Consider the reaction of KOH with H3PO4 to form K3PO4 and H2O. If 5.38 g H3PO4 is reacted with excess KOH and 7.97 g of K3PO4 is
balu736 [363]

Answer:75%

Explanation:

First, the balanced reaction equation must be written out clearly as a guide to solving the problem. The molar masses of H3PO4 and K3PO4 are then calculated as they will be consistently required in solving the problem. The theoretical yield is obtained from the amount of H3PO4 reacted. Since 1 mole of H3PO4 yields 1 mole of K3PO4, 0.05 moles of H3PO4 yields 0.05 moles of K3PO4. The mass of K3PO4 is produced is then the product of 0.05 and it molar mass hence the theoretical yield. The % yield is calculated as shown.

Using the information in the passage, rank the types of galaxies by their ability to form new stars, from most to least activity
Alex Ar [27]

Answer:

The correct answer is number 2. Elliptical, Spiral, Irregular.

Explanation:

Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.

So we are going to answer this question with our own knowledge.

The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."

That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.

Scientists still studying the universe and the galaxies to understand the way galaxies are formed.
