The sum of any number and its additive inverse gives the additive identity.
Additive Identity is a number that when added to any other number does not change it value. Eg. 2 + 0 = 2
Hence 0 is the additive identity for all numbers
Additive Inverse of 6 = (- 6)
Hence 6 + (- 6 )
= 6 - 6
= 0
The sum of 6 and its additive inverse is 0

When iodobenzene codistills with water at 760 toor, the boiling point of the mixture is 98.5. the vapor pressure of water is?

katrin [286]

This was one of the old regents. I didn't get this at first glance too so I searched for it and I got this site. lol. I know what to do now. To get a higher boiling point, you have to find which solution has the most moles. Since SO4, PO4, and NO3 are all polyatomic ions, they only count as one mole.

Explanation:

Step 1: Define

0.200 mol H₂S

Step 2: Identify Conversions

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of H₂S - 2(1.01) + 32.07 = 34.09 g/mol

Step 3: Convert

Set up: $\displaystyle 0.200 \ mol \ H_2S(\frac{34.09 \ g \ H_2S}{1 \ mol \ H_2S})$
Multiply: $\displaystyle 6.818 \ g \ H_2S$

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

6.818 g H₂S ≈ 6.82 g H₂S

Consider the reaction below.

SpyIntel [72]

Water is an amphoteric compound. This means it could be a base or an acid, depending on the substance it is to be reacted with. In this case, water is a base because HF is an acid. Now, if the reactant is an acid, its form after the reaction is called the conjugate pair. Since HF became F⁻, the acid-conjugate base pair is: HF and F⁻.

a) Provide equation of K of this reaction, use symbol " ^ " for exponents. That means 1000 = 10^3 and 1/100 is 10^(-2). b) How m

stealth61 [152]

Answer and Explanation:

a. The equation of K of this reaction is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

$K = \frac{(D)^5 (E)^7 (F)}{(A)^3 (B)^5 (C)^4}$

b. The moles of compound F is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

2 moles

Now, the mole of produced is

$= \frac{1}{4} \times \ moles\ of\ c$

Now, we will the value of c by using the above equation

$= \frac{1}{4} \times 2$

After solving the above equation we will get

0.5 moles

One unusual characteristic of water is its high specific heat, which means that water __. Multiple select question. warms or coo

Rus_ich [418]

The high specific heat of water means that water absorbs a great amount of heat before its temperature changes.

<h3>Specific heat capacity of water</h3>

Specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C).

There are substances that has low Specific heat capacity for example metals like iron while some other substances have high specific heat capacity like water.

The high specific heat capacity seen in water means that it takes more energy to increase the temperature of water compared to other substances.

Therefore, the high specific heat of water means that water absorbs a great amount of heat before its temperature changes.
