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
Answers
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.

The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.
What do you mean by mole ?The term mole is defined as the amount of substance of a system which contains as many elementary entities.
1 mole is equal to 6.023 × 10 ²³ molecules.
One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.
The mole concept can be used to convert between mass and number of particles.
A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.

Find the mass of 5.60 L O2 at 1.75 atm and 250.0 K
Answers
Answer:
Moles O2 = pV/RT = 2.75 x 5.60 / 0.08206 x 250=0.751
mass = 32 g/mol x 0.751 mol= 24.0 g
Explanation:
Hope it help
Mark me as brainliest
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.

As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.

C)The Earth's axis moves back and forth, resulting in different seasons
D)The Earth moves in an elliptical orbit around the sun
Answers
Answer:
D)The Earth moves in an elliptical orbit around the sun
The statement earth moves in an elliptical orbit around the sun best describes the movement of earth around the sun.
What is earth?Earth is the third planet of the solar system and the only astronomical object known to support life.
What is an elliptical orbit?When an object moves around another object in an oval shaped path, it is known to be revolving in an elliptical orbit.The orbit is elliptical because of Newton's law of gravity.The planets in the solar system orbit the sun in elliptical orbits. Many satellites orbit the Earth in elliptical orbits as does the moon.The movement of the earth around the sun in a fixed path or orbit is called Revolution. The axis of the earth which is an imaginary line, makes an angle of 66½° with its orbital plane.

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
Answers
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 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?
Answers
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.
