Answer:

Change in plate tectonic leads to change in earth surfaces.

Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.

The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.

When aluminum, AlAl, metal is dipped in an aqueous solution of hydrochloric acid, HClHCl, hydrogen gas, H2H2, is produced with t
kifflom [539]

Answer:

Balanced equation: 2Al(s)+6HCl(aq.)\rightarrow 2AlCl_{3}(aq.)+3H_{2}(g)

Explanation:

  • Al is an metallic species with a standard reduction potential of -1.66 V( E_{Al^{3+}\mid Al}^{0}=-1.66V).
  • H_{2} is present at the intermediate position in electrochemical series with a standard reduction potential of 0 V (E_{H^{+}\mid H_{2}}^{0}=0V).
  • So, when Al is dipped in aqueous solution of HCl, Al is readily oxidized to produce Al^{3+} whereas H^{+} is reduced to H_{2} .
  • Hence, as a whole, aqueous AlCl_{3} and gaseous H_{2} is produced as products.

Balanced equation: 2Al(s)+6HCl(aq.)\rightarrow 2AlCl_{3}(aq.)+3H_{2}(g)

How much energy must be added to a 2-kg piece of wood with a specific heat
lesya692 [45]

Answer:

A. 140,800 J

Explanation:

Specific heat of a material is defined as the amount of energy required to increase in 1°C 1kg of the material. <em>For wood there are required 1760J perkg per °C.</em>

The equation is:

Q = C*m*ΔT

<em>Where Q is heat in Joules,</em>

<em>C is specific heat (1760J/kg°C),</em>

<em>m is mass (2kg)</em>

<em>ΔT is change in temperature (50°C - 10°C = 40°C)</em>

Replacing:

Q = 1760J/kg°C*2kg*40°C

Q = 140800J

Right option is:

<h3>A. 140,800 J </h3>
