Answer:
0.012atm pressure
Explanation:
pressure is inversly proportional to volume. Mathematically,
V1/P1=V2/P2
Hey there!
The answer is C, hydrosphere.
The prefix "hydro" means water.
"Sphere" relates to Earth.
The asthenosphere and lithosphere are parts of the crust and mantle of the earth.
The atmosphere is the gases that surround the planet.
Hope this helps!
Answer:
306.6g/mol
Explanation:
To calculate molecular weight you need to know how many grams ou have in a determined amount of moles of substance. As you have the mass of the sample (1.42g), you need to find how many moles are, as follows:
The reaction of the acid HX with the base YOH is:
HX + YOH → H₂O + YX
<em>1 mole of acid reacts per mole of base.</em>
<em />
In a titration, the solution turned pink when moles base = moles acid.
Moles of base that the student added (Using the volume and molarity of the solution) are:
32.48mL = 0.03248L ₓ (0.1426 moles base / L) = 0.004632 moles of base
As the titration is in equivalence point, there are 0.004632 moles of the acid
Molecular weight (Ratio between grams of sample and its moles) is:
1.42g / 0.004632 moles =
<h3>306.6g/mol</h3>
Protons and neutrons make up most of an atom's mass. Electrons have almost no mass.
Answer:
b.what type of object broke the glass
Explanation:
The point of intersection of all the fracture patterns of the window speaks to the shape, type and dimension of the object that broke the glass.
