Answer:

In seismology, the epicenter refers to the point on the surface of the Earth directly above the focus or a hypocenter, that is, the point where an underground explosion or an earthquake originates. In the given case, the recording station has demonstrated that the epicenter of the recent earthquake was 250 kilometers away, this shows that epicenter was situated somewhere on a circle centered at the recording station within a radius of 250 kilometers.

How many moles of nitrogen, N, are in 61.0 g of nitrous oxide, N2O?
Oksana_A [137]

Answer:

2.77 mol N

Explanation:

M(N2O) = 2*14 + 16 = 44 g/mol

61.0 g * 1 mol/44g = (61/44) mol N2O

                       N2O ---- 2N

                    1 mol         2 mol

            (61/44) mol        x mol

x = (61/44)*2/1 = 2.77 mol N

An object has a mass of 5.52 g and a volume of 12 mL. What is the density of the object?
Rudik [331]

Answer:

<h2>Density = 0.46 g/mL</h2>

Explanation:

Density of a substance can be found by using the formula

<h3>Density =  \frac{mass}{volume}</h3>

From the question

mass = 5.52 g

volume = 12 mL

Substitute the values into the above formula and solve for the Density

That's

<h3>Density =  \frac{5.52}{12}</h3>

We have the final answer as

<h3>Density = 0.46 g/mL</h3>

Hope this helps you

The chemistry of living things and living systems created a new combined field in science known as
Anastasy [175]

Answer:

Biochemistry.

Explanation:

Biochemistry can be defined as the branch of science that deals with the study of the chemical processes, physio-chemical reactions and various substances that are found in living organisms such as animals, plants, and microorganisms.

Simply stated, biochemistry is a field in science that combines both the elements of biology and chemistry in order to study living organisms.

For example, all living organisms have the ability to engage in respiration in other to breathe in oxygen to stay alive. Thus, biochemistry helps us to understand respiration as a physio-chemical process that converts glucose into a form of energy (Adenosine Triphosphate-ATP) that is beneficial to all living organisms.

Hence, the chemistry of living things and living systems created a new combined field in science known as biochemistry.
