The correct answer is cell theory.

It states that :

1. All living organisms are made of cells.

2. The cell is the basic unit of life

3. Cells arise from pre - existing cells.

The modern version of cell theory adds the following:

4. Energy flow occurs within cells.

5. Hereditary information, namely DNA, is passed from cell to cell.

6. All cells have the same basic chemical composition.

The cell theory was proposed by three  German scientists called Theodore Schwan, Rudolf Virchow and Mathias Schleiden.

4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
vovangra [49]

Answer:

0.36g

Explanation:

Given parameters and conversion to standard unit

 To solve this problem we must assume ideality

Volume of N₂H₄  =  350mL  = 0.35dm³

Temperature of container  = 50°C  = 50 + 273  = 323K

Pressure  = 885torr;

               760torr  = 1atm

               885torr  = \frac{760}{885}   = 0.86atm

Unknown:

Mass of the compound  = ?

Solution:

The mass of the compound can be derived using the expression below;

         Mass = number of moles x molar mass

molar mass of N₂H₄ = 2(14) + 4(1)  = 32g/mol

To find the number of moles;

       PV  = nRT

          n  = \frac{PV}{RT}

P is the pressure

V is the volume

R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

         n  = \frac{0.86 x 0.35}{0.082 x 323}   = 0.01mole

So,

    Mass  = 0.01 x 32  = 0.36g
