1. A cat and it’s litter can’t be related without the producer which in this case is the mother

2. The stripes shows that the two are related and yeah you can have to cats that have the same stripes but that’s not likely, every-time any two cats with stripes are put together the cats show similarities but that doesn’t tell us that their related. Every cat has similar stripes but there is something that’s always gonna be off with the stripes whether the stripes have the same color or the stripes have the same arrangement on the cat. Like people cats have similar traits but that doesn’t mean there related (ex: two blue eyed people, that’s doesn’t prove that their related in any type of way).

Explanation:

Answer:

Inherited characteristics that show that a cat and kitten are related include physical traits such as fur pattern and color, eye shape, and body type. Another example is behavioral traits such as playfulness and social behavior. These traits are passed down from parent to offspring through genes and provide evidence of a familial relationship.

Answer:

The hydroxide [OH-] concentration of the solution is 1.26*10⁻⁵ M.

Explanation:

The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution.

POH indicates the concentration of hydroxyl ions [OH-] present in a solution and is defined as the negative logarithm of the activity of hydroxide ions (that is, the concentration of OH- ions):

pOH= -log [OH-]

A solution has a pOH of 4.90. Replacing in the definition of pOH:

4.90= -log [OH-]

Solving:

-4.90= log [OH-]

1.26*10⁻⁵ M= [OH-]

The hydroxide [OH-] concentration of the solution is 1.26*10⁻⁵ M.

The value of ΔH for the reaction CO(g) + H₂(g) + O₂(g) → CO₂(g) + H₂O(g) is -1272 kJ.

To calculate the enthalpy change (ΔH) for the given reaction, we can use Hess's law, which states that the overall enthalpy change of a reaction is equal to the sum of the enthalpy changes of the individual reactions involved.

Given the enthalpy changes:

1. 2 C(s) + O₂(g) → 2 CO(g)... ∆H = -222 kJ

2. C(s) + O₂(g) → CO₂(g)... ∆H = -394 kJ

3. 2 H₂(g) + O₂(g) → 2 H₂O(g)... ∆H = -484 kJ

We need to manipulate these reactions to obtain the desired reaction:

1. Reverse reaction 2: CO₂(g) → C(s) + O₂(g)... ∆H = +394 kJ

2. Multiply reaction 2 by 2 to balance carbon atoms: 2 CO₂(g) → 2 C(s) + 2 O₂(g)... ∆H = -788 kJ

3. Leave reaction 3 unchanged: 2 H₂(g) + O₂(g) → 2 H₂O(g)... ∆H = -484 kJ

By adding reactions 2 and 3, we obtain the desired reaction:

CO(g) + H₂(g) + O₂(g) → CO₂(g) + H₂O(g)... ∆H = -788 kJ + (-484 kJ) = -1272 kJ

Therefore, the value of ΔH for the given reaction is -1272 kJ.

If 3.25 mol of argon gas takes up 100 l at a specific temperature and pressure, how much space does 14.15 mol of argon occupy under the same circumstances

The most prevalent gas in the atmosphere after nitrogen and oxygen is argon. Argon is a noble gas, making it fully inert, like helium. It is a colourless, odourless gas that has no effect on other substances at all. Despite being a gas, argon has the ability to combine with other substances in specific situations.

The hotness of matter or radiation is expressed by the physical quantity known as temperature. There are three different types of temperature scales: those that are determined using the average translational kinetic energy per freely moving molecule, like the SI scale;

1) V1/n1 = V2/n2

100/3.25 = V2/14.15

V2 = 435.4 L

None of the given options are correct. This calculation suggests that the molecular weight of the gas is much larger than the options provided. It is possible that there was an error in the measurement of the density or the problem was intended to be more complex.

To calculate the molecular weight of a gas with a given density at STP, we need to use the Ideal Gas Law equation PV=nRT and rearrange it to solve for the molecular weight. At STP, the pressure (P) is 1 atm and the temperature (T) is 273.15 K.
First, we need to find the molar volume of the gas at STP, which is 22.4 L/mol. Then, we can use the density (d) and the molar volume (V) to calculate the number of moles (n) using the formula n = d/V.
n = 1.524 g/L / 22.4 L/mol = 0.068 mol
Next, we can use the formula n = m/M, where m is the mass of the gas and M is the molecular weight we want to find. Since we know the density and the molar volume, we can find the mass of the gas using the formula m = dV.
m = 1.524 g/L x 22.4 L/mol = 34.13 g/mol
Now we can plug in the values for n and m in the formula n = m/M and solve for M.
0.068 mol = 34.13 g/mol / M
M = 34.13 g/mol / 0.068 mol = 501.9 g/mol

Explanation:

The length of the iron wire is 2077 cm.

We have to note that the length of the wire is the thing that we are supposed to obtain in this question. We must note that the density of the object is the ratio of the mass to the volume of the object.

In this case, we need to first find the area of the iron wire from;

A = πr^2

A = A rea of the circle

r = radius of the circle

A = 3.142 * (0.2 * 10^-1)^2

A = 1.3 * 10^-3 cm^2

Now;

Density = mass/volume

Volume = Mass/ Density

Volume = 21 g/7.87 g/cm³

= 2.7 cm^3

Then volume = Area * length

Length = Volume/Area

Length = 2.7 cm^3/ 1.3 * 10^-3

Cosmic background radiation is Leftover radiation from the big bang.

What is Cosmic radiation?
When primary photons and particles from outside of the solar system interact with elements of the earth's atmosphere, cosmic radiation, an ionising radiation, is created. The sun's discharge of charged particles, also known as solar flares or "sun storms," is a secondary source of cosmic radiation. The environment in which we live naturally contains ionising radiation, which can be found in the soil, structures, food we eat, and even the bones in our bodies.

Nonionizing radiation, which also includes UV light, radio waves, as well as microwaves, is the other type. Natural radiation has been present in the environment where humans, animals, as well as plants have all evolved, and, with very few exceptions, it poses little danger to human health.

The amount of heat released in a planet's interior by radioactive decay changes with time by gradually decreasing over time.

When a planet forms, the heat generated by the process of accretion causes it to become molten, and the heat from radioactive decay within the planet contributes to keeping it hot.

However, over time, the amount of radioactive isotopes in the planet's interior decreases as they decay, leading to a gradual decrease in the amount of heat released.

This process continues until the planet's interior cools to a point where the heat generated by radioactive decay is no longer significant enough to maintain its molten state. At this point, the planet becomes geologically inactive and its interior cools down to a solid state.

The rate of cooling depends on the size and composition of the planet, as well as the amount and type of radioactive isotopes present.

The atmospheric pressure at the mountaintop is approximately 294 mmHg.

To find the atmospheric pressure at the mountaintop, you'll need to use the relationship between boiling point and atmospheric pressure. The key point to remember is that as altitude increases, atmospheric pressure decreases, which leads to a lower boiling point for water.

In this case, the boiling point of water at the mountaintop is 83°C. You can use the Clausius-Clapeyron equation to find the atmospheric pressure, but it requires some complex calculations. Instead, you can use a simplified approximation that works well for small temperature differences: for every 1°C decrease in boiling point, the pressure decreases by approximately 27.4 mmHg (or 27.4 Torr).

First, find the difference in boiling point compared to sea level:
100°C (normal boiling point) - 83°C (mountaintop boiling point) = 17°C

Next, multiply this difference by 27.4 mmHg/°C to find the change in pressure:
17°C * 27.4 mmHg/°C ≈ 466 mmHg

Now, subtract this change in pressure from the sea-level atmospheric pressure (760 mmHg):
760 mmHg - 466 mmHg ≈ 294 mmHg
