Answer:
A. Yes
B. –176 °C
Explanation:
A. Yes
B. Determination of the new temperature of the gas.
Let the initial pressure be P
From the question given above, the following data were obtained.
Initial pressure (P1) = P
Initial temperature (T1) = 19 °C
Final pressure (P2) = ⅓ P1 = ⅓P = P/3
Final temperature (T2) =?
Next, we shall convert 19 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T1) = 19 °C
Initial temperature (T1) = 19 °C + 273
Initial temperature (T1) = 292 K
Since the volume is constant, we can obtain the new temperature of the gas as illustrated below:
Initial pressure (P1) = P
Initial temperature (T1) = 292 K
Final pressure (P2) = P/3
Final temperature (T2) =?
P1/T1 = P2/T2
P/292 = P/3 /T2
P/292 = P/3T2
Cross multiply
P × 3T2 = 292 × P
Divide both side by P
3T2 = (292 × P)/P
3T2 = 292
Divide both side by 3
T2 = 292/3
T2 = 97.33 ≈ 97 K
Finally, we shall convert 97 K to celcius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 97
T(°C) = 97 – 273
T(°C) = –176 °C
Thus, the new temperature of the gas is –176 °C.

This is for my wonderful boy friend Putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
Never put my love out on the line
Never said "Yes" to the right guy
Never had trouble getting what I want
But when it comes to you, I'm never good enough
When I don't care, I can play 'em like a Ken doll
Won't wash my hair, then make 'em bounce like a basketball
But you make me wanna act like a girl
Paint my nails and wear high heels, yes, you
Make me so nervous that I just can't hold your hand
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack
I think I'd have a heart attack
Never break a sweat for the other guys
When you come around, I get paralyzed
And every time I try to be myself
It comes out wrong like a cry for help
It's just not fair; pain's more trouble than love is worth
I gasp for air; it feels so good, but you know it hurts
But you make me wanna act like a girl
Paint my nails and wear perfume for you
Make me so nervous that I just can't hold your hand
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack
I think I'd have a heart attack
The feelings got lost in my lungs
They're burning I'd rather be numb
And there's no one else to blame
So scared I take off, and I run
I'm flying too close to the sun
And I burst into fla-fla-flames
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack (Heart attack)
I think I'd have a heart attack
I think I'd have a heart attack
I think I'd have a heart attack

What do all things that are made of matter have in common?
Answer:
The common things among the three states of matter are: They are made up of small tiny particles. They have a particular mass and can occupy space. These three states have volume in it.
Answer:
Matter is any substance that has mass and takes up space. Everything is made of matter, so any object you can name consists of matter. Basically, if it takes up space and has mass, it's matter.

C3H8 + 5O2 → 3CO2+ 4H2O, if 5.75L of oxygen are consumed in the above reaction, how many L of carbon dioxide are produced?
Answer: 3.45 L carbon dioxide are produced
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}=\frac{5.75L}{22.4L}=0.257moles[/tex]
[tex]C_3H_8+5O_2(g)\rightarrow 3CO_2+4H_2O[/tex]
According to stoichiometry :
5 moles of [tex]O_2[/tex] produce = 3 moles of [tex]CO_2[/tex]
Thus 0.257 moles of [tex]O_2[/tex] will produce=[tex]\frac{3}{5}\times 0.257=0.154moles[/tex] of [tex]CO_2[/tex]
Volume of [tex]CO_2=moles\times {\text {Molar volume}}=0.154moles\times 22.4L/mol=3.45[/tex]
Thus 3.45 L carbon dioxide are produced

What coefficient would you place in front of O2 in order to balance this chemical equation:
2C2H6 + _?_O2 → 4CO2 + 6H2O
C)8 A) 6 R) 14 B) 7
Answer:
7 O2
Explanation:
My method involves counting all the elements in the equation. There must be an equal amount of each on both sides. Because it's asking for O2 only, look for compounds that deal with O2
So...CO2 and H2O only on the product side for this chemical equation.
Count the total O there is
CO2 has 2 O in one molecule, so 4 CO2 molecule is 8 Oxygen
H2O has 1 O in one molecule, so 6 H2O molecule is 6 Oxygen.
Your total O on the product side is 14
On the reactant side, the O2 is paired because O2 likes to be stable, so one O2 molecule has 2 O. This means that 2x = 14, which is 7.
Your answer is 7
Answer:
7 O2
Explanation:
You are given the balanced equation 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(ℓ) You are given rules for assigning oxidation numbers in Table 9.3 on page 604 of the student textbook. Compare the oxidation numbers of the atoms of each element on both sides of the equation. ... Therefore, the reaction is a redox reaction.

1. How is the activity series useful in predicting chemical behavior?
Answer:
It shows the most reactive to least reactive, so that we can predict whether certain reactions will occur. Any metal can replace any metal below it, but not above it.
Explanation:
1. The activity series is a type of ordering system for elements, which ranks how reactive a certain element is in relation to other elements.
2. The activity series determines the level of reactivity based on how well a certain element can displace hydrogen gas from acidic solutions and water.
3. The activity series of metals is an empirical tool used to predict products in displacement reactions and reactivity of metals with water and acids in replacement reactions and ore extraction.
4. It can be used to predict the products in similar reactions involving a different metal.
5. It helps in predicting whether a reaction will occur, and if so what the product will be.
