* The cost of table salt and table sugar is Rs 15 per kg.
and Rs 69 per kg respectively calculate their cost per mole?​

Answers

Cost per mole

Table salt : Rs 0.878

Table sugar : Rs 23.63

Further explanation

Given

Cost table salt (NaCl) = 15/kg

Cost table sugar(sucrose-C12H22O11) = 69/kg

Required

cost per mole

Solution

mol of 1 kg Table salt(NaCl ,MW= 58.5 g/mol) :

[tex]\tt mol=\dfrac{1000~g}{58.5}=17.09~mol=Rs~15\rightarrow 1~mol=Rs~0.878[/tex]

mol of 1 kg Table sugar(C12H22O11 ,MW= 342 g/mol) :

[tex]\tt mol=\dfrac{1000}{342}=2.92~mol=Rs~69\rightarrow 1~mol=Rs~23.63[/tex]

What is the mass of silicon when there are 1.8 x 10^21 atoms of silicon?

Answers

Answer:

Mass = 0.084 g

Explanation:

Given data:

Mass of silicon = ?

Number of atoms of silicon = 1.8 × 10²¹ atom

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³  atoms

1.8 × 10²¹ atom × 1 mole /  6.022 × 10²³  atoms

0.299× 10⁻² mol

0.00299 mol

Mass of silicon:

Mass = number of moles × molar mass

Mass = 0.00299 mol × 28.1 g/mol

Mass = 0.084 g

Please, I really need help. I don't know what to do...

Answers

Answer:

Explanation:

Firstly, let's define what ground and excited state electronic configuration.

Ground state electronic configuration is when the electrons of the atom are in there lowest possible energy level while excited state electronic configuration is when electron(s) have moved to a higher energy level. Examples of these are provided in the options

a. 1s²2s²2p⁴ - This is a ground state electronic configuration (of oxygen) because the electrons are in there lowest possible energy level.

b. This option is not displaying (it is displaying something like an image that isn't loading)

c. 1s²2s²2p³3s¹ - We can see from this that an electron jumped from 2p energy level to 3s (p energy level ought to be completely filled with 6 electrons before another electron moves to the next energy level) meaning the electron is in it's excited state thus this is an excited state electronic configuration (of oxygen).

d. 1s²2s¹2p² - We can see from this also that an electron jumped from the 2s energy level to the 2p energy level (making it 2p² instead of 2p¹ in the ground state). The 2s energy level should ordinarily have 2 electrons. Thus, this is an excited state electronic configuration (of boron).

e. 1s²2s²sp¹ - This is a ground state electronic configuration (of boron) since all the electrons are in there lowest possible energy level.

f. 1s²2s³ - This configuration is impossible because the s energy level should only contain a maximum of 2 electrons, thus impossible to have 3 electrons in the s energy level

98 m/s2
0.5 m/s2
21 m/s2
2 m/s2

Answers

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Acceleration of bike is 0.5 m/s²

Given that:

Force used in push = 7 N

Mass of bike = 14 kg

Find:

Acceleration of bike

Computation:

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

Need help!!! Don’t understand

Answers

A) Neither carbon nor oxygen has satisfied the octet rule

To begin with...

The bond between carbon and oxygen is suppose to have 3 bonds in between

Second:

The lone pairs are not drawn. Since carbon monoxide has 3 bonds in between it should have a lone pair (2 dots) left over on each atom.

Reminder: in order to satisfy the octet rule EACH atom must have 8 electrons. Carbon has 4 valence shell electrons and oxygen has 6. In order to satisfy this rule, there should be 3 bonds in between which makes a total of 6 for each atom plus the lone pairs that make up the 8.

I hope that’s not too confusing, if you still have any questions please let me know in the comments (:

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?

A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
C. An atom of cobalt contains the same number of neutrons and protons.
D. An atom of cobalt contains the same number of neutrons, electrons and protons.

Answers

Answer:

A

Explanation:

27 us the number of protons when we subtract 27 from 59 it will be 32 because a mass number is the sum of proton and neutron but tell u more on the comment

Answer: A - An atom of cobalt contains more neutrons than protons.

Explanation: The atomic number is the number of protons in an atom. The atomic mass is the sum of protons & neutrons in an atom. So, with simple math we can figure out the number of neutrons. Total 59 - 27 protons = 32 neutrons. Which means that A is the only right answer in this case.

Little Extra: A & B would both be correct if Cobalt was a negatively charged ion. An atom is an ion if it is charged, and an ion is either negatively charged or positively charged. For example, if Cobalt had 27 protons & 26 electrons it's overall charge would be positive since it has more protons than electrons. And it would be negatively charged if Cobalt had 27 protons & 28 electrons. No charge if there are 27 protons & 27 electrons because proton +1 and electron -1. Imagine 27-27=0 no charge, 27-26= +1 charge, 27-28= -1 charge
