Answer:

Is it true that you shouldn't wash your hair, drink cold water, eat ice cream, or exercise during your period? Please explain your answer.

No, this is not accurate; doing any of these activities is perfectly fine. None of them affects us because they are not connected to our bodily systems. Also, I apologize for any language errors as I utilized Google Translate.

I hope this is helpful :)

Answer:

Explanation:

AgNO3 + NaCl --> AgCl + NaNO3

Moles

of AgNO3

= molarity * volume

= 1 * 0.01

= 0.01 mol

for NaCl

= 0.01 * 1

= 0.01 mol.

According to stoichiometry, one mole of silver nitrate corresponds to one mole of NaCl reacted. Hence,

Moles of AgCl generated = 0.01 × 1

= 0.01 mol AgCl produced.

Heat gained by the solution as precipitation occurs:

Solution mass = density × volume

= 1 × 20

= 20 g.

Using q = m * Cp * (T2 - T1)

= 20 * 4.18 * (32.6 - 25.0)

= 635 J

The absorbed heat of 635 J indicates the reaction released -635 J

Thus, Delta H = -635 J/0.01 mol

= -63500 J/mol

= -63.5 kJ/mol.

Answer: The empirical formula and molecular formula for the analyzed organic compound are and

Explanation:

The combustion chemical equation for a hydrocarbon containing carbon, hydrogen, and oxygen is:

where 'x', 'y', and 'z' represent the subscripts for Carbon, Hydrogen, and Oxygen.

We have the following data:

Mass of

Mass of

We know that:

Molar mass of carbon dioxide = 44 g/mol

Molar mass of water = 18 g/mol

For carbon mass calculation:

12 grams of carbon are found in 44 grams of carbon dioxide.

Thus, in 39.01 grams of carbon dioxide, grams of carbon will be present.

For hydrogen mass calculation:

In 18 grams of water, 2 grams of hydrogen are contained.

Therefore, in 10.65 grams of water, grams of hydrogen will be present.

The oxygen mass in the compound = (13.42) - (10.64 + 1.18) = 1.6 grams.

To derive the empirical formula, you need to perform a few steps:

• Step 1: Convert the provided masses into moles.

Moles of Carbon =

Moles of Hydrogen =

Moles of Oxygen =

• Step 2: Determine the mole ratio of the elements.

Each mole value is divided by the smallest mole value, which is 0.1 moles, to find the mole ratio.

For Carbon =

For Hydrogen =

For Oxygen =

• Step 3: Use the mole ratio values as subscripts.

The ratio of C: H: O = 9: 12: 1

The empirical formula for the compound is

To find the molecular formula, it’s necessary to ascertain the valency, which is then multiplied by each elemental subscript of the empirical formula.

The formula used to calculate the valency is:

Given:

Mass of the molecular formula = 272.38 g/mol

Mass of the empirical formula = 136 g/mol

Substituting values into the equation gives:

Multiplying the determined valency with the empirical formula’s element subscripts results in:

Therefore, the forms of the organic compound are and

To light a Bunsen burner, you should follow these essential steps: First, tidy up the surrounding area and remove any combustible items. Second, shut off the air supply. Third, activate the gas flow to the burner. Fourth, ignite the flame using a lighter. Finally, modify the air intake to regulate the size of the flame.
