2. Water is an excellent solvent. With water being a polar
ladessa [460]

Answer:

Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.

When 5.467 grams of compound z are burned in excess oxygen, 15.02 grams of co2 and 2.458 grams of h2o are produced. determine it
Vera_Pavlovna [14]

Given the mass of CO2 =15.02 g

Moles of CO_{2}=15.02 gCO_{2} *\frac{1 molCO_{2} }{44.01 gCO_{2} } =0.341 mol CO_{2}

Mass of H2O = 2.458 g

Moles of H_{2}O=2.458 g H_{2}O*\frac{1molH_{2}O }{18.02g H_{2}O } =0.136molH_{2}O

Moles of C = 0.341 mol CO_{2}*\frac{1 molC}{1 molCO_{2} }  =0.341molC

Moles of H = 0.136 mol H_{2}O * \frac{2 mol H}{1 mol H_{2}O } =0.272 mol H

Mass of C in the sample = 0.341 mol C*\frac{12.01g C}{1 mol C} =  4.095 g C

Mass of H = 0.272 mol H *\frac{1.01 g H}{1 molH}=0.275 gH

Mass of O in the sample = 5.467 g - (4.095 g +0.275 g) = 1.097 g O

Moles of O = 1.097 g O * \frac{1 molO}{16 g O} =0.0686 mol O

Simplest mole ratios of the elements in the compound:

Cx_{\frac{0.341mol}{0.0686mol}} H_{\frac{0.272mol}{0.0686mol} }O_{\frac{0.0686mol}{0.0686mol} }

Therefore the empirical formula of the compound is C_{5}H_{4}O

Circle the letter next to each sentence that is true concerning the compressibility of gases. a. The large relative distances be
Anuta_ua [19.1K]

Answer:

The large relative distances between particles in a gas means that there is considerable empty space between the particles.

The assumption that particles in a gas are relatively far apart explains gas compressibility.

Compressibility is a measure of how much the volume of matter decreases under pressure.

Energy is released by a gas when it is compressed

Explanation:

The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.

Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.

A balloon has a pressure of 3.1 atm at a volume of 155 ml. if the temperature is held constant, what is the volume (ml) if the p
GarryVolchara [31]

Answer:

45.8 mL

Explanation:

If all variables are held constant, the new volume can be found using the Boyle's Law equation. The equation looks like this:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You can find the new volume by plugging the given values into the equation and simplifying.

P₁ = 3.1 atm                        P₂ = 10.5 atm

V₁ = 155 mL                       V₂ = ? mL

P₁V₁ = P₂V₂                                                 <----- Boyle's Law equation

(3.1 atm)(155 mL) = (10.5 atm)V₂                <----- Insert values

480.5 = (10.5 atm)V₂                                  <----- Multiply 3.1 and 155

45.8 = V₂                                                    <----- Divide both sides by 10.5
