What is the hydrogen ion and hydroxide ion concentration for a pOH of 3.557? Is the solution an acid or a base?​
UkoKoshka [18]

Answer:

Hydrogen ion concentration is 2.773E-4Mole per DM3

Hydroxide ion concentration is 4.093E-11

It is an acid

Explanation:

PH(H3O)=-LogH3O

PH=3.557

H3O=antilog of -3.557

antilog of -3.557=antilog (0.443 -4)

antilog0.443 ×antilog -4=2.773E-4mole per DM3.

(H3O)(OH)=10^-14

H30=2.773×10^-14

OH= 1.00E-14/2.773E-4

=4.093E-11

it is an acid since the concentration of hydrogen ion is more than the hydroxide ion

Write the nuclear equation for the beta decay Ni-60
viktelen [127]

^6^0_2_7CO\;\rightarrow\;^6^0_2_8Ni\;+\;^0_-1e  is the nuclear equation for the beta decay Ni-60.

<h3>What is beta decay?</h3>

Beta-decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

The nuclear equation for the beta decay Ni-60

^6^0_2_7CO\;\rightarrow\;^6^0_2_8Ni\;+\;^0_-1e

In beta minus (β−) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decay is also known as positron emission.

Hence, ^6^0_2_7CO\;\rightarrow\;^6^0_2_8Ni\;+\;^0_-1e  is the nuclear equation for the beta decay Ni-60.

When naming acids such as HCl, HBr, and HI, the prefix "hydro-" is added and the "ine" of the element is replaced with which of
liberstina [14]

Answer:

a. "-ic"

Explanation:

The correct answer is a. "-ic".

For example:

  • For HCl, the name is Hydrochloric acid. As you can see, the suffix "-ine" of the element (originally chlor<em>ine</em>) is changed to "-ic".

Following the same logic, the name for HBr is Hydrobromic acid; and the name for HI is Hydroiodic acid.
