how many mols of Ti is 3.15 * 10^23 atoms of Titanium
Answer: There are 0.523 moles of Titanium in [tex]3.15\times 10^{23}[/tex] atoms of Titanium
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}[/tex]
[tex]\text{Number of moles of Titanium}=\frac{3.15\times 10^{23}}{6.023\times 10^{23}}=0.523moles[/tex]

An aluminum pan and a copper pan have the same mass and are heated to the same temperature. Which will feel hotter?
Answer:
The copper pan!
Explanation:
Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one. Valence electrons move about freely.

A cylinder, with a piston pressing down with a constant pressure, is filled with 1.90 moles of a gas (n1),
and its volume is 40.0 L (V1). If 0.400 mole of gas leak out, and the pressure and temperature remain the
same, what is the final volume of the gas inside the cylinder?
Answer:
31.58 L
Explanation:
From the question given above, the following data were obtained:
Initial mole (n₁) of gas = 1.90 moles
Initial volume (V₁) = 40 L
Final mole (n₂) = 1.90 – 0.40 = 1.5 moles
Final volume (V₂) =.?
The final volume of the gas can be obtained as follow;
V₁ / n₁ = V₂ / n₂
40 / 1.9 = V₂ / 1.5
Cross multiply
1.9 × V₂ = 40 × 1.5
1.9 × V₂ = 60
Divide both side by 1.9
V₂ = 60 / 1.9
V₂ = 31.58 L
Thus, the final volume of the gas is 31.58 L

Which of the following best describes an Arrhenius acid-base reaction?
O A. Acid + base = H+ + OH-
B. Acid + base = salt + water
C. Acid + base = conjugate base + conjugate acid
D. Acid + base =
H20
Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.

How do I balance coefficient equations
Answer:
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
Answer: When you balance a chemical equation, you change coefficients. You never change subscripts. A coefficient is a whole number multiplier. To balance a chemical equation, you add these whole number multipliers (coefficients) to make sure that there are the same number of atoms on each side of the arrow.

before phase change: molecules move around each other 15. The medicine in the diagram above has molecules that are moving around each other. The doctor needs to slow down the molecules enough to cause a phase change. How will she do this, and how will this affect the medicine? I She transfers energy ... a into the medicine until it is a liquid. b) into the medicine until it is a gas. C out of the medicine until it is a solid. d out of the medicine until it is a liquid. LE 1 21 Illuminate Education, Inc.
Answer:
She transfers energy out of the medicine until it is solid. So the answer would be C.
Explanation:
According to the forces of attraction , molecules can be slowed down by moving out of the medicine until it is a solid , it will decrease the rate of absorption of medicine.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

B. partial negative charge on the oxygen atom because it pulls electrons from the hydrogen atoms
C. partial positive charge on the oxygen atom because it pulls electrons from the hydrogen atoms
D. partial positive charge on the oxygen atom because its electrons are pulled toward the hydrogen atoms
The answer is B
Answer:
B. partial negative charge on the oxygen atom because it pulls electrons from the hydrogen atoms
Explanation:
Oxygen has a charge of 6 so they need to pull 2 electrons from hydrogen, which creates a partial negative charge.

A buffer solution contains 0.345 M acetic acid and 0.377 M sodium acetate . If 0.0613 moles of potassium hydroxide are added to 250 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume does not change upon adding potassium hydroxide. )
Answer:
pH = 5.54
Explanation:
The pH of a buffer solution is given by the Henderson-Hasselbach (H-H) equation:
pH = pKa + log[tex]\frac{[CH_3COO^-]}{[CH_3COOH]}[/tex]For acetic acid, pKa = 4.75.
We calculate the original number of moles for acetic acid and acetate, using the given concentrations and volume:
CH₃COO⁻ ⇒ 0.377 M * 0.250 L = 0.0942 mol CH₃COO⁻ CH₃COOH ⇒ 0.345 M * 0.250 L = 0.0862 mol CH₃COOHThe number of CH₃COO⁻ moles will increase with the added moles of KOH while the number of CH₃COOH moles will decrease by the same amount.
Now we use the H-H equation to calculate the new pH, by using the new concentrations:
pH = 4.75 + log[tex]\frac{(0.0942+0.0613)mol/0.250L}{(0.0862-0.0613)mol/0.250L}[/tex] = 5.54
