What is the overall charge on the compound, sodium hydroxide? explain

Chemistry
1 answer:
Fiesta28 [93]2 years ago
7 0

Answer:

Overall, the electric charge of the compound {\rm NaOH} is 0.

Explanation:

Sodium hydroxide {\rm NaOH} is an ionic compound. This compound is made up of a large number of sodium ions {\rm Na^{+}} and hydroxide ions {\rm OH^{-}}.

As the superscripts suggest, each sodium ion {\rm Na^{+}} carries a charge of (+1) while each hydroxide ion {\rm OH^{-}} carries a charge of (-1).

The two types of ions are paired up at a one-to-one ratio within {\rm NaOH}. Charges on these ions would balance one another, such that the overall electric charge on the compound {\rm NaOH}\! would be 0.

Calculate the cost of gasoline for a 320 mile trip from Boston to New
Talja [164]
The cost of gasoline for the trip would cost $57.28 because you first divide 320 by 20 which gives you 16 than after that you do 16 multiplied by 3.58 which gives you $57.28 as your final product

In an atom, the number of neutrons determines most specifically the ________.
lord [1]

In an atom, the number of neutrons determines most specifically the isotopes of an element.

<h2>Further Explanation</h2><h3>An atom  </h3>
  • An atom is defined as the smallest particle of an element that can take part in a chemical reaction.
  • Atoms are made of energy shells and the inner nucleus.
  • It is also made up of subatomic particles, protons and neutrons.
<h3>Neutrons  </h3>
  • They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
  • Neutrons are slightly heavier than protons.
  • The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.
<h3>Protons</h3>
  • Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
  • The number of protons differ from one element to another and thus used as the atomic number of an individual element.
  • The nucleus of an atom is positively charged due to the positive charge of the protons.  
  • Additionally, protons do not take part in chemical reactions but in nuclear reactions.
<h3>Electrons  </h3>
  • They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
  • The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
  • Electrons are the only sub-atomic particles that take part in chemical reactions.
<h3>Isotopes </h3>
  • Isotopes are atoms of the same element that have the same mass number but different atomic number.
<h3>Mass number;</h3>
  • Mass number is the sum of the number of protons and neutrons in the nucleus of an atom of an element.

Keywords: Atom, sub-atomic particles, electrons, protons, neutrons, isotopes

What statement is true about the eight elements on the periodic table termed metalloids?
valina [46]

Answer:

They have properties of both metals and nonmetals

Explanation:

  • Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
  • Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
  • Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
  • Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
  • Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.

A strip of zinc metal was placed in a beaker that contained 120 mL of a solution of copper (II) nitrate, Cu(NO3)2(aq). The mass
jeka94

Answer:

molarity 0.1

Explanation:

mass of copper nitrate =2.4

no of moles exist in 120ml= 2.4/187.5=0.0128mole

molarity =.0.0128/.12=0.1m
