Answer: The correct matching sequence is:
1 -D , 2-C, 3-E, 4-B , 5-A
Explanation:
Weather maps/satellite:These are the satellites used to monitor the climate on the Earth in day and night.Like moc=vment of clouds, El Nino. La Nina ertc
Doppler radar is a system used to track the velocity or motion of the rain , storm or precipitation.It emit microwave signals to check the change in frequency of the wave due to the motion of the particles.
Radiosonde is an instrument carried away by balloon or any other means into different layers of atmosphere and sends information via radio.
Wind vane is an instrument used to show the direction of the wind. P
Psychrometer is an instrument used to measure atmospheric humidity.It consist of two thermometer that is wet bulb thermometer and dry bulb thermometer.
Match each weather instrument with its description.
- weather maps/satellite - used to help track air masses and fronts
- Doppler radar - uses frequency waves to track particle movement
- radiosonde - carried with a weather balloon
- wind vane - points in the direction winds are coming from
- psychrometer - uses two thermometers; a dry and wet bulb

Now I know how to do equations like this, just a bit confused on how to use my conversion factors.
Do I need to use the 3.0 Molarity in this equation or can I just use Molar Volume of a gas (22.4L/1 mole)?
Answers
You would have to use the molarity of calcium hydroxide to find the moles of calcium hydroxide. Once you have moles, just convert using mole:mole ratio and find the grams of sodium hydroxide.

Answer:
27.3 L
Explanation:
Final answer:
To calculate the volume of the balloon at a certain height, we can use the combined gas law. The volume of the balloon at the new height is approximately 1.13 L.
Explanation:
To solve this problem, we can use the combined gas law, which states that the ratio of the initial pressure, volume, and temperature will be equal to the ratio of the final pressure, volume, and temperature.
Using the formula PV/T = constant, we can set up the equation (1.00 atm * 2.30 L) / (23.5 + 273.15 K) = (0.810 atm * V) / (12.0 + 273.15 K), where V is the volume of the balloon at the new height.
Simplifying the equation and solving for V, we find that the volume of the balloon at the new height is approximately 1.13 L.

**NOTE: The volume as indicated in this question is defined in L, not mL, so that conversion must be made. However it is 1000 mL = 1 L.
So now we can assign values to these variables. Let us say that the 18 M
We can then solve for
We now know that the total amount of volume of the 4.35 M solution will be 210 mL. This is assuming that the entirety of the 50 mL of 18 M is used and the rest (160 mL) of water is then added.
