If I use the dropper to add 10 mL of drink mix to 50 mL of water, what is the
percent by volume of the drink mix in the solution? Percent by volume is
calculated the same way as percent by mass, but instead of mass, place the
volume of the solute in the numerator (top) and the volume of the solution in the
denominator (bottom).

Answer:

9. b

10. a

Density would have to do with if the powder is floating or sinking, conductivity would have to do with heat and mass would have to do with weight, leaving solubility as the only reasonable answer.

Explanation:

Answer:

A. Antibiotic resistance can sometimes be shared among bacteria.

B. Mutation can cause antibiotic resistance.

D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection.

Explanation:

Identifying: Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). ... Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.

Hope this helps, I reported some answer that was absurd, not applicable, incomplete and confusing

Mutation can cause antibiotic resistance, Bacteria that become resistant are an example of evolution. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection The correct options are B, D, and C.

Archaea, like bacteria, lack interior membranes but have a cell wall and swim with flagella.

Archaea differ from bacteria in that their cell wall lacks peptidoglycan and their cell membrane contains ether linked lipids rather than ester linked lipids.

The dispersion of antibiotic resistance in pathogenic bacteria is a simple and elegant example of natural selection at work.

Bacteria can develop antibiotic resistance through mutations that alter antibiotic cellular targets or by acquiring dedicated resistance genes from other bacteria.

Antibiotic resistance can be caused by mutation; bacteria that become resistant are an example of evolution. Natural selection is demonstrated by antibiotics killing bacteria while allowing mutated bacteria to live.

Thus, B, D, and C are correct options.

Answer:

When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation

Answer: 22.33 M

Explanation:

molarity = moles of solute/liters of solution or [tex]M=\frac{mol}{L}[/tex]

first we have to find our moles of solute (mol), which you can find by dividing the mass of solute by molar mass of solute

mass of solute: 285 g

molar mass of solute: 36.46 g/mol

let's plug it in:

[tex]\frac{285g}{36.46 g/mol} = 7.817 mol[/tex]

next, we plug it into our original equation:

[tex]\frac{7.817 mol}{0.350 L} = 22.33 M[/tex]

Answer:

Temperature will revert to room temperature after the substance reacts fully. Heat energy flows between the chemical bonds of the added substance and water to the surroundings (elsewhere in the water, the beaker, a student's hand that touches the beaker).

Explanation:

Hot packs and cold packs eventually return to room temperature because of thermal equilibrium

Temperature is the degree of hotness or coldness of a body. We have to note that bodies often tend to attain thermal equilibrium with the surroundings. Hence heat flows from or to the body as required.

Hence, the need to attain thermal equilibrium with the  environment is the reason why hot packs and cold packs eventually return to room temperature.

Answer:

Heat is the transfer of energy

Explanation:

Heat refers to the energy transferred from a hotter object to a cooler one. Heat is transferred in three ways: radiation, conduction, and convection. Radiation is the direct transfer of energy. The direct transfer of heat from one substance to another substance that it is touching is called conduction.

Hey there!:

Molar mass :

Fe₂O₃ = 159.69 g/mol

O₂ = 31.99 g/mol

By reaction stochiometry  :

4 Fe + 3 O₂ = 2 Fe₂O₃

3 * (31.99 g O₂ )  ------------------  2 * ( 159.69 ) g Fe₂O₃

8.93 g O₂ --------------------------- ( mass O₂)

mass O₂ =  ( 8.93 * 2 * 159.69 ) /  ( 3 * 31.99 )

mass O₂ = 2852.0634 / 95.97

mass O₂ = 29.71 g Of Fe₂O₃

Answer:

i think it is..... smaller than normal range of highs and low tides  

Moon and Sun are at right angles to the Earth

Explanation:

Moon and Sun are at right angles to the Earth and gravity of the Sun and Moon work against is the right statement about NEAP tides.

Tides are the cyclic deformation of water body occur due to external gravitational force.

NEAP tides are also known as small tides as their heights are not very much and this is occur due to opposite attraction of water towards the gravity of the sun and moon. As sun and moon are present in the right angle direction with respect to the earth.

Hence, option (1) & (2) is correct, i.e. gravity of sun and moon is opposite and they are present at the right angle to the earth.

Explanation:

Answer:

110moles

Explanation:

Molarity, which refers to the molar concentration, can be calculated using the following formula:

Molarity (M) = number of moles (n) ÷ volume (V)

n = molarity × volume

According to the provided information in this question, a solution with a molarity of 5.5M and a volume of 20L is involved.

n = 5.5M × 20L

n = 110moles

110moles of solute are present.
