What is the overall reaction equation
Answer:
If m or n is zero, the reaction is zero order in A or B, respectively, and the rate of the reaction is not affected by the concentration of that reactant. The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order
(m + n = 1 + 1 = 2).
Explanation:
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

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

Find the mass of 1.25 moles Ca(OH)2.
According to the mole concept, the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Mass=number of moles×molar mass=1.25×74.09=92.61 g.
Thus,the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.

A process that releases heat, such as freezing or condensation is called?
Answer:
exothermic
Explanation:
An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.

How does salinity vary with freezing and melting?
Question 3 options:
Freezing increases salinity, while melting decreases salinity.
Both freezing and melting decrease salinity.
Freezing decreases salinity, while melting increases salinity.
Both freezing and melting increase salinity.
Answer:
For every 5 psu increase in salinity, the freezing point decreases by 0.28 degrees Celsius (0.5 degrees Fahrenheit); thus, in polar regions with an ocean salinity of about 32 psu, the water begins to freeze at -1.8 degrees Celsius (28.8 degrees Fahrenheit).
Explanation:
Freezing increases salinity, while melting decreases salinity.

how many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m
Answer:
two
Explanation:
The number of significant figures needed in the answer is 2.
This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.
Here the numbers being multiplied are;
1.31m
6.5m
1.31m has 3 significant figures
6.5m has 2 significant figures.
So, the product will have 2 significant figures
