Answer:

It is a obsessive eating disorder. Where one eats over the average amount and then makes themselves vomit. This is called purging. It is one of 3 main eating disorders. It is a very complex and misunderstood disease. One typically confuses it with binge eating or anorexia.

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize

Rina8888 [55]

Answer:

Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.

So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.

Equation: $P_{1} V_{1} = P_{2} V_{2}$

Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.

So basically Temperature and volume are directly proportional.

Equation: $\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }$

Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.

Basically, Temperature and Pressure are directly proportional.

Equation: $\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }$

Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.

Meaning the moles (amount of gas) is directly proportional to volume.

Equation: $\frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} }$ (n stands for moles)

There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.

Metallic bonds are responsible for many properties of metals such as conductivity true or false?.

Alex17521 [72]

It is true that metallic bonds are responsible for many properties of metals such as conductivity.

Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

Metallic bond increace electrical and thermal conductivity.

How many grams of aluminum hydroxide are obtained from 13.7 g of aluminum sulfide??

Vladimir [108]

<span>For that we need to know something about the chemistry aluminum sulfide and aluminum hydroxide. Aluminum sulfide will react with water to make insoluble aluminum hydroxide and hydrogen sulfide gas. Therefore, we need a balanced chemical equation.

Al2S3(s) + 6HOH --> 2Al(OH)3(s) + 3H2S(g)
17.7g ........................ ???g

17.7g Al2S3 x (1 mol Al2S3 / 150.3 g Al2S3) x (2 mol Al(OH)3 / 1 mol Al2S3) x (78.0g Al(OH)3 / 1 mol Al(OH)3) = 18.4 g Al(OH)3 ...... to three significant digits.</span>

If equal masses of each substance absorb the same amount of heat, which substance undergoes the greatest temperature change

Minchanka [31]

Answer:

See explanation

Explanation:

The heat capacity of a substance is determined by the chemical composition of the substance and its mass.

Now, if substances have equal masses, the substance with the lesser heat capacity undergoes the greater temperature change.

Hence, among the substances, the particular one with the lowest heat capacity is expected to undergo the greatest temperature change.
