how to use a microscope> Everything I need to know

Answers

Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
Always keep your microscope covered when not in use.
Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.

Step 1: Set Up the Microscope. ...
Step 2: Clean the Lens. ...
Step 3: Prepare a Slide. ...
Step 4: Insert the Slide. ...
Step 5: Set Up for Viewing. ...
Step 6: Set the Light Control. ...
Step 7: Focus the Microscope. ...
Step 8: Increase Magnification.

Answer:

Keep in mind this changes from microscope to microscope.

Explanation:

On most classroom microscopes, there will be two knobs on either side of the scope. These will increase or decrease the height of the "stage", which is how you "focus" the microscope. The larger knob will move the stage the most, and thus, is called the coarse focus. The smaller knob is called the fine focus, and, you guessed it, will move the stage the least. There are usually three "objective lenses". Each will have a different magnification and will be listed on the lens itself. It rotates around the "revolving nosepiece". MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!! If you don't you WILL break the slide and you WILL get death looks from the teacher.

On the stage, there are two clips. They move NOT up and down, but they spin. what you want to do is to move the slide into the clips. They will not break if you do not bend them more than what the slide will bend them to.

The technique for focusing the microscope is really easy once you do it a few times. After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible. Once you do that, from there use the fine focus knob to make the object most visible.

These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.

The direction in which heat flows in a system is that: B. heat flows from an object of higher temperature to an object of lower temperature.

What is heat?

Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from one object (body) to another, especially due to a difference in temperature.

This ultimately implies that, heat is primarily transferred between objects that have different degrees of temperature during the process of heat conduction.

According to the kinetic-molecular theory, heat is generally transferred from a hotter object with higher temperature to a cooler object with lower temperature.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

D. 8
PLEASSSSSSSE ANSSSSWER ALL THE QUESTIONS------------

Answers

1.) A
2.)B

Explanation:

The total mass of products obtained in the reaction; CaCO3→CO2+CaO is 30 grams. Given the reaction; Fe+O2→Fe2O3, atoms of Fe and O2 are rearranged during the reaction. During a chemical reaction, mass is conserved. Given the reaction NaHCO3+HC2H3O2→NaC2H3O2+H2O+CO2, we can see that the atoms of the reactants are regrouped during the reaction. Given the reaction 2H2+O2→2H2O, there are four atoms of hydrogen before and after the reaction.

According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. Similarly, mass is neither created nor destroyed.

This means that the number of atoms of each element before and after the reaction must remain the same. A chemical reaction only involves the rearrangement of atoms in reactants to form products.

The total mass of reactants must be equal to the total mass of products according to the law of conservation of mass.
