Decreasing the concentration would decrease the reaction rate (option c)

The aforementioned statement is due to the fact that when a substance's concentration is high, it will quickly perform the chemical reaction as there are more particles reacting with one another. Conversely, if there is less of a concentration, then the reaction rate would decrease as there are little particles reacting with one another.

Joseph drives 25miles North in 15 minutes then he drives 40 miles east in 30 minutes, then he uses cruise control option for 1 h
Musya8 [376]

Answer: 1.25 miles per minute

Explanation:

Average speed is the rate of change of total distance covered per unit time.

i.e Average speed = (Total distance / Time taken)

Total distance covered = (25miles + 40 miles + 70 miles + 15 miles)

= 150 miles

Total time taken = ( 15 minutes + 30 minutes + 1 hour + 15 minutes) = 120 minutes

Since 60 minutes = 1 hour, the total time taken is 120 minutes

Now, apply Average speed = (Total distance / Time taken)

= (150 miles / 120 minutes)

= 1.25 miles per minutes

Thus, Joseph drove with an average speed of 1.25 miles per minute.

Step 2: measure the area of the top of the syringe
Elena L [17]

I am unsure if this is correct, but this might be the whole section:

  • The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. <em>Answer: </em><em>3.60 </em><em>cm</em>
  • Divide by two to find the radius. Maintain significant figures. <em>Answer: </em><em>1.80 </em><em>cm</em>
  • Substitute the radius into the formula A = πr² to find the area of the top of the syringe. Maintain significant figures. <em>Answer: </em><em>10.2 </em><em>cm²</em>
