Give the following number of protons, neutrons, and electrons in the following isotope:
valina [46]

Answer:

47, 68, 47

Explanation:

Let's consider the following isotope: ¹¹⁵Ag.

If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.

Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.

The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:

p⁺ + n⁰ = 115

n⁰ = 115 - p⁺ = 115 - 47 = 68

The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.

lana [24]

Answer:

heat and pressure

Explanation:

A metamorphic rock is a changed rock. It is formed a result of mineral changes in a pre-existing rock in the presence of temperature and pressure conditions.

Metamorphic transformation in rocks begins to occur when minerals starts to change from their original and usual form. Most metamorphic rocks are formed as a result of burial into deep seated environment or when subjected to conditions that can elevate the temperature and pressure in a rock.

Consider the reaction H2(g) + I2(g) Double headed arrow. HI(g) with an equilibrium constant of 46.3 and a reaction quotient of 5
Alika [10]

Answer:

The reaction shifts to the left.

Explanation:

Equilibrium constant (K) = 46.3

Reaction Quotient (Q) = 525

The relationship between Q and K with their implications are given as;

K = Q (No net reaction)

K > Q (Reaction shifts to the right)

K < Q (Reaction shifts to the left)

Since in this question, Q (525) > K (46.3)

The reaction shifts to the left.
