Answers

The cost of using 14,400 watts hour would be  $43.2.

What is Energy ?

Energy is defined as the capacity to do work.

It is given in the question that

A 1600 watts electric oven is used for 9 hours

Power * Time

power = 1600 watts

Time = 9 hours

Total energy consumed = 1600 watts * 9 hours
= 14,400 watts hour

energy is measured in Kilowatts hour

= 14,440 watts hour

14,440/1000 kwh

= 14.4 kwh

It is given that the cost per unit of energy is $3.00 per kwh

Therefore , the cost of using 14,400 watts hour would be 14.4 * 3

= $43.2

A) 40 B) 44 C) 50 D) 55

Answers

The volume of CO2 prodiced when 12 mL of CH4 and 8 mL of C4H10 is burnt is 56 mL.

What is the equation of the reaction?

The equation of the combustion of C2H6, CH4, C4H10, and C3H8 gases are given below:

2 C2H6 + 7 O2 ---> 4 CO2 + 6 H20

C3H8 + 5 O2 ---> 3 CO2 + 4 H20

CH4 + 2 O2 ----> CO2 + 2 H2O

2 C4H10 + 13 O2 ---> 8 CO2 + 10 H2O

X moles of C2H6 will produce 2X moles of CO2

Y moles of C3H8 will produce 3Y moles of CO2

Thus;

X + Y = 20 mL

X =20 - Y ---(1)

2X + 3Y = 52 mL ---(2)

Solving for X by substituting in (2)

2 (20 - Y) + 3Y = 52

40 - 2Y + 3Y = 52

Y = 12 mL

Then X = 8 mL

Volume of CO2 produced when 12 mL of CH4 and 8 mL of C4H10 is burnt = (12 × 2 + 8 × 4) = 56 mL

Therefore, the volume of CO2 produced is 56 mL.

Balance the following chemical reaction :p(s) + cl2(g) = pcl5(s)

Answers

Answer:

[tex]2\text{P}+ 5\text{Cl}_2 \rightarrow 2\text{PCl}_5[/tex]

Explanation:

Answer:

2P (s) + 5PCl₂ (g) → 2PCl₅ (s)

Explanation:

There are 2 chlorine atoms on the reactant side and 5 chlorine atoms on the product side.

Hence, multiply the left chlorine molecule by 5 and right compound by 2.

⇒ P (s) + 5 × Cl₂ (g) → 2 × PCl₅

⇒ P (s) + 5Cl₂ (g) → 2PCl₅ (s)

But, now we see that there is 1 phosphorus atom on the reactant side and 2 phosphorus atoms on the right.

So, multiply the left phosphorus atom by 2 to balance.

⇒ 2 × P (s) + 5PCl₂ (g) → 2PCl₅ (s)

2P (s) + 5PCl₂ (g) → 2PCl₅ (s)

A client who weighs 70 kg is receiving a solution of 0.9% sodium chloride (normal saline) 500 ml with dopamine 800 mg at 5 ml/hour. how many mcg/kg/minute is the client receiving

Answers

The mcg/kg/minute the client is receiving is 1.904 mcg/kg/min whose weight is 70 kg.

What does mcg kg mean?

1 milligram (mg) = 1000 micrograms (mcg) or 0.001 grams (g) 1 g = 1000 mg 1 kilogram (kg) = 1000 g 1 kg = 2.2 pound (lb) 1 liter (L) = 1000 milliliters (mL)

The number of mcg/kg/minute = flow rate × concentration ÷ mass of client

Flow rate = 12 ml/hour = 12 ml/hour × 1 hr/60 min = 0.2 ml/min

Concentration = mass of dopamine/volume

where

mass of dopamine = 800 mg and

volume =  500 ml

Concentration =800 mg/500 ml

= 1.6 mg/ml

= 1.6 mg/ml × 1000 mcg/mg

= 1600 mcg/ml

mass of client = 70 kg

Calculating mcg/kg/minute

So, substituting the variables into the equation, we have

mcg/kg/minute = flow rate × concentration ÷ mass of client

mcg/kg/minute = 0.08 ml/min × 1600 mcg/ml ÷ 70 kg

mcg/kg/minute = 320 mcg/min ÷ 70 kg

mcg/kg/minute = 1.904 mcg/kg/min

Thus, the mcg/kg/minute the client is receiving is 1.904 mcg/kg/min
