Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
Answer:
There are three nuclei and one lone pair, so the molecular geometry is trigonal pyramidal.
Explanation:
Answer:
Explanation:
To identify the different variables from this experiment, we must first understand what the different types of variables depicts.
Independent variables are those variables that do not rely on the conditions of the experiment. They are what causes the experiment to proceed the way we want.
Dependent variables are the variables that relies on the effect of the independent variables. They are what we are actually testing for.
Controlled variable are the variables that are constant in an experiment and their outcomes are used to checkmate an experiment.
In the experiment by Justin:
Independent variable: water, coffee, milk
dependent variable: garden growth
controlled variabe: fertilizer
When the overall charge is equal to zero
