When there are 165.0grams of reactants, what is the mass of the products for that reaction?

Chemistry

vfiekz [6]3 years ago
3 0

Answer:

165.0 grams

Explanation:

The law of conservation of mass tells us that the mass of the reactants will be equal to the mass of the products. Therefore, if we begin with 165.0 grams of mass, that is how much there will be at the end in the products, even if it's in different forms.

Lewis structure for nitrogen triiodide, NI(3)
Rasek [7]

Answer:

Lewis structure for nitrogen triiodide,NI_3 is given in the attachment.

Explanation:

Given:

The given compound is Nitrogen triiodide. In which 1 atom of Nitrogen combines with 3 atoms of Iodine. Both Nitrogen and Iodine are non-metals,So they form covalent bond by sharing of electrons.

The electron configuration of Nitrogen and Iodine is given below;

N(7) = 1s^2,2s^22p^3\\I(53) = 1s^2,2s^22p^6,3s^23p^63d^{10},4s^24p^64d^{10},5s^25p^5

There are 5 electrons in valance shell of Nitrogen atom and 7 electrons in valance shell of Iodine atom.

So, 3 atom of Iodine shares 1 electron with 1 electrons of Nitrogen.

The Lewis dot Structure is in the attachment.

When a pot of water has been boiling vigorously for several minutes, the bubbles that emerge from the liquid water are composed
kumpel [21]
Well, water is composed H2 gas and O2 gas in a 2:1 ratio, and the bubbles that form at the bottom of the pan is just the water changing from a liquid to a gas, and im pretty sure its water vapor that comes out of the pan. I hope that helped??? :)

This patient has a bone density of 820mg/cm3. What is the volume of a 25g sample?
mamaluj [8]

<u>Answer:</u> The volume of bone for given sample is 30.49cm^3

<u>Explanation:</u>

To calculate volume of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of bone = 820mg/cm^3=0.82g/cm^3      (Conversion factor:  1 g = 1000 mg)

Mass of bone = 25 g

Putting values in above equation, we get:

0.82g/cm^3=\frac{25g}{\text{Volume of bone}}\\\\\text{Volume of bone}=30.49cm^3

Hence, the volume of bone for given sample is 30.49cm^3

How many electrons can the 5th shell hold? 8 18 24 32 50
krok68 [10]

Each shell contains a fixed number of electrons. The general formula of the number of electrons can be hold in n-th shell is 2n². 5th shell can hold 2x5² = 50  number of electrons.

1st shell contains 2 X 1²= 2 number of electrons, 2nd shell contains 2 X 2²=8 number of electrons, 3rd shell contains 2 X 3²=18 number of electrons, 4th shell contains 2 X 4²=32 number of electrons,  5th shell contains 2 X 5²=50 number of electrons and so on.

Foods that are high in carbohydrates have the least impact on slowing the body's absorption rate of alcohol.

What is human digestive system?

The digestive system of the human body is made up of the gastrointestinal tract and additional digestive organs (the tongue, salivary glands, pancreas, liver, and gallbladder). In order for food to be absorbed and incorporated into the body, it must first be broken down into smaller and smaller components during digestion. Cephalic, gastric, and intestine phases make up the three

Our body will immediately start absorbing alcohol when you are hungry. However, because alcohol is not soluble in fat, fatty foods effectively create a barrier through which it cannot easily travel. This will greatly slow down alcohol absorption.

Hence, foods that are high in carbohydrates have the least impact on slowing the body's absorption rate of alcohol.
