He picture below shows a container that Tim uses to freeze water:

Alja [10]

You have a formula : $V= \pi r^2h$ . You just have to apply it. It would gives :

$V= \pi (2)^2(8)$
$V=32 \pi$
$V=100.48cm^3$

Now, use your mind. How many would be needed to make 2000 cm3.

$\frac{2000}{100.48}$
$=19.94 = 20$

Therefore <span>the minimum number of identical containers that Tim would need to make 2,000 cm3 of ice is 20 (option D).

Hope this helps !

What is the Wt% of SiO2 in augite?<br><br> (Ca, Fe, Mg, Na)(Mg,Fe,Al) (Si,Al)2 O6

vaieri [72.5K]

Answer:

The weight% of $SiO_2$ in augite is 13.16 %.

Explanation:

Atomic mass of calcium = 40 g/mol

Atomic mass of iron = 56 g/mol

Atomic mass of magnesium = 24 g/mol

Atomic mass of sodium = 23 g/mol

Atomic mass of aluminum = 27 g/mol

Atomic mass of silicon = 28 g/mol

Atomic mass of oxygen = 16 g/mol

Mass of $SiO_2=28 g/mol+ 2\time 16 g/mol=60 g/mol$

Molar mass of the augite $(Ca, Fe, Mg, Na)(Mg,Fe,Al)(Si,Al)_2 O_6$ = M

$M=40 g/mol+2\times 56 g/mol+2\times 24 g/mol+23 g/mol+3\times 27 g/mol+2\times 28 g/mol+6\times 16 g/mol=456 g/mol$

Weight% of $SiO_2$ in augite:

$w\%=\frac{60 g/mol}{456 g/mol}\times 100=13.16\%$

When continental crust and oceanic crust collide, ________ crust goes under (subducts) ___________ crust. _____________ then for

Advocard [28]

Answer:

The oceanic crust is forced under the continental crust and into the mantle. Crompression causes mountains to form on the continental crust. Material in the mantle melts as volatiles seep out of the oceanic crust. The molten material rises to the surface, forming a continental volcanic arc.
