Answer:False
Explanation:
Kinda of a opinionated question, but unless you call -12 C warm then the answer is False
Answer:
nonpolar
Explanation:
A nonpolar solvent has the highest solubility with a <u>nonpolar</u> solute.
Answer:
3.2 × 10³ J
Explanation:
Step 1: Given data
- Mass of the gold ring (m): 25 g
- Specific heat capacity of gold (Cp): 0.129 J/g.°C
- Initial temperature: 75 °C
- Final temperature: 1064 °C
Step 2: Calculate the temperature change (ΔT)
ΔT = 1064 °C - 75 °C = 989 °C
Step 3: Calculate the energy required (Q)
We will use the following expression.
Q = Cp × m × ΔT
Q = 0.129 J/g.°C × 25 g × 989 °C
Q = 3.2 × 10³ J
Answer:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
