Answer:
The metal atoms that plate your object come from out of the electrolyte, so if you want to copper plate something you need an electrolyte made from a solution of a copper salt, while for gold plating you need a gold-based electrolyte—and so on

Hello there!
In this case, when we have a gas that is undergoing a change in both pressure and temperature, we utilize the Gay-Lussac's equation as shown below:
Thus, since we are given the initial pressure and temperature and the final temperature, we can compute the final pressure as shown below:
So we plug in, by making sure the temperatures are in kelvins, to obtain:

<h3>Answer;</h3>
= 13.629 g of ZnCl2
<h3><u>Explanation;</u></h3>
The equation for the reaction.
Zn(s)+2HCL(aq)=>ZnCl2(aq)+H2(g)
Number of moles of Zinc;
Moles = mass/RAM
= 6.5 g/65g/mol
= 0.1 moles
The mole ration of Zn : ZnCl2 is 1 : 1
Therefore, number of moles of ZnCl2 is 0.1 moles
Mass = moles × Molar mass
= 0.1 ×136.286 g/mol
<u> = 13.629 g</u>
The simplest way to use the periodic table to identify<span> an </span>element<span> is by looking for the </span>element's<span> name or elemental symbol. The periodic table can be used to </span>identify <span>an </span>element<span> by looking for the </span>element's<span> atomic </span>number<span>. The atomic </span>number of<span> an </span>element<span> is the </span>number of<span> protons found within the atoms of that </span>element<span>.</span>
Answer:
B) The farther away from the Sun, the thinner a planet's atmosphere. Closer planets need more protection from the heat.
Explanation:
The planets closest to the Sun are the inner, or terrestrial, planets and are similar to Earth in some ways. They are rocky and dense, have few moons, no rings, and are relatively small. These planets also differ in many ways, as shown in the chart. For example, Venus is the hottest planet on the chart, even though Mercury is closer to the Sun. The temperature difference between Venus and Earth is significantly greater than the difference between Venus and Mercury, even though Venus lies close to midway between those two planets.
