Answer: There are three main places where volcanoes originate: Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and. Convergent plate boundaries (subduction zones)
Explanation:
Volcanoes often form in the areas where tectonic plates make contact. The friction created between two plates by the constant movement melts the Earth's crust, causing the rock underneath the crust to turn into magma due to the great temperatures created by friction. ... Volcanoes may be formed at subduction zones
Answer:
No
Explanation:
Binary compounds contain only 2 distinct elements.
For example magnesium oxide MgO is a binary compound.
NaHCO3 contains 4 distinct elements.
Explanation:
It is given that the energy change is -162 kJ and work done is -194 kJ. As we know that formula for change in enthalpy is as follows.
dH = dE + W
where, dH = change in enthalpy
dE = change in energy
W = work done
Therefore, the change in enthalpy will be as follows.
dH = dE + W
= -162 kJ + (-194 kJ)
= -356 kJ
As the negative sign indicates heat is being released. Therefore, the reaction is exothermic in nature.
Thus, we can conclude that the change in energy of the gas mixture during the reaction is -356 kJ.
Evolution can not be tested by experiment given that it depends largely on observations that fit into a wider scope and point to a common conclusion.
<h3>Can evolution be proven empirically?</h3>
Science is know to be empirical, In science, the evidence that backs up a claim is what establishes it as true or false. Thus all theories must be tested by experiment.
However, the theory of evolution can not be tested by experiment given that it depends largely on observations that fit into a wider scope and point to a common conclusion. In other words, evolution lies “outside of empirical science”.
The fact that it can not be directly proven empirically does not necessarily make it out to be false. That was the conclusion of Paul Ehrlich in his 1967 article.
