Granulated sugar has a greater surface area showing than sugar cubes do. Since it has more surface area showing, more sugar molecules can interact with the water at the same time allowing it to dissolve faster than a cube of sugar where only the molecules on the outside of the cube are exposed to the water.

How many milliliters of 0.260 m na2s are needed to react with 35.00 ml of 0.315 m agno3?
allochka39001 [22]

The complete balanced chemical reaction is:

2 AgNO3 + Na2S --> 2 NaNO3 + Ag2S

 

First let us calculate the number of moles of AgNO3.

moles AgNO3 = 0.315 M * 0.035 L

moles AgNO3 = 0.011025 mol

 

From the reaction, 1 mole of Na2S is needed for every 2 moles of AgNO3 hence:

moles Na2S required = 0.011025 mol AgNO3 * (1 mol Na2S / 2 mol AgNO3)

moles Na2S required = 5.5125 x 10^-3 mol

 

Therefore volume required is:

volume Na2S = 5.5125 x 10^-3 mol / 0.260 M

<span>volume Na2S = 0.0212 L = 21.2 mL</span>

List and describe the three rock types in the rock cycle including two or more processes involved in the formation of each type
Ludmilka [50]

Answer:    The three main rock types are igneous, metamorphic and sedimentary.

   The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.

   Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
