O c. Applying 200 N of force to the chair from the right
O D. Applying 100 N of force to the chair from the right

Answers

In order to overcome static friction, a force greater than 175 N would need to be applied to the chair, so we can eliminate A and D. Since you want to move the chair to the left, you’d have to push from the right, so the correct answer is

A student found the mass of a brick: 50 grams. The volume was 10 cubic centimeters. If the student had 5 bricks, what would be the total density?

Answers

Answer:

The answer is 5 g/cm³

Explanation:

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

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

From the question

The mass of one brick is 50 g

the volume of one brick is 10 cm³

Since the student had 5 bricks

Total mass = 5 × 50 = 250 g

total volume = 5 × 10 = 50 cm³

So the total density is

[tex]density = \frac{250}{50} = \frac{25}{5} \\ [/tex]

We have the final answer as

5 g/cm³

3.Zinc has an atomic number of 30 and a mass number of 65, how many neutrons does it have?
30
65
35
95

Answers

So your answer is 35 right okay so you subtract the mass number and the atomic number and that should always give you the neutrons

Answer:

35

Explanation:

Given parameters:

  Atomic number of zinc  = 30

  Mass number of zinc = 65

Unknown

  Number of neutrons  = ?

Solution:

The mass number of an atom is the sum of its protons and neutrons;

     Mass number  = Protons + neutrons

Atomic number is the number of protons in an atom;

   Atomic number  = Protons

So;

     Mass number  = Atomic number + Neutrons

Neutrons  = Mass number  - Atomic number

 Neutrons  = 65 - 30  = 35

The number of neutrons in the atom is 35

Physical change is defined as the change that changes the physical appearance of the substance and do not affcet the chemical composition of the substance whereas chemical change causes changes in the chemical composition of the susbstance.

The given example shows physical change because solid calcium undergoes sublimation. process in which a solid substance changes into gaseous phase directly without undergoing liquid phase.

Find the percent of oxygen in CaClO3)2 Show your work

Answers

So in calcium chlorate, there is one calcium, 2 chlorines, and 6 oxygens. To find the percent of oxygen in the compound, find the weight of the oxygen and divide it by the total weight of the compound:

weight of oxygen (95.94g/mol) / weight of entire compound (206.98g/mol)
= 0.4635

Finally, to convert this to a percentage you multiply it by 100

0.4635 x 100 = 46.35% Oxygen by mass

It's how many atoms are in two water molecules (H2O)?

Answers

Answer:

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.

Explanation:

:)

The number of atoms present in two water molecules is 6 atoms. 4 hydrogen atoms and 2 oxygen atoms.

What are atoms?

Atoms are the basic unit of a substance. An atom is made of a nucleus, protons, neutrons and electrons. Different atoms combines to form a molecule and molecules combines to form compounds.

Water has the formulas H₂O, thus one molecule of water contains 2 hydrogen and one oxygen. Therefore, two molecules of water that is (H₂O)₂ have 4 hydrogen and 2 oxygens thus, a total of 6 atoms.

Hence, the number of atoms present in two molecules of water is 6.

Why do some transition metals have multiple oxidation states?

Transition metals have multiple oxidation states because of their (a. completely filled b. partially filled c. empty) (s, p, d, or f) sublevel.

Answers

Answer:

because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation

Explaination:

the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.  

Hope this helped you

Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

What are transition metals?

Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.

It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.

Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.

Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.

Oxidation state is defined as the total number of electrons that have been deleted or added to an element.

It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.

Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.
