Note: We must keep the units we use consistent. The Cp is given in cal/gC so we will use cal for energy, grams for mass and C for temperature.
1)
Heat supplied can be calculated using:
Q = mCpΔT; where m is the mass, Cp is the specific heat capacity and ΔT is the temperature change.
Q = 367 x 0.092 x (60 - 23)
Q = 125 Cal
2)
Using the same equation:
125 = 60 x 0.092 x (T - 23)
T = 45.6 C
Hey there!
Great question;)
Answer:it is neutrally charged because it has the same number of protons(positively charged iona) and electrons(negatively charged ions)
I hope this helps:)
Answer:
Is the source an authority on the subject?
Explanation:
To figure out which source is accurate, you want to find out the source's authority on the subject. For example, if you wanted to learn how to play the piano, you wouldn't go to a dance teacher, you would go to someone who knows how to play the piano. The person who knows how to play the piano has more authority to teach the piano than a dance teacher.
The theory of inheritance was proposed by Walter Sutton and Theodor Boveri
the chromosome theory is a principal of genetics, known as the chromosome theory of inheritance, The principal is that all chromosomes are carriers of genetic material that pass from one generation to the next.
Answer:
[CH₃COOH] = 1.70 M
Explanation:
When we talk about concentration we can determine Molarity
Molarity determines the moles of solute that are contained in 1L of solution.
In this case our solute is the acetic acid.
M = mol/L
M = 0.99 mol /0.58L → 1.70 M
We can also make a rule of three
In 0.58 L of solution we have 0.99 moles of solute
In 1 L of solution we may have (1 . 0.99) / 0.58 = 1.70 moles
Acetic acid is a weak acid, partially dissociated in water.
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
