For me, it is balanced

Explanation:

Because the amount of element Zn reaction is equal the production. Also as the amount of Hydrogen and Chloride in the reaction and the production are equal.

C) The boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday.

Explanation:

The sentence that has been in the parallel structure has been the boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday has been in parallel structure. Thus, option C is correct.

The parallel structure can be defined as the continuous repetition of the grammatical form in the sentence. The parallel structure has been able to provide equal importance to the tasks in the sentence.

In the given sentence, the varying task has been late shifts, open tomorrow, and work on holidays. The grammatical form of who can has been able to give equal importance to every task with the repetition.

Thus, boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday has been in parallel structure. Thus, option C is correct.

Explanation:

Answer:

Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

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.

Answer:

iron+flourine.............iron flouride

Fe+F2.............FeF3

the above reaction is not balanced

now to balance this reaction

2Fe+3F2...........2FeF3

now this reaction is balanced

The balanced equation is: 2Fe + 3F2 ⇒ 2FeF3

A chemical equation needs to be balanced if you want to make the wide variety of the atoms of the reactants equal to the variety of the atoms of the goods.

Given,

Iron + fluorine ⇒ Iron Flouride

Fe + F2 ⇒ FeF3

Now to balance this reaction:

2Fe + 3F2  ⇒ 2FeF3

This reaction is balanced.

This medicine is a mixture manufactured from nutrients, iron, and fluoride. it's miles utilized in infants and youngsters to deal with or prevent deficiency because of terrible weight loss programs or low tiers of fluoride in drinking water and other sources.

#SPJ2

Answer:

Explanation:

zn is oxidized because its oxidation number is increased from zero in zn to +2 in zn(No3)2

Ag is reduced because its oxidation number is reduced from +1 in AgNo3 to zero in Ag

oxidation number of zn(s) is zero while the oxidation number of zn in zn(No3)2  is

zn(No3)2=x+(5*2)+(-2*6)=x+10-12=x-2

x-2+2=2

x=2

the oxidation of Ag in AgNo3

AgNo3=x+5+(3*-2)=x+5-6=x-1

x-1+1=1

x=1 while the oxidation number of Ag is zero

so zinc is oxidized and silver (Ag) is reduced

Explanation:

55 kilometers per hour to meters per second

First we have to convert the kilometers to grams;

1 kilometer = 1,000 meters

This means we have;

55000 meters per hour

Converting hour to seconds;

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 * 60 = 3600 seconds

We divide 55000 by 3600;

55000 / 3600 = 15.28 meters per second

Answer:

Hydrogen

Explanation:

Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.

According to the electronic configuration, element with lowest atomic mass is hydrogen.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Explanation:

Na2CO3(ag) +2k(s) →K2CO3 (aq) + 2Na(s)

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

Explanation:

The volume of the block of wood of 360 grams has been 60 ml or 60 [tex]\rm cm^3[/tex].

The density of an object can be defined as the mass of an object per unit volume. Density plays a pivotal role in the object sinks or floats into a liquid.

If the density of an object is lighter than the density of the liquid, the object will float onto the liquid. If the density of an object is more than the density of the liquid, the object will sink in the liquid.

Density  can be given by:

Density = [tex]\rm \dfrac{mass}{volume}[/tex]

Mass of the object = 360 grams

Density = 60 g/[tex]\rm cm^3[/tex]

Volume = [tex]\rm \dfrac{mass}{density}[/tex]

Volume = [tex]\rm \dfrac{360}{60}[/tex]

Volume = 60 [tex]\rm cm^3[/tex] .

1 [tex]\rm cm^3[/tex] = 1 ml

Volume = 60 ml.

The volume of the block of wood of 360 grams has been 60 ml or 60 [tex]\rm cm^3[/tex].

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.
