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

Calculate the number of protons and neutrons for ²⁴Mg and 88Sr.
Answer:
12 protons and 12 neutrons are present in Mg and
38 protons and 50 neutrons are present in Sr
Explanation:
Answer:
For ²⁴Mg
1. Proton number = 12
2. Neutron number = 12
For ⁸⁸Sr:
1. Proton number = 38
2. Neutron number = 50
Explanation:
For ²⁴Mg:
1. Determination of the number of proton.
The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.
Atomic number = 12
Proton number = Atomic number
Proton number = 12
2. Determination of the Neutron number.
Mass number = 24
Proton number = 12
Neutron number =?
Mass number = Proton + Neutron
24 = 12 + Neutron
Collect like terms
Neutron = 24 – 12
Neutron number = 12
For ⁸⁸Sr:
1. Determination of the number of proton.
The atomic number of ⁸⁸Sr is 38.
Atomic number = 38
Proton number = Atomic number
Proton number = 38
2. Determination of the Neutron number.
Mass number = 88
Proton number = 38
Neutron number =?
Mass number = Proton + Neutron
88 = 38 + Neutron
Collect like terms
Neutron = 88 – 38
Neutron number = 50
What is the minimum number of kiloJoules needed to change 40.0 grams of water at 100C to steam at the same temperature and pressure
Answer:
90.4Kg
Explanation:
The energy required= latent heat of vaporization
Latent heat of vaporization of water= 2260 KJ/Kg
Mass of water = 0.04 Kg
Heat required= 0.04Kg× 2260 KJ/Kg
Heat required= 90.4Kg
Answer: The minimum number of kilo Joules needed is 90.4KJ.
Explanation:
The energy required= latent heat of vaporization.
Latent heat of vaporization of water= 2260 KJ/Kg
Mass of water = 0.04 Kg
Heat required= 0.04Kg× 2260 KJ/Kg
Heat required= 90.4KJ.

K, Sc, Ca, Zn, Br
Sc, K, Br, Zn, Ca
OK, Ca, Sc, Zn, Br
O Br, Zn, Sc, Ca, K
Ca, Zn, Br, K, SC
Answer:
O, Ca, Zn, Br
Sc, K, Br,
Explanation:
The correct order of the chemical elements from highest to lowest electronegativity is: C. Br, Zn, Sc, Ca, K.
Electronegativity refers to a measure of the ability of an atom of a chemical element to attract any shared pair of electrons.
Generally, the electronegativity of a chemical element typically increases across the period from left to right.
In Chemistry, the electronegativity of some of the chemical element are:
Bromine (Br) = 2.96Calcium (Ca) = 1.0Zinc (Zn) = 1.65Potassium (k) = 0.82Scandium (Sc) = 1.36Hence, the order of the chemical elements from highest to lowest electronegativity is:
1. Bromine (Br) = 2.96
2. Zinc (Zn) = 1.65
3. Scandium (Sc) = 1.36
4. Calcium (Ca) = 1.0
5. Potassium (k) = 0.82

Please, I really need help. I don't know what to do...
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
How many atoms are present in 1.4 grams of aluminum?
Answer: 3.2x10^23
Explanation:
Start by finding the molar mass of aluminum.
Then turn grams into moles by dividing grams of substance by molar mass. 1.4g÷26.98g
Then multiply that by 6.022x10^23 atoms. 0.0519x6.022x10^23
You can use dimensional analysis to solve this type of problem.
