Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
Enzyme-containing laundry detergents will remove stains more effectively than detergents without enzymes. Stains will be removed more successfully from clothing with homemade laundry detergent than from commercial detergents.
A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable. A person's age won't alter as a result of other circumstances like what they eat, how much they attend school, or how much television they watch. In actuality, when attempting to establish a link between two variables, you are attempting to determine whether the independent variable affects the dependent variables in any way.
A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend. A test score, for instance, maybe a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.
