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.

Answers

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.

C3H8 + 5O2 → 3CO2+ 4H2O, if 5.75L of oxygen are consumed in the above reaction, how many L of carbon dioxide are produced?

Answers

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

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
