What is the mass of the light bulb? a. 425.6 g b. 204.6 g c. 240.56 g d. 245.64 g
VMariaS [17]

245.64 g is the mass of the light bulb.

<h3>What is mass ?</h3>

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

  • For a body, mass is constant. Mass can be calculated using the formula: mass = volume density. A mass's weight is a measurement of the gravitational force at work on it. The kilogram is the SI unit of mass.
  • The mass of the substance will therefore be calculated as follows: MASS OF A SUBSTANCE = VOLUME DENSITY.

So finally we can say that the mass of the light bulb and paperclips together is 245.64 g.

In completing a Fischer Esterification experiment using acetic acid and unknown alcohol catalyzed by sulfuric acid a student sta
masha68 [24]

Answer:

The equilibrium law

Explanation:

According to the equilibrium law , when $\text{concentration}$ of any of the  reactants or the products in the reaction at an equilibrium state,  is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of

Acetic acid (in excess) + $\text{alcohol}$ ⇄  $\text{ester}$ + water

$\text{Fischer esterification}$ is a reaction which involves the equilibrium. So to force the reaction towards the side of $\text{ester}$, one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.

Read the lab procedure for a controlled experiment that looks at the effect of heat on the circumference of bicycle tires.
gavmur [86]

The last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).

<h3>What is an experiment?</h3>

The essence of an experiment is to be able to establish a cause and effect relationship. It is only when we carry out a carefully controlled experiment that we can say that x causes y because the data would support our findings.

After, we have carried out an experiment, the next step is to put the evidences together and then try to arrive at a logical conclusion for the experimental procedure.

Thus the last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
