Which event is fast change that occurs as a result of plate tectonics?

Molodets [167]

Answer: B. Volcanic eruption

Explanation:

A volcano is firmed when molten rocks is formed to the surface of the Earth. Volcanoes release molten rocks, ash, and gases to the Earth's surface.

Volcanoes are agents of change as the eruptions lead to the formation of new landforms and also destroy several things that they come in contact with.

Volcanic eruptions also occurs due to plate tectonics. Other events that happen due to plate tectonics also include earthquakes, and tsunamis.

Answer:

$p_{Cl_2}=629.25mmHg\\p_{N_2}=209.75mmHg$

Explanation:

Hello,

At first, consider the chemical reaction:

$2NCl_3-->3Cl_2+N_2$

Now, considering the ideal gas equation, we compute the total moles:

$PV=nRT\\n=\frac{PV}{RT} \\n=\frac{839mmHg*\frac{1atm}{760mmHg}*3L }{0.082\frac{atm*L}{mol*K}*359K }\\ n=0.1125mol$

Then, taking into account that the total moles are stoichiometrically handed out by the half (0.05625mol), one can say that:

$n_{Cl_2}=0.05625molNCl_3*\frac{3mol Cl_2}{2molNCl_3} =0.084375molCl_2\\n_{N_2}=0.05625molNCl_3*\frac{1mol N_2}{2molNCl_3} =0.028125molN_2$

Thus, the molar fractions are:

$x_{Cl_2}=\frac{0.084375}{0.1125} =0.75\\x_{N_2}=\frac{0.028125}{0.1125} =0.25$

Finally, the partial pressures are:

$p_{Cl_2}=x_{Cl_2}P=0.75*839mmHg=629.25mmHg\\p_{N_2}=x_{N_2}P=0.25*839mmHg=209.75mmHg$

Best regards.

Explain how genes lead to the traits that an organism has.

Genes are segments of DNA, and DNA is of course a part of fiber from your parents, so when you get that DNA, you usually inherit a few traits or hobbies from them
