Substances that form during a chemical change typically don't exhibit the same properties as the original substance. If they do, that is referred to as a "physical change".

Hoping I helped, and I would appreciate the brainliest answer! :)

No they do not and I agree with the above it’s a physical change

The volume of a gas is 200.0 mL at 275 K and 92.1 kPa. Find its volume at STP.
ycow [4]
To solve this question we will use ideal gas equation:
p*V=n*R*T
Where:
p = pressure
V = volume
n = number of moles
R = gas constant
T = temperature

We can rearrange formula to get:
\frac{p*V}{T} =n*R
We are working woth same gas so we can write following formula. Index 1 stands for conditions before change and index 2 stands for conditions after change.
\frac{ p_{1}*V_{1} }{T_{1}} = \frac{ p_{2}*V_{2} }{T_{2}}

We are given:
p1=92.1kPa = 92100Pa
V1=200mL = 0.2L
T1=275K
p2= 101325Pa
T2=273K
V2=?

We start by rearranging formula for V2. After that we can insert numbers:
{ p_{1}*V_{1} *T_{2}} = { p_{2}*V_{2}*T_{1} } \\  \\ V_{2}= \frac{p_{1}*V_{1} *T_{2}}{ p_{2}*T_{1}}  \\  \\ V_{2}=  \frac{92100*0.2*273}{101325*275}  \\  \\ V_{2}= 0.18L=180mL

How many volts does it take to push 2 amperes of current through 20 ohms of resistance?
vodomira [7]

As we know V=IR

So, R= 20 ohms, I= 2 A

Therefore, V= 2*20 = 40 V

Electric Voltage

The difference in electric potential between two points, also known as voltage, electric potential difference, electric pressure, or electric tension, determines how much labour is required to move a test charge between the two sites in a static electric field. Volt is the name of the derived unit for voltage (potential difference) in the International System of Units. 1 volt equals 1 joule (of work) for 1 coulomb, is how to work per unit charge is stated in SI units (of charge). Power and current were utilized in the previous SI definition for the volt, and the quantum Hall and Josephson effect was incorporated in 1990. As of 2019 fundamental physical constants have been employed in the definition of all SI units and derived units.

An airplane travels 2400 km at a speed of 600 km/h, decreases its speed to 400 km/h for the next 1200 km and travels the last 2,
Alexus [3.1K]
Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??

2400/600 = 4hours.

Do this for all three and add up the hours.

Total time: 12 hours

Average speed is the total distance / total time.

So,

Add up all the distances and divide by 12.

(2400+1200+2500) / 12

Average speed: 508.33333333 km/h
