Answer:

Lavoisier disproved the phlogiston theory. He demonstrated that there was an element called oxygen that played a major role in combustion. He also showed that the mass of products in a reaction are equal to the mass of the reactants. The phlogiston theory did not account for the weight changes found in fire. Lavoisier hypothesized that it was probably the fixation and release of air, rather than fire, that caused the observed gains and losses in weight.

Explain what is meant by the term "excited state" as it applies to an electron. Is an electron in an excited state higher or low
nikdorinn [45]

Answer:

Excited state of an electron is the state attained by an electron after it has absorbed energy and it moves further from the nucleus.

an electron is at higher energy when excited and at lower energy when at ground state.

an excited electron is less stable due to the decrease in the nuclear force of attraction and the grounded electron is more stable due to it's close distance to the nucleus.

What is the mass of a baby in grams if the babies weight in 6 pound. 6 oz
MatroZZZ [7]

2721.55422g

Explanation:

First, step is to find out how much is 1pound in grams.

So,

1 POUND x (1 KG/2.204 POUND) x (1000G/1 KG)  which is equal to 453.59g

Here, we got that 1 pound is equal to 453.59g.

In the question, it is given that the weight of the baby is 6 pound.

To convert 6 pounds into grams, we need to multiply 6 pounds with 453.59 g,

6pounds x 453.59g = 2721.55422 g

Hence, the weight of the 6-pound baby in grams will be 2721.55422 grams.
