Answer:
Both have infinite range i believe
Explanation:
The four fundamental forces are arranged in the increasing order of their relative strength. Then both have infinite range. Therefore, option B is correct.
What is relative strength ?A ratio of a stock price performance to a market average performance is called relative strength. In technical analysis, it is employed. It shouldn't be mixed up with the relative strength index.
Calculating the relative strength comparison indicator requires dividing the price of one asset by the price of another security (the "base" security). The ratio, or relationship, between the two securities, is the outcome of this split.
A classic example of a relative strength activity would be gymnastic movements requiring only the client's body weight. It is likely that clients who have a suitable amount of relative strength are less exhausted and more effective in shifting their body weight in space.
Thus, option B is correct.

Answer:
Magnesium has valency equal to 2 +
Explanation:
because the electronic configuration of Mg is [2,8,2]. The nearest noble gas to magnesium is neon with electronic configuration of [2,8], to achieve this stable electronic configuration Mg can lose 2 valence electrons, hence its valency is 2 + .
Write the isotope notation for an element with 5 protons and 6 neutrons.
The isotope notation : [tex]\large {{{11} \atop {5}} \right X}[/tex]
Further explanationGiven
53 protons and 20 neutron
Required
The isotope notation
Solution
Isotopes are elements that have the same atomic number with a different mass number
The following element notation,
[tex]\large {{{A} \atop {Z}} \right X}[/tex]
X = symbol of element
A = mass number
= number of protons + number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
So the mass number of element = 5 + 6 11
Atomic number = 5
The symbol :
[tex]\large {{{11} \atop {5}} \right X}[/tex]
if input energyis 100J and useful is 70J what is the waste energy
Answer:
waste energy = 30 J
Explanation:
Given that.
Input energy = 100 J
Useful energy = 70 J
We need to find the amount of waste energy.
Waste energy = total energy - used energy
= 100 J - 70 J
= 30 J
Hence, 30 J of energy is waste energy.
the law of conservation of mass states_____
a) matter can be created and destroyed but does not change forms
b) the mass of all substances present before a chemical change equals the mass of all the substances remaining after the change
c) in a chemical reaction, efforts should be made to preserve rare elements without changing them.
d) in a chemical reaction, the final mass of the products is always greater than the starting mass of the reactants.
Answer:
B
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction
True or false: Atoms and mass are conserved in nature
True
False
Answer:
It’s true
Explanation:
If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system. ... The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth.

How does energy change matter?
Answer:
Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

A balanced chemical equation is a direct presentation of the ___________.
law of conservation of momentum
law of conservation of energy
law of conservation of mass
ideal gas law
The law of conservation of mass is directly represented in a balanced chemical equation.
What is the law of conservation of mass?In chemistry, the law of conservation of mass says that in a closed or isolated system, matter cannot be created or destroyed in a chemical reaction.
For example: If we burn wood, the mass of ashes and gases is equal to the mass of wood before burning.
Thus, the Law of conservation of mass represent a balanced chemical equation.

In the reaction below, how would adding more of product C affect the equilibrium of the
system?
A + B 2 C + D (2 points)
VE
Shift it to the right toward the products.
M
Shift it to the left toward the reactants.
Pr
Equally create more products and reactants.
Da
Ро
It would have no effect.
Answer:
Shift it to the left toward the reactants
Explanation:
The direction of movement of a reaction at equilibrium has been explained by a man called HENRY LOUIS in his principle. According to this principle, a reaction will shift in response to a stress on equilibrium. The stress can either be effects of temperature, pressure, concentration etc on the reaction equilibrium.
- An addition of a reactant or product will cause the reaction to shift towards the opposite direction of the substance added. For example, in this question, the following reaction was given:
A + B ----> C + D
C is a product, meaning that if more of product C were added to this reaction, the reaction will shift towards the left (reactant side) because there are now more products. In other words, the reactants will be favored if there is an increase in the concentration of the products.

Which is a characteristic of all ions?
They are metals.
They have a charge.
They are made of two or more types of atoms.
They form chemical bonds through electron sharing.
Answer:
D. They form chemical bonds through electron sharing.
Explanation:
The correct characteristic of all ions is that they have a charge. Therefore option B is correct.
An ion is an atom or a molecule that has gained or lost electrons, resulting in an unequal number of protons and electrons. This imbalance of positive and negative charges gives the ion a net electrical charge.
Ions can have a positive charge (called cations) if they have lost electrons, or a negative charge (called anions) if they have gained electrons.
The charge of an ion is essential in determining its behavior and interactions with other ions and molecules. It influences the way ions form chemical bonds and participates in chemical reactions.
The charge of an ion is indicated by a superscript after the chemical symbol, such as Na+ for a sodium cation or Cl- for a chloride anion.

Further explanationGiven
Reaction if Na₂S + HCl
Required
Type of reaction
Solution
The double replacement reaction occurs when there is a displacement of the cations and anions of the reactants involved in the reaction to form two new compounds.
The general formula for this reaction :
AB + CD ⇒ AD + CB
At the bottom of the reaction, it is shown the number of atoms of each compound in the reactants and products which indicates the application of the law of conservation of mass, that the number of atoms in the reactants will be the same as the number of atoms in the product, so the reaction is said to be in a balanced state.
