Answer:
276 mL
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
V1 = 225mL
V2 = ?
T1 = 23°C = 23 + 273 = 296K
T2 = 90°C = 90 + 273 = 363K
Using V1/T1 = V2/T2
225/296 = V2/363
Cross multiply
296 × V2 = 363 × 225
296V2 = 81675
V2 = 81675/296
V2 = 275.9
V2 = 276 mL
How many moles of calcium oxide are formed when 3 moles of calcium react with oxygen?
Answer:
3 moles of Calcium Oxide are formed
Explanation:
Based on the reaction of Calcium Ca, with oxygen, O₂, to produce calcium oxide, CaO is:
2Ca + O₂ → 2CaO
where 2 moles of calcium produce 2 moles of Calcium oxide.
That means, if 3 moles of Ca react in presence of oxygen:
3 moles of calcium oxide are formed

what can you infer about aspirin’s ester group?
A. It provides aspirin’s pain-killing ability.
B. It makes the compound more digestible.
C. It reduces fevers.
It's B
Answer:
Option B, aspirin’s ester group provides greater digestibility to aspirin
Explanation:
Aspirin ester group has three parts
carboxylic acid functional group (R-COOH) ester functional group (R-O-CO-R') aromatic group (benzene ring)Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -
aspirin
(acetylsalicylic acid) + water → salicylic acid + acetic acid
(ethanoic acid)
Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

What is the difference between an imprint and an impression?
Answer:
As nouns the difference between impression and imprint
is that impression is the indentation or depression made by the pressure of one object on or into another while imprint is an impression; the mark left behind by printing something.
The term imprint is defined as to mark by or as if by pressure and the term impression is defined as the effect produced by impressing.
What is the difference between an imprint and an impression?The difference between an imprint and an impression is that the imprint is the mark left behind when anything is printed, whereas the impression is the indentation or depression caused by the pressure of one object against or into another.
While a shoe won't make an impression in loose sand, it will on a hard surface like concrete or linoleum. These imprints or impressions might be contrasted with the shoe of a suspect or the tire of a car to see if they belong to the same object.
Thus, The term imprint is defined as to mark by or as if by pressure and the term impression is defined as the effect produced by impressing.

How many grams of sucrose will I add to the water (0.100 L) in order to make the 3 molal solution.
Answer:
mass = 102.69 g of sucrose
Explanation:
First, you need to use the correct expression of molality (m) which is the following:
m = moles / kg solvent (1)
According to the exercise, we need to get the grams, in other words, the mass of the sucrose. To get the mass, we need the moles and molecular weight of sucrose and use the following expression:
moles = mass / MM (2)
Now, if we replace (2) in (1) we have:
m = mass / MM * kg solvent (3)
From here, we solve for the mass and then:
mass = m * MM * kg solvent (4)
Now, then density of water is 1 kg/L, so, the volume of the water will be the same as it's mass, and the molality is 3 m. The molecular weight of the sucrose is (according to several sources) 342.3 g/mol. Replacing all the data in (4) we have:
mass = 3 mol/kg * 0.1 kg * 342.3 g/mol
mass = 102.69 g of sucroseHope this helps

A sample of sulfur dioxide occupies a volume of 6052 mL at 352 K and 892 mm Hg. What volume will the sulfur dioxide occupy at STP?
Answer:
5511.99 mL
Explanation:
Given data
Volume V1= 6052 mL
Temperature T1= 352K
Pressure P1= 892 mm Hg
At STP the parameters of gas are
Temperature T2= 273.15 K
Pressure P2= 760 mmHg
Applying the gas equation
P1V1/T1= P2V2/T2
Substitute to find V2 we have
892*6052/352= 760*V2/273.15
5398384/352= 760*V2/273.15
15336.31= 760*V2/273.15
Cross multiply
15336.31*273.15= 760*V2
4189113.0765= 760*V2
4189113.0765/760= V2
V2= 5511.99 mL
Hence the volume at STP is 5511.99 mL
Calculate the Density of the substances below to determine if they will float or sink in water.
Mass
Volume
Density
Float or Sink
45. Substance 1
90 ml
46. Substance 2
450 grams
35 grams
24 grams
70 ml
47. Substance 3
12 ml
Explanation:
If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.
Substance 1,
Mass, m = 450 g, Volume, V = 90 mL
Density = mass/volume
So,
[tex]d_1=\dfrac{450}{90}\\\\=5\ g/mL[/tex]
It will sink.
Substance 2,
Mass, m = 35 g, Volume, V = 70 mL
Density = mass/volume
So,
[tex]d_2=\dfrac{35}{70}\\\\=0.5\ g/mL[/tex]
It will float.
Substance 3,
Mass, m = 24 g, Volume, V = 12 mL
Density = mass/volume
So,
[tex]d_3=\dfrac{24}{12}\\\\=2\ g/mL[/tex]
It will sink.
