Answer: the aspirin also contains a buffering agent—usually MgO—that regulates the acidity of the aspirin to minimize its acidic side effects.
Explanation:
Because the acid residences of aspirin may be complex, many aspirin manufacturers provide a "buffered aspirin" form of the drug. In these cases, the aspirin additionally includes a buffering agent-normally MgO-that regulates the acidity of the aspirin to minimize its acidic aspect consequences.
Why may a buffer be added to aspirin?Buffering agents are utilized in tablet formulations to grow the dissolution and absorption of vulnerable acid pills together with salicylic acid, aspirin, and p-aminosalicylic acid as well as to lower gastric infection of lively ingredients.
Why is buffered aspirin not a buffer?So-called "buffered aspirin" isn't surely a buffer, because it does no longer face up to acids and bases. it's miles sincerely aspirin mixed with a primary compound, consisting of magnesium carbonate or aluminum hydroxide, which neutralizes some belly acid.

Explanation:
All atoms of the same element:
have the same number of electrons
have the same number of protons
have the same number of atoms
have the same number of neutrons
Answer:
have the same number of protons
Explanation:
Atoms of the same element will always have the same number of protons.
Protons are the positively charged particles in an atom which are located in the nucleus.
To recognize an atom, the number of protons is used. The number of protons is the atomic number.On the periodic table, atoms are arranged based on the number of protons.How do I explain this? I'm a little stuck. :/
Answer:
Not balance.
Explanation:
Chemical equation:
K + Cl₂ → KCl
The given equation is not balance because there are one potassium and two chlorine atoms on left side of equation while on right side there are one potassium and one chlorine atom present.
Balance chemical equation:
2K + Cl₂ → 2KCl
the equation is balance now because there are two potassium and two chlorine atoms on left side of equation and two potassium and two chlorine atoms are also present on right side.

Branches are thrown into a wood chipper and mulch is created. Chemical change or physical change?
Definitely, a physical change.
What are chemical and physical changes?A chemical change is a type of change involving the chemical composition of substances. The chemical composition changes completely and lost its old identity.
Chemical changes are unlike physical changes. The latter involves changes to the physical characteristics of substances. The changes do not get to the chemical level.
Thus, chemical changes are ordinarily not reversible but physical changes can be reversed.
When branches are thrown into a wood chipper and mulch is created, a physical change has taken place because the branches can still be recovered from the mulch.
A mulch is just a material layer placed on soils to conserve moisture.

what is the half life of the element in the picture
HELP BRAINLIEST
Answer:
6 days
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 100 mg
Amount remaining (N) = 6. 25 mg
Time (t) = 24 days
Half life (t½) =?
Next, we shall determine the decay constant. This can be obtained as follow:
Original amount (N₀) = 100 mg
Amount remaining (N) = 6. 25 mg
Time (t) = 24 days
Decay constant (K) =?
Log (N₀/N) = kt / 2.303
Log (100/6.25) = k × 24 / 2.303
Log 16 = k × 24 / 2.303
1.2041 = k × 24 / 2.303
Cross multiply
k × 24 = 1.2041 × 2.303
Divide both side by 24
K = (1.2041 × 2.303) / 24
K = 0.1155 /day
Finally, we shall determine the half-life of the isotope as follow:
Decay constant (K) = 0.1155 /day
Half life (t½) =?
t½ = 0.693 / K
t½ = 0.693 / 0.1155
t½ = 6 days
Therefore, the half-life of the isotope is 6 days
Before an electrocardiogram is recorded for a cardiac patient, the ECG leads are usually coated with a moist paste containing sodium chloride. What property of an ionic substance such as NaCl is being made use of
Answer:
The property of the ionic substance utilized is its electrical conductivity
Explanation:
Ionic substances are substances which are composed of electrically charged particles called ions. Sodium chloride, NaCl is ionic substance which is composed of sodium ions, Na⁺ and chloride ions, Cl⁻. These ions are usually held in position in the solid form of these substances. However, in aqueous or molten forms, these ions are free to move about and thus conduct electrical charges around.
In an electrocardiogram, the ECG leads are usually coated with a moist paste containing sodium chloride in order to increase the electrical conductivity between the patient's skin and the electrodes because the sodium chloride will dissociate into chloride and sodium ions and are ths, able to conduct electricity.

Explain the difference between Carbon-12 and Carbon-14. Which version Carbon do you believe is the most stable? Why? What information could help you confirm your prediction?
Answer:
Carbon has three isotopes those are carbon- 12 , carbon - 13 , carbon-14 among these only C-12 and C-13 are stable while C-14 is radioactive.
C-12 has 6 protons and 6 neutrons , C-14 has 6 protons and 8 neutrons. Atoms with equal number of protons and electrons are generally stable however C-12 and C-14 have 6 electrons but due to excess neutrons present in C-14 makes it undergo radioactivity therefore it is unstable.

How many moles are contained in 5.0 g of SO2:
Hey there!
Molar mass SO₂ = 64.066 g/mol
Therefore:
1 mole SO₂ -------------------- 64.066 g
(moles SO₂ ) ??---------------- 5.0 g
( moles SO₂) = 5.0 * 1 / 64.066
(moles SO₂) = 5.0 / 64.066
moles = 0.0780 moles of SO₂

What is the average isotope mass?
Answer:
the atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope
Explanation:
Average atomic mass = f1M1 + f2M2 + … + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.

Which of the following is TRUE about Nuclear Fusion? A) it causes atoms to separate
B) it is used to produce energy in nuclear power plants C) it is the same way stars and our sun produce energy
Answer:
B)It is used to produce energy
The nuclear fusion reaction is also called thermonuclear reaction. The true statement is it is the same way stars and our sun produce energy. The correct option is C.
What is nuclear fusion?The process in which two lighter nuclei fuse together to form a heavier nucleus with the simultaneous release of a huge amount of energy is defined as the nuclear fusion.
In nuclear fusion some mass is lost and it is converted into energy in accordance with the Einstein's equation, E = mc². This huge amount of energy is released.
The fusion reactions are common in the interior of stars. The energy of our sun is believed to arise from a number of complex fusion steps. This reaction take place only at very high temperatures. The hydrogen bomb also work on the basis of fusion.
Thus the correct option is C.
