yes and no gold is super dense but malleable lead is dense but brittle so no.
This is the answer hope it helps you!!
Given:
64.82 g of aluminum
metal
100.0oC is cooled
to 82.0 °C
specific heat of
aluminum is 0.897 J /g °C.
Required:
Change in heat
energy
Solution:
This can be solved
through the equation H = mCpT
where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
The specific heat
of the water is 4.18 J/g-K
Plugging in the
values into the equation
H = mCpT
H = (64.82) (0.897
J /g °C) (82 – 100)
H = -1,046.6 J
Bromine has 45 of neutrons
Answer:
14 g.
Explanation:
- From the figure attached:
<em>the solubility of lead(II) nitrate, Pb(NO₃)₂, in 100 grams of water has a temperature of 30ºC is </em><em>(66 g).</em>
When beaker containing 80 grams of lead(II) nitrate, Pb(NO₃)₂, in 100 grams of water has a temperature of 30ºC.
<em>∴ The grams of the salt are undissolved, on the bottom of the beaker are </em><em>(14 g).</em>
