Copernicus- developed heliocentric model, discovered the chemical element Copernicum has the symbol Cn and atomic number 112, started the scientific revolution.

Brahe- known for his precise and comprehensive astronomical and planetary observations, which heavily influenced future discoveries; built the maps of Hven that helps in accurate determinations of latitude and longitude.

Kepler - solved the mystery of the planets; believed the Solar System's planets orbited the sun in circular path that determined by an arrangement of the five platonic solids.

Galileo - Father of Modern Science; discovered the first moons ever known to orbit a planet other than Earth; first person to study the sky with a telescope; discovered the rings of Saturn; our moon has mountains; Milky Way is made up of stars; established that everything falls to the ground at the same rate regardless of weight; identified the parabola; proposed theory of relativity; discovered pendulums; tried to measure the speed of light; showed the set of perfect squares.

Newton- generalized the binomial theorem; showed sunlight is made up of all the colors of the rainbow; discovered the law of gravitation; Laws of motion and calculus.

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dio
e-lub [12.9K]

Answer:

C6H12O6 —> 2C2H5OH + 2CO2

Explanation:

The equation for the reaction is given below:

C6H12O6 —> C2H5OH + CO2

We can balance the equation above as follow:

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

Now the equation is balanced.

A gas at 400 k is placed in a 4.0 l moveable piston. The gas is cooled to 252 k. What is the new volume of the piston?
katrin [286]

Answer:

2.52L

       

Explanation:

Given parameters:

T₁  = 400K

V₁  = 4L

T₂ = 252K

unknown

V₂ = ?

Solution:

To solve this problem, we are going to apply charle's law. The law states that the volume of a fixed mass of gas is directly proportional to temperature provided pressure is constant.

Mathematically,

               \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

Substitute and solve for V₂

           \frac{4}{400}  = \frac{V_{2} }{252}

        V₂ = 2.52L
