Answer: (D) Are there solvents mixed in (or is it water based)?
Elements in the same group have the same amount of electrons.
Elements in the same period have the same amount of atomic orbits.

To solve this problem, all we have to do it to make use of
the principle of ratio and proportion. We are given the following ratio:
1 part Chlorine / 10 parts Water
Now to determine the amount of chlorine needed for 15
ounces of water, all we have to do is to use proportion. Let us say that the
amount of Chlorine needed is x, therefore:
1 part Chlorine / 10 parts Water = x / 15 ounces Water
so,
1 / 10 = x / 15
Therefore calculating for x:
x = 15 / 10
<span>x = 1.5 ounces of Chlorine</span>
Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

Answer:
45830.4 moles
Explanation:
Ideal gas law is the hypothetical equation in which the pressure, volume, and temperature of the gas are directly related. It can be denoted as:
PV = nRT
The ideal gas law is:
PV = nRT
where,
P = Pressure
V = Volume
R = Gas constant
T =Temperature
n = moles
Given:
Moles in container = 1.95
Temperture = 294.85 K
Pressure = 3.75 atm
Volume =?
Substituting the values:
V = nRT/P
V = 1.95 × 0.082 × 294 / 3.75
Volume = 12.5 L
Now, the condition when changed, such that temperature is 301.25 K, pressure is 0.998 atm, and Volume is 12.5 L, then moles will be equal to:
PV/RT = n
0.998 × 12.5 / 0.082 × 301.25 = n
n = 45830.4 moles
Therefore, 0.521 moles is still present in the container.
