A container with a volume of 893L contains how may moles of air at STP?

Answers

Answer 1

Answer:

i think 54

Explanation:

Answer 2

In the container with a volume of 893 liters, there are 39.9 moles of air at STP conditions.

We can find the number of moles with the Ideal gas law equation:

[tex] PV = nRT [/tex]

Where:

P: is the pressure = 1 atm (STP)

V: is the volume = 893 L

n: is the number of moles =?

R: is the gas constant = 0.082 L*atm/(K*mol)

T: is the temperature = 273 K

Hence, the number of moles is:

[tex] n = \frac{PV}{RT} = \frac{1 atm*893 L}{0.082 L*atm/(K*mol)*273 K} = 39.9 moles [/tex]

Therefore, there are 39.9 moles in the container.

sound travel through water at a speed of 1500 m/s. if the frequency of a sound is 1000 Hz, what is the wavelength?

Answers

Answer:

λ = 1.5 m

Explanation:

Given data:

Speed of wave = 1500 m/s

Frequency of sound = 1000 Hz

Wavelength of sound = ?

Solution:

Speed of wave = frequency × wavelength

by putting values,

1500 m/s = 1000 Hz × λ

λ = 1500 m/s / 1000 s⁻¹ (Hz = s⁻¹ )

λ = 1.5 m

Answer: 1.5

Explanation:

Well first you do

1500/ 1000= 1.5 which mean

The wavelength is 1.5

WHAT TWO PLANT CELLS DONT PRODUCE PROTINES?!?!?!?!?

Answers

Plant cells have a distinct set of features and characteristics. They are different to the cells of organisms from other kingdoms of life.

The cells of plants are eukaryotic. A eukaryotic cell is any cell with a ‘true’ nucleus and organelles. This immediately separates plant cells from the cells of bacteria and archaea.

Animals and fungi also have eukaryotic cells. Plant cells have a unique set of organelles that distinguishes them from the cells of animals and fungi. The presence of organelles called chloroplasts, vacuoles and a cell wall are three key features of the cells of plants.

Plant cells are relatively large and can differ considerably within a plant. There is a large diversity of different types of cells found through stems, leaves and roots.

Different types of plant cells

There is a wide range of cells found in plants. Within the leaves alone there is a variety of cells that perform different functions such as providing protection, photosynthesizing or transporting water. They same level of variety occurs in stems, roots and flowers. Here I describe only a few of the different types of cells from different parts of a plant.

Answers

Answer:

To ensure that everyone enjoys using your pool, it is important to keep the swimming pool pH levels in balance at all times. If the pH is too high, it could cause skin irritation and corrode metal parts on the pool. If the pH is too low, it could create a situation where the chlorine in the pool isn't as effective.

Choose the statements below that are correct regarding the nature of protons and neutrons. Choose ALL statements that are correct.
a. protons and neutrons are found around the outer edge of the atom
b. protons and neutrons have approximately the same charge
c. protons and neutrons are found in the nucleus
d. protons and neutrons have approximately the same mass

Answers

Answer:

c. protons and neutrons are found in the nucleus

d. protons and neutrons have approximately the same mass

Explanation:

There are three fundamental particles within an atom which are the protons, neutrons and electrons.

The protons are the positively charged particles within an atom

Neutrons do not carry any charges

Electrons are the negatively charged particles.

Both the protons and neutrons occupy the tiny nucleus at the center of the atom. The electrons moves round the nucleus through the orbital space. The mass of the protons and neutrons are similar and are assumed to be approximately the same.
