Answer:
212 degrees F, and 100 degrees C.
Explanation:
If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212 F, the water will boil. That means that it wont just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself. :)
Answer: 2 C2H4 + 6 O2 => 4 CO2 + 4 H2O
Explanation:The coefficient are as follows: 2: 6: 4: 4
Each atom on the reactant and product side are equal.
Reactant Product
C 2x2 = 4 4x1 = 4
H 2x4 = 8 4x2 = 8
O 6x2 = 12 (4x2) + 4 = 12
Answer:
Carbon 12 and carbon 13
Carbon isotope 12 exist as 98.9%
Explanation:
Answer:
2.675 moles of Chlorine gas are required
Explanation:
Chlorine gas, Cl2, reacts with NaBr to produce NaCl and Br2 as follows:
Cl2 + 2NaBr → 2NaCl + Br2
<em>Where 1 mole of chlorine gas produce 2 moles of NaCl</em>
<em />
Thus, to produce 5.35 moles of NaCl are required:
5.35mol NaCl * (1mol Cl2 / 2mol NaCl) =
<h3>2.675 moles of Chlorine gas are required</h3>
Answer:
The volume for a piece of gold that has the mass of 318,67 g is 16,50cm3
Explanation:
Density = mass / volume
Volume = mass/ density
Volume = 318,97 g / 19,32 g/cm3 = 16,50cm3
