The atoms under this question can be found elsewhere and as follows:
chlorine (Cl) - 3.61
sulfur (S) - 2.58
hydrogen (H) - 2.2
oxygen (O)- 3.44
<span>fluorine (F)- 4
</span>
<span>Based on difference in electronegativities between atoms, the most polar bond pair would be hydrogen and fluorine. They have the highest electronegativity difference.</span>
Answer:
C. Ball A is the densest because it sank to the bottom of the liquid.
Answer:
Energy absorbed by <u>Iron block</u> E (iron) = 460.5 J
Energy absorbed by <u>Copper block</u> E (Copper) = 376.8 J
Explanation:
To find the heat absorbed, we can use the formula as,
<em>q = m c ΔT</em>
Here, Mass = m = 10 g = 0.01 kg
ΔT = change in temperature = 400 - 300 = 100 K = 100 - 273 = -173 °C
c = specific heat capacity
c for iron = 460.5 J/kg K
c for copper = 376.8 J/kg K
Plugin the values in the above equation, we will get,
<em>q (iron) = 0.01 kg × 460.5 J/kg K × 100 K = 460.5 J</em>
<em>q (copper) = 0.01 kg × 376.8 J/kg K × 100 K = 376.8 J</em>
Answer:
A. Solids can only change shape if forced to make a change
Explanation:
A solid substance is one of the states of matter.
Matter is anything that has weight and occupies a definite space.
There are three states of matter commonly known: solids, liquids and gases.
- Solids have a fixed shape and definite volume.
- Their crystals are well ordered about a fixed point.
- It is only when a force is applied that their well ordered arrangement is destroyed and they are forced to make a change.
