Two liters of oxygen (O2) is collected over water at 20oC. If the total pressure in the container is 95.00 kPa, what is the part
garri49 [273]

Answer:

THE PARTIAL PRESSURE OF OXYGEN GAS IN THE CONTAINER IS 92.67kPa WHICH IS OPTION B.

Explanation:

To calculate the partial pressure of oxygen gas collected over water, we use

Ptotal = Poxygen + P water

It is worthy to note that when oxygen is collected over water, it is mixed with water vapor and the total pressure in the container will be the sum of the pressure exerted by the oxygen gas and that of the water vapor at that given temperature.

At 20 C, the vapor pressure of water as given in the question is 2.33 kPa.

Using the above formula,

Ptotal = Poxygen + P water

Substituting for Poxygen, we have;

Poxygen = Ptotal - P water vapor

P oxygen = 95 .00 kPa - 2.33 kPa

P oxygen = 92.67 kPa.

The partial pressure of oxygen gas in the container is hence, 92.67kPa.

When a stone is dipped in a glass containing some water, the level of water rises but when a
sladkih [1.3K]

Explanation:

It's so because we know that stone is insoluble, ain't it, so it takes space in water & the water level rises.

But, when a spoon of sugar is added to water, it is soluble & hence mixes with water, so it doesn't rise.

I Hope this helps! (ㆁωㆁ)

Scientific notation of (4.5+ 17) x 104 -1.5 x 104
Naddik [55]

Answer:

4.5× 104 + 1.7× 105. Firstly, we need to ensure that both exponents have the same value. Thus, we need to change the value of 1.7 x 105 to 17 x 104. If both already had the same exponential value, you can neglect this step. 4.5× 104+ 17 × 104. Now, we will take exponentials common and add the decimal values. (4.5+ 17) × 104 | 21.5 × 104. Similar steps are taken for the subtraction phase we just need to retrace our steps and find differences rather than sums. These lessons and worksheets show you how to perform sums and differences with values that are in scientific notation.

An ion from a given element has 38 protons and 36 electrons what is the charge
den301095 [7]
For a neutral atom, the number of positive protons is equal to the number of negative electrons and the charge is zero.

For this question, we see that the number of protons exceeds the number of electrons by 2, which means that this ion in a positively charged charged ion with charge of +2.
