The maximum number of Percocet tablets a patient can take daily, while staying within the recommended acetaminophen dose of 3.9g, is 12 tablets.
To determine the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of 3.9g of acetaminophen, we need to perform a unit conversion.
1. Convert 3.9g to mg (since the amount of acetaminophen per tablet is given in mg): 3.9g = 3900mg
2. Calculate the number of Percocet tablets based on the amount of acetaminophen per tablet: Each Percocet tablet contains 325mg of acetaminophen.
3. Divide the maximum allowable dose of acetaminophen (3900mg) by the amount of acetaminophen per tablet (325mg) to find the maximum number of tablets: 3900mg / 325mg = 12 tablets
Therefore, the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of acetaminophen (3.9g) is 12 tablets.

Group 1 elements have an average electronegativity of 0.84 (not including hydrogen). Group 17 elements have an average electronegativity of 2.99. These two groups often form bonds. Given this information, which kind of bond will they likely form (ionic or covalent), and what evidence supports your claim? If it is ionic, then include which group gives up its electron to the other group. In three to five sentences, explain your reasoning
The elements of group 1 makes ionic bond with the elements of group 7 due to high difference of electronegativity values.
Type of bond between group 1 and 7The elements of first group lose its one outermost electrons while on the other hand, the elements of seven group needs one electron so they gain that one electron so they make an ionic bond with each other.
So we can conclude that the elements of group 1 makes ionic bond with the elements of group 7 because of the high difference of electronegativity values.

What different families present in the periodic table
In the periodic table, there are different ways to categorize the element families. One way is to categorize them as 5 element families, Alkali metals, Alkaline earth metals, Transition metals, Halogens, and Noble gases. There is another method of categorization that recognizes nine element families, Alkali Metals: Group 1 (IA) - 1 valence electron, Alkaline Earth Metals: Group 2 (IIA) - 2 valence electrons, Transition Metals: Groups 3-12 - d and f block metals have 2 valence electrons, Boron Group or Earth Metals: Group 13 (IIIA) - 3 valence electrons, Carbon Group or Tetrels: - Group 14 (IVA) - 4 valence electrons, Nitrogen Group or Pnictogens: - Group 15 (VA) - 5 valence electrons, Oxygen Group or Chalcogens: - Group 16 (VIA) - 6 valence electrons,Halogens: - Group 17 (VIIA) - 7 valence electrons, Noble Gases: - Group 18 (VIIIA) - 8 valence electrons.
The columns of the periodic table mark groups or families, in which there are three systems that have been used to number families and groups. The first one is the older IUPAC system that used Roman numerals together with letters to distinguish between the left and right sides of the periodic table. Secondly is the CAS system that used letters to differentiate main group and transition elements. Lastly is the modern IUPAC system that uses Arabic numbers 1-18, simply numbering the columns of the periodic table from left to right. Many periodic tables use both Roman and Arabic numbers, but the Arabic numbering system is the most widely accepted today.

Alkali Metals:
1 valence electronSoft metallic solidsShiny, lustrousHigh thermal and electrical conductivityLow densities, increasing with atomic massRelatively low melting points, decreasing with atomic massVigorous exothermic reaction with water to produce hydrogen gas and an alkali metal hydroxide solutionIonize to lose their electron, so the ion has a +1 chargeSome examples include Sodium and potassium, and under the right conditions of temperature and pressure, hydrogen can be an alkali metal.Next is Alkaline Earth Metals or Group 2 Family of Elements

explain how the atoms are held together by tge covalent bond in a molecule of hydrogen?
Answer:
A hydrogen molecule forms from two hydrogen atoms, each with one electron in a 1 s orbital. The two hydrogen atoms are attracted to the same pair of electrons in the covalent bond. The bond is represented either as a pair of “dots” or as a solid line. Each hydrogen atom acquires a helium-like electron configuration. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units. The hydrogen molecule is the simplest substance having a covalent bond.

In the given question, 1.3kg is the mass of [tex]\rm O_2[/tex] that will react with 400g of [tex]\rm C_4H_{10}[/tex] and 34.4 moles of [tex]\rm H_2O[/tex] are formed in the reaction.
Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol).
a) To determine the mass of [tex]\rm O_2[/tex]that will react with 400 g of [tex]\rm C_4H_{10}[/tex], we need to use stoichiometry to determine the mole ratio of [tex]\rm C_4H_{10}[/tex] to [tex]\rm O_2[/tex]in the balanced chemical equation.
[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]
From the equation, we can see that 2moles of [tex]\rm C_4H_{10}[/tex] react with 13 moles of [tex]\rm O_2[/tex]. Therefore, we can set up a proportion:
2 mol / 13 mol [tex]\rm O_2[/tex]= 400 g [tex]\rm C_4H_{10}[/tex] / x g [tex]\rm O_2[/tex]
where x is the mass of [tex]\rm O_2[/tex] that will react with 400 g of [tex]\rm C_4H_{10}[/tex] .
Solving for x, we get:
x = (13 mol [tex]\rm O_2[/tex] [tex]\times[/tex] 400 g [tex]\rm C_4H_{10}[/tex] ) / (2 mol [tex]\rm C_4H_{10}[/tex] )
x = 1.3 kg [tex]\rm O_2[/tex]
b) To determine the number of moles of water formed in part a), we need to use stoichiometry again to determine the mole ratio of [tex]\rm C_4H_{10}[/tex] to [tex]\rm H_2O[/tex] in the balanced chemical equation.
[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]
From the equation, we can see that 2moles of [tex]\rm C_4H_{10}[/tex] react with 10 moles of [tex]\rm H_2O[/tex] . Therefore, we can set up another proportion:
2 mol [tex]\rm C_4H_{10}[/tex] / 10 mol [tex]\rm H_2O[/tex] = 400 g [tex]\rm C_4H_{10}[/tex] / x mol [tex]\rm H_2O[/tex]
where x is the number of moles of [tex]\rm H_2O[/tex] formed.
First, we need to convert 400 g of [tex]\rm C_4H_{10}[/tex] to moles:
400 g [tex]\rm C_4H_{10}[/tex] [tex]\times[/tex] (1 mol [tex]\rm C_4H_{10}[/tex] / 58.12 g [tex]\rm C_4H_{10}[/tex] ) = 6.88 mol [tex]\rm C_4H_{10}[/tex]
Now we can solve for x:
2 mol [tex]\rm C_4H_{10}[/tex] / 10 mol [tex]\rm H_2O[/tex] = 6.88 mol [tex]\rm C_4H_{10}[/tex] / x mol [tex]\rm H_2O[/tex]
x = (10 mol [tex]\rm H_2O[/tex] [tex]\times[/tex] 6.88 mol [tex]\rm C_4H_{10}[/tex]) / (2 mol [tex]\rm C_4H_{10}[/tex] )
x = 34.4 mol [tex]\rm H_2O[/tex]
Therefore, 1.3 kg of [tex]\rm O_2[/tex] will react with 400 g of [tex]\rm C_4H_{10}[/tex] .34.4 moles of water are formed when 400 g of [tex]\rm C_4H_{10}[/tex] .
