Answer:
D.
Explanation:
You try to get 8 electron on the outermost "shell" so you have no left over or "valence" electrons.
Answer:
12
Explanation:
6 moles multiplied 2 atoms of O2
That gives 12 atoms
Answer:
Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
Explanation:
The Big Bang theory is one of the ones used most frequently nowadays to describe how the cosmos came into being.
<h3>What does big bang theory state?</h3>
According to this theory, the universe formed 13.8 billion years ago as a result of the primordial atom, a single particle, exploding and generating an unprecedented cosmic disaster. The universe is always expanding, according to the same theory.
The key supporting data for the big bang theory are:
The galaxies to getting further and distant from us. This distance is taken at high speeds. In other words, the distance between galaxies is inversely correlated with their spacing velocity. Our perception of galaxy dysthanization occurs because the universe is continually expanding, according to this data, which is known as the "Hubble Law," and this hypothesis also explains that The cosmos has already been unified.
According to the big bang theory, the cosmos was extremely hot at the time of its creation; if this is accurate, we should find some proof of this warmth. Radio astronomers discovered this proof when they noticed that microwaves with a temperature of 2,725 degrees Kelvin included cosmic background radiation. This radiation is perhaps proof of the universe's high temperature.
Last but not least, the Big Bang most likely contributed to the abundance of hydrogen and helium elements.

Answer:
The correct answer is the activation energy for the reaction is lowered.
Explanation:
Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.
Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.
Enzymes does not have any effect in the equilibrium of the reaction.
