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.

Does the size of the solute (sugar) affect the rate of dissolving?
Answer:
Yes
Explanation:
The rate at which a solute dissolves depends upon the size of the solute particles. Dissolving is a surface phenomenon since it depends on solvent molecules colliding with the outer surface of the solute.

1. How many moles of Boron is 1.25 x 1023 atoms of Boron? *
O 0.208 mol B
0 7.53 x 1046 mol B
O 1.35 x 1025 mol B
0 4.82 mol B
Answer:
0.208 mol B
Explanation:
There are 6.02 × 10^23 atoms in one mole of a substance, according to Avagadro's law.
According to this question, there are 1.25 x 10^23 atoms of Boron. This means that the number of moles in the Boron atom can be calculated thus:
number of moles (n) = number of boron atoms (nA) ÷ Avagadro's number
n = 1.25 x 10^23 ÷ 6.02 × 10^23
n = 0.2076 × 10^(23-23)
n = 0.208 × 10^0
n = 0.208 × 1
n = 0.208 moles of Boron

What two types of matter are closest in
density? How do you know?
ings.
Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Plz help me with these three please please !!!!!
Explanation:
Cations are positively charged ions with fewer electrons than protons. To partake in reaction, metals lose electrons to achieve a stable octet configuration. It has lost valence electrons and wold have a positive charge associated with it.
Potassium is a group 1 element. A metal.
Potassium has 1 valence electron so it loses the valence electron to form a stable octet.
A potassium ion has a positive charge and therefore cannot be an anion but is a cation.
The group number pretty much denotes the number of valence electrons.
Group 1 = 1
Group 2 = 2
Group 17 = 7
Group 18 = 8

What effect does doubling the concentration have on the rate?
A. doubles the rate
B. triples the rate
C. quadruples the rate
D. no effect on the rate
C. quadruples the rate
Further explanationGiven
The rate law :
R=k[A]²
Required
The rate
Solution
There are several factors that influence reaction kinetics :
1. Concentration 2. Surface area 3. Temperature 4. Catalyst 5. Pressure 6. StirringThe rate is proportional to the concentration.
If the concentration increased, the reaction rate will increase
The reaction is second-order overall(The exponent is 2)
The concentration of A is doubled, the reaction rate will increase :
r = k[A]² ⇒ r= k[2A]²⇒r=4k[A]²
The reaction rate will quadruple.

The mass of 5.60 Liter oxygen at 1.75 atm pressure and 250.0 K temperature is 24.0 gram.
What is ideal gas equation?
Ideal gas equation is a hypothesis which tells about the behavior of gas at standard condition and it is represented as:
PV = nRT, where
P = pressure = 1.75 atm
V = volume = 5.60 L
R = universal gas constant = 0.0821 L.atm /K.mol
T = temperature = 250 K
n is the moles of gas which will further define as:
n = W/M, where
W = required mass
M = molar mass
Now putting all the value in the above ideal gas equation and calculate for moles as:
n = (1.75)(5.60) / (0.0821)(250)
n = 0.751
Molar mass of oxygen is 32 g/mol and we calculate their required mass as:
W = 32 g/mol x 0.751 mol= 24.0 g
Hence, the required mass of oxygen is 24.0 g.

how many grams of PH3 will be produced if 6.0 l of H2 are used?
Mass of PH3= 6.086 g
Further explanationGiven
6.0 L of H2
Required
mass of PH3
Solution
Reaction
P4 + 6H2 → 4PH3
Assumed at STP ( 1 mol gas=22.4 L)
Mol of H2 for 6 L :
= 6 : 22.4 L
= 0.268
From the equation, mol PH3 :
= 4/6 x moles H2
= 4/6 x 0.268
= 0.179
Mass PH3 :
= 0.179 x 33,99758 g/mol
= 6.086 g
What is the total amount of heat energy, in
joules, absorbed by 25.0 grams of water when the
temperature of the water increases from 24.0°C to
36.0°C?
Answer:
0.84
Explanation:
total heat energy =mass ×specific heat capacity (4.2kJ)×temp change
mass=25g convert to kg to get 0.025
specific heat capacity is 4.2
temp change=36.0-24.0=8.0
q = mC∆T
m=25.0
c=24.0
ΔT=36.0
25.0 * 24.0 * 36.0 = 21,600 jules
The equation q = MC ∆ T, where m is the sample mass, c is the specific heat, and ΔT is the temperature change, can be used to determine the amount of heat acquired or lost by a sample (q).
How can you figure out how much energy was consumed?
This is simple to perform; to calculate the amount of heat absorbed, multiply the substance's heat capacity by its mass and the temperature change.
The specific heat capacity of a substance is the amount of energy needed to raise the temperature of 1 gram of that substance by 1 degree Celsius. With a value of 4.18 J/g/°C, water has one of the highest heat capacities.

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.
