90 minutes is 1.5 hours.
5 kW * 1.5 hours = 7.5 kWh
8c/kWh * 7.5 kWh = 60 cents
Answer:
Al+3
Explanation:
Ion is a positively or negatively charged species. A neutral species does not carry any charge.
here only Al has +3 charge. So it is an ion.
Answer:
1. 0.138g of valium would be lethel in the woman
2. 125mg/min is the drip of the patient
Explanation:
1. In a body, an amount of Valium > 1.52mg / kg of body weight would be lethal.
A person that weighs 200lb requires:
200<u>lb</u> × (453.6<u>g</u> / <u>1lb</u>) × (1kg / 1000<u>g</u>) = <em>90.72kg (Weight of the woman in kg)</em>
90.72kg × (1.52mg / kg) =
137.9mg ≡
<h3>0.138g of valium would be lethel in the woman</h3>
2. The IV contains 1.5g = 1500mg/mL.
If the patient is receiving 5.0mL/h, its rate in mg/h is:
5.0<u>mL</u>/h × (1500mg/<u>mL</u>) = 7500mg/h
Now as 1h = 60min:
7500mg/<u>h</u> × (1<u>h</u> / 60min) =
<h3>125mg/min is the drip of the patient</h3>
Answer:
See explanation
Explanation:
The overall charge on ClO3− is shown on the image attached to this answer. If we calculate the formal charges on each atom in the structure, we will notice that one oxygen atom has a formal charge of -1 while all other atoms have a formal charge of zero.
This gives the compound an overall charge of -1 as shown in the image attached to this answer. This is the correct Lewis structure for the compound ClO3− .
