Answer:

I assume your talking about carbon when you say 12 so it'd be 12 grams if you are

Explanation:

The molar mass of any substance in grams per mole is numerically equal to the mass of that substance expressed in atomic mass units.

Hope this helps you some

Now imagine you have several of such dipoles, and place them regularly between the plates. For this part of the pre-lab, you can

Dmitry_Shevchenko [17]

Answer:

Dipole is two equal but opposite charges in one. As like charges repels and unlike charges attracts each other. If dipole are in electric field region, it positive side will be attracted to the negative field and vis-versa. This will result to different movement or stationary based on the orientation of the field. If the interaction between other dipole is considered this effect may be obstructed

5) Chlorine has 7 valence electrons. Neon has 8 valence electrons. Which on is more likely to undergo a

kari74 [83]

Answer:

well, chlorine will undergo in a chemical reaction

Explanation:

neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.

whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence

it will take place in a chemical reaction

Use a Punnett square to predict the cross of a homozygous tall parent with a homozygous short parent, if tall is dominant over s

ycow [4]

Answer:

All offspring are tall when a homozygous tall parent with homozygous short parent.

Explanation:

When we crossed homozygous tall parent with homozygous short parent, we conclude that all offspring are tall, because homozygous short parent are supressed under the homozygous tall parent, due to law of dominance.

Law of dominance states that, recessive alleles are suppressed by dominant alleles but they can appear in F2 generation.

Using a punett square, we can predict the cross between homozygous tall and homozygous short parent.

The phenotypes are: All are tall plants (4:0).

When dilute HCL is added to zinc pieces taken in a test tube

Romashka-Z-Leto [24]

Answer:

zince chloride will be formed and hydrogen gas will be librated.

Explanation:

When dilute HCl is added to zinc pieces, a rection will takes place as follows :

$Zn+HCl\rightarrow ZnCl_2+H_2$

It means that zinc chloride will form when zinc reacts with dilute HCL. Also hydrogen gas will produced.

As zinc is more reactive than hydrogen, it displaces hydrogen from its solution and forms zinc chloride. The form product is white in color and H₂ is an odorless gas.

Hence, zince chloride will be formed and hydrogen gas will be librated.

When an object is lifted 6 meters off the ground, it gains a certain amount of potential energy. If the same object is lifted 18

AlexFokin [52]

Answer:

The answer to your question is the letter C. three times as much

Explanation:

Data

First step = 6 m

Second step = 18 m

Potential energy is the energy stored that depends on its position.

Formula

Pe = mgh

m = mass; g = gravity; h = height

Potential energy of the first step

Pe1 = 6mg

Potential energy of the second step

Pe2 = 18mg

-Divide the Pe2 by the Pe1

Pe2/Pe1 = 18mg/6mg

= 3
