There are three which are:
dispersion/london/van der vaals forces
dipole/dipole
hydrogen bonding
Answer:
a. Decomposition.
Explanation:
A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.
- Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
- A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
- A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Hence, the answer is a decomposition reaction.
Answer:
Global warming is expected to cause changes in the amount of cloud cover, and the height and thickness of these clouds in the future, shifting the balance between the parasol and blanket effects of clouds. The knock-on effect this will have on temperature is known as cloud feedback

Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of 
kg and the mass of bacterium is on order of 
kg
Answer:
The total numbers of atom in bacterium are 
.
Explanation:
Mass of hydrogen atom, m= 
kg
Mass of bacterium , M= kg
Mass of bacterium atom =m'
Given ; 
let the number of atoms in bacterium be N
The total numbers of atom in bacterium are .
The amount of heat (in calories) needed to raise the temperature is 324.885 calories
<h3>How to determine the temperature change </h3>
We'll begin by obtaining the temperature change. This can be obtained as followed:
- Initial temperature (T₁) = 14 °C
- Final temperature (T₂) = 25 °C
- Change in temperature (ΔT) = ?
ΔT = T₂ - T₁
ΔT = 25 - 14
ΔT = 11 °C
<h3>How to determine the heat (in Calories)</h3>
The amount of heat needed to raise the temperature can bee obtaimedals follow:
- Mass (M) = 33 g
- Change in temperature (ΔT) = 11 °C
- Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
- Heat (Q) =?
Q = MCΔT
Q = 33 × 0.895 × 11
Q = 324.885 calories
Thus, the amount of heat needed is 324.885 calories
