Answer: Elements or compounds that enter are Reactants.

The substances that are formed are the Products

Reactants in C6H12O6 + 602 ---> 6CO2 + 6H2O are C₆H₁₂O₆ + 6 O₂

Reactants in 6 CO2 + 6H2O --->C6H12O6 + 602 are 6 CO₂ + 6 H₂O

Reactants in 2 H2 +O2 ---> 2 H2O are 2 H₂ +O₂

Reactants in 2 H2O ---> 2 H2 + O2 are 2 H₂O

Explanation:

The number of atoms in the reactants have to balance with the number of atoms in the products.

The first two examples given are for metabolism of carbohydrates (similar to combustion of hydrocarbons) and photosynthesis.

Liquid nitrogen boils at –195.8°C. Express the boiling point of liquid nitrogen in kelvin

inessss [21]

Answer:

$\boxed {\boxed {\sf 77.35 \ K}}$

Explanation:

The Celsius and Kelvin scales are used to measure the temperature of matter. Their scales and unit differences are the same (1 K increase = 1 °C increase), but they have different starting points.

So, the conversion is quite simple and only requires addition because of the different starting points. The formula is:

$T_K = T_C+ 273.15$

The boiling point of liquid nitrogen is -195.8 °C. We can substitute this value into the formula.

$T_K= -195.8 + 273.15$

$T_K= 77.35 K$

The boiling point of liquid nitrogen is 77.35 Kelvin.
