We can calculate the density of the balloon as follows:
Therefore, the balloon will fall
Since the density of air is about 0.00123 g/cm^3 , the balloon is much more dense than the surrounding air. As a result, the balloon weighs more than the air that it displaces so the balloon will fall.
Answer:
Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure. In fact, if they are going to form ions, Group 14 elements form positive ions. Carbon and silicon form covalent bonds. Carbon's millions of organic compounds are all based on shared electrons in covalent bonds.
Explanation:
Force = mass*acceleration so
3.6*2.5 =9 Newtons
Research has shown that the electrons orbit the nucleus in circular motions as shown on the classic Bohr model. FALSE
Answer: C. Both observation 1 and observation 2
Explanation: A geocentric model shows the stars and the sun and where they move to.
