Draw a graph of how kinetic energy & temperature are related
(LOOK AT THE PICTURE ATTACHED)
Answers
Answer:
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

If 23.17 g of beryllium (Be) reacts with water at standard temperature and pressure,
how many liters of hydrogen (H2) are produced?
Answers
Volume of H2 produced = 57.6576 L
Further explanationGiven
23.17 g Be
Required
Volume of H2
Solution
Reaction
Be(s)+H2O(g)→BeO(s)+H2(g)
mol Be :
= 23.17 g : 9 g/mol
= 2.574
From the equation, mol H2 : mol Be = 1 : 1, so mol H2 = 2.574
Volume H2(assumed at STP, 1 mol=22.4 L) :
= 2.574 x 22.4 L
= 57.6576 L

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.

Which of the following are held together by nonpolar covalent bonds? PLEASE HELP
Answers
Answer:
The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
C. Atoms of chlorine (CI)
A covalent bond is created when the electrons from the two involved atoms are shared equally.The pair of electrons involved in this kind of bonding is referred to as the shared pair or bonding pair. Here the atoms of chlorine have non-polar covalent bonds. The correct option is C.
What are non-polar covalent bonds?A non-polar covalent connection is created when atoms with an equal amount of electrons share one another. The electronegativity of the two atoms is equivalent. When two atoms with similar electron affinities join together, like in the case of diatomic elements, it happens.
Non-polar covalent compounds are those in which there is no variation in electronegativity. In these compounds, the electronegativity does not change, preventing the motion of the bond pair's electrons in the direction of the linked atoms.
As a result, a molecule is non-polar and non-conducting since there is no bond or dipole moment between its atoms and no buildup of charges on the atoms.
Thus the correct option is C.

4. How many moles of H, would be
produced from 47 grams of H2SO4?
2A1 +3H,504 → Al2(SO4)3 +3H2
Answers
Answer:
0.48 moles of H₂ are produced.
Explanation:
Given data:
Number of moles of H₂ produced = ?
Mass of H₂SO₄ = 47 g
Solution:
Chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Number of moles of H₂SO₄ :
Number of moles = mass/molar mass
Number of moles = 47 g/ 98 g/mol
Number of moles = 0.48 mol
Now we will compare the moles of H₂SO₄ and H₂
H₂SO₄ : H₂
3 : 3
0.48 : 0.48
Thus, 0.48 moles of H₂ are produced.

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.
