How many moles of hydrogen gas will form if 0.35 moles of Na reacts with an excess of water?​

Answer:

option a. second

.............

Answer:

j one or more parents. that's the answer

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:

(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

Explanation:

Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. ... The screw consists of a narrow inclined plane wrapped around a cylinder.

Answer:

hydrogen nitride

Explanation:

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

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:

Nitrogen and chlorine have similar electronegativities, making individual N-Cl bond essentially non-polar. therefore its true

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:

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

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.

The AK steel plant is in Coshocton County,Ohio. The fossil fuel used to melt and refine Iron into steel is COAL.

Answer:

A nonrenewable resource is a substance that is being used up more quickly than it can replace itself. Its supply is finite. Most fossil fuels, minerals, and metal ores are nonrenewable resources. Renewable resources such as solar and wind power and water are unlimited in supply.

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.

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: 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:

ion-dipole interaction

Explanation:

Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.

The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.

When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.
