Bases have a pH of above 7, and are bitter and slippery.
Answer: c. hydroxide ions
Final answer:
Bases in a solution produce hydroxide ions (OH-). This ability to donate a hydroxide ion is what characteristically defines a substance as a base.
Explanation:
When bases dissolve in water, they produce hydroxide ions (OH-). In chemistry, bases are substances that can accept hydrogen ions (H+) or donate a hydroxide ion. For example, when sodium hydroxide (NaOH), a common base, dissolves in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). This is the characteristic that defines a substance as a base.

The space occupy by the 180.0 g of gold will be 9.32 cm³
Explanation:
Given data:
Mass of gold = 180.0 g
Volume occupy by the gold = ?
Solution:
The given problem will be solved through the density formula.
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
The density of gold from literature is 19.320 g/cm³
Now we will put the values in formula.
19.320 g/cm³ = 180.0 g/ V
V = 180.0 g/ 19.320 g/cm³
V = 9.32 cm³
The space occupy by the 180.0 g of gold will be 9.32 cm³.

What is helium particles?
Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution to the Schrodinger equation for the helium atom has not been found.
A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution.
Helium is the element which you can find on the upper right side of the periodic table with atomic number 2. It comes first amongst the family of the noble gases. Helium falls under inert gas since its outermost electron orbital is full with two electrons.
The answer is 69.253.
