A)The Earth is closer to the sun in Summer than in Winter.
B)The Earth moves in a circular pattern around the Moon
C)The Earth's axis moves back and forth, resulting in different seasons
D)The Earth moves in an elliptical orbit around the sun
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.
Hence, option D is the correct answer.

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

Find the mass of 5.60 L O2 at 1.75 atm and 250.0 K
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:

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.

B. contain the same number of molecules
C. contain one molecule each
D. have the same mass
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.
Thus, option A is correct.

what are the steps to naming simple ionic compounds
Answer:
To name an ionic compound, you simply need to find the names of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.
Explanation:
Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion.
In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?
Answer:
24.06 g of CO₂
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> 2H₂O + CO₂
Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.
Thus, 24.06 g of CO₂ were produced from the reaction.

Answer:
20 g of copper (II) oxide, CuO
Explanation:
The balanced equation for the reaction is given below:
CuO + 2HCl —> CuCl₂ + H₂O
From the balanced equation above,
1 mole of CuO reacted to produce 1 mole of CuCl₂.
Next, we shall determine the number of mole of CuO needed to produce 0.25 mole of CuCl₂. This can be obtained as follow:
From the balanced equation above,
1 mole of CuO reacted to produce 1 mole of CuCl₂.
Therefore, 0.25 mole of CuO will also react to produce 0.25 mole of CuCl₂.
Finally, we shall determine the mass of 0.25 mole of CuO. This can be obtained as follow:
Mole of CuO = 0.25 mole
Molar mass of CuO = 64 + 16
= 80 g/mol
Mass of CuO =?
Mole = mass /Molar mass
0.25 = mass of CuO /80
Cross multiply
Mass of CuO = 0.25 × 80
Mass of CuO = 20 g
Therefore, 20 g of copper (II) oxide, CuO is needed for the reaction.
