Explanation:

Volumetric flasks

Volumetric labware is for measuring liquids with precision. Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ±0.02.

Answer:

A pipette is a laboratory instrument used to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).

Answer:

Not all plants do need soil to grow

Explanation:

Not all plants need soil to grow. Some just do better in soil compared to other growing mediums. What plants need are minerals and nutrients, such as nitrogen, potassium, and phosphorous. Soil is an effective way of delivering those nutrients cost-effectively. You can also use alternative delivery systems like hydroponics, aeroponics, and aquaponics to achieve the desired effect. However, these are only suitable for growing shallow-rooted plants. Plants with deep roots will always need soil, as will larger plants with spreading roots.

The apple, that innocent bud of an Americana autumn, has pulled off one of the greatest cons of all time. As students across the country prepare to greet a new school year and teacher with a polished bit of produce, the apple cements its place in the patriotic foods pantheon despite its dodgy past.

Answer:

If students brought an extra snack for their teachers it doesn't necessarily mean their grades would increase, but it's not impossible. A lot of teachers today might view it as being something like a suck-up. However, I do know that there are teachers who might be touched by such gestures and give the students extra attention, with this their grades might improve with the extra attention.

Answer:

An alcohol with three other carbons attached to the carbon with the hydroxyl group

An alcohol with two other carbons attached to the carbon with the hydroxyl group

Explanation:

If we look at 3-ethyl-3-pentanol, we will discover that the compound is a tertiary alcohol. That is, the carbon atom bearing the hydroxyl group is attached to three other carbon atoms as gown in image 1 attached.

For 2-hexanol, the carbon atom bearing the hydroxyl group is attached to two other carbon atoms hence the alcohol is a secondary alcohol. The compound is shown in image 2 attached.

Answer: option A

The electrons are attracted to the protons

Explanation:

Electrostatics is a force that pull or push objects without the objects actually touching them.

Electrons have a negative charge and protons have a positive charge. Positive and negative attract each other so therefore the electrons are attracted to the protons.

It’s not B because the electrons aren’t 100% pushing away from the nucleus.

It’s not C because the electrons are not attracted to the neutrons. Neutrons don’t have a charge; they have a net zero charge.

It’s not D because the electrons can’t attract each other. Electrons have a negative charge and negative charges don’t attract each other; they push away from each other instead.

Hope that helps.

The correct lewis structure of methane(CH4)

C. H:C:H:H

Answer:

Ver las respuestas abajo.

Explanation:

Este problema se puede resolver conociendo la relacion entre horas y minutos, sabemos que:

1 hora [h] → 60 minutos [min]

De esta manera:

2 [min] = 2/60 = 0.033 [h]

15 [min] = 15/60 = 0.25 [h]

30 [min] = 30/60 = 0.5 [h]

10 [min] = 10/60 = 0.166 [h]

6 [min] = 6/60 = 0.1 [h]

20 [min] = 20/60 = 0.33 [h]

5 [min] = 5/60 = 0.0833 [h]

Answer:

Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge. Ions are atoms that have gained or lost electrons.

Answer:

BIOHEAT is a biodiesel mix that can be utilized (without equipment changes) in most home heaters. BIOHEAT promptly diminishes various hurtful discharges from heater use (up to 80% contingent upon blend used) and the oil is made from nearby feedstocks like utilized cooking oil

Answer:

Changing the concentration of one solution in the cell will increase the voltage potential of the cell because you are putting the system further out of equilibrium. Because the concentration in only one side of the cell has changed, the concentration gradient across both sides of the cell becomes steeper. In order for this experiment to work, the salt bridge must be concentrated enough to effectively separate the two electrolyte solutions, but it must also be porous enough to allow ionic flow.

7.95 × 10

= 79.5

This is the answer

Because there are 6 carbon molecules in 2-octene, we will place down 6 carbons. Carbons usually form a backbone, so they will be lay in a flat line. You can then add 3 H on both the Hydrogens at the ending to create symmetry, and keep filling Hydrogen on both sides and try to creat symmetry until you only have 2 H left. Place 1 H above a C and 1 H below a C so the remaining 2 carbons can then double bond to each other and form a complete octet.

The correct answer is Sr-84. The lightest specie is the most deflected while the heaviest specie is the least deflected.

In mass spectroscopy, chemical substances can be identified by looking at their respective mass-to-charge ratios of gaseous ions in electric and magnetic fields. The is achieved using a mass spectrometer.

The lightest specie undergoes the greatest deflection while the heaviest specie undergoes the heaviest deflection accordingly in a mass spectrometer.

In this case, Sr-84, is the lightest specie hence it should be the least deflected specie.

Answer:

The answer is "1.8 g diamond includes 9.03e22 atoms".

Explanation:

Given:

Weight of 9-carat diamond = 1.8 g

 [tex]\therefore\\\\[/tex]

weight of 1-mole carbon  =12 g

[tex]\because[/tex]

calculating the moles which are available into  18 g carbon weight:

 x= Carbon moles weight in 1.8 g

[tex]1 - mol\ C = 12 g\\\\x - mol\ C = 1.8 g\\\\\to x = \frac{(1.8 \ g \times 1\ mol\ C)}{ 12 \ g}\\\\\to x = 0.15\ moles[/tex]

In 1 mole element associated with Avogadro's number that is [tex]6.02 \times 10^{23}\\\\[/tex]

 Carbon includes in 1 mol[tex]=6.02 \times 10^{23}\ atoms\\\\[/tex]

0.15 mol of carbon includes:

[tex]= 0.15 \times 6.02 \times 10^{23} = 9.03 \times 10^{22}\ atoms.[/tex]

Using the scientific notation:

0.15 mol of carbon includes:  9.03e22 atoms. So,   1.8 g diamond includes 9.03e22 atoms.
