Answer 1

Answer:

Your friend gave the better response

Explanation:

Formula for density:

Density = mass/volume

p = m/v

Let's substitute the given values into the equation:

p = m/v

p = 23.2/8.593

Solve:

p = 23.2/8.593

p = 2.69987198883

2.69987198883 grams per volume

Notice that 2.69987198883 is the exact answer. Your answer is 2.67, which is inaccurate, even if rounded. If you were to round the exact answer to the nearest hundredth, it would be 2.70 which is not 2.67.

Therefore, your friend gave the better response because it is the correct answer.

Answer 2

density equals mass over volume

23.2/8.593 = 2.69 g/mL

what is the mass of an atom if it has 11 protons, 12 neutrons, and 11 electrons

A,22, B.23, C34, D 11

Answers

Answer:

23, B

Explanation:

The mass of an atom is determined by the number of Protons + Neutrons. Here, if we assume the units is AMU (Which means the mass unit for a proton and neutron would be basically 1), the answer would be 11 + 12 = 23 AMU, which is B.

Answer:

B) 23

Explanation:

Relative Mass = number of protons + number of neutrons

Relative Mass = 11 + 12

Relative Mass = 23

Which of the following occurs when a liquid becomes a gas

Answers

Answer:

Boiling occurs when a liquid changes to a gas below its surface as well as at the surface. The temperature at which a liquid boils is called its boiling point. The opposite of vaporization is called condensation. Sublimation occurs when the surface particles of a solid gain enough energy that they form a gas.Boiling occurs when a liquid changes to a gas below its surface as well as at the surface.

Speed in excess of 100 km/h, which is 208.8 km / h

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

• An equation of uniformly accelerated motion  

[tex]\large {\boxed {\bold {x=xo+vo.t+\frac {1} {2} at ^ 2}}}[/tex]

vt = vo + at  

vt² = vo² + 2a (x-xo)  

x = distance on t  

vo / vi = initial speed  

vt / vf = speed on t / final speed  

a = acceleration  

I think it's not chemistry but physics

Known

Δx = 290 m

vf = 0⇒stop

Δt = 10 s

How much does a sample of C6H12O6 weigh if it contains 1.7 x 10^28 hydrogen atoms?

Answers

Answer:

Explanation:

Glucose  has    6  number  of  carbon  atoms,  12  atoms  of  oxygen  and   6  atoms  of  oxygen

The  total  number  of  glucose  atom is  24  atoms

The  atom  of  hydrogen is twice  that  of   carbon  

that  is (6.02 x10^22) x2=1.204 x10^23atoms

the  number  of  moles  of  hydrogen  is   solved  as   follows

1mole  =  6.02x10^23 atoms  what   about  1.204 x10^23=

{(1.204x10^23)/(6.02 x10^23)}=0.2moles

The  moles  of  glucose

1   atom  of   glucose=  6.02 x10^22  x4 =2.408 x10^23  atoms

moles= { (2.48 x10^23)/(6.02  x10^23)}=0.41moles

Which of the following d shell configurations is likely to be the best magnet?​

Answers

Answer:

D10 is answer

Explanation:

Magnetism can result from unpaired electrons in a given ion of an element, depending on the spin states of the electrons and d10 is fully filled

The d 10 is the d shell configurations which is most likely to be the best magnet.

What are configurations?

Configurations are defined as the way that parts are joined together to form the computer system. The arrangement of electrons scattered throughout the orbital shells and subshells is depicted by the electron configuration of an atom. Divide the periodic table into pieces to represent the atomic orbitals, the areas where electrons are stored, in order to determine an electron configuration. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen to eighteen, and the f-block by the bottom two rows.

Depending on the spin states of the electrons and whether or not d10 is completely filled, magnetism can emerge from unpaired electrons in a specific ion of an element.

Thus, the d 10 is the d shell configurations which is most likely to be the best magnet.

What is the freezing point on this graph?

Answers

Answer:

Point a becuse it is the closest to -5*

Explanation:

Answer:

-5

Explanation:

Negative numbers get you confused.

- = Negative

5 = Number

You know 5 right?

I I I I I - 5

5 is a really less number already.

If you add a negative it will be double small.

Now lets figure out the problem:

What is the freezing point on this graph?

-5 is the smallest number

5 is bigger than -5

15 is bigger than 5 and -5

25 is bigger than all the numbers.

I know what your thinking. 25 is totally not the answer. Its the biggest number. Freezing is a very low number. What number is the lowest out of -5, 5, 15, 25. You see -5.

Therefore, -5 is freezing.
