How is the weathering of rocks by water different from the weathering of rocks by ice?

Chemistry

ehidna [41]2 years ago

Answer:

The formation of ice can also break rocks. If water gets into a crack in a rock and then freezes, it expands and pushes the crack further apart. When the ice melts later, water can get further into the crack. When the water freezes, it expands and makes the crack even bigger.

Analyze the data and determine the actual concentration of calcium chloride in the solution. Show all calculations and report in
Rus_ich [418]

Answer:

2.21% wt/v

Explanation:

The mass/volume percentage, %wt/v, is an unit of concentration used in chemistry defined as 100 times the ratio of the mass of solute in g (In this case, CaCl2 = 1.77g) and the volume of solution in mL = 80mL

The %wt/v of this solution is:

%wt /v = 1.77g / 80mL * 100

%wt/v = 2.21% wt/v

Why must soft iron be used with an electromagnet?
7nadin3 [17]
The soft iron<span> inside the coil makes the magnetic field stronger because it becomes a magnet itself when the current is flowing. </span>Soft iron is used<span> because it loses its magnetism as soon as the current stops flowing.</span>

Diamond has a density of 3.52 g/ml. what is the volume in cubic centimeters of a diamond with a mass of 15.1 g? 4.3 cm3 4.29 cm3
Kamila [148]
Density of 3.52g/ml means for each milliliter of space there are 3.52 grams of diamond.

To set the stage:
\frac{3.52}{1}  =  \frac{15.1}{x}
Set the denominators equal:
\frac{3.52x}{x}  =  \frac{15.1}{x}
Remove the denominators:
3.52x = 15.1
Isolate x by dividing both sides by 3.52:
x = 4.289772 {cm}^{3}

A horse runs 1 km in 15 s. What is the average speed
Reptile [31]

The average speed of the horse for the entire motion is 66.67 m/s.

The given parameters;

  • <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
  • <em>time of motion of the horse, t = 15 s</em>

The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.

The average speed of the horse is calculated as follows;

average\ speed = \frac{distance}{time} \\\\average\ speed =  \frac{1000 \ m}{15 \ s} = 66.67 \ m/s

Thus, the average speed of the horse for the entire motion is 66.67 m/s.
