B. potassium
C. hydrogen
D. lithium
Answers
Answer: C. hydrogen
Explanation:
Atomic radius of an atom is defined as the total distance from the nucleus to the outermost orbital of electron.
On moving from top to bottom, there is an addition of shell around the nucleus and the outermost orbital gets far away from the nucleus and hence, the distance between the nucleus and outermost orbital increases.
This in turn increases the atomic radii of the element from moving top to bottom in a group.

According to one acid-base theory, the H2O molecule
(1) accepts H+ ions (3) donate H+ ions
(2) accepts OH- ions (4) donates OH- ions
Answers
The statement, that describes acid-base theory in which the H2O molecule is "accepts ions."
What is an acid-base theory?
An acid is a compound that accepts a pair of electrons. A base is a generator of electron pairs. This is the broadest theory of acids and bases. Water can serve as both an acid and a base in solution, and it can also be both an acid and a base to itself. Water takes hydrogen ions and behaves as a base when coupled with an acid. When water is combined with a base, it gives hydrogen ions and so behaves as an acid. Using the balanced equation, the water molecule acts a acid which accepts the hydrogen ion. to form hydronium ion.
Hence the correct option is 1.

Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
Chemical equation:
MgCl₂ + Li₂CO₃ → MgCO₃ + 2LiCl
? + 75 g = 135 g + 34 g
The mass of reactant and product must be equal. That's why,
135+ 34 = 169 on product side
94 + 75 = 169 on reactant side
MgCl₂ + Li₂CO₃ → MgCO₃ + 2LiCl
94 + 75 g = 135 g + 34 g
169 g = 169 g

Answer:
Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.
If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.
If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.

All substances are matter but all matters are not substance. Matter is generally a loose term used in respect to a substance. Matter and substance are sometimes used for the same context, this is certainly not correct. Various examples have already proved that a matter will not always be a substance depending on its physical nature, but a substance is always a matter.
