Answer: This law is sometimes referred to as the 'Avogadro's Hypothesis' or 'Avogadro's Principle'. This is an experimnetal gas law that is relating to the volume of gas to the amount of substance of gas that is present to the state. This law also states that ''Equal volumes of all gases, at the same temp. and pressure, have the equal amount of molecules.''.
I hope this helps you and good luck! ☺
Answer:
With the appropriate security measures nuclear power, as well as other energy sources, can be used safely.
Explanation:
Nuclear energy, as well as other energy sources, can be dangerous if we do not take the appropriate prevention and protection measures. <u>Nuclear power has one of the lowest levels of fatalities per unit of energy generated, as well as low levels of air pollution-related deaths and allows the reduction of carbon dioxide emissions compared to other energy sources.</u> <em>Since its commercialization, in the 70s, the number of nuclear power accidents is very low compared to the number of accidents of other energy sources, having that </em><em>coal mining is the most dangerous energy activity in history.</em><em> </em>
I think that without the correct security considerations, all the energy sources can be dangerous, but if we take security measures as using protection barriers, controlling the reactivity of nuclear power plant, making regularly quality and prevention test control, as well as other measures, we can have the benefits of the nuclear power without worrying too much for danger.
Therefore, with the appropriate security measures nuclear power, as well as other energy activities, can be used safely.
I hope it helps you!
Answer:
The force of gravity on earth is always equal to the weight of the object as found by the equation: Fgrav = m * g where g = 9.8 N/kg (on Earth) and m = mass (in kg) (Caution: do not confuse weight with mass.) The normal force is the support force exerted upon an object that is in contact with another stable object.
Explanation:
FeS known as iron sulphide is formed by the following reaction:
Fe + S ................><span> FeS
</span>
Iron sulphide has a molar mass of 87.910 grams. It has a grey color and can either be in the form of a powder of in the form of lumps.
It is insoluble in water and it reacts with acids.
Its density is 4.84 g/cm^3 and it has a melting point of 1194 degrees celcius.
Answer:
Explanation: Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. Hope that helps!
