a gas has a temperature of 14C, and a volume of 4.5 liters. if the temperature is raised to 29C and the pressure is not changed, what is the new volume of the gas?

The ionic compound are crystalline solids at room temperature

Explanation:

they are quite strong because they contain strong ionic bonds

At the room temperature, ionic compound will be crystalline solids.

Ionic compounds are made up of ions kept together by the attraction of oppositely charged ions. One of the most well-known ionic compound is common salt (NaCl). Molecular compounds are made up of separate molecules that are bonded together through electron sharing.

The elements of a crystalline solid are grouped in a tightly packed microscopic structure, generating a crystal lattice that stretches in all directions.

Explanation:

Answer: it has full valence shells

Explanation: Hope this is it

Answer:

Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).

The answer is True.

Explanation:

The sentence above is true it all adds up.

Ca(OH)₂⇒ Ca²⁺ + 2OH⁻

Ksp = [Ca²⁺][OH⁻]²

Ca(NO₃)₂ ⇒ Ca²⁺ + 2NO₃⁻

Input in Ksp

1.3 x 10⁻⁶ = 0.1 . 4s²

s² = 3.25 x 10⁻⁶

s = 1.8 x 10⁻³

1.8 x 10⁻³ is the molar solubility. Solubility is the amount of a substance that can be dissolved in a liquid to form a solution.

Solubility is the amount of a substance that can be dissolved in a liquid to form a solution; it is typically represented as grammes of solute every litre of liquid. One fluid's (liquid or gas) solubility in another can be entire (e.g., methanol and water are completely miscible) or partial (e.g., oil and water barely mix). Generally speaking, "like dissolves like" (for instance, the aromatic hydrocarbons dissolves in one another but not in water).

A material's solubility in two solvents is measured by the distribution coefficient, which is used in some separation techniques (such as absorption and extraction). In general, as temperature rises, so do the dissolution rates of solids in liquids, while they fall as temperature rises and rise with pressure for gases.

Ca(OH)₂⇒ Ca²⁺ + 2OH⁻

CO2 and H2O react to form H2CO3 and two bonds are broken each in CO and H2O to form H2CO3.

Chemical bonding refers to the forces of attraction which hold atoms of the same or different elements together in order to form stable compounds or molecules .

Chemical bonding may be either ionic or covalent.

The greater the number of bonds in a compound, the more stable the compound.

During chemical reactions, bonds are broken and new binds are formed.

There are two bonds each in CO2 and H2O.

This, in the reaction between CO2 and H2O react to form H2CO3, , the number of bonds broken in H2O is two and in CO2 is two.

Answer:In water's diagram, the slope of the line between the solid and liquid states is negative rather than positive. The reason is that water is an unusual substance in that its solid state is less dense than the liquid state.

Explanation:

The mass of carbon that resulted from the decomposition of 37 L of carbon dioxide is 19.8 g

CO₂ —> C + O₂

From the balanced equation above,

1 L of CO₂ decomposed to produce 1 L of C.

Therefore,

37 L of CO₂ will also decompose to produce 37 L of C

At standard temperature and pressure (STP),

22.4 L = 1 mole of C

Therefore,

37 L = 37 / 22.4

37 L = 1.65 mole of C

Thus, the mass of Carbon can be obtained as follow:

Mass = mole × molar mass

Mass of C = 1.65 × 12

Mass of C = 19.8 g

Thus, 19.8 g of carbon were obtained from the reaction.

Explanation:

1) First convert to pOH as OH is the dissociating species in a base equilibrium.pH + pOH = 14 (at 25 C)pH=13, hence pOH = 1,Hence [OH] = 10^-1 Mdiluting by factor of 10 with pure water gives [OH] = 10^-2 MThe new pOH = 2, hence the new pH is 12In general, dilution (with pure water) by a factor of 10 moves the pH 1 unit in the direction of the pH of water (pH 7). i.e. it moves up for acids, down for bases.(At infinite dilution of either acids or bases, you’d have pure water - obvious when you think of it like that)

When NaOH solution is accidentally spilled on your skin while trying to transfer it into a pH paper, one should rinse the exposed skin with water.

Chemical reagents can be found in the laboratory and are harmful to the human skin.

However, when transferring an alkaline solution of NaOH to the pH paper and one accidentally splashes it onto the skin, water should be poured to the affected part immediately.

The water washes away the chemical before it starts to have negative effect on the skin.

Explanation:

We can use Planck's equation. Recall that:
[tex]\displaystyle E = h\nu[/tex]

Where h is Planck's constant and ν is the frequency.

We also have that:
[tex]\displaystyle \lambda \nu = c[/tex]

Where c is the speed of light and λ is the wavelength. Hence:

[tex]\displaystyle \nu = \frac{c}{\lambda}[/tex]

Therefore:
[tex]\displaystyle E= h\left(\frac{c}{\lambda}\right)[/tex]

Solving for λ yields:
[tex]\displaystyle \lambda = \frac{hc}{E}[/tex]

Hence substitute. Recall that h = 6.626 × 10⁻³⁴ Js and c = 2.998 × 10⁸ m/s:

[tex]\displaystyle \begin{aligned} \lambda & = \frac{(6.626\times 10^{-34}\text{ Js})(2.998\times 10^8\text{ m/s})}{4.56\times 10^{-19} \text{ J}} \left(\frac{1\times 10^9\text{ nm}}{1\text{ m}}\right) \\ \\ & = 436\text{ nm}\end{aligned}[/tex]
