When a piece of metal A is placed in a solution containing ions of metal B, metal B plates out on the piece of A.(c) Which metal

would you use as the anode in a voltaic cell incorporating these two metals?

Zinc is no longer the positive electrode because copper has a more positive (higher) value than zinc (anode). The anode value is reduced by the potential of the other electrode.

<h3>In a galvanic cell, is the anode positive or negative?</h3>

In a galvanic (voltaic) cell, the cathode is regarded as positive and the anode as negative. This seems reasonable given that the cathode is where electrons flow from the anode, which is where they originate.

<h3>What is a galvanic cell?</h3>

An electrochemical cell called a galvanic cell or voltaic cell, respectively named after the scientists Luigi Galvani and Alessandro Volta produces an electric current by spontaneous oxidation-reduction reactions. A typical device typically consists of two distinct metals that are submerged in separate beakers that each contains their own metal ions in solution and are either connected by a salt bridge or divided by a porous membrane.

Find the number of cations present in 7g of sodium prosphate Na=23 g/mol O=16g/mol P=31g/mol​
Snowcat [4.5K]

Answer:    This contains magnesium, Mg2+, and hydroxide, OH–

, ions. Each magnesium ion is +2 and

each hydroxide ion is -1: two -1 ions are needed for one +2 ion, and the formula for magnesium

hydroxide is Mg(OH)2. The (OH)2 indicates there are two OH–

ions. In a formula unit of

Mg(OH)2, there are one magnesium ion and two hydroxide ions; or one magnesium, two

oxygen, and two hydrogen atoms. The subscript multiplies everything in ( )

hope that helped!!

Identify the major attractive force in HF molecules.A) London Dispersion Forces (LDFs)
Llana [10]

Answer:

C) hydrogen bonding

Explanation:

All atoms and molecules have London Dispersion Forces between them, but they are usually overshadowed but the much stronger forces. In this scenario the major attractive force in HF molecules are hydrogen bonds. Hydrogen bonds are electrostatic forces of attraction found when Hydrogen is bonded to a more electronegative atom such as Oxygen, Chlorine and Fluorine.

Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric. (Site 2)
gogolik [260]

Filter flasks are also known as vacuum, suction or the Buchner flasks. They have thick walls and also have a short glass tube. The thick walls are designed to enable the filter withstand high pressures of vacuum applied to filter substances. Generally this is used for filtering.

While the Erlenmeyer flask also called as a conical flask, is a titration flask which consists of a conical body, a flat bottom, and round neck. This is used for used for general uses such as mixing, titrations, preparation of cultures, for recrystallization, and for supporting filter funnels.

<span>Lastly, the Volumetric flasks are graduated flasks which having markings for different volumes. They are calibrated accurately for a specific amount of liquid that can be contained in it hence this is specially used for storing precise amounts of liquid. </span>

Explain why scientists find the particulate matter of theory useful
BARSIC [14]

This idea has historical significance. The ancient Greek philosopher Democritus (born 460 BCE), who held that everything is composed of small particles moving in empty space, is credited with developing the first hypothesis we have about the microscopic universe. He had some concrete proof for this, such the fact that items like a new loaf of bread or a rose may give off a scent even when they are far from the source. Being a materialist, he thought that these odors originated from actual material particles released by the bread or the rose, rather than being purely a type of magic. He reasoned that these particles must float through the air, with some of them maybe landing in your nose where you can smell them immediately. This still makes sense in modern times. But many of us now have quite different perspectives on these "particles."

Thank you,

Eddie
