a. 65.316 mL + 0.05 mL.
b. 5.2 cm + 0.1 cm
c. 1.8642 km ± 0.22 km
d. 16.8°C ±1°C
Answer: a. 65.37 mL
b. 5.3 cm
c. 2.08 km (plus) or 1.64 km (minus)
d. 18°C (plus) or 16°C (minus)
Explanation:
The way significant figures work when you're adding or subtracting, is you go to the answer with the least amount of decimal places. Take a. for example; you have 65.316 (3 places after the decimal) and 0.05 (2 places after the decimal place). Based off of this, you would round your answer to two places after the decimal. And when you have a whole number, like in d. you round to the nearest whole number, since there aren't any decimal places to round your answer to.

Question:
If butane had a volume of 500 ml. at a pressure of 1.5 atm and a temperature of 20 °C, what would the new volume of the gas be at a temperature of 30 °C and a pressure of 500 Torr?
Solution Given:
Let P be the pressure V be volume and and T be temperature.
Volume of Butane [[tex]V_1[/tex]] = 500 ml
Pressure of Butane [[tex]P_1[/tex]] = 1.5 atm
Temperature [[tex]T_1[/tex]] =20°C=20+273=293K
New Volume of Butane [[tex]V_2[/tex]] = ?
New Pressure of Butane [[tex]V_2[/tex]] =500 Torr=500*0.00131579=0.657895 atm
Note: 1 Torr= 0.00131579 atm
New Temperature of Butane [[tex]V_2[/tex]] =30°C=30+273=303K
Now
By using combined gas law equation:
[tex]V_2=V_2*\frac{P_1*T_2}{P_2*T_1}[/tex]
[tex]V_2=500*\frac{1.5*303}{0.657895*293}=1178.9 ml[/tex]

A moderate antiseptic used topically to treat minor burns, scrapes, and cuts is hydrogen peroxide. As a mouth rinse, it can be used to assist clear mucus or soothe minor oral irritation (caused, for example, by canker/cold sores, or gingivitis).
Stronger than chlorine, chlorine dioxide, and potassium permanganate, hydrogen peroxide is a potent oxidant.
Human blood is exposed to a hydrogen peroxide solution, which causes the peroxide to break down and release oxygen. Before transfusion, this process has been utilized to oxygenate banked blood.
When hydrogen peroxide comes into contact with skin, a chemical process takes place that causes hydrogen peroxide to turn white. When the solution oxidizes, oxygen bubbles that arise give the mixture a white, foamy appearance.

The ability of an atom or functional group to draw electrons to itself is known as an electronegativity in chemistry. An atom's electronegativity is influenced by both its atomic number and how far away from its charged nuclei its valence electrons are located.
The ability of an atom to draw shared electrons in a covalent connection is referred to as electronegativity. The stronger an element attracts the shared electrons, the higher its degree of electronegativity.
The propensity of an atom to attract other atoms when it is combined is known as an element's electronegativity. Additionally, a pair of bound electrons are shared. In contrast, an element's electropositivity refers to an atom's propensity to contribute electrons while also withdrawing from covalent connections.

The solubility product, ksp of PbBr₂ is 2.102 × 10⁻⁶
What is solubility?The solubility of a solute is defined as the maximum amount of that solute that can be dissolved in a known quantity of solvent at a given temperature.
What is a solubility product?Some salts are sparingly soluble in a solvent. For them, we calculate the solubility product.
It is an equilibrium constant that defines the relationship between a solid and its respective ions in an aqueous solution in equilibrium.
The greater the solubility product, the greater the solubility and vice versa.
Here, the solubility of PbBr₂ = 2.96 g/l
Molar solubility of PbBr₂ = [tex]\frac{2.96}{molar mass of PbBr_2}[/tex] = 2.96/367 = 8.07 × 10⁻³
At equilibrium,

1 mole of PbBr2 dissociates into 1 mole of Pb²⁺ ions and 2 moles of Br⁻
Let the molar concentration of Pb²⁺ be x, then the molar concentration of Br⁻ is 2x
Ksp = x.(2x)²

Substitute, x = 8.07 × 10⁻³
Ksp = 4 (8.07 × 10⁻³)³

A single slit with a width of 2019 * 109 m creates its initial minimal for 624 nm light at an angle of 18°.
How does diffraction work?
Waves spreading outward around obstructions are known as diffraction. Diffraction happens with sound, electromagnetic radiation like light, X-rays, and gamma rays, as well as with incredibly minuscule moving particles like atoms, neutrons, and electrons that exhibit wavelike qualities. Diffraction prevents the creation of sharp shadows as one of its effects. In order to spread out and illuminate regions at which a shadow is anticipated, light must be bent around corners, which is known as diffraction.
Calculation:
Provided for a single slit, m=1

How do I find last significant figure. Please give a thorough explanation because I do not understand this (40 points)
Use 46.7350 as example
Answer:
Below I have listed a write up that helped me!
Explanation:
Here are some general rules regarding significant figures (or sigfigs!)
1) any number that is not a 0 is always a sigfig. In your example, the significant figures would be 4, 6, 7,3,5 and *0. (*there are special rules regarding the number 0)
2) If a 0 is between two non-zero digits (sigfigs), it will be a significant figure. For example, in the number 305, the 0 between the 3 and 5 would be considered a significant figure.
3) 0's that "lead", or are to the left of significant figures are NOT significant figures. For example, in the number 0.002, there would be only one significant figure, which is the 2.
4) 0's that "trail", or are to the right of a significant figure behind a decimal place, are significant figures. For example, in the number 3.1250, the 0 at the end would be considered significant. There are five sigfigs total in this number. The trailing 0 in your example would be significant!
5) However, regarding the rule above, if the number DOES NOT have a decimal place and has trailing 0's, those 0's will not be considered significant figures. For example, in the number 5,320, the 0 at the end would not be significant and there would be three sigfigs in this number.

P is the pressure of the hydrogen gas = 1.7 atmVis the volume of the hydrogen gas = ?n is the number of the hydrogen gas = 0.25 moleR is the universal gas constant = 0.082 atm L/mole KT is the temperature of the sample = 35°C = 35 + 273 = 308 KBy putting all the values of the given data like pressure temperature universal gas constant and number of moles in equation (i) we get ,
1.7 atm×V = 0.25 mole ×0.082 × 208 K
V = 0.25 mole ×0.082atm L /mole K × 308 K /1.7 atm
