Dafna1 [17]

Answer:

The last option

Explanation:

The Bohr model was an attempt to explain atomic hydrogen's spectrum. This was done by establishing energy levels of separate electron orbits in the atom.Thos model was followed by the Schrödinger model.

If an object is accelerating at a rate of 25 m/s2, how long (in seconds) will it take to reach a speed of 550 m/s? (Assume an in
V125BC [204]

Answer:

22s

Explanation:

Given parameters:

Acceleration  = 25m/s²

Final velocity = 550m/s

Initial velocity  = 0m/s

Unknown:

Time taken  = ?

Solution:

To solve this problem, we are going to use one of the motion equations:

                 v  = u + at

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

                  550 = 0 + 25 x t

                  550  = 25t

                    t  = 22s

Methane (CH4) is a gas that is found in small quantities in earths atmosphere. which type of bonds does methane have and why doe
OLga [1]

Answer:

Methane is a covalent bond. Methane is a chemical compound from the bonding  one carbon atom and for hydrogen atoms. Although electronegativity increases as you go right of the periodic table, hydrogen has an electronegativity of 2.20. Chlorine has an electronegativity of 2.55. There difference in electron negativity (0.34). Therefore it is a non polar compound. If there difference was much greater, than they would form a ionic bond. Alkali metals tend to form the most ionic bond, but although hyrdogen is placed with them, it has a higher electronegativity so hydrogen is an exception.

Carbon has 4 valence electrons so it will want to gain 4 more electrons to become stable (Octet rule). Hydrogen has 1 valence electron, so it will want to lose it to become stable. Therefore, one carbon atom takes 1 electrons from 4 hydrogen atoms.
