Which best represents the reaction of calcium and zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc? Ca → ZnCO3 + CaCO3 → Zn Ca + ZnCO3 → CaCO3 + Zn CaCO3 + Zn → Ca + ZnCO3 CaCO3 + Zn + Ca → ZnCO3
Answer:
Ca + ZnCO3 → CaCO3 + Zn
Explanation:
Ca + ZnCO₃ = CaCO₃ + Zn
Ca + ZnCO3 → CaCO3 + Zn is the answer.
Here Ca and ZnCO₃ are reactant and CaCO₃ and Zn are product . Reactants are written on the left side of equation and product are written on the right side.
Answer:
The correct option is, Ca + ZnCO3 —> CaCO3 +Zn

The attractive force between two objects that depends on their masses and the distance between them is _______?
Answer:
gravitational force
Explanation:
an object with mass attractive another object with mass
ANSWER:
GRAVITATIONAL FORCE
EXPLANATION :
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

The table provided shows data collected during an experiment .
Which of the following claims is supported by the data?
A. Gravitational force are proportional to the masses of the two objects.
B. Gravitational forces are strongest between objects with identical masses.
C. Gravitational forces are weakest when one object is more massive than the other.
Answer:
Explanation: the table shows during an experiment
Gravitational forces are strongest between objects with identical masses, claims are supported by the data. Option B is correct.
What is Newton's law of gravitation?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
When mass increases and distance reduces, gravity rises. Gravity also lowers when the distance between two points grows and the mass decreases.
From the table, it is observed that gravitational forces are strongest between objects with identical masses, claims are supported by the data.
Hence, option B is correct.

what is the definition of the word amplitude
Explanation:
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.

Living things are highly organized and structured, following a hierarchy that. A molecule is a chemical structure consisting of at least two atoms held In larger organisms.
What is Living organisms?Cells combine to make tissues, which are groups of An organ system is a higher level of organization that consists of functionally related organs.
The fact that all living things are composed of cells—which are regarded as the foundation of life—is what first distinguishes them from other types of organisms. The remarkable thing about cells is that, despite their small size, they can join together to build extremely vast structures.
Multicellular organisms are extraordinarily sophisticated creatures with amazing cellular organization. This organization starts deep within your DNA and reaches all the way up to you as an individual.
Therefore, Living things are highly organized and structured, following a hierarchy that. A molecule is a chemical structure consisting of at least two atoms held In larger organisms.

A ball has 17 J of kinetic energy and its mechanical is 25 J
If the ball has a mass of 3.2 KG what is it’s height above ground?
Answer:
0.255m
Explanation:
The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.
What is kinetic energy ?Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.
The sum of kinetic and potential energy of the object is called its mechanical energy.
given Ke of the ball = 17 J
mechanical energy = 25 J
then potential energy = 25 J - 17 J = 8 J.
We have the relation between potential energy, mass and height h as :
p = mgh .
given the mass m = 3.2 kg
g = 9.8 m/s²
then, h = p / (mg)
h = 8 J / (3.2 kg× 9.8 m/s² )
= 0.25 m.
Therefore, the height of the ball above the ground is 0.25 m.

In a chemical reaction,sodium sulphate and barium chloride are mixed to form barium sulphate(a precipitate)and sodium chloride. (i)What are the reactants in the above reaction? (ii)What are the products?
Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
