The coefficient of any substance in a chemical equation indicates the number of moles of that substance which are present. We can see from its chemical formula that tetraiodine nonaoxide contains four iodine atoms and nine oxygen atoms. If the coefficient is two, then the total iodine atoms will be eight and  the total oxygen atoms will be 18. Because the law of conservation of mass holds, an equal amount must be accounted for on the other side of the chemical equation. Therefore, the first option is correct.

27. Scott travels north 5 miles and then goes west 3 miles before coming straight back south 2 miles. What is his distance? *
belka [17]

Scott traveled 10 miles in his journey.

<u>Explanation</u>:

Scott first travels 5 miles in north direction, then he turns to west and covers 3 miles distance finally he turns to south and travels 2 miles. We need to find the total distance covered by the Scott. To find the distance we should sum up all the distances he covered in three directions 5 miles north + 3 miles west + 2 miles south = 10 miles.

Therefore we can conclude that the total distance traveled by the Scott is 10 miles.

Which of the following organisms are carnivores?
sineoko [7]

Answer:

Secondary consumers

Explanation:

Carnivores are organisms that only eat meat and that rely on others for food and energy; this means that they cannot produce food themselves.

Look at the answer choices:

- Decomposers: these are organisms that break down dead matter into material that can be used later by plants to grow; carnivores do not break down dead matter; rather, they eat meat.

- Primary consumers: these are usually herbivores; they are the second level of the energy pyramid, and they eat the organisms at the bottom level. The organisms at the bottom level are plants that make their own food. Obviously, plants are not meat, so carnivores are not primary consumers.

- Producers: these are the plants at the bottom of the energy pyramid that make their own food. Carnivores do not make their own food.

Thus, the answer is secondary consumers because this level of organisms eat the organisms at the primary consumer level.

Hope this helps!

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?
arsen [322]

Answer:

92.65256 cm^3

Explanation:

To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.
