<span>Salt is the product formed by a reaction in which the hydrogen atoms of an acid are replaced by the atoms of a metal. The salt is formed as a result of the neutralization of the acid by base, that is the metal or positive ion replace the hydrogen ion in the acid. For instance: NaO + H2SO4 = NaSO4 + H2O. In this example, Na [sodium] has replaced the hydrogen in H2SO4, thereby forming the salt NaSO4.</span>
Answer: quilt 22v corona699880100000000000
Explanation:
C because ships and other boats has underwater microphones underwater because on most cargo ships the engine is to loud so they use microphones underwater to detect torpedos so your answer is C
Answer:
Argon
Explanation:
The average kinetic energy of the particles in a gas is given by
where
m is the mass of the particles
v is their rms speed
The average kinetic energy of the particles in a gas can also be written as
where
k is the Boltzmann's constant
T is the absolute temperature of the gas
Combining the two equations,
We can re-write the equation as
We see that:
- The speed is directly proportional to the square root of the temperature
- The speed is inversely proportional to the square root of the mass of the particles
Therefore, if the two gases are at same temperature, the particles will move faster in the gas with lighter particles (smaller mass).
Since Krypton atoms have larger mass than Argon atoms, it means that atoms in Argon move faster than in Krypton.
Firstly, the chemical equation between the calcium metal and water will be:
Ca(s) + 2 H₂O(l) → Ca(OH)₂(aq) + H₂(g)
We can see from the equation the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence calcium floats on water.
The other metal that will float on the water during the reaction is magnesium which have the same chemical behavior like calcium, we can illustrate that by the chemical equation:
Mg(s) + 2 H₂O(l) → Mg(OH)₂(aq) + H₂(g)
