Look at the reaction below.
H2SO4(aq) + Ca(OH)2(aq).
→ CaSO4(aq) + 2H2O(1)
Which substance is the base in the reaction?
2H20 (1)
H2SO4 (aq)
CaSO4 (aq)
Ca(OH)2 (aq)

Answers

Answer 1

Answer:

Ca(OH)2 (aq)

Explanation:

The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:

H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)

According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.

In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.

Answer 2

Answer:

Ca(OH)2 (aq)

Does the shadow tell you that the girl is translucent, transparent, or opaque? What inference can you make? also explain it


Subject Science​

Answers

Answer: Well, shadows are visible to us because they are darker than the light around them. When an object is translucent it allows a lot of light to pass through. This amount of light makes the shadow very light and similar in color to the original light source.Why do translucent and opaque materials form shadow? Answer: Translucent and opaque materials form shadow because translucent objects block some light and opaque object block the light completely.A shadow appears the side of the objects furthest from the light source. * An opaque material makes a dark shadow. * A translucent material makes a faint shadow. * A transparent material cannot make any shadow. so it translucent

Do you believe that most of the resources we have on Earth are
limited or unlimited?
There are limits to everything; at this rate, we'll run out of all our
resources.
Resources may not all be limited, but shortages will severely

Resources such as fossil fuels may be limited, but we'll
eventually switch to renewable ones.
Resources are essentially unlimited; we'll use technology to
overcome any shortages.

Answers

I believe that resources on earth that are limited. studies of shown that helium has been very low. Yes we might have a lot of somethings but come time we might run out of those resources. And yes when that happens we might be able to make synthetic materials so we could possibly overcome any shortages. So I guess that answer just remains up to time and the future generations.

Potential Energy on the way up the rollercoaster

Answers

Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
