Answer:
extensive hydrogen bonding
Explanation:
The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.
Hope this helps :)
Answer:
Chemical energy.
Explanation:
This is biology btw, not chemistry
Answer:
Explanation:
Mole ratio
Moles of CO₂
Use formula to find mass
Relative molecular mass of CO₂ = 12 + 16 × 2 = 44
Combustion reactions release energy in the form of heat.
Hope this helps and tell me if you need more help!
You just need to multiply the total mass by the decimal value of the part that is tin. 133.8*0.103=13.8g (following the rules of significant figures).
