What does it mean if you are a guy and have a boyfriend

What do you mean "what does it mean"? It doesn't "mean" anything, it's just a fact.

What is meant by the rate of reaction

The rate of reaction refers to the speed at which a reaction proceeds.

Answer this question… Which of the following best describes a neutralization reaction? A. Acid + base H+ + OH- B. Acid + base salt + water C. Acid + base metal + nonmetal D. Acid + base H2O + H3O+

Does an isosceles trapezoid have one pair of congruent opposite sides and congruent base angles

Yes, an isosceles trapezoid has one pair of congruent opposite sides and congruent base angles

What information does an equilibrium constant give about a reaction

It tells whether products or reactants are favored at equilibrium

What causes the reaction rate to decrease as the reaction progresses

The concentration of the reactants decreases.

How does the phase of water affect its specific heat capacity

Liquid water has the highest specific heat capacity.

How does increasing the temperature affect a reaction

Increasing temperature affects a reaction in two ways:

1) at higher temperatures the molecules are moving around faster and collisions and reactions are more frequent, so the reaction - both forward and reverse - speed up.

2) at higher temperatures, the equilibrium state will shift. In some cases it will shift the equilibrium towards the product. In other cases, it will shift it back towards the reactants.

Kb = 1.8 x 10-5 (apple x)

What does it mean if Keq is less than 1
