I need help with this molecular formula problem really quick!!

Answers

Answer 1

Answer:

Answer: From top to bottom, 1 3 4 5 6

Explanation: The empirical formula is the most reduced whole number ratio of elements. N2O4 is the only compound that can be further reduced, making the empirical formula NO2, and thus is different from the molecular formula.

What is the process in which an unstable atomic nucleus emits charged particles or energy or both?a. radioactivity
b. oxidation
c. decomposition
d. none of the above

Answers

Answer:

Option (A)

Explanation:

Radioactivity is defined as a process in which an unstable atomic nucleus decays continuously and after a specific period of time changes into a much more stable element. During this time of decay, the nucleus emits charged particles (energy) which are known as the α, β and γ particles. These are often emitted in the form of electromagnetic energy and are very dangerous to health.

The radioactive elements decay at a certain rate which is commonly known as the half-life. Half-life is basically defined as the time required by a radioactive substance to decay half of its initial composition.

Thus, the correct answer is option (A).

What hypothesis did Miller-Urey test in their experiment?A. Organic molecules can form in a reducing atmosphere.
B. Earth is a primordial soup.
C. Organic molecules cannot survive in a reducing atmosphere.

Answers

The answer s the option B. Earth is a primordial soup. They tested Oparin's theory which states that the life (organic matter) can be formed from inorganic compounds. They placed a mixture of compounds that are supposed to be present in Earth before life started, which are CO2, methane (CH4) and water (H2O), hydrogen (H2) and nitrogen (N2) in a closed vessel and used electric discharges (to simulate the effects of the storms that happened in Earth without atmosphere). Then they analyzed the products obtained and indeed found organic matter. Yet, this does not mean that life is definetly originated in this form.

How many moles of chlorine gas are contained in 9.02×10^23

Answers

1 mole ----------- 6.02x10²³ molecules
? ----------- 9.02x10²³ molecules

9.02x10²³ * 1 / 6.02x10²³

9.02x10²³ / 6.02x10²³

= 1.4983 moles

What triggers the small earthquakes that occur around a volcano before an eruption

Answers

Before the eruption,the fluid pressure from the rising magma (dense liquid) cracks the rocsk, the tectonic plates under the Earth's crust are moved and as a result earthquakes are caused. Manu small earthquakes in the area near a volcano hint what may happen.

If you make an electromagnet using a battery circuit and a steel nail, how can you increase its magnetic strength? A. replace the nail with a copper rod B. wrap more coils of wire around the nail C. use a longer nail D. remove the plastic insulation from the wire coil

Answers

Answer: The correct answer is "wrap more coils of wire around the nail".

Explanation:

Electromagnet: When the current passes through iron core wounded by the coils then it will get magnetized. It is not a permanent magnet.

It will loose its magnetism when the current does not flow in it.

The poles of the electromagnet can be changed. They are not fixed.

In the electromagnet, the strength of the magnetism can be increased or decreased by increasing the number of turns in the coil and by increasing the current.

In the given problem, If you make an electromagnet using a battery circuit and a steel nail, the magnetic strength can be increased by wrapping more coils of wire around the nails.

Therefore, the correct option is (B).

we can increase the strength of an electromagnet by wrapping more coils of wire around the nail.
