Whether a catalyst is present or not,
Concentrations of reactants,
Temperature,
Pressure (but this is least likely to affect rate)
(1) combination reactions, (2) decompostition reactions, (3) single dicplacement reactions, (4) double displacement reactions. ur welcome peoples
The four main factors that affect aquatic ecosystems are waters depth, temperature, flow, and amount of dissolved nutrients.
Weather, Mountain Point, Distance From Equator, Location
Four factors that determine the climate of an area are distance from the sea, ocean currents, direction of prevailing winds, and the relief of the area. The proximity to the equator also plays a role in the climate of an area.
There are four basic types of chemical reactions. In this case, when sodium reacts with magnesium sulfate to form sodium sulfate plus magnesium, it is a single replacement reaction.
The products will also have one atom of S (silicon) and four of O (oxygen) because the number of atoms is not changed, only their chemical combinations.
Four factors are:- temperature- pressure- catalysts- stirring
list four possible clues to a chemical change
Temperature, atmospheric pressure (normal circumstances would be 1atm), percentage uncertainty of the equipment, loss of heat to your surroundings, parallax when reading scales such as a thermometer. And basically any variables that can be changed to be more accurate e.g your using cm's instead of mm's. Hope that helps :)
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.

Things that could speed up a chemical reaction include, temperature, nature of the reactants, catalysts, surface area, and concentration. Which of these may apply to your experiment will almost always vary depending on the type of experiment.

the four components of fire are heat, fuel, oxygen and the sustaining chemical reaction

What the heck i want me answer lol\
Abiotic Factors that affect population include:TemperatureWindMoistureSoil TypeElevationLatitudeTopography
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction
