Answer:
nitric acid anhydride
OR
Dinitrogen pentaoxide
The name of N4O10 is Tetranitrogen decaoxide.
In order to name this compound, we have to consider the number of atoms of each element in the compound.
Looking at the compound, we can see that there are four nitrogen and ten oxygen atoms. Nitrogen is an element in group 15 of the periodic table and has five valence electrons. Oxygen is an element in group 16 of the periodic table and has six valence electrons. These two elements combine to give tetranitrogen decaoxide (N4O10).
Hence, the accurate name of the compound is tetranitrogen decaoxide.

Answer:
Substance 2
Explanation:
The stronger the intermolecular forces are, the more energy is required, so the higher the melting point is.
Answer:
Substance 2
Explanation:
I know this because substances with a stronger molecular attraction are less susceptible to melting quicker than substances who have a weaker attraction with each particle. Therefore, substance 2, which melted after substance 1, has a stronger molecular attraction then substance 1.

The radioisotope technetium-99 is often used as a radiotracer to detect disorders of the body. It has a half-life of 6.00 hours. If a patient received a 20.0 mg dose of this isotope during a medical procedure, how much would remain 24.0 hours after the dose was given?
Answer:
[tex]0.25\ \text{mg}[/tex]
Explanation:
[tex]t_{1/2}[/tex] = Half-life of technetium-99 = 6 hours
[tex]N_0[/tex] = Initial mass of sample = 20 mg
[tex]t[/tex] = Time elapsed = 24 hours
Amount of mass remaining is given by
[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=20e^{-\dfrac{\ln 2}{6}\times 24}\\\Rightarrow N=0.25\ \text{mg}[/tex]
The amount of the sample that would remain is [tex]0.25\ \text{mg}[/tex].
Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
A
The gases reflect all of the heat from the Sun, preventing it from reaching Earth's surface.
B
The gases absorb all of the heat from Earth's surface, preventing it from radiating into space.
С
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface.
D
The gases reflect some of the heat from Earth's surface, holding it away from the surface in space.
Answer: The answer is c
Explanation:
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of the earth shields its people by absorbing dangerous sun rays and preserving a constant temperature. It protects Earth from many space hazards and enables life there. As a result, it is crucial for regulating climate and a source of life on planet.
The majority of the infrared energy from the Sun is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds, creating the greenhouse effect. This causes the lower atmosphere and the Earth's surface to warm.
Thus, the gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

6. A 3 liter solution contains 140 g of Sodium Bromide (NaBr). What is the molarity of the solution?
Please help I am being timed
The molarity = 0.454 M
Further solutionGiven
Volume = 3 L of solution
mass = 140 g of NaBr
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]
mol of NaBr :
= mass : MW
= 140 g : 102,894 g/mol
= 1.361
Molarity :
= 1.361 mol : 3 L
= 0.454 M

A compound is known to contain 15% sulfur.
What mass of sulfur does this correspond to if there is a total of 200g of the compound containing sulfur?
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
