The final volume of the gas that was heated from -25.0 °C to standard temperature is 2.2L.
How to calculate volume?The volume of a given gas can be calculated using the Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperatureV1 = 2LV2 = ?T1 = -25°C + 273 = 248KT2 = 273K2/248 = V2/273
273 × 2 = 248V2
546 = 248V2
V2 = 546/248
V2 = 2.2L
Therefore, the final volume of the gas that was heated from -25.0 °C to standard temperature is 2.2L

Na2CO3 + H2O.
a. If the average human body discharges 925,0 g CO, per day, how many moles of NaOH are
needed each day for each person in the spacecraft?
b. How many moles of each product are formed?
Answers
For a (unbalanced) reaction: NaOH +CO2-Na2CO3 + H2O, the moles of NaOH and moles of each product are formed are mathematically given as
a) Moles of NaOH =44.05
b) Moles of Na2CO3=21.0
Moles of H2O= 21.0What is the moles of NaOH and what moles of each product are formed?
Generally, the equation for the Chemical reaction is mathematically given as
2 NaOH(aq)+ CO2(g)------> Na2CO3(aq)+ H2O(l)
Therefore
Moles of CO2= 925/44
Moles of CO2=21.0
Hence
Moles of NaOH = 2 x Moles of CO2
Moles of NaOH = 2x925/44
Moles of NaOH =44.05
In conclusion
Moles of Na2CO3 925/44
Moles of Na2CO3=21.0

1. If the water is not completely removed from the salt during the heating process will the reported water-to-salt mole ratio (X) be high or low? Explain
Answers
Answer:
The water in the hydrate (referred to as "water of hydration") can be removed by heating the hydrate. When all hydrating water is removed, the material is said to be anhydrous and is referred to as an anhydrate.
Explanation:
If the water is not completely removed from salt during heating process it will result in higher mole ratio of water to salt as mass of water will also be accounted while calculating mole ratio.
What is salt?Salt is defined as a chemical compound which is ionic in nature and consists of cation and an anion.It has no net electrical charge as the charges are completely neutralized in case of salts.
They are classified as acidic, basic or neutral salts depending on the ions they produce on dissolution.They have wide variety of colors depending on the elements from which they are formed and have five basic tastes.Salts are usually odorless except a few exceptions . They are highly soluble in water and are insulators in the solid state, to make them conductive they need to be melted or dissolved.

how does the melting point of a substance indicate the strength of its intermolecular force of attraction
Answers
Answer:
The molecules are held together by intermolecular force of attraction. More the force the fusion takes after some time only that means the melting point is high. So molecules with greater molecular forces have high melting point and less molecular forces have low melting point.
Answer:
On heating a solid, the kinetic energy of the particle increases. The particle start vibrating with greater speed. The energy supplies by heat overcomes the force of attraction between the particles.
If this force of attraction is more, then more heat energy will be necessary to overcome this force. So, the melting point of the solid will be higher.

B.

C. 760.0 mm of Hg
D. 570.0 mm of Hg
Answers
Answer:
A
Explanation:
.75 + .25 + 1.25 = 2.25 atm
1 atm is 760 mm hg
2.25 * 760 = 1710 mm HG
Answer:
[tex]\huge\boxed{\sf 2.25\ atm = 1710\ mm\ of\ Hg}[/tex]
Explanation:
Partial pressure of gas A = 0.75 atm
Partial pressure of gas B = 0.25 atm
Partial pressure of gas C = 1.25 atm
Total partial pressure = 0.75 atm + 0.25 atm + 1.25 atm
= 2.25 atm
We know that:
1 atm = 760 mm of Hg
Multiply 2.25 to both sides
2.25 atm = 760 × 2.25 mm of Hg
2.25 atm = 1710 mm of Hg

Answer:
By mixing two solutions of differing pH values, the final pH of the mixed solution is going to be a function of the pH-, or the hydrogen ion (H+), of the lower pH solution, and the final volume. The hydrogen ion(H+) of the higher pH solution has little to no effect in the final pH value.

Does combining the glue and water create a physical or chemical change?
Answers
The combination of glue and water creates a physical change rather than a chemical change.
Physical and chemical changesPhysical changes are changes to the physical properties of materials and are usually reversible.
Chemical changes, on the other hand, are changes to the chemical properties of materials and are usually irreversible.
Mixing water with glue will only result in the glue being diluted with water and creates no chemical reaction. The glue can be recovered by distilling off the water.
Thus, mixing glues with water is only a physical change as the chemical properties of the glue remain intact.
