Answer:

When the acid is mixed with the water, an immediate chemical reaction takes place. The formation of carbon dioxide causes breakdown of the sample into finer particles.  

The heat in the Stomach rises up, causing esophageal reflux, chronic sinusitis, headaches, eye disorders and problems with the teeth. Furthermore, ingesting cold water creates moisture or “dampness.” Bacteria, candida, and parasites thrive in damp areas, especially in your stomach and uterus.

Answer:

Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. ... Ground-based telescopes can't do the same, because the Earth's atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.

Answer:

Yes Both A) KCL and D) HCL are correct...

Answer:

It's only A

Explanation:

Potassium (K) is a metal and Chlorine (Cl) is a nonmetal, and ionic compounds are formed between metals and nonmetals. So KCl forms ionic bonds.

Hydrogen (H) and Chlorine (Cl) are both nonmetals, and only covalent bonds form between nonmetals. (Only exception is when its an acid, then it's ionic)

Also, the question indicated which "pair" and not "pairs" meaning that there is only one answer, and I'm more likely to go with A rather than D.

Answer:

6.42 °C

Explanation:

Q = mcΔT

Q = energy gain/release (J)

m = mass (kg)

c = specific heat capacity (J/°C/kg)

ΔT = change in temperature (°C)

Qs = n(ΔH°c)

Qs = energy gained/released from substance (kJ)

n = moles (mol)

ΔH°c = molar heat of combustion (kJ/mol)

m = 8.60

n = 0.285

ΔH°c = -810.4

c (of water) = 4184

Qs = 0.285(-810.4)

Qs = -230.964 (or -230964 J)

Q = 230964

230964 = (8.60)(4184)ΔT

230964 = 35982.4(ΔT)

ΔT = 6.4188... °C → 6.42 °C

Answer:

Biocompatibility

Explanation:

I’m a genius and it’s the answer :D

Biocompatibility is a challenge of prosthetic engineering that has been met through tissue engineering. Hence, option B is correct.

Biocompatible materials are used in medical devices, such as menstrual cups, stents, or ventilators.

A biocompatibility problem might happen when some of the materials are trapped in the patient's gingival sulcus.

Tissue engineering is an important field of regenerative medicine for tissue repair (after damaged caused by a disease or an accident, for example).

To offer this possibility, stem cells are important tools owing to their capacity to differentiate into a large number of cells according to the stimuli provided.

Hence, option B is correct.

The empirical formula is the same as the molecular formula because the ratio of atoms in the compound correspond to the number of atoms of each element in the compound.

The empirical formula of a compound shows the ratio of atoms of each element in the compound while the molecular formula shows the number of atoms of each element in the compound.

For the compound, K2CO3, the empirical formula is the same as the molecular formula because the ratio of atoms in the compound correspond to the number of atoms of each element in the compound. It has nothing to do with common factors.

B) It allows chemists to deal with a large number of atoms.

Explanation:

On Edge 2022

The  statement  which best explains the purpose of using a mole in the measurement of matter is that it allows chemists to deal with a large number of atoms.

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

pH + pOH = 14

If pH=8.25, then:

pOH = 14 - 8.25 = 5.75

pOH = -log[OH-]

5.75 = -log[OH-]

-5.75 = log[OH-]

10^(-5.75) = [OH-]

[OH-] = 0,0000017783

[OH-] = 1,78×10^(-6) mol/dm³

Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.

mol = 3.19 × 10^23/6.02^23

= 0.529 mol

mass = 0.529 × 52

= 27.508 g

g to decigram

= 27.508 × 10

= 275.08 decigram

The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.

In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.

If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.
