Answer:

Hence, C5H12 is called pentane, C6H14 is called hexane, C7H16 is called heptane and so forth. Straight-chain alkanes are sometimes indicated by the prefix n- (for normal) to distinguish them from branched-chain alkanes having the same number of carbon atoms.

The density of liquid mercury is 13.6 g/mL. What is the mass of a 175 mL sample of mercury?​

Answers

Answer:

The answer is

2380 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density of mercury = 13.6 g/mL

volume = 175 mL

The mass of the metal is

mass = 13.6 × 175

We have the final answer as

2380 g

Hail is an example of which type of phase change?
A) Sublimation
B) Evaporation
C) Condensation
D) Freezing

Answers

Answer:

D) freezing

Explanation:Because hail sounds like it is hard and hail comes down and it hurts because it is freezing.

The hail can be defined as the conversion of the water to the ice. Thus, hail is an example of freezing.

What is phase change?

The phase can be defined as the state of the matter. With the change in the temperature and the pressure values, the state of the matter, or the phase changes.

The hail has been the solid precipitation of the rain water. With the lowering of the temperature to the critical pressure, the water converts to ice.

The conversion of water to ice has been termed as freezing, Thus, hail is an example of freezing. Hence, option D is correct.

The chemical symbol for silver oxide, an ionic compound used to make button batteries, is made of silver and
oxygen and has a chemical formula of Ag20.




Answer 2 and 1

Answers

Answer:

2 Silver Ions

1 Oxygen Ion

Explanation:

Edg2021

The chemical symbol for silver oxide is not Ag₂0. The correct chemical formula for silver oxide is Ag₂O.

Silver oxide (Ag₂O) is an ionic compound composed of silver ions (Ag⁺) and oxide ions (O₂⁻). It is commonly used in button batteries as a cathode material. In this compound, two silver ions combine with one oxide ion to form a stable structure.

The chemical formula Ag₂O indicates that there are two silver ions (Ag⁺) and one oxide ion (O₂⁻) in each formula unit of silver oxide. The subscript 2 after Ag indicates that there are two Ag⁺ ions present, while the absence of a subscript after O indicates that there is one O₂⁻ ion.

Hence, the chemical formulae are discussed above.

What is the main cause of global convection currents?​

Answers

Answer:

The main cause of global convection currents is the uneven heating of the earth by the sun. Hope this helped! :)

The main cause of global convection current is differential heating, that is the temperature difference in different levels of  atmosphere.

What is convection current?

Convection current  is the heat transfer by fluid movement in the earth crust between different temperature regions. The density of fluids differs due to the temperature gradients and thus heated fluids raises and cooled fluid sinks.

The heated fluid movement causes the movement of plates of earth. The molten rock deep inside the earth crust circulates by the convection current.

Hence, the main cause of global convection current is the differential heating of the atmosphere.

Which of these is a property of a substance that is composed of atoms that are held together by metallic bonds?
It has a low melting point.
It can be flattened and bent.
It cannot be shaped into wires.
It does not conduct electricity.

Answers

Answer:

B: it can be flattened and bent

Explanation:

Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.

Metals are bonded together by metallic bonds.

Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.

The property of a substance that is composed of atoms that are held together by metallic bonds is  it can be flattened and bent

What is metallic bond ?

Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.

The metallic bond is a force of attraction which is responsible for holding the atoms together,  releases electrons to achieve the configuration of a noble gas.

in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud

The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them  called as  "sea of ​​electrons"  by cohesive bond.

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.

Answers

Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{a*b}{c}[/tex]

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]

bushels of corn=  285

The six-row combin harvests 285 bushels of corn per hour.
