3 O2 + CS2 = CO2 + 2 SO2
That is the balanced equation!
I may be late lol!!
Hope it helps
<h2>A sample of gold (Au) has a mass of 72.04g. Calculate the number of atoms of gold (Au): It is equal to ==2.207 x 10²³ number of atoms </h2>
Explanation:
we can find number of atoms in a given sample by the formula :
Number of atoms = Given mass /atomic mass x Avogadro's number
or , it can be written as :
Number of atoms = given mass /atomic mass x 6.022 x 10²³
Now in above asked question , the values given are :
Mass of sample of gold = 72.04g
Atomic mass of gold : 196.6
Avogadro's number = 6.023 x 10²³
so, using the above formula we have :
Number of atoms = 72.04 /196.6 x 6.022 x 10²³
= 0.3664 x 6.022 x 10²³
=2.207 x 10²³ number of atoms
Atomic mass is the number of protons and neutrons in an element while an atomic number is the number of protons in the element.
Answer:
The water will absorb 1004.16 Joule of heat
Explanation:
Step 1: Data given
Mass of the metal = 58.00 grams
Temperature of the metal = 100.00 °C
Mass of water = 60.00 grams
Temperature of water = 18.00 °C
Final temperature = 22.00 °C
Specific heat of water = 4.184 J/g°C
Step 2: Calculate the amount of heat absorbed by the water in joules
Q = mass *specific heat *ΔT
⇒ with Q = the heat absorbed by water
⇒ with mass of water = 60.00 grams
⇒ with specific heat of water = 4.184 J/g°C
⇒ with ΔT = The change in temperature of water = T2 - T1 = 22 - 18 = 4.0 °C
Q = 60.00 * 4.184 J/g°C * 4.0 °C
Q = 1004.16 J
The water will absorb 1004.16 Joule of heat
