How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?

Answers

Answer 1

Answer:

[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)

Explanation:

The molecular weight of acetylene is  26.04 g/mol

Molecular weight of carbon is equal to 12.011 g/mol

Two carbon atom produces one acetylene molecule.

Thus, 2 * 12.011 g/mol of carbon is used to produce  26.04 g/mol of acetylene,

Amount of carbon required to produce 59.8 grams of acetylene

[tex]\frac{2*12.011}{26.04} * 59.8 \\= 55.1657[/tex]grams/mol

[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)

What is electromagnetic spectrum?

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer:

D

Explanation:

Option D is the correct Lewis structure of ozone.

Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.

In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.

How many molecules are in 7.9 mol of H202

Answers

Answer: There are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]H_2O_2[/tex] molecule contains = [tex]6.023\times 10^{23}[/tex]  molecules

Thus 7.9 mole of [tex]H_2O_2[/tex] molecule contains = [tex]\frac{6.023\times 10^{23}}{1}\times 7.9=47.6\times 10^{23}[/tex] molecules

Thus there are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

Which phrase describes runoff?

2.river water that empties into an ocean

3.water from streams that flows into larger rivers

4.water from rain and snow that travels to streams
Please help!

Answers

Explanation:

water from rain and snow that travels to streams

Please help!

Water from a rain and snow that travels to streams are examples of run off. These natural processes are part of water cycle and balance the water content in the atmosphere and hydrosphere.

What is water cycle ?

Water cycle is a geological phenomenon to balance the  water content in the atmosphere, hydrosphere and in the biosphere. The water bodies evaporate by the heat radiated by sun.

The air moisture can be restored to the land through the cooling of the vapor and pour as rain. This best illustrates the interaction between atmosphere and hydrosphere.

Rain, snow, sleet, or hail that reaches a surface stream without ever going below the soil's surface is referred to as surface runoff. It differs from direct runoff, which is runoff that directly reaches surface streams following rainfall or snowmelt. Hence option 4 is correct.

An electron is transferred from sodium to chlorine and a covalent bond is
formed.
An electron is shared between sodium and chlorine and a covalent bond is

Answers

Answer:

First Statement is correct

Explanation:

An electron is transferred from sodium to chlorine and ionic bond is formed.

Hope it help!!

If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.

What is ionic bond ?

The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.

When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.

The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.

Thus, option A is correct.

[please answer fast!] If the hydroxide ion concentration is 2x10^-3 M, what is the pH of the solution? Show your working.

Answers

Answer:

pH = 11.30

Explanation:

pH is defined as -log [H⁺]

To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

[H⁺] = 1x10⁻¹⁴ / [OH⁻]

[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M

[H⁺] = 5x10⁻¹²M

pH = -log (5x10⁻¹²M)

pH = 11.30

Oxygen has 8 positively charged protons what is the number of negatively charged electrons in an atom of oxygen?

Answers

Answer:

8 electrons (e-)

Explanation:

In the atom of every elements, there are three sub-atomic particles namely: protons, electrons, and neutrons. The protons are the positively charged particles, the electrons are negatively charged while the neutrons are neutrally charged.

In an uncharged or neutral atom i.e. charge 0, the number of protons is always equal to the number of electrons because they cancel each other out. When a difference occurs in the number of these particles, the atom becomes charged i.e. an ion. According to this question, oxygen atom (O) contains 8 positively charged protons, this means that it also contains 8 negatively charged electrons in its atom.
