Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga
Answers
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Hi, help with these two questions.
1. Write the isotope notation for an atom with 9 protons and an atomic mass of 20.
2. Write the isotope notation for an atom with 13 protons and 12 neutrons.
Answers
Answer:
Answered below
Explanation:
1) Atomic number is usually the number of protons
Since the atom is a neutral atom, Number of protons is equal to the number of electrons.
Thus means that we have 9 electrons and our atomic number is 9.
Atomic mass number is given as 20.
The is topic notation makes use of the atomic number and mass number.
Atomic number of 9 denotes fluorine.
Thus, the isotopic notation is written as attached;
2) we are told that an atom has 13 protons and 12 neutrons.
Similar to A above,
Atomic number is 13.
Now, number of neutrons + number of protons = mass number.
Thus;
Mass number = 13 + 12 = 25
Element with atomic number of 12 is magnesium
Thus,isotopic notation is as attached.

Answers
Answer: C. [tex]2HgO\rightarrow 2Hg+O_2[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The skeletal chemical equation will be:
[tex]HgO\rightarrow Hg+O_2[/tex]
The balanced chemical equation will be:
[tex]2HgO\rightarrow 2Hg+O_2[/tex]
The correctly balanced chemical equation for the reaction [tex]HgO - > Hg + O_{2}[/tex] is: C. [tex]2HgO - > 2Hg + O_{2}[/tex]
The law of conservation of mass states that mass can neither be created nor destroyed; it can only be transferred from one location to another. As a result, the mass of the products is required to be the same as the mass of the reactants.
On both the reactant and product sides of the reaction, the identical amount of atoms of each element is required. Therefore, the equations used in chemistry are balanced.

Which sample would show stronger (intermolecular) attractive forces, the cold water or the hot water?
Answers
Answer:
Cold water
Explanation:
A simple way to solve this kind of problems is to keep in mind that:
Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.
Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.
A 3.5L flexible container holds a gas at 250K. What will the new volume be if the temperature is increased to 400K?
Answers
Answer: 5.6L
Explanation:
Just did it on an assignment
A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.
What is Charles Law ?Charles law is an ideal gas law which states that at a constant pressure volume of a gas is directly proportional to the absolute temperature.
It is expressed as
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]
where,
V₁ = initial volume
T₁ = initial temperature
V₂ = final temperature
T₂ = final temperature
Now put the values in above formula, we get
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]
[tex]\frac{3.5\ L}{250\ K} = \frac{V_2}{400\ K}[/tex]
[tex]V_{2} = \frac{3.5\ L \times 400\ K}{250\ K}[/tex]
[tex]V_{2} = \frac{1400}{250}[/tex]
V₂ = 5.6 L
Thus, from the above conclusion we can say that A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.

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?
Answers
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.
