Oxygen is a gas that is present in the atmosphere, to mix with air. Oxygen is the most needed gas. It is used by living beings in breathing. Oxygen is needed for the breakdown of food molecules in living organisms. Oxygen is taken by hemoglobin present in the blood. This process is called respiration.

Carbon dioxide is also a gas that is present in the atmosphere. This gas increases the warmth of the earth. These are greenhouse gases. This is present 0.03 %.

CO₂ has two molecules of oxygen, as written here.

Given, 12CO₂

The 12 moles are multiplied by 2 moles of oxygen, which is equal to 24 moles total.

12 x 2 = 24

Therefore, there are 24 atoms of oxygen in 12CO₂.

(1.08, 2.04, MC)THE WORLD WITH A THOUSAND MOONSCHAPTER 1: Thrill CruiseBy Edmond HamiltonLance Kenniston felt the cold realization of failure as he came out of the building into the sharp chill of the Martian night. He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl.""Sure, let's try it anyway," Holk Or agreed.With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.Read the following lines from the text:And for lack of one of those ships, his hopes were ruined!This line suggests Kenniston is (3 points) adesperate bangry cdramatic drealistic GIVING BRAINLIEST Salva belongs to the Dinka tribe, and he can tell by her clothing that the woman is from the Jur-chol tribe. *Do we have tribes in our country or ways to show we belong to a group? *How are people identified as being in a certain group? *Do we use different clothes as African tribes do? *Are there other ways we set ourselves apart from others?Write a 150-word response (a nice sized paragraph), and answers these questions in paragraph form.Book: A long walk to water The Taliban believe girls should not be educated, or for that matter, even leave the house.
