if you do 40 J of work on an object move it to meters, you apply ____ newtons of force to the object

Answer:

~0.14

Explanation:

There are roughly ~0.14 moles in 4.5g of Sulfur. 1 mol = 32.06 g of Sulfur, so we just find the ratio and then multiply.

Answer:

[tex]\boxed {\boxed {\sf About \ 0.14 \ mol \ S }}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass. This can be found on the Periodic Table.

We can use this number as a ratio or fraction.

[tex]\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Multiply by the given number of grams: 4.5

[tex]4.5 \ g \ S *\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Flip the fraction so the grams of sulfur cancel.

[tex]4.5 \ g \ S *\frac{1 \ mol \ S }{32.07 \ g \ S}[/tex]

[tex]4.5 *\frac{1 \ mol \ S }{32.07 }[/tex]

[tex]\frac{4.5 \ mol \ S }{32.07 }[/tex]

[tex]0.140318054 \ mol \ S[/tex]

The original measurement of grams had 2 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place.

The 0 in the thousandth place tells us to leave the 4.

[tex]0.14 \ mol \ S[/tex]

There is about 0.14 moles of sulfur in 4.5 grams.

Answer:

B   proofread the message.

Explanation: Hope this helped

Answer:

Ortho nitrophenol is more acidic than ortho-methoxyphenol.

Reason:

This is because the nitro-group is an electron-withdrawing group. In the case of ortho methoxyphenol; methoxy group is an electron-releasing group. Thus, it increases the electron density in the O−H bond and hence, the proton cannot be given out easily.

Answer:

your carbon footprint is how often you use a car of vehical you can decreese it by riding a bike or walking.

Explanation:

Carbon footprint is like when you ride a car and it produces lots of carbon monoxide in the air. Ways to reduce it is by walking, riding a bicycle or using the bus for transportation. Hope this helps.

Answer:

Be^2+

Explanation:

The atomic number indicates the number of protons so the element is Be (beryllium)

So now we know that a neutral atom contains four electrons but there are 2 so that means two electrons were taken away, making it positive. It would be a 2+ charge.  

Answer:

hydrogen nitride

Explanation:

since they are bounding they would become a compound, and so it would need to expand

Answer:

there are 5 molecules in SO⁴

Answer:

Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.

Answer:

Water, solar energy, carbon dioxide

Explanation:

Explanation:

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

oxyacid, oxoacid

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

Many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. We use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil.

Answer:

(C5H7)8

Explanation:

It's empirical formula is given as; C5H7

Molar mass of carbon(C) = 12 g/mol

Molar mass of hydrogen(H) = 1 g/mol

We are told that it's molar mass is 536 g/mol.

To find the molecular formula;

Molecular formula = n × empirical formula

Thus;

n = 536/((12 × 5) + (1 × 7))

n = 8

Thus;

Molecular formula = (C5H7)8

Answer:

23.4

Explanation:

23.4 g mass of sulfur yielded by this reaction.

[tex]Percentage yield = (Actual / Theoretical)\times 100[/tex]

The theoretical yield for S is as follows:-

[tex]71.0\ gCl_2\times\frac{1\ molCl_2}{71\ g Cl} \times\frac{1}{1} \ mol\times\frac{32.1\ g}{molS} =32.1\ gS[/tex]

Actual yield=[tex]32.1\ gS\times73\%=23.4\ g\ S[/tex]

Explanation:

Answer: Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria.

Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.

Green substance in producers that traps light energy from the sun, which is then used to combine carbon dioxide and water into sugars in the process of photosynthesis Chlorophyll is vital for photosynthesis, which helps plants get energy from light.

Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

Answer:

82.9% Is the percent yield

Explanation:

First, we need to balance the equation.

Ca(CO3) + 2HCl → H2O + CO2 + CaCl2

Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.

[tex]\frac{200g HCl}{1}[/tex] x [tex]\frac{1 mole HCl}{36.46gHCl}[/tex] x [tex]\frac{1 mol CO2}{2molHCl}[/tex] x [tex]\frac{44.01CO2}{1molCO2}[/tex] =120.707 g (theoretical yield)

Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.

Answer:

the answer is 172g

Explanation:

200 × 0.86 = 172g

Answer:

5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

Explanation:

The balanced equation in this question is

Iron + Sulfur = Iron(II) Sulfide

Fe (II) + S --> Fe(II)S

Thus one mole of sulfur reacts with one mole of Fe(II)

Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
