Answer:

The answer is acceleration.

Explanation:

Acceleration- When it comes to science, Force is defined as a "push or pull" of an object with mass that causes it to change velocity.

Balanced Force- This occurs when two forces of the same mass or size are acting on a particular object in opposite direction. The object being acted upon could either stay in its place or move in a uniform speed and direction.

Unbalanced Force- This occurs when the forces applied are not equal and are of different direction. For example, a 55-kg person pulling a 30-kg cart. The cart will move to the direction of the pull.

Thus, when forces acting on an object are unbalanced, it causes the object to accelerate. This acceleration is directly proportional to the "net force", but is inversely proportional to the mass or size.

A net force is the total amount of force that is acting on the object.

What characteristic of an element’s atoms always determines the element’s identity?

dmitriy555 [2]

Answer:

Number of protons

Explanation:

There are three sub atomic particles. These are;

- Protons

- Electrons

- Neutrons

Among these three particles, only one determines the identity of the element. This is the Protons. The number of protons which is also called the atomic number determines the identity of an element. For instance, atom with one proton is Hydrogen and n other element can have atomic number of one.

Which of the following halogens has the weakest attraction for electrons?

Leokris [45]

Answer:

Explanation:

Among the halogens given in this problem, iodine has the lowest attraction for electrons.

This property is known as electronegativity.

Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

As you go down the periodic group the electronegativity decreases.
The most electronegative element on the periodic table is fluorine.
Down the group, iodine is the least electronegative
This is due to the large size of its atom.

How many grams of carbonic acid were produced by the 3.00 g sample of NaHCO

stellarik [79]

I think the given is 3 g sample of NaHCO3. then if it will be reacted with an acid, it will produce H2CO3.
so the reaction NaHCO3 + HCl --> NaCl + H2CO3

mas of H2CO3 = 3 g NaHCO3 ( 1 mol NaHCO3 / 84 g ) ( 1 mol H2CO3 / 1 mol NaHCO3) ( 62.03 g / 1 mol )
mass of H2CO3 = 2.22 g H2CO3
