HELP ME WITH THIS QUESTION ASAP PLESE!!

Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Answer:

[tex]CCl_{2}[/tex]

Explanation:

When calculating an empirical formula from percentages, assume you have a 100g sample. This allows you to convert the percentages directly to grams, because X % of 100g is X grams.

So:

14.6% C = 14.6g C, 85.4%Cl = 85.4g Cl

The next step is to divide each mass by their molar mass to convert your grams to moles.

14.6g/12.01 = 1.22 mol

85.4g/35.45= 2.41 mol

Then you will divide all of your mol values by the SMALLEST number of moles. This gives you whole numbers that are the mole ratio (subscripts) of the empirical formula.

1.22 mol/1.22 mol = 1

2.41 mol/1.22 mol = 2

So the empirical formula is

[tex]CCl_{2}[/tex]

The empirical formula of the compound is CCl2.

HOW IS EMPIRICAL FORMULA CALCULATED:

C = 14.6g ÷ 12g/mol = 1.22mol

Cl = 85.4g ÷ 35.5g/mol = 2.41mol

C = 1.22mol ÷ 1.22 = 1

Cl = 2.41mol ÷ 1.22 = 1.97

Approximately, the carbon to chlorine ratio is 1:2, hence, the empirical formula of the compound is CCl2.

Answer:

A sample of helium gas has a volume of 620mL at a temperature of 500 K. If we ... to 100 K while keeping the pressure constant, what will the new volume be?

Explanation:

A sample of helium gas has a volume of 620. Ml at a temp of 500 K. If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.

The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

According to Charles' Law, at constant pressure,

V1 / T1 = V2 / T2

V1 = 620 ml and T1 = 500K, V2 = ? , T2 = 100K

620 ml / 500K = V2 / 100K

V2 = ( 620 ml ) ( 100K ) / 500K

Volume = 124 ml

Thus, If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.

Answer:

23 g sodium

Explanation:

In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).

According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23

Using the formula; mole = mass/molar mass

- Sodium = 23g/23g/mol = 1mol

- Krypton = 42g/84g/mol = 0.5mol

- Carbon = 24g/12g/mol = 2mol

- Pottasium = 78g/39g/mol = 2mol

Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

Answer:

6.25 x 10^-4 moles H2O

Explanation:

moles H2O = 10 x 10^-3 g O2 x (1 mol O2/MM O2) x (2 moles H2O/ 1 mol O2) =

= (10^-2 / 32) x 2 = 6.25 x 10^-4 moles H2O

conversion factor 2moles H2O = 1 mol O2

MM O2 = 32g/mol

mass O2 = 10 mg = 10 x 10^-3 g

This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Answer:

make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.

Explanation:

A chemical reaction can be balanced by multiplying each side with suitable integers such  that the number of each element in the reaction must be equal number on both side.

According to the law of conservation of mass for  a chemical reaction, the total mass in the reactant side is equal to the total mass in the product side. Thus, a balanced chemical equation represents the perfect stoichiometry for each reactants and products.

The number of each elements in both side have to be equal in number. If they are unequal on both side, we can balance the reaction by multiplying with suitable integers.

Lets have one example. Consider the given reaction.

[tex]\rm CH_{4} + O_{2} \rightarrow H_{2}O + CO_{2}[/tex]

Here, 4 H are in left side and only 2 in right side. Similarly number of oxygen also not balanced.

The balanced equation requires a coefficient of 2 for water and 2 for oxygen in reactant thus, it can be written as:

[tex]\rm CH_{4} + 2O_{2} \rightarrow 2H_{2}O + CO_{2}[/tex]

0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.

According to Ideal Gas Equation,

PV = nRT

Therefore, P ∝ T

P₁T₂ = P₂T₁

Given :

P₁ = ?

P₂ = 1.11 atm

T₁ = 30.0 C

T₂ = 15 C

Solving :

P₁ x 30 = 1.11 x 15

P₂ = 0.555 atm

Hence, 0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.
