Answer: Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

It changes with new evidence.

The example shows that science changes with new evidence. Science can not change with common beliefs because first of all beliefs should be proved and become evidence. Second, science is not fixed because of the scientific method and experimentation, which is a phase of the scientific method.

¿Qué volumen ocuparán 12 g de hierro?

sasho [114]

Answer:

$\large\boxed{\large\boxed{volume=1.5cm^3}}$

Explanation:

Translation:

What volume will 12g of iron occupy?

<h2>Solution</h2>

Iron is a solid substance at room temperature. You can find the volume of solids (and of not solids) using the density.

$Density=\dfrac{mass}{volume}$

You can obtaindthe density of most pure substances in the internet. The density of iron at room temperature is 7.874 g/cm³.

Thus, substituting in the formula, you get:

$7.874g/cm^3=\dfrac{12g}{volume}\\ \\ \\ volume=\dfrac{12g}{7.874g/cm^3}\\ \\ \\ volume=1.5cm^3$

The answer is rounded to two significant figures because the input, 12g, has two significant figures.

Patient added a 17-g measured dose of polyethylene glycol 3350 (MIRALAX) to 180 mL of water to use as a laxative. If the volume

Sergio [31]

Answer: Apparent density of ethylene glycol 3350 = 17g/15.6mL= 1.09g/mL

Specific gravity of mixture = 1.01

Explanation:

The specific gravity of an object or substance is the ratio of the density of that object or substance to that of a reference substance usually water.

Specific gravity = density of substance/density of water

The density of a substance is the ratio of the mass of that substance to is volume.

Density = Mass/volume

Density of water 1.00 g/mL,

Apparent density of ethylene glycol 3350 = mass/volume

volume of ethylene glycol = volume of mixture - volume of water

volume of ethylene glycol = 195.6 - 180) = 15.6mL

Apparent density of ethylene glycol 3350 = 17g/15.6mL= 1.09g/mL

mass of water = density of water * volume of water

mass of water = 1.00g/mL * 180mL = 180 g

Mass of solution = mass of substance + mass of water = (17 + 180)g = 197g

Density of mixture = mass of mixture / volume of mixture

Density of mixture = 197 g / 195.6 mL = 1.01 g/mL

specific gravity of mixture = density of mixture / density of water

specific gravity of mixture = 1.01g/mL / 1.00g/mL

specific gravity of mixture = 1.01
