Answer:
0.5m/s²
Explanation:
Given parameters:
Mass to be pushed = 300kg
Force = 150N
Unknown:
Acceleration = ?
Solution:
To solve this problem, we need to apply newtons second law of motion which is expressed below:
F = m a
F is the force
m is the mass
a is the acceleration
150 = 300 x a
a = 0.5m/s²
Fusion reaction is a type of nuclear reaction where two or more nuclei combine or collide to form an element with a higher atomic number. This happens when the collision is in a very high speed. In this process, some of the matter of the fusing nuclei is converted to photons.
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
The correct answer is that anodization can produce a thin film around the metals, preventing rusting and other kinds of corrosion.
Anodizing refers to an electrolytic passivation procedure used to enhance the thickness of the natural oxide layer on the metal parts surface. The procedure is known as anodizing as the section to be treated produces the anode electrode of an electrolyte cell. The process enhances resistance to corrosion and rusting.
Answer:
When breaking a chemical bond, energy is absorbed by the chemical bond.
Explanation:
Chemical bonds are the forces of attraction that joins two chemical species. There are two types of chemical bonds: Strong Primary and Weak Secondary bonds.
When a chemical bond is formed between two species, it is accompanied by the release of energy. Therefore, <em>bond formation is an exothermic process</em>.
<u>However, energy is always required to break a chemical bond. As energy is needed to overcome the attractive forces present between the two species.</u> Therefore, <em>bond dissociation is an endothermic process.</em>
<u><em>Therefore, during bond dissociation, energy is absorbed by the chemical bond.</em></u>
