Answer:

<u></u>

  • <u>0.289M</u>

Explanation:

<u>1. Balanced chemical equation</u>

  • Ba(OH)₂(aq)   +   2HNO₃(aq)   →   Ba(NO₃)₂(aq)   +   2H₂O(l)

<u />

<u>2. Determine the number of moles of HNO₃ in the solution</u>

  • M = n/V(in liters)
  • n = M × V = 0.425M × 0.050 liter = 0.02125‬ mol HNO₃

<u>3. Use the mole ratio from the balanced chemical equation and the number of moles of HNO₃ to determine the number of moles of  Ba(OH)₂.</u>

       \dfrac{1molBa(OH)_2}{2molHNO_3}\times 0.02125molHNO_3=0.010625molBa(OH)_2

<u>4. Determine the molar concentration of the solution of Ba(OH)₂</u>

  • M = n/V(in liters)
  • M = 0.010625mol/0.0368liter
  • M = 0.289M ← answer

A researcher selects three regions X, Y, and Z, and records the types of discharge that enter the regions’ rivers.
elixir [45]

Region Z should be monitored more closely to avoid health issues.

<h3>Why region Z should be monitored?</h3>

Region Z should be monitored more closely to avoid potential health issues because region Z produces waste from chemical plants which are dangerous for our water and environment so we can conclude that Region Z should be monitored more closely in order to avoid health issues.

A species that is formed when a base gains conjugate base. b. conjugate acid. a proton is a c. strong base d. strong acid.
SSSSS [86.1K]

Answer:

The correct option is: conjugate acid

Explanation:

Bases are the chemical substances that are proton acceptors and electron-pair donors. Therefore, when a base accepts a hydrogen proton from an acid it forms a conjugate acid.

Therefore, conjugate acids are formed when a base accepts a hydrogen proton from an acid. Also, if the base is a weak base then its conjugate acid is strong. Whereas, if the base is a strong base then the conjugate acid is weak.

xeze [42]

Answer:

Explanation:

Question 1:

atomic number/number of protons

All atoms of the same element share the same number of protons or atomic numbers. In grouping elements on the periodic table, the periodic law is often used. The modern periodic law states that "properties of elements are a periodic function of their atomic number". The atomic number of an element distinguish it from others.

Question 2:

The two carbon atoms would be quite different as they are isotopes. Isotopy is the existence of two or more atoms of the same element having  the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

Naturally, carbon exists in two isotopic forms:

                        ¹³₆C and ¹⁴₆C

One might see these different samples in a rock and in the skin cells. They are simply isotopes. Isotopes have the same electronic configuration and hence similar chemical properties. Only their masses differ.
