B. All atoms of silver have the same atomic number but different numbers of neutrons in the nucleus.
Answer:
If it contains only 2 elements it will begin with “hydro” as in
hydrochloric acid (HCl). If it contains more than 2 elements it is named based on the polyatomic (oxy) anion, as in nitric acid (HNO3), nitrous acid (HNO2), sulfuric acid (H2SO4). If the element has more than one possible charge, the value of the charge comes after the element name and before the word ion. Thus, Fe 2+ is the iron two ion, while Fe 3+ is the iron three ion.
Explanation:
Because of the motion, the faster the particles move , the higher temperature goes
<u>Answer:</u> The volume of solution is 195.8 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 0.575 M
Given mass of nickel (II) acetate = 19.9 g
Molar mass of nickel (II) acetate = 176.8 g/mol
Putting values in above equation, we get:
To prepare 0.575 molar nickel (II) acetate solution, we need to add 19.9 grams of nickel (II) acetate to 195.8 mL of solution.
Hence, the volume of solution is 195.8 mL
Answer:
490 J.
Explanation:
The following data were obtained from the question:
Mass (m) = 5 Kg
Height (h) = 10 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (P.E) =..?
Potential energy is the energy stored in a body by virtue of its location. Mathematically, it can be expressed as:
P.E = mgh
Where:
m is the mass of the object measured in kilograms (Kg).
g is the acceleration due to gravity and the value is 9.8 m/s².
h is the height to which the object is located measured in metre (m)
P.E is the potential energy measured in joule (J).
With the above formula, we can obtain the potential energy possed by the object as follow:
P.E = mgh
P.E = 5 x 9.8 x 10
P.E = 490 J
The,the potential energy possed by the object is 490 J
