Answer:
the chemical formula for butane is C4H10
Answer:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
Explanation:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
For example: "mono" indicates 1 atom, "di" indicates two atoms, "Hexa" indicates 6 atoms, "octa" indicates eight atoms.
When naming binary ionic compounds, the cation is named first, then the nonmetal anion is named.
Answer:
221 °C
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 4.1 L
Initial temperature (T₁) = 25 °C
= 25 °C + 273
= 298 K
Final volume (V₂) = 6.8 L
Final temperature (T₂) =?
The final temperature of the gas can be obtained as follow:
V₁ / T₁ = V₂ / T₂
4.1 / 298 = 6.8 / T₂
Cross multiply
4.1 × T₂ = 298 × 6.8
4.1 × T₂ = 2026.4
Divide both side by 4.1
T₂ = 2026.4 / 4.1
T₂ ≈ 494 K
Finally, we shall convert 494 K to celcius temperature. This can be obtained as follow:
°C = K – 273
K = 494
°C = 494 – 273
°C = 221 °C
Thus the final temperature of the gas is 221 °C
It is false, because models don't help you get a better understanding of the world, they help you better understand what you are trying to get from it like a weather model, it helps us see the weather because it is a visual so people would know what type of weather is where.
Answer:
C. Among the metals
Explanation:
The best place to look for this element that has this property is among the metals.
The ability of a metal to be malleable and possibly drawn to a sheet is a manifestation of their metallic bonding. Metallic bonds are very predominant among metals and their alloys.
This bond type determines the bulk of the physical properties of metals.
One of such is their ability to drawn into thin sheet, it is called malleability.
