The general formula for the alkenes is C nH 2n
<u>Alitta Succinea</u> is the name of the Clam Worm
The mass of the piece of wood is 35.58 g.
Joule = M × T × C
Where, M = mass
T = change in temperature(42C-23C=19 C)
C = specific heat capacity = 1.716 joules/gram
Substituting the values in the equation,
1160 = M × 19 × 1.716
M = 1160/32.604 = 35.58 g
Therefore, the mass of the piece of wood = 35.58 g
<h3>What is meant by specific heat capacity?</h3>
A material's specific heat capacity, which is defined as its heat capacity divided by its mass, determines how much energy is required to increase a gram's temperature by one degree Celsius (or one Kelvin)
<h3>What is mass?</h3>
Mass is the quantity of matter in a physical body.

<u>Answer:</u>
17%
<u>Explanation:</u>
Mass of a piece of copper calculated by student = 8.3 grams
Actual mass of copper = 10 grams
We know the formula for the percent error:
Percentage error = (| experimental value - actual value | / actual value) * 100
So substituting the given values in the above formula:
Percent error = (|8.3 - 10| / 10) * 100 = (1.7/10) * 100 = 17%
Answer:
1.041g is the maximum sigle dose for the person
Explanation:
The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults
To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):
153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>
<em />
As the maximum dose is 15.0mg / kg, the dose of the person is:
69.4kg * (15.0mg acetaminophen / kg) =
<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>
