The appropriate mixing ratio for a solution to kill blood borne pathogens is 1 part chlorine to 10 parts water if you are mixing
jarptica [38.1K]

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.

A glass container was initially charged with 1.95 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as
rjkz [21]

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.
