The allowable concentration level of vinyl chloride, C2H3Cl, in the atmosphere in a chemical plant is 2.0 x 10-6 g/L. a. How many moles of vinyl chloride in each liter does this represent?

Answers

Answer 1

Answer:

3.2x10⁻⁸ moles of vinyl chloride per liter

Explanation:

The concentration of C₂H₃Cl is 2.0x10⁻⁶g/L. To find moles per liter we need to convert this mass to moles using molar mass of vinyl chloride:

Molar mass C₂H₃Cl:

2C = 2*12g/mol = 24

3H = 3*1g/mol = 3

Cl = 1*35g/mol = 35

Molar mass = 35g/mol + 3g/mol + 24g/mol = 62g/mol

2.0x10⁻⁶g * (1mol / 62g) =

3.2x10⁻⁸ moles of vinyl chloride per liter

In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal's home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.!!!!!!!

1. Calculate the density of a liquid that has mass of 14.0g and volume of 18.0 cm? Will this liquid float on
top of water or will it sink? (Density of water is 1.0 g/mL)
I

Answers

formula for density of liquid = mass ÷ vol

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³ ( 5sf)

= 0.778 g/cm³ ( 3sf )

18.0 cm³ is the same as 18.0 ml

Therefore, the liquid will float on water as the water is denser than the liquid.

18.0 cm³ is equivalent to 18.0 ml, in light of the fact that water is denser than liquid, the liquid will float on it.

What is the density of a liquid?

Density is defined as d = M/V, where M stands for mass and V for volume. The unit of density that is most frequently used is grams per cubic centimeter.

The formula for liquid density is mass divided by volume.

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³

= 0.778 g/cm³

The same procedure used to determine a solid's density is used to determine a liquid's density. Calculate the fluid's mass, then its volume, then divide mass by volume.

To determine the fluid's mass, weigh the fluid in the container, pour it out, weigh the empty container, and then subtract the empty container's mass from the mass of the filled container.

Therefore, in light of the fact that water is denser than liquid, the liquid will float on it.

How many lone pairs of electrons are represented in the Lewis structure of a nitrate ion (NO3-)?​

Answers

Answer: 8

Explanation: just took the mastery test

The formation of molecule can easily be shown by drawing Lewis dot structure. Since atom's Lewis dot structure has three dots. Therefore, eight  lone pairs of electrons are represented in the Lewis structure of a nitrate ion (NO₃⁻).

What is Lewis dot structure?

Lewis dot structure is a way to represent the valence electron of an element in the form of dot. These are mainly beneficial in understanding the chemical formula of covalent compound.

3 oxygen (O) atoms and a nitrogen (N) atoms make up basic Lewis dot of a nitrate [NO₃]⁻ ion. The molecular ion has a nitrogen (N) atom in its core and three oxygen (O) atoms, one on each side, at terminal positions.

What is the first step in cell division?

Answer:

Explanation:

during which the nucleus dissolves and the chromosomes begin migration to the midline of the cell.

The first step of cell division is known as prophase, during which the nucleus dissolves and the chromosomes start the migration to the cell.

What is cell division?

Cell division can be described as the process by which a parent cell divides into two daughter cells. Cell division takes place as part of a cell cycle in which the cell grows and replicates chromosome(s) before dividing.

In eukaryotes, there are two types of cell division: a vegetative division (mitosis), producing daughter cells genetically similar to the parent cell, and a cell division that forms haploid gametes for sexual reproduction (meiosis), decreasing the number of chromosomes from two of each kind in the diploid parent cell to one of each kind in the daughter cells.

The phases of cell division are interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

In the Prophase,  the nuclear envelope will be broken down and chromatin condenses to produce shorter more visible strands known as chromosomes.

If a reaction occurs and there were 10 g of Ca
reacting with 20 grams of water, and 5 grams of H2
was produced, how much Ca(OH)2 was produced?
Show your work.
Ca + H2O - Ca(OH)2 + H2

Answers

Answer:

18.52g

Explanation:

(relative atomic masses: H = 1.01, O = 16.00, Ca = 40.08)

Equation (balanced):

Ca + 2H2O -> Ca(OH)2 +H2

First, calculate the number of moles of 10g calcium

No. of moles of Ca  = 10/40.08 = 0.25 mol

Then, calculate the  number of moles of 20g water

No of moles of H2O = 1.11 mol

According to the balanced equation, 1 mole of calcium reacts with 2 moles of H2O completely.  Therefore, H2O is in excess.

So, 1 mole of calcium reacts with water to form 1 mole of Ca(OH)2 (according to the mole ratio shown in the balanced equation)

Therefore, 0.25 mol of Ca(OH)2 is produced.

Mass of Ca(OH)2 produced = no. of moles x molar mass = 0.25 x (40.08 + 16 + 16 + 1.01 + 1.01) = 18.52g
