Describe the events that occur as water molecules start in hot bath water and end up on the surface of the bathroom mirror.

The correct answer is 13 billion years ago.  

The Big Bang theory is the existing cosmological model for the apparent universe from the most primitive known periods via its consequent large scale evolution. The model illustrates that how the expansion of the universe took place from a very high temperature and high-density state and provides a complete illustration for a wide array of processes comprising the existence of cosmic microwave background, light elements, Hubble's law, and large scale structure.  

The complete measurements of the rate of expansion of the universe put the Big Bang at approximately 13.8 billion years ago, that is, thus regarded as the age of the universe.  

Answer: The moles of product present in the vessel is 0.092 moles

Explanation:

For the given chemical equation:

We are given:

Initial moles of reactant = 0.200 moles

Unreacted moles of reactant = 0.108 moles

Reacted moles of reactant = 0.200 - 0.108 = 0.092 moles

By Stoichiometry of the reaction:

1 mole of reactant produces 1 mole of product

So, 0.092 moles of reactant will produce = of product

Hence, the moles of product present in the vessel is 0.092 moles

Answer:

The correct answer is A.

Explanation:

The periodic table published by Mendeleev in 1869 was the first periodic table to group the elements. Based on the hypothesis that the properties of the elements are a periodic function of their atomic weights, he placed in the table all the elements known up to that moment, which became 63 elements, ordering them in such a way that the elements belonging to the same family appear in the same vertical line. The elements were arranged in the increasing order of their atomic masses.

Have a nice day!

Answer:

14.71 g/cm³

Explanation:

The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water

volume = 36.5 - 31.4 = 5.1 mL

But

1 mL = 1 cm³

5.1 mL = 5.1 cm³

From the question we have

We have the final answer as

14.71 g/cm³
