Answer: molecules


Justification:


1) Given formulas: H₂, H₂O, H₂O₂, CH₄.


2) A molecule is the chemical combination of two or more atoms through covalent bonds.


3) Non-metals only can bond among them by covalent bond, i.e. by sharing electrons.


Two nonmetals cannot bond to each other in other way (ionic bonds) because any of them will not be willing to release an electron completely.


Since the two nonmetal elements just need a few more electrons to complete their respective valence electron shell, they will do it by sharing electrons instead of releasing them.

Sulfur is an element of the periodic table that is not considered a metalloid.

<h3>What is sulfur?</h3>

Sulfur is a chemical element of the periodic table that has the following characteristics:

  • Atomic number 16
  • S symbol
  • Sulfur is classified as a nonmetal
  • It has a yellow color

<h3>What are metalloids?</h3>

Metalloids are a set of chemical elements of the periodic table that are characterized by having an intermediate behavior between metals and non-metals, in terms of ionization energies and binding properties.

It is not easy to distinguish them from true metals. They conduct electrical current better than non-metals, but they are not good conductors like metals. In addition, they are usually very varied in their shape and coloration.

The list of metalloids includes the following elements:

  • Boron (B)
  • Silicon (Si)
  • Germanium (Ge)
  • Arsenic (As)
  • Antimony (Sb)
  • Tellurium (Te)
  • Polonium (Po)

Which option defines kinetic energy?(1 point)
MAVERICK [17]

The option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

The correct answer choice is option c

In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.

<h3>What is energy?</h3>

Energy can simply be defined as the capacity of doing work.

Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.

The unit of energy joules.

Other examples of derived quantities just like energy too are:

  • Volume
  • Speed
  • Acceleration
  • Density.
  • Upthrust
  • Momentum
  • Momentum
  • Power
  • Pressure
  • Force

Below are some few forms of energy; these are:

  • Kinetic energy
  • Potential energy
  • Mechanical energy
  • Solar energy
  • Light energy
  • Chemical energy

So therefore, the option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

What is the density at 20 degrees Celsius of 12.0 mL of a liquid that has a mass of 4.05g?​
zmey [24]

Answer:

<h3>The answer is 0.34 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{4.05}{12}  \\  = 0.3375

We have the final answer as

<h3>0.34 g/mL</h3>

Hope this helps you
