The symbol for hydrogen is H
Silver. For the most part only metals can have metallic bonding. Ammonium chloride has ionic bonding (poly-atomic cation + nonmetal=ionic bonding), iodine is a diatomic element so it will form a covalent bond with itself, and barium oxide has ionic bonding (metal+nonmetal or metal+poly-atomic anion=ionic bonding).
I hope this helps. Let me know in the comments if anything is unclear.
Answer:
Specific heat of ethyl chloride in gas and liquid phases, enthalpy of vaporization and specific heat of solid surface.
Explanation:
In order to determine the final temperature, the heat lost by the chloride needs to be found. This would require the specific heat in both phases and the enthalpy of vaporization. (you will use q=mc(delta)T and q=m(delta)H)
Then the energy gained by the surface needs to be found. This will require the specific heat in order to use the q=mc(delta)T equation.
The inverse proportion is PV = k
We can write the equation as <em>P</em> = k/<em>V</em> or <em>P</em> ∝ 1/<em>V</em>. Thus, <em>P</em> and <em>V</em> are <em>inversely related</em>.
We can rewrite <em>V</em>= T/k as <em>V</em> = k<em>T</em> or <em>V</em> ∝ <em>T</em>. Thus,<em> V</em> is <em>directly proportiona</em>l to <em>T</em>
.
<em>F</em> = -k<em>x</em>² is <em>neither a direct nor an invers</em>e relation.
<em>y</em> = k<em>x</em> – 8 is a linear relation, but it is <em>not a direct proportion</em> because of the “-8” term.
Answer:
Percent error = 5.6%
Explanation:
Given data:
Measured value of density by students = 2.85 g/cm³
Accepted density of aluminium = 2.70 g/cm³
Percent error = ?
Solution:
Formula:
Percent error = [ Measured value - accepted value / accepted value ]× 100
Now we will put the values in formula:
Percent error = [ 2.85 g/cm³ - 2.70 g/cm³ / 2.70 g/cm³ ]× 100
Percent error = [0.15/2.70 g/cm³ ] × 100
Percent error = 0.056× 100
Percent error = 5.6%
