A sodium atom contains 11 electrons and 11 protons. When the atom bonds, say to chlorine for instance, NaCl, the sodium atom will give up an electron to the chlorine. When an atom loses an electron, it becomes a positively charged ion, Na+ in this example. The chlorine gains an electron and becomes negatively charged, Cl-.

Hope that helps!

Part A What are plate boundaries at which lithospheric plates that a) move toward each other, b) move past each other, and c) mo
Alex787 [66]

Answer:

a. Convergent boundary

b. Transform boundary

c. Divergent boundary

Explanation:

Convergent boundary are boundary where tectonic plates collide with each other. This kind of boundary might involve a collision between continental and oceanic plates, continental and continental plates and oceanic and oceanic plates. Generally, convergent boundary are regions for mountainous structures . Example of mountain formed through convergence are mountain Everest and Himalayas .

Transform boundary are boundary where tectonic plates move past each other . This kind of boundary is responsible for the creation of Extensive Fault like the San Andrea Fault.

Divergent boundary are boundary where tectonic plates move away from each other.  The diverging movements brings about oceanic ridges. The mid oceanic ridges is where magma rises to the surface to form a new crust. The up welling of this magma causes further separation of this plates.

The picture above illustrate convergent, divergent and transform boundary.

#1: Which of the following statements is true?
liberstina [14]
<span>Endothermic reactions take in heat from the environment in order to react while exothermic reactions release heat during the reaction. For this, D must be true as the products have less energy because they have released heat during the reaction. A and C are incorrect because they products and reactants are equal and B is wrong because the energy of the products would be more as the reaction took in heat.</span>

Suppose you have made the following hypothesis: The greater the height from which you drop a ball, the faster the ball will be t
jek_recluse [69]

Answer:

C. A ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.

Explanation:

The statement of the hypothesis is that " the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up ".

The hypothesis statement is quite explicit. We can deduce that objects at a higher height above the ground will hit the ground much more faster and harder compared to those at a shorter height.

A ball at height of 10m is expected to drop with a higher speed on the ground compared to an identical ball at a height of 5m.

If the balls are at the same height, they are expected to fall with the same speed so far they are identical. Also, a ball at a shorter height will fall at a lower speed.
