Giselle is working with a chemical substance in a laboratory. She observes that when the chemical is heated, it gives off a gas.
Phoenix [80]

The correct answer is option B, that is, hypothesis.  

A hypothesis refers to an anticipated illustration for an occurrence. It refers to a proposed illustration or a supposition made on the groundwork of inadequate proof as an initiation point for further investigation. In order for a hypothesis to be a scientific hypothesis, the scientific method needs that one can examine it.

What is mb for CH3NH2….
drek231 [11]

Answer:

A.) K_b = \frac{[CH_3NH_3^+][OH^-]}{[CH_3NH_2]}

Explanation:

The general Kb expression is:

K_b = \frac{[HA][OH^-]}{[A^-]}

In this equation

-----> Kb = equilibrium constant

-----> [HA] = acid

-----> [A⁻] = base

Since liquids are not included in equilibrium expressions, H₂O should not be present. The products are in the numerator while the reactant are in the denominator. In this reaction, CH₃NH₂ is acting as a base and CH₃NH₃⁺ is acting as an acid.

As such, the expression is:

K_b = \frac{[CH_3NH_3^+][OH^-]}{[CH_3NH_2]}

Does the bowling ball have more potential energy or kinetic energy just before it hits the ground? Why?
AnnZ [28]

Answer:

Equal

Explanation:

When the bowling ball is first dropped, it has a maximum potential energy but minimum kinetic energy.  The height is max, so the potential energy will be greatest.  Velocity is 0, so kinetic energy will be 0.
