The continental crust, or the crust that lies beneath the continents, usually ranges from around 30 to 45 kilometers thick. These thicknesses are found on most continents and are dependent on height above sea level and mountainous regions. Although there are rare areas that exceed 70 kilometers thick, according to the United States Geological Survey, or USGS, less than 10 percent of the total area of the Earth's crust exceeds 50 kilometers thick.

Thicknesses below 30 kilometers are typically only found under the ocean and are called oceanic crust. The thinnest sections of the crust are only approximately five kilometers thick, which is a small fraction of the thickness of the thickest parts of the continental crust. The thickness of oceanic crust is difficult to estimate by looking only at proximity to continents or latitude since the crust varies greatly from coast to coast and everywhere in between. For example, along the eastern coast of the United States, the oceanic crust ranges from 10 to 30 kilometers thick, according to the USGS.

A 25 gram(m) metal ball is heated to 200C(delta T) with 2330 Joules(q) of energy. What is the specific heat of the metal?
Dominik [7]

Answer:

The specific heat of the metal is 0.466 \frac{J}{g*C}

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

The equation that allows calculating heat exchanges is:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

  • Q= 2330 J
  • c= ?
  • m= 25 g
  • ΔT= 200 °C

Replacing:

2330 J= c*25 g* 200 °C

Solving:

c=\frac{2330 J}{25 g* 200 C}

c=0.466 \frac{J}{g*C}

<u><em>The specific heat of the metal is 0.466 </em></u>\frac{J}{g*C}<u><em></em></u>

What type of energy is stored in the chemical bonds between atoms?
Brrunno [24]

Answer:

Chemical energy

Explanation:

An atom is the basic unit of a chemical element.

A chemical bond held together with atoms, ions, or molecules that leads to the formation of chemical compounds. A chemical bond may be covalent, polar covalent, or ionic. Among these chemical bonds, an ionic bond is the strongest chemical bond.

Chemical energy is stored in the chemical bonds between atoms.

Calculate the volume of a balloon that can hold 113.4 g of nitrogen dioxide, NO2 gas at STP-
Karolina [17]

Answer:

55.18 L

Explanation:

First we convert 113.4 g of NO₂ into moles, using its molar mass:

  • 113.4 g ÷ 46 g/mol = 2.465 mol

Then we<u> use the PV=nRT formula</u>, where:

  • P = 1atm & T = 273K (This means STP)
  • n = 2.465 mol
  • R = 0.082 atm·L·mol⁻¹·K⁻¹
  • V = ?

Input the data:

  • 1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K

And <u>solve for V</u>:

  • V = 55.18 L
