Answer:
2.47L
Explanation:
Using the combined gas law equation as follows:
P1V1/T1= P2V2/T2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
P1 = 705mmHg
P2 = 760mmHg (STP)
V1 = 3.00L
V2 = ?
T1 = 35°C = 35 + 273 = 308K
T2 = 273K (STP)
Using P1V1/T1= P2V2/T2
705 × 3/308 = 760 × V2/273
2115/308 = 760V2/273
Cross multiply
308 × 760V2 = 2115 × 273
234,080V2 = 577,395
V2 = 577,395 ÷ 234,080
V2 = 2.47L
A piece of copper (c = 0.385 joules over grams times degrees Celsius) undergoing a temperature change from 150°C to 225°C absorbs 3,500 joules of energy. What is the mass of the piece of copper? Express the answer to the nearest whole number. grams
The mass of the piece of copper, to the nearest whole number is 121 grams.
Given the following data:
Specific heat capacity of copper = 0.385 J/g°CInitial temperature = 150.0°CFinal temperature = 225.0°CQuantity of heat = 3,500 JoulesTo calculate the mass of the piece of copper, to the nearest whole number:
Mathematically, quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.[tex]\theta[/tex] represents the change in temperature.Making "m" the subject of formula, we have:
[tex]m = \frac{Q}{c\theta}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m = \frac{3500}{0.385(225-150)}\\\\m = \frac{3500}{0.385 \times 75} \\\\m = \frac{3500}{28.875}[/tex]
Mass, m = 121.21 ≈ 121 grams

Find the value of x and y, given the following matrix equation: matrix x = y =
Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.
How to determine the value of x and y.In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.
x² - 4 = 32 ...........(upper part)
y + y - 4 = y + 6 ....(lower part)
Next, we would solve for x:
x² - 4 = 32
x² = 32 + 4
x² = 36
x = ±√36
x = ±6.
For the value of y, we have:
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 10
y = 16.

describe one way an invasive species, such as the zebra mussel, can decrease the carrying capacity for a native species in an ecosystem.
The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.

a canoe can be paddled at 7 mph through a placid lake the stream flows at 3 mph
Using system of linear equations the distance at the fisherman and the bobbler meets ls 8 miles
Speed in still waters = 7 mph
Stream speed = 3 mph
Upstream speed of canoe = 7 - 3 = 4 mph
Distance between fisherman and bobbler = 14 miles
Let seperation distance = d
Meeting distance = 14 - d

Answer:
Throughout the play, Wilde uses puns to connect the name Ernest to the word earnest. When Cecily says that she has always wanted to marry someone named Ernest, she implies that she also wants someone earnest who “inspire[s] absolute confidence.” In this scene, however, Algernon is lying to her about who he is. His deception suggests that no one can ever have “absolute confidence” that others are being earnest.
Explanation:
Wilde utilizes puns throughout the play to tie the name Ernest to the term earnest.
The Importance of Being Earnest:Ernest is a given name that is derived from the word earnest. The term earnest refers to sincerity, yet Ernest in "The Importance of Being Earnest" is anything but.
Ernest adopts many identities or occupations, but none of them are authentic since he isn't himself. Finally, he understands why it is critical to be "honest" and loyal to himself. At the end of the novel, being "earnest" and being "Ernest" have the same meaning, since the main character, Ernest, learns the significance of being true to oneself.
