Balanced equation
Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄
Further explanationGiven
Reaction
Mg3(PO4)2 + Al(NO3)3 → Mg(NO3)2 + AlPO4
Required
Balanced equation
Solution
Give a coefficient :
Mg₃(PO₄)₂ + aAl(NO₃)₃ → bMg(NO₃)₂ + cAlPO₄
Make an equation :
Mg, left = 3, right=b⇒b=3
P, left=2, right=c⇒c=2
Al, left=a, right=c⇒a=c⇒a=2
The reaction becomes :
Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄

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

Question 7 (5 points)

One mole of zinc has a mass of 65.4 grams. Approximately how many atoms of zinc are present in one mole of zinc?
Answer:
6.02 x 10²³ atoms
Explanation:
The number of moles present in 1 mole of zinc will be 6.02 x 10²³ atoms. This is because a mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³ atoms.
A mole is simple a convenient way of estimating the number particles within a substance.
So every 1 mole of a substance contains the same number atom in there.
For the give zinc, since it is 1 mole, it will contain 6.02 x 10²³ atoms
they've changed the answer, but 6.02 x 1023 is still right. the new answer is just 6 x 1023.(6.02 rounded to the nearest integer)
_is a change in direction or speed
-velocity
-force
-deceleration
-mass
-acceleration

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
