Answer:

Units Accuracy = the degree to which a measurement can be

Column Matter = anything that has mass and occupies

Space Precision = an indication of how close a measurement is to the correct

Replicated Meniscus = the curved top surface of a liquid

Result Density = the mass of an object per unit volume

Volume = space occupied, measured in cubic

Explanation:

In the fields of science , the Unit Accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's true value.

Column Matter can be defined as anything that had mass and occupies space.

Space Precision refers to the closeness of the measurements to each other. It's the quality, condition, or fact of being exact and accurate.

Replicated Meniscus is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. It can be either concave or convex, depending on the liquid and the surface.

Result Density can be defined as the mass of an object per unit volume.

Volume: The space occupied by any object is called the volume. The volume of an object is the amount of space occupied by the object. Volume is measured in "cubic units".

Nonmetallic elements form ions by _____ valence electrons to complete their outer shell.
Brums [2.3K]

<u>Answer:</u> Non-metals form ions when they gain electrons.

<u>Explanation:</u>

An ion is formed when an atom looses or gains electron.

  • When an atom looses electrons, it will form a positive ion known as cation.
  • When an atom gains electrons, it will form a negative ion known as anion.

Metals are the elements which have a tendency to loose electrons and thus they form cations. <u>Example:</u> Sodium will loose 1 electron to form Na^+ ion.

Non-metals are the elements which have a tendency to gain electrons and thus they form anions. <u>Example:</u> Fluorine will gain 1 electron to form F^- ion.

Hence, non-metals form ions when they gain electrons.

Balance the following equation: H20 --&gt; H2 + O2​
MakcuM [25]

2H2O = 2H2 + O2.

<h3><u>Explanation</u>:</h3>

Balancing equations is very essential because of the fact that it represents the stoichiometric quantities of the reactants needed to react to form the product. The ratio of the weights of reactant and product are also very well understood from this.

Here in this equation, the water is broken into hydrogen and oxygen. The balanced reaction is

2H2O = 2H2 + O2.

Two moles of water is broken down into 2 moles of hydrogen and one mole of oxygen.

Which of the following processes are physical changes? Mark all
stich3 [128]

The process that is physical changes is:

  • mixing frozen orange juice concentrate with water

<h3>What is a physical change?</h3>

A physical change can be described as a type of  change  that take place in physical without chemical reaction as opposed to chemical change.

They are changes that are  usually reversible it should be noted that physical change do not  involve the alterations  as regards the  chemical make up of a particular  substance  and as a result of this , in physical change, there is   no formation of new product.

Therefore, The process that is physical changes is mixing frozen orange juice concentrate with water
