A piston contains 0.39L of air at 1.0 atm. If the pressure on the piston is increased to 5.6 atm, what is the new volume?
Answers
The new volume : 0.07 L
Further explanationBoyle's Law
At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
P₁=1 atm
V₁=0.39 L
P₂=5.6 atm
[tex]\tt V_2=\dfrac{P_1.V_1}{P_2}\\\\V_2=\dfrac{1\times 0.39}{5.6}\\\\v_2=\boxed{\bold{0.07~L}}[/tex]

Genes can be best defined as:
A. the traits expressed by the organism
B. the DNA that make up a chromosome
C. a form of reproduction
D. section of DNA that codes for a specific trait
Answers
Answer:
D. section of DNA that codes for a specific trait
Explanation:
Genes are sections of the DNA that codes for a specific trait. They are simply defined as the basic physical and functional unit of hereditary.
Genes are usually found encoded in the DNA. The effects produced by genes result from their coordination of certain protein synthesis activities. Inheritance is attained when genes are passed from parents to offspring.List three types of cyclic motion. FIRST GET BRAINLEIST

What mass (in g) of lithium metal can be produced by the electrolysis of molten LiCl for 23.93 hr with an electrical current of 17.7?
Answers
Answer:
1.828 g
Explanation:
The half-reaction is:
Li⁺ + 1e⁻ → Li(s)First we calculate the coulombs:
Coulombs = Amperes * seconds23.93 hr * 60 = 1435.8 sCoulombs = 17.7 A * 1435.8 s = 25413.66 CThen we calculate the number of lithium moles, using Faraday's constant:
25413.66 C * [tex]\frac{1mol(e^-)}{96485C} *\frac{1molLi}{1mol(e^-)}[/tex] = 0.2634 mol LiFinally we convert moles to grams:
0.2634 mol Li * 6.941 g/mol = 1.828 gWhat will the weather most likely be like if a low pressure system settles over an area

Consider the following isomerization reactions of some simple sugars and values for their standard Gibbs free energy ΔGo:reaction A: glucose-1-phosphate rightarrow glucose-6-phosphate, ΔGo = -7.28 kJ/mol reaction B: fructose-6-phosphate rightarrow glucose-6-phosphate, ΔGo = -1.67 kJ/molCalculate for the isomerization of glucose-1-phosphate to fructose-6-phosphate.Calculate the equilibrium constant K for the isomerization of glucose-1-phosphate to fructose-6-phosphate at 298 K.
Answers
Answer:
Explanation:
glucose-1-phosphate → glucose-6-phosphate, ΔGo = -7.28 kJ/mol
fructose-6-phosphate → glucose-6-phosphate, ΔGo = -1.67 kJ/mol
subtracting the equation
glucose-1-phosphate - fructose-6-phosphate = 0 , ΔGo = -7.28 - ( -1.67 ) kJ / mol
glucose-1-phosphate = fructose-6-phosphate ΔGo = - 5.61 kJ / mol
- ΔGo = RT lnK
5.61 x 10³ = 8.31 x 298 x lnK
lnK = 2.265
K = 9.63 .
