The pressure of the Moxie's tank in the summer will be 110.5 atm.
The correct option is C.
What is pressure law?According to the pressure law, if the volume remains constant, for a given mass of gas, the pressure applied to the container's sidewalls is directly proportional to the gas's absolute temperature.
Briefing:This law can be expressed mathematically as
P₁/T₁ = P₂/T₂
where
P₁ is the starting pressure.
The final pressure is P₂.
The starting temperature is T₁
The final temperature is T₂
The pressure of the gas increases as its temperature does.
As a result, since summertime temperatures are higher than wintertime temperatures, the pressure within the Moxie's tank will be higher than 50 atm throughout the summer.

A chemistry student needs 65.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is 1.10 g-cm^- 3. Calculate the volume of pentane the student should pour out. Be sure your answer has the correct number of significant digits.
The volume of the pentane the student should pour out, given that he needed 65.0 g of it is 59 cm³
How to determine the volumeFrom the definition of density, we can obtain an expression to calculate volume. This is illustrated below:
Density = mass / volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
With the above formula, we can obtain the volume of the pentane as follow:
Mass of pentane = 65 gramsDensity of pentane = 1.10 g/cm³ Volume of pentane = ?Volume = mass / density
Volume = 65 / 1.10
Volume = 59 cm³
Thus, the volume of the pentane is 59 cm³

For the reaction of calcium chloride and sodium oxalate, write: a chemical equation that represents the reaction including all appropriate phase labels (e.g. (s), (l), (aq)).
The chemical equation that represents the reaction is NaCl(s) ⇒Na+(aq) + Cl-(aq).
A mixture of sodium sulfate and calcium chloride produces four crystals sodium sulfate calcium chloride sodium chloride and calcium sulfate. Calcium chloride dissolved in water dissociates into ions according to the formula This is an example of a precipitation reaction. This occurs when two aqueous solutions combine to form a precipitate and by-products. It is also usually water-based.
A balanced equation is an equation of a chemical reaction in which the number of atoms and the total charge of each element in the reaction is the same for both reactants and products. In other words, mass and charge are balanced on both sides of the reaction. Widely used as an acid laundry detergent, oxalic acid effectively removes rust and ink stains because it converts most insoluble iron compounds to soluble complex ions.

A student poured a liter of liquid water into a jar and then placed a lid on the jar. Compare and contrast the liquid water and the water vapor in the jar to complete the table.
The liquids are less energetic than the gases. They have a definite volume unlike the gases but like the gases, they have no definite shape.
What are the states of matter?Matter is anything that has mass and occupy space. We know that matter is composed of particles. The particles that compose matter are known to differ in the way that they move about. All the particles of each of the states of matter do not have the same amount of energy. Some states of matter have particles that are more energetic than other particles of matter.
Let us note that the liquid state of matter is less energetic then the gaseous state of matter. This is because the particles that compose a gas are always moving at a very high speed. The particles that compose a liquid have lesser energy.
On the other hand, a gas has no definite volume or shape while a liquid does not have a definite shape but it has a definite volume.

How many grams of Br are in 115 g CaBr₂?
Answer: 95.7 g Br
Explanation: Molecular weight of Ca = 40.78
Molecular weight of Br is 79.9.
Molecular weight of CaBr2 is 192g/mol
115g CaBr2 x 1 mol CaBr/192g = 0.6 x 2 mol Br/1mol CaBr2 = 1.2 mol Br
1.2 mol Br x 79.9g Br/mol Br = 95.7g Br
What volume of sodium hydroxide (0.167 M) is needed to titrate 18.53 mL of perchloric acid (HClO4 (aq)) with molarity of 0.242 M ? Answer in mL with one decimal place- you do not need to include units in your response.
The volume (in mL) of the 0.167 M sodium hydroxide, NaOH solution needed is 26.9 mL
How to determine the volume of NaOHThe balanced equation for the reaction is given below:
HClO₄ + NaOH —> NaClO₄ + H₂O
The mole of the acid, HClO₄ (nA) = 1The mole of the base, NaOH (nB) = 1The volume of NaOH can be obtained as follow:
Molarity of base, NaOH (Mb) = 0.167 MVolume of acid, HClO₄ (Va) = 18.53 mL Molarity of acid, HClO₄ (Ma) = 0.242 MVolume of base, NaOH (Vb) =?MaVa / MbVb = nA / nB
(0.242 × 18.53) / (0.167 × Vb) = 1
4.48426 / (0.167 × Vb) = 1
Cross multiply
0.167 × Vb = 4.48426
Divide both side by 0.167
Vb = 4.48426 / 0.167
Vb = 26.9 mL
