If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the
gas in atm?
Answer:
0.87 atmExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question
2.47 L = 2470 mL
We have
[tex]P_2 = \frac{765 \times 2.78}{2470} = \frac{2142}{2470} \\ = 0.867206...[/tex]
We have the final answer as
0.87 atmHope this helps you

A. 4-fluorobutane
B. 2-fluorobutane
C. 1-fluorobutane
D. 1-fluoropentane
Answer:
The correct answer is (C)
Which is "1-fluorobutane"
Explanation:
Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)
The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.
In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.
Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.
Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

How many grams of water will be produced when 1.6 moles of ethanol (CH3CH2OH) are burned completely? Enter a number only (no units) and express your answer using the correct number of significant figures.
Answer:
86
Explanation:
The reaction that takes place is:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂OFirst we convert moles of ethanol to moles of water:
1.6 mol ethanol * [tex]\frac{3molH_2O}{1molEthanol}[/tex] = 4.8 mol H₂OThen we convert moles of water to grams of water, using its molar mass:
4.8 mol H₂O * 18 g/mol = 86.4 gSo 84.6 grams of water will be produced.
The mass of water, H₂O produced when 1.6 moles of ethanol, C₂H₅OH are completely burned is 86.4 g
We'll begin by writing the balanced equation for the reaction. This is given below
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
From the balanced equation above,
1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.
Next, we shall determine the number of mole of H₂O produced by the reaction of 1.6 moles of C₂H₅OHFrom the balanced equation above,
1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.
Therefore,
1.6 moles of C₂H₅OH will react to produce = 1.6 × 3 = 4.8 moles of H₂O.
Finally, we shall determine the mass of 4.8 moles of H₂O.Mole of H₂O = 4.8 moles
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H₂O =?Mass = mole × molar mass
Mass of H₂O = 4.8 × 18
Mass of H₂O = 86.4 gThus, the mass of water obtained from the reaction is 86.4 g

If I change the volume of a solution from 5.00 L to 10.0 L, what was the new
concentration if the original concentration was 4.0 M? Please help me as soon as possible with explanation.
The new concentration = 2 M
Further explanationDilution is a process of decreasing the concentration of a solution by adding a number of solvents
Can be formulated
M₁V₁=M₂V₂
M₁ = Initial Molarity
V₁ = Initial volume
M₂ = Final Molarity (after dilution)
V₂ = Final volume (after dilution)
V₁=5 L
V₂=10 L
M₁=4 M

Pure sodium metal reacts violently with water according to the equation below
Na + H2O - NaO + H2
17 mol
If 0.75 mol of Na is placed in 500 g of
H,O how many moles of hydrogen
gas will be produced?
0.75 mol
28 mol
1.5 mol
Answer:
0.75 mol
Explanation:
Given data:
Number of moles of Na = 0.75 mol
Mass of water = 500 g
Moles of hydrogen gas produced = ?
Solution:
Chemical equation:
Na + H₂O → NaO + H₂
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 500 g/ 18 g/mol
Number of moles = 27.8 mol
now we will compare the moles of hydrogen gas with both reactant.
Na : H₂
1 : 1
0.75 : 0.75
H₂O : H₂
1 : 1
27.8 : 27.8
sodium will act as limiting reactant it produced small number of moles of hydrogen gas as compared to water.
Thus, number of moles of hydrogen gas are 0.75 mol.

what is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent
The dilution factor : 100
Further explanationThe dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution
From equation of dilution :
M₁V₁=M₂V₂
[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]
Volume of aliquot = 0.1 ml
Volume of diluent = 9.9 ml
So final volume :
[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]
The dilution factor (DF) :
[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]

(seiect all that apply)
None these is qualitative data
The sound of a person's voice
The weight of person
The hair color of a person
The body temperature of a person
Answer:
The hair color of a person
Explanation:
The correct answer would be the hair color of a person.
Qualitative data are data that cannot be measured with any instrument but can only be used to characterize. Unlike quantitative data, these kinds of data can only be observed and recorded but cannot be assigned numerical values, except if coded.
The sound of a person's voice can be quantitative on one hand and qualitative on the other. The intensity of a sound can be measured using a decibel meter and quantitatively assigned a figure, whereas, the quality of the sound can only be characterized and not measured.
Both the weight and the body temperature of a person can be measured using a weighing balance and a thermometer respectively and hence, are considered to be quantitative data when collected.
The color of the hair of a person cannot be measured but can only be observed and characterized. Hence, hair color data constitute qualitative data.

The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.*I have confidence you can graph that*
