Chemistry

Bess [88]3 years ago

Answer:

This would depend on the intensity or the size of a fire.

Explanation:

For instance, a small fire could be described as: kindled, flickering, dancing (in the case of a candle flame), smoldering, or crackling.

A medium size fire, such as a camp fire or a fireplace could be described as: crackling, blazing, burning, or roaring.

While a large or very intense fire (such as a forest fire or a house fire) could be described as: roaring, blazing, burning out of control, consuming, raging, or destroying.

If you were more looking for synonyms of ‘fire’, here are a few of my favorites: flame, blaze, incinerate, immolation, and inferno. (Edited to add a few I remembered: pyre, conflagration, and scorching.)

Answer:

Fire is something that's red and sorta orange is hot and can burn you but fire can be good and bad at some points for example fire can be used as a campfire,fireplace at home,and lighting candles. Fire is also very dangerous tho ,you can burn yourself if your not careful it can light your house on fire and that wouldn't be very safe. In simple words i would say fire is something that can have advantages and disadvantages.

Ahhh hope thats alright im on online classes but i wanted to help!!

What is the best description for a solution with a hydroxide-ion concentration equal to 1 x 10-4 m?
djverab [1.8K]

Answer:

This is a basic solution

Explanation:

To be able to provide a succint description of this solution, from the given parameters we can deduce the pH of the solution.

Given parameters:

Concentration of OH⁻ = 1 x 10⁻⁴M

Solution

          We knonw that pOH = -log₁₀[OH⁻]

                   pOH = -log₁₀ 0.0001 = - (-4) = 4

For an aqeous solution:

                  pH + pOH = 14

                  pH = 14 - 4 = 10

The pH of the solution has been derieved to be 10

This is a basic solution

If the formation of NaCl proceeds according to the following equation and change in enthalpy, what is the reaction and change in
Sergio039 [100]

Answer:

  • <em>2NaCl → 2Na + Cl₂, ΔH = 822 kJ </em>

Explanation:

The chemical <em>equation</em> for the <em>formation of NaCl</em> is:

  • Na + (1/2) Cl₂ → NaCl , ΔH = - 411 kJ

That equation means that 1 mole of NaCl is formed by the reaction of 1 mole of Na and 1/2 mole of Cl₂, with a release of energy of 411 kJ.

The <em>decomposition</em> of <em>NaCl</em> is the inverse of the <em>formation</em> reaction; thus, you swift products and reactants and inverse the sign of the <em>change in enthalpy:</em>

  • NaCl → Na + 1/2 Cl₂, ΔH = 411 kJ

Since you want the decomposition of 2 moles you multiply the equation and the ΔH by 2:

  • 2NaCl → 2Na + Cl₂, ΔH = 822 kJ ← answer

How many moles of tin,Sn, are in 2500 atoms of tin?
Assoli18 [71]

Answer:

4.15×10⁻²¹ moles of Sn

Explanation:

This question can be solved by a simple rule of three.

We know that 1 mol contains 6.02×10²³ particles.

In this case, our particles are the atoms, so:

6.02×10²³ atoms / 1 mol . 2500 atoms = 4.15×10⁻²¹ moles.

The knowledge of mol can be applied for everything:

A mol of molecules

A mol of atoms

A mol of a compound
