<span>One reason confidentiality would be important at a time of a medical emergency is if the patient didn't want people to know about the emergency so that they wouldn't worry. Another reason is for instance if that medical emergency was something that the patient considered embarrassing then they wouldn't want people to know.</span>

Anvisha [2.4K]

Answer:

Explanation:

This experiment converts mechanical energy to electrical energy. The movement of the magnet in and out of the coil is mechanical energy and the current induced in the circuit as a result of the magnet movement is electrical energy.

It should be noted that generally electromagnetic induction as described by faraday (and indeed the experiment described in the question) involves the transformation of mechanical energy into electrical energy. It's application is used in transformers, electric motors and generators.

Butyl butyrate is an ester that is a naturally occurring oil used in the flavor industry for its fruity scent. If the steam dist
Snezhnost [94]

Answer:

The correct answer is 62.5 %.

Explanation:

Based on the given information, the partial pressure of butyl butyrate is 50 mmHg and the partial pressure of water is 710 mmHg.  

Hence, the total pressure is 710+50 = 760 mmHg

According to Dalton's law of partial pressure,  

Partial pressure = mole fraction * total pressure

Mole fraction of water is,  

Partial pressure of water/Total pressure = 710/760 = 0.93

Similarly, the mole fraction of butyl butyrate is,  

Partial pressure of butyl-butyrate/Total pressure = 50/760 = 0.07

Therefore, mole% of water is 0.93 * 100 = 93 %

For calculating mass%,  

Mass of H2O = 0.93 * 18 = 16.8 grams (The molecular mass of water is 18 grams per mole)

The molecular mass of butyl-butyrate is 144 gram per mole

The mass of butyl-butyrate = 144 * 0.07 = 10.08 grams

The mass percent of water will be,  

Mass % of water/Total mass % * 100 = 16.8 / 10.08 + 16.8 * 100 = 62.5%.

If 42.389 g of Fe3Br2 is dissolved in enough water to give a total volume of 750 mL, what is the molarity of the solution
TEA [102]

Answer:

M=0.173M

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of solute divided by the volume of the solution in liters and has units of mol/L or M:

M=\frac{n}{V}

For the solute, Fe3Br2, which has a molar mass of 327.3430 g/mol, the moles in 42.389 g are:

n=42.389g*\frac{1mol}{327.3430g} =0.12949mol

Thus, since the volume in liters is 0.750 L from those given 750 mL, the molarity turns out:

M=\frac{0.12949mol}{0.750L}\\\\M=0.173M

Best regards!

Normal saline is 0.920% (w/v) NaCl in water. How many grams of NaCl are needed to prepare 15.0 L of normal saline? Normal saline
Rama09 [41]

Answer:

To prepare a 15L 0.920 % NaCl solution we need 138 grams of NaCL

Explanation:

Step 1: Data given

Normal saline is 0.920% (w/v)

⇒ 0.92 g NaCl / 100 mL H2O

Step 2: Calculate grams of NaCl needed to prepare 15 L

We need 0.92 grams of NaCl for 100 mL

We need 9.2 grams of NaCL for 1L

For 15L we need 9.2 grams * 15 = 138 grams of NaCl

To prepare a 15L 0.920 % NaCl solution we need 138 grams of NaCL
