Answer:

Ans B)=====> Dorsal Horn

Two arms, each known as a Dorsal Horn, are formed by the core grey matter at the back of the spinal cord. In the image, the region labeled “ A “ is called the Dorsal Horn. Therefore, option B is correct.

What is dorsal horn ?

One of the gray longitudinal columns discovered inside the spinal cord is the dorsal horn. Through the dorsal roots of the spinal nerves, it predominantly serves as the end of primary afferent fibers.

A complex network of excitatory and inhibitory interneurons, as well as projection neurons, make up the dorsal horn, which serves as an intermediary processing center for this information. It transmits the processed somatosensory information from the spinal cord to the brain.

The cell bodies of sensory neurons are located in the dorsal horns. The ventral horns are two arms of central grey matter that are found at the front of the spinal cord.

Thus, option B is correct.

Does this reaction meet the Law of Conservation of Mass? 2H2 + O2 → 2H2O explain.

Answers

Answer:

yes because on the left side 4 hydrogen in right side 4 hydrogen on the left side 2 oxygen in the right side 2 oxygen

Answer:

The Law of Conservation of Mass states that the mass of the system must remain constant over time as the system's mass cannot change because energy is not created nor destroyed. To tell if a chemical equation meets this law, check to see if the number of atoms is the same on both sides of the chemical equation.

Reactant Side:

4 atoms of Hydrogen2 atoms of Oxygen

Product Side:

4 atom of Hydrogen2 atoms of oxygen.

Remember, when counting the atoms in a equation the subscript is the number that represents the quantity of that specific atom. Subscripts are numbers that come after a symbol and below. If an element does not have a subscript, then it is understood that the subscript is 1.  The coefficent represents the quantity of molecules, the coefficient multiplies everything in the formula.

What is the empirical formula of a compound that is 27.3% carbon, 9.10% hydrogen and 63.6% nitrogen by mass?

Answers

Explanation:

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( Divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54

= 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

Answer is CH4N2

The empirical formula of a compound is [tex]CH_4N_2[/tex]

What is an Empirical Formula?

The empirical formula of a chemical compound is defined as the simplest whole number ratio of the atoms present in a compound.

The empirical formula of a compound defines the simplest ratio of the number of different atoms present. The molecular formula gives the actual number of each different atom present in a molecule. The molecular formula is mainly used which is a multiple of the empirical formula.

Molecular Formula  = n × Empirical Formula

For above given example,

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( We divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54 = 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

FIRST, you need to write down the the correct reaction.  Your equation makes no sense

here is the correct question

2AlCl3 --> 2Al + 3Cl2    If you produce 15 moles of Al, how many grams of AlCl3 decomposed?

for every mole of Al produced, we decomposed a mole of ​AlCl3

so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3

15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed

How do you know how to order an empirical formula?

Answers

Answer:

Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.


Solving Empirical Formula Problems There are two common types of empirical formula problems. Luckily, the steps to solve either are almost exactly the same. Example #1: Given mass % of elements in a compound.
A compound was found to contain 32.65% Sulfur, 65.3% Oxygen and 2.04% Hydrogen. What is the empirical formula of the compound?
1) The first step in this problem is to change the % to grams.
32.65%→32.65g of S
65.3%→65.3g of O
2.04%→2.04g of H
2) Next divide all the given masses by their molar mass.
32.65g of S/ 32gm-1 = 1.0203 moles of S
65.3g of O/ 16gm-1 = 4.08 moles of O
2.04g of H/ 1.008gm-1 = 2.024 moles of H
3) Then, pick the smallest answer in moles from the previous step and divide all the answers by that. Remember that if you calculate a number that is x0.9 round to the nearest whole number
1.0203 moles of S/ 1.0203 = 1
4.08 moles of O/1.0203 = 3.998 ≈ 4
2.024 moles of H/1.0203 = 1.984 ≈ 2
4) Lastly, the coefficients calculated in the previous step will become the subscripts in the chemical formula.
S = 1
O = 4
H = 2
H2SO4
Example#2: Given the mass of a reactant before a chemical reaction and the mass of a product after a reaction.
When 0.273g of Mg is heated in a Nitrogen (N2) environment a chemical reaction occurs. The product of the reaction is 0.378g . Calculate the empirical formula.
1) In any empirical formula problem you must first find the mass % of the elements in the compound. Since the total mass of the final product was 0.378 we find that:
0.378g total-0.273g magnesium = 0.105g nitrogen
0.105g nitrogen/0.378g total (100) = 27.77%
0.273g magnesium/0.378g total (100) =72.23%
2) Then change the % to grams
27.77%→27.77g of N
72.23%→72.23g of Mg
3) Next, divide all the masses by their respective molar masses.
27.77g/14gm-1 = 1.98 moles N
72.23g/24.31gm-1 = 2.97 moles Mg

A 23.6 g sample of an unknown gas occupies a volume of 12.0 L at standard temperature and pressure. What is the molecular mass (molar mass) of this gas?

Answers

The molecular mass (molar mass) of this gas is equal to 44.08 g/mol.

Given the following data:

Mass = 23.6 gramsVolume = 12.0 LitersStandard temperature = 273 KStandard pressure = 1 atm.

To calculate the molecular mass (molar mass) of this gas, we would use the ideal gas law equation;

[tex]PV=\frac{MRT}{MM}[/tex]

Where;

P is the pressure.V is the volume.M is the mass of substance.MM is the molar mass of a substance.R is the ideal gas constant.T is the temperature.

Making MM the subject of formula, we have:

[tex]MM = \frac{MRT}{PV} \\\\MM = \frac{23.6\times 0.0821 \times 273}{1 \times 12}\\\\MM = \frac{528.95}{12}[/tex]

Molar mass, MM = 44.08 g/mol.

The bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.

The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

1. Calculate the grams of solute contained in 450. mL of a 0.075 M solution of CuCl2.

Answers

Answer:

4.6 grams CuCl2

Explanation:

Since molarity is a representation of moles per liter, we first want to convert 450. mL to liters:

450. mL * 1 L/1000 mL = 0.450 L

Now, we can use this number and the molarity to figure out the answer:

0.075 M means that for every liter, there is 0.075 moles of CuCl2.  Thus, we can multiply the amount of moles per liter by the number of liters of solution.

0.075 moles/1 L * 0.450 L = 0.03375 moles

Then, we need to round this to the appropriate number of significant figures, which gives us:  

0.034 moles CuCl2

Next, we can find the grams of CuCl2.  To do this, we first need to find the molar mass of CuCl2.  The molar mass of Cu is 63.546 g/mol and the molar mass of Cl is 35.453 g/mol, so the molar mass of CuCl2 is as follows:

(1 Cu * 63.546) + (2 Cl * 35.453) = 134.45 g/mol CuCl2

Now, we can multiply the grams per mole by the number of moles of CuCl2 in our solution:

134.45 g/mol * 0.034 moles = 4.5713 grams = 4.6 grams CuCl2, rounded to the appropriate significant figures.
