Complete the sentences to identify the difference between a nonmetal atom and its anion.
In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.
In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.
key bank:
- a positive
- no net
- electrons
- protons
- a negative
- neutrons
Answer:
more protons than neutrons and the number of electrons and blank are blank
Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

Kiley wants to balance the equation H2 + N2 → NH3. Which would be her first step in balancing an equation?
Answer: The balanced equation will be
6H2 + N2 → 2NH3
Explanation:
First step is to balance nitrogen
ie, H2 + N2 → 2NH3
Second step is to balance hydrogen accordingly
ie, 6H2 + N2 → 2NH3

How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
Please don't just give the sample response.
Answer:
The food coloring mixes much faster in the hot water than it mixes with the cold water. This is because in the hot water, water molecules have more energy and are moving faster than the molecules of cold water.

A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42
Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42
Newtons. With what force does the scale push back up against her feet?
Answer:
The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

B) Cu(s)
C) Sn(s)
D) Zn(s)
Answer:
THE answer IS B)cu(s)
Explanation:
HOPE ITS HELP
The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

Explain why higher temperature in a substance does not mean the substance has more thermal energy?
Answer:
Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.
Explanation:
If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.
Which unit conversion allows you to convert 21.0 gallons into milliliters?
Some English and English-metric unit relationships: 1 liter = 1.057 quarts, 1 gallon = 4 quarts
Answer:
Explanation:
we are given
there are in 0.073 gallons
we can see that there are two non-zero places after decimals
so, there are two siginificant figures
step-1: Change gallons to quarts
we know that
1 gallon = 4 quarts
so, we can write as
step-2: Change into liter
we know that
1 liter = 1.057 quarts
or
step-3: Change into millilitre
we know that
Since, it is asking for only two significant figures
so, we can also write as
