Yes, gravity has a pull on you either way, which can be measured despite how far up or down low you are.

No, when ascending, you would weigh more, and when you descend, you weigh less.

This is due to the difference in the effect of gravity.

A simple way to estimate whether a molecule is a strong electrolyte, a weak electrolyte, or a nonelectrolyte is to examine an eq
borishaifa [10]

Answer:

Explanation:

We classify the behaviours of electrolytes based on their electrolytic conduction. This is what makes them breaks down when in aqueous solutions with water.

A strong electrolyte is one that ionize completely when in aqueous solutions. Their ionization can be shown below using appropriate chemical notation:

   An example of a strong electrolyte is NaCl:

                NaCl _{aq} → Na⁺_{aq} + Cl⁻_{aq}

Such reactions have a single forward arrow. Since they ionize complete, they have a large amoung of ions present in their aqueous form and would readily conduct.

A weak electrolyte is made up of compounds that ionize partially or slightly in their aqueous solution. The amount of ions produced per mole of compounds is relatively small compared to those of strong electrolytes. Examples ae organic acids, weak bases, and water. This ionization is shown below for methanoic acid:

    HCOOH_{aq} ⇄ HCOO⁻_{aq} + H⁺_{aq}

This sort of reaction is an equilibrium reaction. This is why we have the double arrow.

None electrolytes do not ionize at all in aqueous solutions and they produce no ions.

What are the products of the acid-base reaction between HNO3 and NaOH? A. H2O and NaNO3 B. NaH and NO3OH C. HNOH and NaO3 D. NaO
Otrada [13]

Answer:- A. H_2O and NaNO_3

Explanations:- In general, acid+base\rightarrow salt+water

In acid-base reaction the acid gives hydrogen ion and the base gives hydroxide ion and these ions combine to form water. Rest of the ions from acid and base combine to form the salt.

Nitric acid breaks to give hydrogen ion and nitrate ion. Similarly, NaOH breaks to give sodium ion and hydroxide ion. Since, hydrogen ion and hydroxide ions form water, the sodium ion and nitrate ion forms the salt, sodium nitrate.

The reaction is shown as:

HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)

So, the right choice is A.

In micelles: Question options: A) non-polar ends form hydrophilic interactions with water. B) polar ends form hydrophobic intera
AnnyKZ [126]

Answer:

E

Explanation:

A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap
