The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .

Answers

Answer: the 1st answer is neutrons and i think the 2nd is nucleus

Explanation:

The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.

What is atomic mass?

The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.

The atomic mass of an element = No. of protons + No. of neutrons

The atomic mass of an element = No. of electrons + No. of neutrons

The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.

As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.

For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume

Answers

Answer:

The answer is 200 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density}\\[/tex]

From the question

mass = 150 g

density = 0.75 g/cm³

We have

[tex]volume = \frac{150}{0.75} \\ [/tex]

We have the final answer as

200 cm³

A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s

Answers

Answer:

The answer is option D

Explanation:

To find the speed given the kinetic energy and mass we use the formula

[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]

We have the final answer as

3.6 m/s

Which elements form covalent bonds? Which other element is included in the group?

Answers

covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between elements that are far apart on the periodic table.
