Answer:

Of course, technician B is the smarter one!    

                           

Explanation:

Water molecules attract each other, and the oil molecules also stick together. That causes oil and water to form two separate layers.

Because water molecules are denser than oil, they sink to the bottom, leaving oil sitting on top of the water.

Now, many fuel systems are designed in such a way that the suction pipe is located at the base of the tank. Given the above, it is very easy to see why water to a great degree of probability will be drawn into the system when the fuel level is low.

Cheers!

A student has a large number of coins of different diameters, all made by the same metal. She wishes to find the density of the
Elenna [48]

Answer:

A. In a graduated cylinder, put some quantity of water and measure the initial volume. Then put a coin and measure the volume. To find the volume of the coin, simply subtract the initial volume (water only) from the ending volume (water + coin). To measure the mass, take a dry coin and place it on an electronic scale. Density = mass / volume, so divide the mass by the volume to calculate the density of the coin.

B. When measuring the volume, make sure to look at the graduated cylinder at eye level and read from the bottom of the meniscus.

1. a. FeS + 2HCl --> FeCl2 + H2S
    b. This is a double- replacement reaction. (The elements "switch partners".)

2. a.2Na + F2 --> 2NaF
    b. This is a composition/synthesis reaction. (The two reactants are combining or synthesizing to make one product.)

3. a. 2HgO --> 2Hg + O2
    b. This is a decomposition reaction. (The single reactant is breaking down or "decomposing" into multiple reactants.)

4. Hydrogen gas reacts with oxygen gas to create water in a composition/synthesis reaction.

I hope these answers will help you! If you need any explanation, ask and hopefully I can get back to you. ;)

irinina [24]

Answer:

Cl

Explanation:

chlorine (2,8,7) is a non metal with highest electronegativity. Hence, it is most likely to form a negative ion with charge −1.

I hope it helps you
