Hey there!

This atom has 10 protons.

If this atom has an atomic mass of 22, that means the sum of protons and neutrons is 22.

p + n = 22

p = 10

Which makes this true:

10 + n = 22

Subtract 10 from each side to solve for n, the number of neutrons.

n = 12

An atom that has the atomic number of 10 and an atomic mass of 22 has 12 neutrons.

Hope this helps!

H3C6H507(aq) + 3NaHCO3(aq) - Na3C6H5O7(aq) + 3C02(g) + 3__
zavuch27 [327]

Answer: 3<u> H₂O</u>

<u />

Explanation:

This is an example of a common chemical reaction

ACID + CARBONATE --> SALT + WATER + CARBON DIOXIDE which implires

CITRIC ACID  + SODIUM BICARBONATE ----> SODIUM CITRATE + WATER + CARBON DIOXIDE .  

The full chemical equation is  given by

H3C6H5O7(aq)  + 3NaHCO3(aq) --> Na3C6H5O7(aq) + 3CO2(g) + 3<u>H2O</u>(l)

The reaction produces a  fizz due to the  release of  carbon dioxide which can be also seem when an Alka-Seltzer® tablet is dissolved in water.

Pls HELP!!!! Why does copper oxide appear on a penny faster when a penny is heated in a flame than when the penny is at room tem
balu736 [363]

The rate of reaction between oxygen and copper is higher at high temperature. The rate of reaction between oxygen and copper is lower at room temperature.

at high temperature copper penny will react with oxygen as shown below

2Cu(s)+O_{2}-->2CuO

The reaction does not occur easily at room temperature

We can say that the reaction between copper and oxygen is an endothermic reaction so the rate of reaction is high at high temperature.

The bond energy of oxygen molecules need energy to react with copper and form copper oxide.

Covalent compounds are generally not very hard. Justify the statement.
Eduardwww [97]

Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.

<h3>COVALENT COMPOUNDS:</h3>

Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.

Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

Examples of covalent compounds are:

  1. H2 - hydrogen
  2. H2O - water
  3. HCl - hydrogen chloride
  4. CH4 - methane

How does a negative ion differ from an uncharged atom of the same element?
Katena32 [7]
When an atom or molecule accepts or looses an electron or electrons it gets either negative charge (when electrons gained) or a positive charge (when looses electron). The negative ion is called Anion and positve ion is called the Cation. An Ion can be Atomic or Polyatomic.

Example:
              Sodium when looses one electron forms a cation i.e. Na⁺

              Chlorine when gains one electron forms an Anion i.e. Cl⁻

Result:
          <span>A negative ion (Anion) differ from an uncharged atom of the same element in the number of electrons. An anion contains more electrons than its corresponding Neutral Element.</span>
