Each chemical reaction, you may say that there are many possible balanced reactions since the coefficients of the reactants and of the products can be another set of numbers as long as the ratios of the compounds would be the same. The most preferred balanced reaction would be the reaction which have the lowest value of coefficients. Example would be the reaction of HCl and NaOH.
HCl + NaOH = NaCl + H2O (This would be the most preferred one since the coefficients are in the lowest value)
Other equivalents would be:
2HCl + 2NaOH = 2NaCl + 2H2O
3HCl + 3NaOH = 3NaCl + 3H2O
4HCl + 4NaOH = 4NaCl + 4H2O
Answer:Supersaturated
Explanation:The answer is supersaturated because supersaturation is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. It is supersaturated because there is already a sugar solution and adding another sugar is more than the maximum amount of solute.
Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
Answer:
w = 0.00098 N
Explanation:
Given data:
Acceleration = 9.80 m/s²
Mass of honey = 0.0001 Kg
weight = ?
Solution:
Formula:
w = mg
w = weight
m = mass
g = acceleration due to gravity
Now we will put the values in formula:
w = 0.0001 Kg × 9.80 m/s²
w = 0.00098 N
Molar mass of CuSO4*5H2O = <span>63.5 + 32 + 4(16) + 5(18) = 249.5 g/mole
molarity is calculated as follows:
molarity = number of moles of solutes/liters of solution
We will assume that the number of liters = 1
Substituting in the above equation:
0.02 = number of moles of CuSO4*5H2O / 1
number of moles = 0.02 moles
number of moles = mass/molar mass
mass = number of moles * molar mass
mass = 0.02 * </span><span>249.5 = 4.99 grams</span>
