Answer:
2
Explanation:
because on the product side you have 2 sulfurs so you need 2 on the reactant side.
Answer:
Chemical, electrical, thermal, & radiant
Explanation:
A battery is a device that stores chenical energy and converts it to electricity. The diagram portrays said electricity powering an incandescent light bulb, which work by using an electrical current to heat a filament until light is produced.
For this, you need to know 1) the mass of the hydrate and 2) the mass of the anhydrous salt. Once you have both of these, you will subtract 1) from 2) to find the mass of the water lost.
From the problem, you know that 1) = 2.000 g.
Now you need to find 2). You know that your crucible+anhydrous salt is 5.022 g. To find just the anhydrous salt, subtract the mass of the crucible (3.715 g).
1) = 5.022 g - 3.715 g = 1.307 g
Now you can complete our original task.
Mass H2O = 2) - 1) = 2.000 g - 1.307 g = 0.693 g.
3 *0.75 = 2.25 mol that’s is ur answer for this question
Alpha decay represents the forceful ejection of two protons and two neutrons from the nucleus of the parent atom. If 214 Po undergoes alpha decay, the equation would be:
214 Po ➡️ 210 Pb + 4 He + energy
Alpha decay is in the form of a helium nucleus, two protons and two neutrons.
