The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

a. Identify the type of reaction shown:
Li + CaCl2 ---> LiCl + Ca
Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".

Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?
Answer:
Explanation:
The responding variable always is measured against the variable that you have control over.
In this case, you have control over the volume of air.
The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?
Answer:
500 hits
Explanation:
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?
Solution:
Given that:
20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz
10 webs = 1 futz; hence:
1 web = 1 web * 1 futz / 10 webs = 0.1 futz
1 web = 0.1 futz
1 futz = 2 geese; hence:
0.1 futz = 0.1 futz * 2 geese / 1 futz
0.1 futz = 0.2 geese
Therefore, 1 web = 0.1 futz = 0.2 geese
1 web = 0.2 geese
This means that 20 hits = 1 web = 0.2 geese
20 hits = 0.2 geese
5 geese = 5 geese * 20 hits / 0.2 geese
5 geese = 500 hits
During spontaneous fission, a nucleus of 25498Cf can produce 11846Pd, four neutrons, and what other nuclide?
Answer: 52Te - Tellurium
Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.
In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.
The reaction spontaneous fission of Cf is represented below.
25498Cf ⇒ 11846Pd + 4n + X
The characteristics of each element of the equation are:
1) The element Cf has atomic mass 254 and atomic number 98.
2) Element Pd has atomic mass 118 and atomic number 46.
3) Neutron is represented as n, has no atomic number and atomic mass 1.
Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.
At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is
98 - 46 + 0 = 52
In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.
The other nuclide for the spontaneous fission is Tellurium (Te).

Answer:

Help out please????
Answer:
B. X= Elements, Y= Compounds
Explanation:
An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.
Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.
