Water is made up of which two elements?

A client who had a cesarean birth of twins 6 hours ago reports shortness of breath and pain in the right calf. What complication

vova2212 [387]

The complication should the nurse expect is d) pulmonary emboli.

<h3>Why would she develop pulmonary emboli.?</h3>

The danger that can come up as per postpartum is calf pain with dorsiflexion of the foot and this is usually an indication about deep vein thrombosis.

Hence, having shortness of breath can be linked to pulmonary emboli, since, she had a cesarean birth of twins 6 hours ago .

CHECK THE COMPLETE QUESTION BELOW:

a) fluid volume overload

b) infection

c) hemorrhage

d) pulmonay emboli

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

Which of the following best describes why ddt is classified as a persistent organic pollutant.

Ostrovityanka [42]

The reasons why DDT is classified as a persistent organic pollutant are;

DDT can be used to control diseases, such as malaria and typhus, that are spread by insects.

DDT is detected in food worldwide and the general human population is most commonly exposed to the toxin through food.

Persistent Organic Pollutants can be regarded as toxic substances which are made up of organic chemical compounds.

These are industrial chemicals such as;

PCBs

pesticides like DDT.

DDT is classified as a persistent organic pollutant because of it's usefulness in control diseases and it is been found in food stuff across the globe.

How many grams of sucrose, c12h22o11, must be added to 500. G of water at 100°c to change the vapor pressure to 752 mm hg?.

denpristay [2]

The mass number of sucrose that must be added to 500 g of water is 100.979 grams

To be able to solve this question, we need to use the number of moles concept and mole fraction concept.

<h3>What is the number of moles?</h3>

The number of moles is related to the mass of the substance divided by the molar mass of the substance.

From the given parameters;

The number of moles of water = mass/molar mass

Mass of water = 500 g
the molar mass of water = 18.02 g/mol

number of moles = 500 g/ 18.02 g/mol

number of moles = 27.75 moles

However,

the standard vapor pressure of the solvent $\mathbf{P^0_{water}}$ = 760 mmHg

the vapor pressure of the solute = 752 mmHg

Using the mole concept:

$\mathbf {X_{C_{12}H_{22}O_{11}} = \dfrac{n_{C_{12}H_{22}O_{11}}}{n_{H_2O}+n_{C_{12}H_{22}O_{11}}} }$

By relative lowering of vapor pressure:

$\mathbf{\dfrac{P^0_{H_2O} - P_{H_2O}}{P^0_{H_2O}} = X_{C_{12}H_{22}O_{11}}}$

$\mathbf{\dfrac{760 -752}{760} = \dfrac{n_{C_{12}H_{22}O_{11}}}{27.75 +n_{C_{12}H_{22}O_{11}}} }}$

$\mathbf{0.01053 = \dfrac{n_{C_{12}H_{22}O_{11}}}{27.75 +n_{C_{12}H_{22}O_{11}}} }}$

$\\ \\ \mathbf{0.01053 (27.75) +0.01053 (n_{C_{12}H_{22}O_{11}} ) = n_{C_{12}H_{22}O_{11}}}$

$\\ \\ \mathbf{0.2922075 =0.98947
 (n_{C_{12}H_{22}O_{11}} )}$

$\\ \\ \mathbf{ (n_{C_{12}H_{22}O_{11}} ) = \dfrac{0.2922075 }{0.98947}}$

$\\ \\ \mathbf{ (n_{C_{12}H_{22}O_{11}} ) =0.295 \ moles}$

The mass of sucrose = number of moles × molar mass

The mass of sucrose = 0.295 moles × 342.3 g/mol

The mass of sucrose = 100.979 grams
