At this point, helium is exerting 1270 torr of pressure against its container.
What is Boyle's Law?Boyle's Law, a cornerstone of chemistry, describes the behavior of a gas sustained at a constant temperature. Robert A. Boyle discovered this law in 1662: at a certain temperature, the volume of a gas is inversely proportional to the pressure it exerts. To put it another way, if a gas is driven into a closed place, it will condense to fit the area but raise the pressure on the container.
Boyle's law, which is arguably a clearer way to put it, is the relationship between pressure and volume. Mathematically, Boyle's law can be written as pV=k, where p stands for the pressure, volume, and mass of the gas and k is a constant.
The solution is straightforward when temperature and moles are constant,
P₁V₁ = P₂V₂
Given,
P₁ = 760 torr
P₂ = ?
V₁ = 5.00 I
V₂ = 3.00 I
(760)(5.00) = (3.00)(P₂),
P2 = 1270 torr.

what is the ph of a buffer in which the concentration of benzoic acid, c6h5cooh, is 0.075 m and the concentration of sodium benzoate, nac6h5coo, is 0.050 m ?
The answer is 4.02.
Benzoic acid is a weak acid and sodium hydroxide is a strong base. Benzoic acid and sodium hydroxide react to form sodium acetate and water to form a buffer solution. pH can be measured by measuring the voltage developed between two special electrodes immersed in a liquid solution.
Special glass electrodes are called measuring electrodes. It neutralizes benzoic acid to produce benzoate ions, which enter the water layer, leaving two other organic compounds in the ether. Similarly, nitroaniline does not dissolve under neutral or basic conditions but dissolves in acidic solutions. This clearly shows that formic acid is a stronger acid than benzoic acid.

increased co2 in the atmosphere since the industrial revolution has resulted in lower surface ocean ph of about ph units.
Since the start of the industrial revolution more than 200 years ago, human activity has led to an increase in the atmospheric concentration of carbon dioxide (CO2). The pH of the ocean's surface waters has decreased by 0.1 pH units throughout this time.
As a result of the rise in atmospheric CO2 concentrations, the pH of the ocean surface has decreased over the industrial age, falling from 8.2 to below 8.1. This drop is accompanied by a 30% increase in oceanic acidity.It first creates carbonic acid. The carbonic acid then "dissociates," or separates, into bicarbonate ions and hydrogen ions. Ocean acidification is caused by an increase in hydrogen ion concentration and a decrease in carbonate ions as a result of increasing CO2 absorption.What is the meaning of Industrial Revolution ?A significant and swift transition in an economy (as in late-18th-century England) signaled by the widespread adoption of power-driven machinery or by a significant shift in the prevalent forms and applications of such machinery.

Which statement correctly describes the bonding in metals? * (1 Point)
A) lattice of negative ions in a sea of electrons
B) lattice of positive ions in a sea of electrons
C) lattice of neutral atoms with delocalised electrons.
D) lattice of negative ions with delocalised electrons.
Answer:
C) lattice of neutral atoms with delocalised electrons
Explanation:
Fact 1: metals are elements and therefore they contain atoms that are electrically neutral
Fact 2: in all atoms, the electrons are delocalised/ are free moving electrons (as the electrons serve their purpose in different forms depending whether you look at it the chemistry way or physics way)
metals are solid and hence they have a lattice structure
(tho at my school we focus on giant ionic lattice structure when explaining based on ionic compounds so i can't guarantee that 'giant ionic lattice structure' and 'lattice structure' are the same, hence i just stick with lattice structure for this explanation ^^)
explanation for other options:
they said negative/positive ions which is not true since atoms are electrically neutral
only when the atoms undergo chemical reactions will they be charged
what molecule is the final electron acceptor after the electron has moved through the electron transport chain?
Oxygen is the final electron acceptor after the electron has moved through the electron transport chain.
In the electron transport chain, electrons are moved from protein to protein. The transport chain's succeeding proteins can each take an electron with a lower energy. Energy is released as electrons go from a high-energy state to a low-energy state. Protons are pumped across the membrane using this energy to create a gradient.
Oxygen serves as the ultimate electron acceptor (O2). Since oxygen has a strong affinity for electrons and a high electronegativity.

molecular formula: c57h110o6. what is the minimum amount of oxygen required, in g, for complete combustion?
The minimum amount of oxygen required, in g, for complete combustion of C₅₇H₁₁₀O₆ will be 1304 g
Molecular formula = C₅₇H₁₁₀O₆
The amount is not given so we take it as 1 mol
The minimum amount of oxygen required for combustion = ?
First, we will write the chemical equation
C₅₇H₁₁₀O₆ + O₂ = CO₂ + H₂O
Balance the chemical equation
2C₅₇H₁₁₀O₆ + 163O₂ = 114CO₂ + 110H₂O
The molar ratio of C₅₇H₁₁₀O₆ to oxygen is 2 : 163
As we have 1 mol C₅₇H₁₁₀O₆; 163 / 2 = 81.5 mol
number of moles of O₂ required = 81.5 mol
Covert the number of moles to grams
grams = number of moles × molar mass

D. It takes place in plant and animal cells and involves chemical reactions with oxygen to release stored energy.
Answer:

Explanation:
every chemical reaction proceeds through a high-energy unstable species as reactants are converted to products and bonds are in the process of being formed and/or broken. this unstable species is called a(n) complex or state.
The unstable species is called as transition state.
Transition state in a chemical reaction is a point in the chemical reaction with highest potential or highest energy. This state is said to be the most unstable stage of any chemical reaction and this unstable stage exists between the substrate and the products.
When any chemical reaction takes place the energy of the reaction or the potential of the reaction gradually starts increasing as new bonds are about to form and the old bonds are ready to break. Once the reaction reaches a highest potential point we can see that at this point partial bond braking and partial bond is happening, this is called as the transition state.
As this is the unstable state the reaction starts to loose energy as the product is formed.

The molarity of the solution is 0.95M and the concentration of the Silver cation and the concentration of the acetate anion is also 0.95M.
The mass of the Silver Acetate dissolved in the water of volume 125 ml is 20 grams.
We can write the reaction of the dissolution of the Silver Acetate into water as,
CH₃COOAg = CH₃COO- + Ag+
It means that the concentration of the Silver cation and the Acetate anion is equal in the solution of water.
It means that the molarity of the solution will be equal to the concentration of the Silver cation and the concentration of the Acetate and iron in the water.
We know that the molarity of the solution is defined as the number of moles of solute per unit volume of the solution in litres.
Moles = mass/molar mass
Molar mass of the Silver Acetate is 166.91 g/mol.
The mass of silver Acetate dissolved is 20 grams.
So, the moles of silver Acetate is,
Moles = 20/166.91
Molarity of the solution,
Molarity = moles of silver acetate/volume of water
Molarity = 20/166.91 × 1000/125

The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.
Calculation:-
final conc=m1v1+m2v2/(v1+v2)
final conc=209 × 0.71+407 ×0.41/(407+209)
final conc = 0.512 M
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.
