How many neutrons does element X have if its atomic number is 39 and its mass number is 79?
bazaltina [42]

Number of neutrons: atomic mass - atomic number

Element X's atomic mass is 79 and its atomic number is 39. Subtract 39 from 79 to find how many neutrons Element X has.

79 - 39 = 40

Element X has 40 neutrons.

In which reaction are the atoms of elements rearranged?
NNADVOKAT [17]

Answer:

D. Hydrogen combines with oxygen to form water.

Explanation:

Hydrogen combining with oxygen to form water is a typical example of chemical reaction.

During a chemical reaction, atoms of elements are rearranged. Most chemical reactions obey the law of conservation of mass which states that "matter is neither created nor destroyed in a chemical reaction but atoms are simply rearranged".

The other choices given are nuclear reactions. In such reactions, atoms are not rearranged but are simply destroyed and made in the process.

A tennis ball is thrown horizontally at a speed of 10 m/s from the top of a building 78.4 meters high. how long does it take the
cupoosta [38]
When it comes to horizontal projectiles, the formula for time is:

t =  \sqrt{ \frac{2dy}{g} }

Where:
dy = vertical distance or height
g = acceleration due to gravity
t = time

Based on the problem, we know that the height at which the tennis ball was thrown is 78.4 m and the acceleration due to gravity is a constant 9.8m/s2. All you need to do is input that into our equation:
t = \sqrt{ \frac{2dy}{g} }
t = \sqrt{ \frac{(2)(78.4m)}{9.8m/s^{2}} }
t = \sqrt{ \frac{156.8m}{9.8m/s^{2}} }
t = \sqrt{16s^{2}}
t = 4s

The time it would take is 4 seconds.
