Answer:
no
Explanation:
the ocean has salt water which isn't good for you
Either 60:50 or 6:5
because anna has 50 and alissa has ten more than anna so alisa would have 60.
The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

The kinetic energy that the given object will have is: 10 J
<h3>Kinetic Energy Calculation</h3>
We are given;
Mass of object; m = 4 kg
Speed of object; v = 5 m/s
Now, the formula for kinetic energy is;
K.E = ½mv²
Plugging in the relevant values gives;
K.E = ½ × 4 × 5
K.E = 10 J
