A simple circuit consists of a battery to provide power, wires to carry the electrical power, and
load that uses the electrical power for example a light globe

Answer:
The amount (mass) of water we will have is 17.869 grams
Explanation:
The molar mass of hydrogen gas H₂ = 2.016 grams/mole
The molar mass of oxygen gas = 31.999 g/mol
Therefore, 2.00 g of hydrogen will give;
2.00/2.016 = 0.9921 moles of H₂ gas and
15.87 g of O₂ will give;
15.87/31.999 = 0.49595 moles
The reaction is as follows;
2H₂ (g) + O₂ (g) → 2H₂O (l)
Two moles of H₂ react with one mole of O₂ to produce two moles of H₂O
Therefore 0.9921 moles of H₂ will react with 0.9921/2 or 0.49595 moles of O₂ to produce 0.9921 moles of H₂O
From the above we note that all the H₂ and O₂ are completely consumed to form 0.9921 moles of H₂O
Molar mass of H₂O = 18.01528 g/mol
Number of moles = Mass/(Molar mass)
∴ Mass of H₂O = (Molar mass) × (Number of moles)
= 18.01528 g/mol × 0.9921 moles = 17.869 grams
Therefore the amount (mass) of water we will have = 17.869 grams.
I believe the answer is <span>can be elements or compounds
In this case, elements in the decomposition reaction is the substance that cannot be separated into simpler substances.
Compounds, technically act as a reactant in the decomposition reaction, but since the reaction breakdown one substance into two or more, sometimes it exists in the product.</span>
<u>Answer:</u>
Nitrogen gas be a mineral only, if it is in organic forms.
<u>Explanation:</u>
Most of the forms of organic nitrogen is not be taken by plants, with the exception in the form of small organic molecules. Also plants can promptly take the nitrogen when it is in other forms like ammonia and nitrate.
The microorganisms in the soil converts the organic forms of nitrogen to mineral form when they decompose organic matters and also fresh plant residues. This type of process is called mineralisation.
Answer:
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Gravitational energy or gravitational potential energy is the potential energy a massive object has in relation to another massive object due to gravity. It is the potential energy associated with the gravitational field, which is released when the objects fall towards each other.
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
