The basic building blocks are atoms
Answer:
The answer is True
Explanation:
This is because they are equivalent and have same number of bit.
Answer:
0.733 J/g °C
Explanation:
<u>Step 1 : Write formule of specific heat</u>
<u />
Q
=
mc
Δ
T
with Q = heat transfer (J)
with m = mass of the substance
with c = specific heat ⇒ depends on material and phase ( J/g °C)
Δ
T = Change in temperature
<u />
in this case :
Q = 38.5 J
<u>m = 17.5g</u>
<u>c= has to be determined</u>
<u>Δ
T = 3 (°C)</u>
<u />
<u>Step 2: Calculating specific heat</u>
⇒ via the formule Q
=
mc
Δ
T
38.5 J = 17.5g * c * 3
38.5 = 52.5 *c
c = 38.5 / 52.5
c = 0.733 J/g °C ⇒ 0.733 is reported to three significant digits due to the precision.
The specific heat of this metal is 0.733 J/g °C
The molarity of acetic acid is calculated as follows
find the number of moles of NaOH = molarity x volume
= 17x0.2 = 3.4 moles
write the equation for reaction
CH3COOH + NaOH = CH3COONa +H2O
since ratio is be of CH3COOH to NaOH is 1:1 the moles of CH3COOH is therefore = 3.4 moles
therefore the molarity = moles/volume
= 3.4 /10 = 0.34 M
I need to know this too. Hopefully someone answers quick lol
