In a neutral atom, the number of protons is equal to the number of electrons.

Given that the charge on the ion of the element is -1. This means that there is one electron more than the number of protons in the element.

The atomic number = Number of protons = 57 -1 = 56

Element with atomic number 56 is Barium.

Mass number of the element = Number of protons + Number of neutrons

                                                = 56 + 80 = 136

So the identity of the species: ^{136}Ba^{-}

SSSSS [86.1K]

Answer:

False

Explanation:

In an exothermic process, the reaction gives off heat, and not takes it in.  If it takes it in from the surroundings, then it would be endothermic.

Substances that make up a mixture __________ their own properties once they are combined to form a mixture. Please help. I need
Stels [109]
I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once  they are combined to form a mixture. 
    I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
  Hope i helped, have a nice day.

The balanced equation for the reaction between iron sulfied and water is best represented by?​
nika2105 [10]

FeS  +   H₂O    →    FeO   +    H₂S

Explanation:

  Iron Sulfide = FeS

  Water = H₂O

                FeS  +   H₂O    →    FeO   +    H₂S

To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations

                 aFeS  +   bH₂O    →    cFeO   +    dH₂S

 a,b,c and d are the coefficients needed to balance up the equation:

      Conserving Fe: a = c

                           S:  a = d

                           H:  2b = 2d

                           O:  b = c

let a = 1, c= 1, b = 1 d = 1

     The balanced equation is:  FeS  +   H₂O    →    FeO   +    H₂S
