<u>Answer:</u> The total pressure of the container is 140.2416 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the total pressure, we use the law given by Dalton, which is:
We are given:
Vapor pressure of hydrogen gas, 
= 78 kPa
Vapor pressure of oxygen gas, 
= 2.4416 kPa
Vapor pressure of nitrogen gas, 
= 59.8 kPa
Putting values in above equation, we get:
Hence, the total pressure of the container is 140.2416 kPa
Answer:
In many plants species , a plant have different patterns on their leaves. It is because of mutations which occurs due to change in the DNA or genetic makeup because of environmental factors such as UV light and other substances.
Explanation:
Mutation refers to the sudden change which occurs in the genetic makeup of the cell due to the exposure to harmful radiations such as UV radiation and gamma radiation. In Plant cells, mutation also occurs due to the external environment. Sometimes it occurs naturally and sometimes due to certain radiation or smoke.
Answer:
Explanation:
Hello!
In this case, since the energy involved during a heating process is shown below:
Whereas the specific heat of water is 4.184 J/(g°C), we can compute the heated mass of water by the addition of 11.9 kJ (11900 J) of heat as shown below:
Thus, by plugging in, we obtain:
Best regards!
The ways in which ammonia can be identified is mentioned in below pointers.
<h3>What is Ammonia ?</h3>
Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
A stable binary hydride, and the simplest pnictogen hydride.
Ammonia is a colourless gas with a distinct pungent smell.
Biologically, it is a common nitrogenous waste,
Three ways in which ammonia gas can be identified is:
- It has a sharp characteristic odor.
- When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.
- It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

The visible constellations<span> are definitely different
between the Northern and Southern Hemispheres. In general, at any given point
on Earth, only around 50% of the sky will be visible. We can understand this by
considering the atmosphere as a sphere around the earth. The sky any person can
view at one point can be compared to a giant dome equal to half of the sphere.
And because the Earth rotates, the dome we can see changes, unless one is
sitting directly on the North or South Pole.</span>
