which two elements are most likely to have similar physical properties?
pls help:)
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, sodium and potassium are the two element most likely to have similar physical properties.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The chances are high that sodium and potassium share both physical and chemical characteristics. They are both members of the Alkali metals family. Both are extremely reactive and share the same valence electrons. The elements in the same group have same physical and chemical properties.
Therefore, sodium and potassium are the two element most likely to have similar physical properties.

The organic compound chloroform, which has the molecular formula [tex]CHCl_3[/tex], is well known for its use as a solvent and anaesthetic. It consists of three chlorine atoms (Cl), one hydrogen atom (H), and one carbon atom (C).
The molar mass of carbon (C) is approximately 12.01 g/mol, the molar mass of hydrogen (H) is approximately 1.01 g/mol, and the molar mass of chlorine (Cl) is approximately 35.45 g/mol. We add up the molar masses of all the individual atoms to determine the molar mass of [tex]CHCl_3[/tex]:
(1 * molar mass of C) + (1 * molar mass of H) + (3 * molar mass of Cl)
(1 * 12.01 g/mol) + (1 * 1.01 g/mol) + (3 * 35.45 g/mol)

oxygen wants to lose two electrons which results in a +2 charge. is that true or false
Answer:
false
Explanation:
electronic configuration of oxygen is 2,6 that means it has 6 electrons in its last shell. but it can hold 8.so it is unstable so to be stable oxygen needs another 2 electrons so that it becomes 8 ( 6 + 2 = 8 )
so oxygen takes 2 electrons which result in -2
i dont understand this i cant think :These ions have the same stable electron configuration as the noble gas helium. All Group 1 atoms can lose one electron to form positively charged ions. ... Elements in Groups 15,16 and 17, find it easier to gain electrons than lose them.
Answer:
Li atoms readily give up one electron to form positively charged, Li+ ions. These ions have the same stable electron configuration as the noble gas helium. All Group 1 atoms can lose one electron to form positively charged ions.
Explanation:
I DON'T KNOW IF THIS IS THE RIGHT ANSWER BUT I'M TRYING TO JUST ANSWER.
Answer:
Explanation:
-We know that an atom is table if they have 8 valence electrons (like noble gases, they are stable)
-Group 1 atoms only has 1 valence electron, in order to become stable, they are desperately wanted to lose that one valence electron to become stable.
-While group 15 has 5 electrons, it is easier for them to gain 3 electrons to become 8 electrons than losing all 5 electrons.
-the same thing for group 16 has 6 valence electrons and 17 has 7 electrons. It is easier for them to gain 2 and 1 more valence electrons to become stable.

To solve this we must be knowing each and every concept related to solar energy. Therefore, the correct option is option D among all the given options.
What is solar energy?Sun energy is the term for solar radiation that may create heat, trigger chemical processes, or create electricity. The total solar energy incidence on Earth is far greater than the global energy needs at the now and in the future.
Although sunlight is unquestionably the most potent energy source that Earth receives from the Sun, its intensity at the surface of the planet is really rather modest.

A forklift applies a force of 2,000 N to raise a box 3 m.
How much work is done by the forklift in raising the
box?
If the force is applied to lift the box, then there is no work done as the displacement of the box is not in the same direction of the box.
However, if the force is being applied to move the box in the direction of the force, then the work done is:
Work = force x distance
Work = 1500 x 3
Work = 4,500 Joules
A forklift applies a force of 2,000 N to raise a box 3 m. The work is done by the forklift in raising the box is 6000 Joules.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity, since it has both magnitude and direction.
Isaac Newton's three laws of motion, which are outlined in his Principia Mathematica, are frequently used to illustrate the concept of force (1687).
Contact forces and act at a distance forces are the two different types of forces. Your daily use of force is evident. Basically, push and pull are forces. You exert force on an object when you push against it or pull against it.
The force is applied to move the box in the direction of the force,
Then the work done is
Work = force x distance
Work = 2000 x 3
Work = 6000 Joules.
Thus, A forklift applies a force of 2,000 N to raise a box 3 m. The work is done by the forklift in raising the box is 6000 Joules.

5.00 g zinc added to hudroclric acid what is the mass of hydrogen gas
Answer:
0.15g
Explanation:
Given parameters:
Mass of Zn = 5g
Unknown:
Mass of hydrogen gas = ?
Solution:
To solve this problem, we must first write the reaction expression;
Zn + 2HCl → ZnCl₂ + H₂
Now find the number of moles of the known specie which is Zn;
Number of moles of Zn = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of Zn = 65.4g/mol
Number of moles of Zn = [tex]\frac{5}{65.4}[/tex] = 0.08mole
1 mole of Zn will produce 1 mole of H₂
0.08 mole of Zn will give 0.08 mole of H₂
Mass of H₂ = number of moles x molar mass
molar mass of H₂ = 2(1) = 2g/mol
Mass of H₂ = 0.08mol x 2g/mol = 0.15g
