All the answers are correct
Explanation:
Just did the Edge question and got it all correct
Answer: Heyya, the answer is 0.8539gH2. Pls mark brainliest
Explanation:
Answer:
a) dispersion forces, dipole-dipole forces, hydrogen bonds
b) dispersion forces
c) ion-ion interparticle forces, hydrogen bonds, dipole-dipole forces
d) metallic bonds
Explanation:
The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles(Chem Purdue). Dipole forces exists in all molecules but not in metals.
The intermolecular forces present in each substance must be broken before the stated process can occur.
The nature of intermolecular forces in each substance has been shown in the answer section.
For ammonia, the dispersion forces, dipole-dipole forces and hydrogen bonds must be degraded before liquid ammonia begins to boil.
For solid phosphorus which is non polar, only dispersion forces needs to be broken.
To dissolve CsI in HF, ion-ion interparticle forces of CsI must be broken while the dipole-dipole forces, dispersion forces and hydrogen bonds between HF molecules must be broken.
Potassium metal is a pure metal hence only metallic bonds must be broken in order to melt the solid.
Ethylene, also named ethene.

<h3><u>Answer;</u></h3>
C. increasing the surface area of Fe2O3
<h3><u>Explanation;</u></h3>
- The rate of reaction refers to the speed at which products are formed from reactants.
- The rate of any chemical reaction depends on a number of factors which include, surface area, temperature, concentration of reactants among others.
- <em><u>When solids and liquids react, increasing the surface area of the solid will increase the rate of reaction. Thus, decrease in the size of particles causes an increase in the total surface area of the solid and therefore increasing the rate of reaction.</u></em>
