Answer:
There are 19 atom sin total in antimony silicate, 
.
Explanation:
Number of antimony atoms = 4 × 1 = 4
Number of silicon atoms = 3 × 1 = 3
Number of oxygen atoms = 3 × 4 = 12
Number of atoms in antimony silicate:
= 4 + 3 + 12 = 19
There are 19 atom sin total in antimony silicate, .
The answer is <span>B. element.
An element is composed of only one kind of atom and cannot be separated into simpler substances. Oxygen (O) is the element.
A compound is a substance composed </span><span>of two or more <em>different </em>atoms chemically bonded to one another, for example, water (H</span>₂<span>O) consists of 2 atoms of hydrogen (H) and 1 atom of oxygen (O), so it is the compound.
A mixture consists of two or more substances that are not chemically combined. Solutions and colloids are mixtures.</span>

Answer:
The formula for calculating pH is pH=−log[H_3O+ ]
pH is the negative logarithm (to base 10) of hydronium ion concentration
The pH Formula can also be expressed as
PH= - log[H+ ]
