Answer:

Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock.

Answer:

sedimentary rock, rock formed at or near Earth's surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from solution at normal surface temperatures (chemical rock). ... These processes produce soil, unconsolidated rock detritus, and components dissolved in groundwater and runoff.

A small sample of an organic compound (a nonelectrolyte) was added to benzene (Freezing point = 5.5°C)

Alja [10]

The new lowered freezing point of the benzene mixture is determined as 2.4°C.

<h3>Effect of impurities in freezing point</h3>

The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.

Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C

New freezing point = 5.5°C - 3.1°C = 2.4°C

Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

Create a story and describe the motion (in meters) of an object that has traveled a distance but has no displacement.

aleksley [76]

Answer:

Circular motion

Explanation:

Consider a car race, where you need to finish one lap in a circuit. Her the start line and the finish line are the same. So , where you start, is where you will be reaching after the race is done. So, the displacement here is <em>Zero</em> , since displacement is the distance from initial point to final point. But, as one can see, the distance travelled is not zero.

Say the race track is a circle of radius r meters. So the lap distance would be the circumference of the circle, which is 2πr m. So the distance travelled is 2πr m and the displacement is zero.

Hope this satisfies you :)

Assume at exactly 100.0°c and 1.00 atm total pressure, 1.00 mole of liquid water and 1.00 mole of water vapor occupy 18.80 ml an

Grace [21]

Answer 1) : When we calculate the ΔQ = -40.66 kJ (heat of vaporisation).

Then, we can relate the work done with this equation,

ΔW = -PΔV

First we need to calculate the volume, which will be,

Volume of water vapor = (nRT) / (P)

Then, V = (1 mole) X (0.0821 L X atm/mole X K) X (373.15K) / (1atm) = 30.6 liters So, it is given, and verified.

Volume of Water can be used for finding the; Density = M / V

D = ( 1 mole) X (18.02 g/mole) / (18.80 mL) = 0.9585 g/mL

On, substituting the values, we get,

ΔW = -PΔV

Work = - (1 atm) X (0.00188L - 30.62L) X 0.1013kJ/L X atm = 3.10 kJ

hence the work done is 3.10 kJ

Answer 2) Now, for calculating the internal energy, we can use the formula as,

ΔE = ΔQ + ΔW

Here, we have the values of ΔQ = -40.66 kJ and ΔW as = 3.10 kJ

So, we get, ΔE = (-40.66) + (3.10) = - 37.55 kJ

Therefore, the change in the internal energy will be -37.55 kJ.

The electron configuration of an element is 1s22s22p¹. How many valence electrons does the element have

Cloud [144]

Answer:

$\huge\boxed{\sf 3 \ electrons}$

Explanation:

<h3>Electronic configuration:</h3>

$1s^22s^22p^1$

The outermost/valence shell is the second one, seeing from the electronic configuration.

<h3>Valence electrons:</h3>

= 2 + 1 = 3 (electrons are raised to the power in the electronic configuration)

Since, the valence shell here is 2, the electrons of second shell will be counted as valence electrons.
