Answer:

There will be produced 3.5 moles of oxygen (O2)

Explanation:

Step 1: Data given

Number of moles Mercury (II) oxide (HgO) = 7 moles

Step 2: The balanced equation

2HgO → O2 + 2Hg

Step 3: Calculate number of moles of O2

For 2 moles of Mercury (II) oxide (HgO) we produce 1 mol of O2 and 2 moles of Hg

For 7 moles of Mercury (II) oxide (HgO) we'll have 7/2 = 3.5 moles of O2

There will be produced 3.5 moles of oxygen (O2)

What method of forecasting uses averages to predict future weather?
amid [387]

The climatology method of forecasting uses averages to predict future weather.

Answer: B

Explanation

The satellites and advanced technologies have helped meteorologists to forecast accurately.

There are four types of forecasting methods prevailing now.

They are climatology method, persistence method, analog method and trends method.

The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.

The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.

The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.

Marina CMI [18]

Answer:

The final volume in mL is 7.14 mL or 7.1 mL.

Explanation:

1.Use Boyle's Law(P_{1} V_{1}= P_{2} V_{2}). Re-arrange to solve for V_{2}<em> for the final volume.</em>

<em />

<em>2. Plug in values. </em>V_{2} =\frac{(2.7 atm)(4.5 mL)}{(1.7 atm)}  = 7.14 mL
