8 0

Answer:

1. a)

2. a)

3. b)

4. d)

Explanation:

The disposal method is how we throw away the wastes. In a chemical lab, the correct disposal method guarantees the security of the environment and the humans and animals that may be in contact with the materials.

So:

1. Excess chemical: Because it can be toxic, it may be disposed of in the appropriate waste container, which will depend on the characteristics of the material;

2. Reaction mixture: As the excess chemical, it can be toxic, so it must be disposed of at an appropriate waste container;

3. Used filter paper: Generally, the solids in the filter paper is not toxic, so it can be thrown away in the trash can;

4. Cracked or chipped beaker: Because the beaker is made of glass, it can cut when broken, so it must go to a broken glass box, that will protect the people that will deal with it.

The maximum efficiency possible in an energy conversion process that is not limited by the second law of thermodynamics
Anna [14]

Answer:

100 %

Explanation:

The maximun efficiency possible (whem not limited by the  second law of thermodynamics) happens when all the energy used is transformed into the type of energy we required with no other transformations.

For example, in an engine we want that all the energy we supply is being converted to work. That's the ideal case, but in reality always some of that energy is lost in the form of heat.

If the density of a liquid 102g/cm^3, how many milligrams will be in 63 mL of that liquid?
Ede4ka [16]

Answer:

<h2>6426000 mg</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

63 mL = 63 cm³

We have

mass = 102 × 63 = 6426

But 1 g = 1000 mg

6426 g = 6426000 mg

We have the final answer as

<h3>6,426,000 mg</h3>
