Chromium is a metal in nature. So when one chromium is
bonded to another chromium, there is a weak intermolecular forces which helds
them together which we call as “metallic bonding”.
Metallic bonding is the intermolecular force of attraction which
exist between valence electrons and the metal atoms. It is considered as the
sharing of various detached electrons between many positive ions, whereby the
electrons serve as a "glue" which gives the substance a definite
structure.
Answer:
E = 16 J
Explanation:
We have,
You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg
It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :
Plugging all the values,
So, the maximum kinetic energy on his fastest day is 16 J.
Answer:
Explanation:
Ideal gases follow the combined law of gases:
Where,
- Pressure is the absolute pressure and its units may be in any system, as long as they are the same for both states.
- Also, volume may be in any units, as long as it they are the same for both states.
- Temperature must be absolute temperature, whose unit is Kelvin.
Your data are:
- P₁ = 1200.00 mmHg
- P₂ = 1.11842 atm
- V₁ = 85.0 mL
- V₂ = 350.0 mL
- T₂ = ?
- T₁ = 90.0ºC
<u>1. Conversion of units:</u>
- P₁ = 1200.00 mmHg × 1.00000 atm / 760.000 = 1.578947 mmHg
- T₁ = 90.00ºC + 273.15 = 363.15K
<u>2. Solution</u>
- Clearing T₂, from the combined gas equation you get:
I think they oxidize the stain
