

Specifically, ribosomes bind to messenger RNA, abbreviated mRNA. The ribosome reads a series of nucleotide bases in groups of three called codons.

If you have 10.0 g of hydrogen and 5.0 g of oxygen, what mass of the excess reagent remains after the completion of the reaction

mario62 [17]

mass Hydrogen=9.376 g

<h3>Further explanation </h3>

Reaction

2H₂+O₂⇒2H₂O

mass H₂ = 10 g

mol H₂(MW=2 g/mol) :

10 : 2 = 5

mass O₂=5 g

mol O₂(MW=32 g/mol) :

5 : 32 = 0.156

O₂ limiting reactant

mol H₂: mol O₂ = 2: 1, so mol H₂ :

2 x 0.156 = 0.312

mol H₂ :

5 - 0.132 =4.688

mass of H₂ :

4.688 x 2 =9.376 g

At which temperature and pressure would a sample of helium behave most like an ideal gas?

musickatia [10]

Here we have to get the temperature and pressure at which helium gas mostly behaves as ideal gas.

Helium (He) behave most like an ideal gas upto 24K temperature and 0 atm pressure.

The deviation of a real gas to ideal gas occurs at high temperature and low pressure.

The deviation of ideal gas to real gas occurs on taking into account the van der waals' force of attraction between the gas molecules. Now, the van der waals' interaction depends upon the polarisibility of the gas molecule.

As helium (He) is non-polarisable and very small (atomic number 2) it mostly behaves as ideal gas upto 24K temperature and 0 atm pressure.

Although the deviation from the ideal gas behavior to real gas is not so prominent at little high temperature also. Upto 50K it mostly behaves like an ideal gas.
