then go through that pile and keep doing that process for history I make power points your reading and writing the information over again exposing yourself twice or you can YouTube videos on the subject

For me, it depends on the subject. Because I'm weird.
For social studies related classes, usually just reviewing facts is enough to let me get good test/quiz scores.
For science classes, I review the topics that I had the most trouble with, because science comes naturally to me, so the rest is easy.
For math, since I struggle with that the most, I put the most study time into it. I take whatever topics from the class that confused me most, and just do random problems related to that topic. This actually helps a great deal.

A 20.38 gram sample of cobalt is heated in the presence of excess sulfur. A metal sulfide is formed with a mass of 31.47 g. Dete

Viefleur [7K]

Answer: The empirical formula of the metal sulfide is $CoBr_{2}$ .

Explanation:

Given: Mass of metal = 20.38 g

Mass of metal sulfide = 31.47 g

Moles is the mass of a substance divided by its molar mass.

So, moles of cobalt (molar mass = 59 g/mol) are as follows.

$Moles = \frac{mass}{molarmass}\\= \frac{20.38 g}{59 g/mol}\\= 0.345 mol$

Moles of bromine (molar mass = 80 g/mol) are as follows.

$Moles = \frac{(31.47 - 20.38) g}{80 g/mol}\\= \frac{11.09 g}{80 g/mol}\\= 0.138 mol$

Now, the ratio of number of moles of cobalt and number of moles of bromine are as follows.

Moles of Co : Moles of Br = 1 : 2

Hence, the empirical formula is $CoBr_{2}$ .

Thus, we can conclude that the empirical formula of the metal sulfide is $CoBr_{2}$ .

Which two reactants make Calcium carbonate?

Norma-Jean [14]

Impossible to form from given reactants

Explanation:

Only sodium has carbonate ion here .so only possible way to displace carbonate is to use potassium

When sodium carbonate and Potassium iodide react with each other double displacement reaction occurs

As potassium is powerful than sodium it displaces sodium to form potassium carbonate .

Then you have to use water and then you can use calcium suppliment .

Which of the following is true concerning y? A) wdescribes the probability of finding an electron in space. B) ya describes the

earnstyle [38]

Answer:

wdescribes the probability of finding an electron in space.

Explanation:

The quantum mechanical model of the atom assigns wave properties to the electron. This is in accordance with Heisenberg's uncertainty principle.

The probability of finding the electron in a given volume element is given as the square of the wave function while the wave function itself does not really have a physically significant meaning.

However, the wave function is a mathematical function that contains a detailed information about the behavior of an electron.
