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.

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.

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.

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.
