The naming rules for CaCO3 would be A. Metal+ Polyatomic Anion.
The greatest visual evidence you can use when trying to determine if a solution is saturated is to look and see if everything in the test tube is a single color and a single consistency.
Answer:
18.73× 10²³ formula units
Explanation:
Given data:
Number of moles of Ca(NO₃)₂ = 3.11 mol
Number of formula units = ?
Solution:
Avogadro number:
"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance"
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Number of formula units of Ca(NO₃)₂:
1 mole contain 6.022 × 10²³ formula units
3.11 mol × 6.022 × 10²³ formula units / 1 mol
18.73× 10²³ formula units
Answer:
A) An Alkaline
Explanation:
An alkane that is pentane which is substituted by a methyl group at position 3. It is used as a solvent in organic synthesis, as a lubricant and as a raw material for producing carbon black.
The line segment is describe as a line which joints two points. The word segment is denotes the end points of the line. The symbol of the line segment is AB. This symbol is indicating a line from the point A to the point B.
- Generally, the line segment has two endpoints. The meeting point of two line segments is called as the vertex and also it is considered as a common endpoint on the other hand line is a straight path of points that goes on and on in two directions
- Vertex is a point where two rays meet OR where the sides of a polygon meet OR the point where three or more edges of a solid figure meet and the angle is Formed by two rays that have the same endpoint
