Answer:This is a very interesting question. I think of it like this. You have a piece off ice floating in the water. Let's say a portion off. It is submerged. No. If this the portion off the sub marched portion has a volume be, it means that the buoyant force will be times the density off water times G. Now this will be equal to the point force, which is equal to the weight off the ice block. Now, once I this ice turns into water, it will still have the same rate. But now its density will be equal to that of water. So it's wait will be saying mass times G. Now you can cancel T on mass is equal to three times rope. Now, this week is this volume and if you notice, row is also the density of water, which means this mass of water contains will help this volume. It means once the ice becomes water, it perfectly fits into this volume, which means the water level's stays exactly the same. It's almost magical, but what happens if there isn't a butt in a bubble? You can think off it in a slightly mathematical way, If you have an air bubble in on Ice Cube, it's total density. Its average density will be less than the density off ice, but an easier way to think about it is like this. You have a piece off ice, which has in a bubble in it on dhe, obviously that it's water here and now. Once the ice melt, the amount of water displaced will be. The volume of the water displaced will equal the weight off the ice. So the what? The water in the ice, if it's exactly in this volume, so it must still be the same. But the answer will be different if you have a great off sandal. If you have a grain of sand, let's say somewhere over here the total density off the ice cube will be larger. The average density on once the ice melt the sand simply false down, which means this ice this piece off ice was further down than it for the lower in the water than it would have been if it was simply made off ice. So to make up for that, when the ice melts, the amount off the volume off the water will be less than the amount of water displaced, so the level of water will decrease if it were if there were a grain of sand in the ice, so you would expect that the water level would tries if, uh, in the case off the air bubble. But it's the identity of baby. It is so small that it simply doesn't count.

Accuracy is the degree of closeness to true value.

Precision is the degree to which an instrument or process will repeat the same value.

Hope it helps....

Answer:

Accuracy and precision are alike only in the fact that they both refer to the quality of measurement, but they are very different indicators of measurement. Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value

The emission lines of an element is characteristics of the element and can be thought of like a fingerprint for elements. Emission spectra is used to identify the elements.

The electromagnetic radiation spectrum produced when an electron changes from a high energy state to a lower energy state is known as the emission spectrum of a chemical element or chemical compound.

The energy difference between the two states is equal to the photon energy of the emitted photon. Each atom contains a large number of potential electron transitions, and each transition has a distinct energy difference.

An emission spectrum is made up of a variety of transitions that result in various radiated wavelengths. The emission spectra of each element is distinct. Therefore, option d is correct.

The volume, in liters, per kg of the Himalayan pink salt would be 0.97 L

Recall that: density = mass/volume

Hence: volume = mass/density

In this case, the density of the Himalayan pink salt is 1.03 while the mass we are working with is 1 kg.

1 kg is equivalent to 1000 g

Thus: volume = 1000/1.03

                           = 970.87 mL

Divide by 1000 to convert to L

                        970.87/1000 = 0.97 L

Explanation:

The mass of KOH reacted is 2.576 g. To have a 10% excess KOH, i need 2.833 g of KOH.

The equation of the reaction is;

2 Al(s) + 2 KOH(aq) + 6H20 (l) --------> 2K+ (aq) + 2 Al(OH)4^- (aq) + 3H2(g)

We are told that 1.25 g of Al was used in the reaction, hence;

Number of moles of Al = 1.25 g/27 g/mol = 0.046 moles

To obtain the amount of KOH required for the reaction;

2 moles of Al reacts with 2 moles of KOH

0.046 moles of Al also reacts with 0.046 moles of KOH

Mass of KOH reacted = 0.046 moles of KOH × 56 g/mol = 2.576 g

To have a 10% excess KOH;

Let the needed mass of KOH be x

x =2.576 g + (0.1 × 2.576 g)
