Answer:

A single element or many elements

Step-by-step explanation:

A molecule consists of <em>two or more atoms</em> of the same or different elements that are bound together.

Examples of molecules are O₂, H₂O, CH₂O, and C₂H₃OCl.

C is <em>wrong</em>, because a molecule must contain at least two atoms.

Answer: Option (a) is the correct answer.

Explanation:

When two or more atoms are chemically combined together then the product formed is known as a molecule.

These atoms can be bonded through either covalent or ionic bonds.

For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is $H_{2}O$ .

Thus, we can conclude that an element can be made of many elements.

Can one atom in this type of reaction win the "tug of war"? What might happen if it did?

Luden [163]

Answer:

POLAR BONDS will form.

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.

The results of the gold foil experiment led to the conclusion that an atom is

viva [34]

$\sf\large \blue{\underbrace{\red{Answer⋆}}}:$

The nucleus of an atom of the element is positively charged and atom has a hollow space inside it.

Explanation:

This experiment was conducted by Rutherford in this experiment. He placed a gold foil and surround it with a screen.

And He exposed gold foil in alpha particles rays in which he noticed that most rays passed through atom which conclude that atom has a large space, some rays get deflected and some reverse their path this show that the positive charge of nucleus of an atom.

The public is not yet able to purchase hydrogen fuel cell powered cars because engineers have to determine how the cars perform

muminat

The given question is incomplete the options of the compete are:

A. On racecar tracks

B. In real-world conditions

C. In flooded environments

D. On closed courses

Answer: In real world conditions.

Explanation:

Fuel cell vehicles use hydrogen has as a fuel in order to run the car. Unlike the other conventional vehicle that run on fossil fuels and gasoline.

The hydrogen and oxygen combines together in order to power the the motor in the car. The electricity produced by the combination of this runs the car and the waste product is water.

They are also called as electronic cars but the main problem is that it has not been yet tested in the real world. There are many more physiological conditions that differ from place to place in the real world conditions.

Firstly, the cars needs to be tested in the real world and see where there are any advantages and disadvantages over conventional vehicles.

Hence, it is not available to the general public for purchase.
