You have been given a choice of four elements; Lithium, Magnesium, Sulfur, and Bromine. You must decide which two elements would form a compound that has one atom of the metallic atom and two of the non-metallic atom in the final neutral compound. Which choice lists the two atoms with the correct formula for the compound?
A.
Magnesium and Sulfur; MgS2
B.
Lithium and Bromine; LiBr2
C.
Lithium and Sulfur; Li2S
D.
Magnesium and Bromine; MgBr2
The compound formed that has been neutral has been Magnesium and bromine. Thus, option D is correct.
The periodic table has been the arrangement of the elements with increasing atomic number and similarity in the reactivity.
The metals in the periodic table are elements that has been able to accept electrons, and nonmetals are the elements in the table that loses electrons to attain the stable noble gas configuration.
Formation of a neutral compoundThe metal and nonmetal form the neutral compound when there has been the formation of stable compound with the complete configuration.
The magnesium and lithium has been metals, while sulfur and bromine are nonmetals. Bromine has been the element of group 17. It has been able to gain an electron. Sulfur has been the nonmetal and required 2 electrons to complete its octet.
Lithium has been the metal with one valence electron, and magnesium with 2 valence electrons.
The neutral compound to be formed has been consisted of one metal with 2 valence electrons, and 2 nonmetals with 1 valence electrons.
Thus, the compound formed that has been neutral has been Magnesium and bromine. Thus, option D is correct.

How many moles are in 6.777 x 1023 atoms of CO2. Watch your significant figures. Question 2 options: 1 atoms CO2 1.125 moles CO2 1.13 moles 1.13 atoms CO2
Answer:
1.13moles
Explanation:
Given parameters:
Number of atoms = 6.777 x 10²³ atoms
Unknown:
Number of moles = ?
Solution:
A mole of a substance contains the avogadro's number of particles
6.02 x 10²³ particles = 1 mole
6.777 x 10²³ atoms will contain [tex]\frac{ 6.777 x 10^{23} }{6.02 x 10^{23} }[/tex] = 1.13moles

How many moles of NaCl are in 2.35 liters of a 4.67 M solution?
There are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles of a substance can be calculated by multiplying the molarity by the volume. That is;no. of moles = volume × molarity
According to this question, there are 2.35 liters of a 4.67 M solution. The number of moles is calculated as follows:no of moles = 2.35L × 4.67M
no of moles = 10.97mol
Therefore, there are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.

Cuantos gramos de nitrato de potasio (KNO3) son necesarias para preparar 800ml de solucion al 12 % m/v
Answer:
96 g
Explanation:
Tomando en cuenta que estamos hablando de una solución de Nitrato de potasio cuya concentración es 12% m/V, debemos entonces usar la expresión de %m/V:
%m/V = msto / Vsol * 100 (1)
De esta expresión, debemos despejar la masa de soluto (msto) que es precisamente el valor que estamos buscando. Al hacer el despeje tenemos:
msto = %m/V * Vsol / 100 (2)
Ahora solo nos queda sustituir los valores dados y resolver:
msto = 12 * 800 / 100
msto = 96 g de KNO₃Espero te sirva.
