Answer:A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. ... Transits of Venus are among the rarest of predictable astronomical phenomena.
Explanation:
Animals would lose their habitat, pollution would increase in the area and the surrounding ground would become dirtier due to fluids from vehicles.
Answer:
mNaCl = mNa + mCl
mNa = 20g
mCl = mCl2/2 = 30/2 = 15g
mNaCl= 20+15 = 35g
Answer:
Exothermic reaction
Explanation:
Notice that the energy component is located on the right side of the reaction. The right side is always known as the product side. Whenever energy is located there, the reaction is known to give off energy - essentially, we can say that energy is a product, as well. Reactions that give off energy are known as exothermic reactions.
On the other hand, if the energy component was located on the left side, or reactant side, of the equation, it would be known as an endothermic reaction.
Here, it's exothermic.
Hope this helps!
