The model below shows the equation that represents how hydrogen and oxygen combine to form water 2H2 + O2 —> 2H2O
Read each statement below and select all that apply to the equation.

The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product.
The law of conservation of matter is not applied in this equation.
The mass of the reactants is equal to the mass of the products in the reaction.

The total number of each type of atom is conserved in the equation.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Which of the following is most likely true about water in chemical systems? a) water dissolves nonpolar ionic compounds. b) water dissociates ionic compounds. c) water dissociates covalent molecules. d) water dissolves nonpolar covalent substances.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
