Answer: D. It produces hydrogen ions in a solution.

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydrogen ions (H^+) in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Hence, the correct statement is arrhenius acid produces hydrogen ions in solution.

Hello.

The answer is: D it produces hyrogen ions in a solution.

This is correct because when Arrhenius acid it turns into hydrogen ions.substance as an acid if it produces hydrogen ions H(+) or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH(-) in water.

NaOH is a strong base. What two ions do you expect to find in a solution of NaOH?
Marrrta [24]

According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.

Here NaOH is a base as it can donate OH-.

As NaOH is a strong base it will have very high dissociation constant.

Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.

NaOH  --> Na^{+}(aq)  + OH^{-}(aq)

Thus in a solution of NaOH we will expect  the following two ions

Na^{+}  + OH^{-}[/tex]

You are using a beaker to measure volume. the beakers graduation begin at 20ml and in indicate every 10ml up to 80 ml. the botto
dolphi86 [110]

Answer:

b) 47ml

Explanation:

The beaker would look like this:

60 mL

50 mL

-------  The bottom of the meniscus is here

40 mL

30 mL

So <u>we have between 40 and 50 mL</u>. There are 10 mL of "distance" between those two values, and three fourths of that difference is (10 * 3/4) 7.5 mL.

So <em>the volume is 47.5 mL</em>, but because the measurement instrument (the beaker) does not handle decimals, the value we should report is 47 mL.

A(n) _____ bond joins these two oxygen atoms. Two oxygen atoms with two electron shells. The atoms share four electrons located
Lisa [10]

Answer:

double covalent bond  

Explanation:

Double covalent bond -

It is the type of interaction observed between two species , which share the electrons in order to attain stability , is referred to as covalent bond.

The shared electrons are referred to as the bonding pairs or the shared pairs .

Stability and completion of the octet is the driving force for the formation covalent bond.

The molecules of the organic compound usually shows this type bonding .

A double covalent bond is the one which have four shared pair of electrons , i.e. two covalent bonds.

Hence , from the question,

Oxygen is capable to show double covalent bond .
