Brilliant_brown [7]4 years ago

If we look at the sugar-water phase diagram;
at 80° C : 26% of water will dissolve 74% of sugar
C =  m / ( m + 1000 g ) · 100
74 = m / ( m + 1000 g ) · 100
0.74 = m / ( m + 1000 g )
m = 0.74 · ( m + 1000 g )
m = 0.74 m + 740 g
m - 0.74 m = 740 g
0.26 m = 740 g
m = 740 g : 0.26
m = 2,846.15 g ≈ 2,846 g
Answer:
m ( sugar ) = 2,846 g.

What is the empirical formula for a compound if a sample contains 3.72 g of P and 21.28 g of Cl
fenix001 [56]
M(P)=3.72 g
M(P)=31 g/mol

m(Cl)=21.28 g
M(Cl)=35.5 g/mol

n(P)=m(P)/M(P)
n(P)=3.72/31=0.12 mol

n(Cl)=m(Cl)/M(Cl)
n(Cl)=21.28/35.5=0.60 mol

P : Cl = 0.12 : 0.60 = 1 : 5

and this is the second one,

the tilt of the Earth on its axis

Seasons change because of the tilt of the Earth and the planet's movement around the Sun. Did you know? It takes about 365.25 days for the Earth to orbit the Sun. We have leap years to make up for the extra ¼ day!

<h3>What is Geothermal energy?</h3>

Geothermal energy is a special type of sustainable renewable source of clean energy that emerges from thermal (temperature) differences on the Earth, e.g., within geysers and similar geological formations.

In conclusion, geothermal energy is not used more often because it's hard to find geothermal energy sources that are close to the surface (Option A).
