A single electron configuration can represent multiple atoms. The one below represents the following atoms with different charges. Determine what charge they need to match the electron configuration. 1s²2s²2p⁶3s²3p⁶4s²3d⁷
Answers
Answer:
To have the electronic configuration equal to 1s²2s²2p⁶3s²3p⁶4s²3d⁷, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.
Explanation:
The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.
The layers sub-levels are presented in the following order 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f14 5d¹º 6p⁶ 7s² 5f14 6d¹º 7p⁶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.
Accordingly, we can see that an atom that has the configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁷ has 27 electrons, like Cobalt.
Convert 49.3 grams of NaCl to moles of NaCl atoms
Answers
Answer:
0.845mol NaCl
Explanation:
NaCl has a molar mass of 58.44g/mol.
49.3g/58.44g/mol = 0.845mol
Answer:
0.844
Explanation:
if you divide 49.3 by 58.44 it gives you 0.84360027 which you then round up to 0.844. I know my answer is correct cause I just took the test

The frequency of the musical note F3 is 1.85 102 hertz. What is its period?
A 5.40 x 10-3seconds
B. 1.05 x 10-3 seconds
C. 3.09 x 10-3 seconds
D. 5.31 x 10-1 seconds
Answers
Answer: 0.0054 s
Explanation: There is an inverse relation between the frequency and the period of a wave (a sound wave in this case):
T=1/F
Where f = 1.85 (10)² H z
Hence : T = 1/1.85 (10)² H z T =0.0054s

A gas occupies a volume of 143 mL at 35.0 °C and .5 atm. What is the volume of the gas at standard temperature and pressure of 1 atm and 0°C.
A.0 mL
B.8.50 x 10-4 mL
C.63.4 mL
D.557.7 mL
Answers
P1V1/T1 = P2V2/T2
P1 = 0.5 atm
V1 = 143 mL
T1 = 35.0°C = 308 K
P2 = 1 atm
V2 = ?
T2 = 0°C = 273 K
Solve the equation for V2 and you get:
V2 = P1V1T2/T1P2 = (0.5 atm)(143 mL)(273 K) / (308 K)(1 atm) = 63.4 mL
C. 63.4 mL

PLEASE HELP ME !!!! which of these could be a possible molar mass of a compound with the empirical formula CH3?
Answers
Answer:
15.03 g/mol or any multiple of this, since this is the empirical formula
Explanation:
To find molar mass, look to the periodic table. C is carbon, which has a molar mass of 12.01 g/mol. H is hydrogen, which has a molar mass of 1.008 g/mol. You have one carbon and three hydrogens in this empirical formula, so 12.01 + 3(1.008) = 15.034 g/mol.The empirical formula is the lowest whole number ratio for the elements in a compound. Therefore the answer would be 15.03 g/mol or any multiple of this, since this is the amount for the empirical formula.
Find the mass of 1.59 mol of NH3
Answers
Answer:
27.03 grams
Explanation:
moles (n) = mass(m)/Molar mass(M)
moles = 1.59
mass = ?
N = 14, H = 1
M(NH3) = 14 + 3(1) = 17
Substitute the values into the equation:
nM = m
∴ m = 1.59 × 17 = 27.03

complete end balance the reaction :copper plus hydrobromic acid
Answers
Answer:
The correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2
Explanation:
Copper (Cu) and hydrobromic acid (HBr), which is a dissolved form of hydrogen bromide in the water, react and produce hydrogen dibromidocuprate (I) and hydrogen molecules.
The complete and balanced equation is -
2Cu + 4HBr → 2H[CuBr2] + H2
This reaction takes place in the medium of ester. Copper is in the suspension form in this reaction.
Thus, the correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2
