Answer:

In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity

Determine the pressure change when a volume of gas at 760 mmHg is heated from 30.0 °C to 40.0 °C.
bekas [8.4K]

Answer:

<u>253.33 mmHg</u>

Explanation:

According to Charles' Law,

P₁ / T₁ = P₂ / T₂

P₁T₂ = P₂T₁

P₂ = P₁T₂ / T₁

= 760 x 40 / 30

= 760 x 4/3

= 1013.33 mmHg

Change in Pressure

= 1013.33 - 760

= <u>253.33 mmHg</u>

Heating devices can be made by passing an electric current through a conductor of:
olchik [2.2K]

Answer:

High resistance

Low conductivity

Explanation:

The more resistance (aka less conductivity) there is, the more the energy is turned into heat than simply  passing through the object.

The correct lewis structure for COH2 contains how many covalent bonds?
VARVARA [1.3K]

Answer:

Four covalent bonds.

Explanation:

Hello,

In this case, given the attached picture in which you can find the Lewis dot structure for metanal (formaldehyde) we can see two C-H bonds and two C-O bonds via a double bond, thus, we can compute the type of each bond given the electronegativities of hydrogen, carbon and oxygen which are 2.1, 2.5 and 3.5 respectively:

C-H=2.5-2.1=0.4\\C-O=3.5-2.5=1.0

Thus, since both electronegativity difference are less 1.7 we infer that all of them are covalent, therefore, it has four covalent bonds, two C-H bonds and a double C-O bond.
