D. Synthesis cause A + B --> AB
Equation: 2Na + Cl2 --> 2NaCl
We can calculate for temperature by assuming the equation
for ideal gas law:
P V = n R T
Where,
P = pressure = 1.80 atm
V = volume = 18.2 L
n = number of moles = 1.20 moles
R = gas constant = 0.08205746 L atm / mol K
Substituting to the given equation:
T = P V / n R
T = (1.8 atm * 18.2 L) / (1.2 moles * 0.08205746 L atm /
mol K)
T = 332.70 K
We can convert K unit to ˚C unit by subtracting 273.15
to Kelvin, therefore
T = 59.55 ˚<span>C</span>
Is this a scienctif question cuss if so it not only helps u with math there’s a lot of subsists like history math English etc....
Answer:
25 mph
Explanation:
So we have to find the unit rate, or you could use the DTS triangle, but both say you have to divide, so our equation is:
176 ÷ 7 = 25.14
But I'm going to round that
So the train is traveling at 25 mph
hope this helps:/
A simple way to go about this is that we look at the solubility curve, on the x axis we first look at the temperature and then the corresponding value of solute/100g H2O on the y axis, from the 4 curves above only NaNO3 has a curve that can accommodate 80g of salt at 40 without being Saturated since at 40 degrees it can accommodate 105g of salt to become completely Saturated.
