it takes a slug 20 minutes to travel from the grass to the trash can a trip of 15 meters. how far could the slug travel in 60 minutes

Answer:

Human cells are eukaryotic which means they are more complicated, bacteria cells are prokaryotic which means they are simpler and viruses are not even cells at all, they are just genetic material in a protein shell. Not all bacteria make us sick, most actually help us have emunity to the virus. Hope this helps

Explanation:

Answer:

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function.

Explanation:

Answer: 212 g  of sodium carbonate must react

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.

In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.

The balanced chemical equation is:

[tex]Na_2CO_3+CaCl_2\rightarrow 2NaCl+CaCO_3[/tex]

Mass of products = mass of  sodium chloride + mass of  calcium carbonate = 233 g+ 201 g= 434 g

Mass of reactants= mass of sodium carbonate  + mass of calcium chloride =x + 222 g

As the mass of reactants should be equal to mass of products

434  = x  + 222 g

x = 212 g

Thus 212 g  of sodium carbonate must react with 222 g of calcium chloride to make 233 grams of sodium chloride and 201 grams of calcium carbonate

Id say A. I think I hope I'm right

Answer:

As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.

Answer:

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.

Answer:

Protons, positive charge

Neutrons, neutral

Electrons, negative charge

Explanation:

Answer:

B

Explanation:

2H2→Hydrogen peroxide

O2→oxygen

"A water molecule (formally known as dihydrogen monoxide) is composed of two hydrogen atoms and one oxygen atom. ... The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy"

"A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction."

The answer is B, hope this helps :)

Answer:

Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers. For example, let us assume 2 molecules CO (carbon monoxide) and CO2(carbon dioxide).

Explanation:

The acids react with the chemical composition of the rock causes the disintegration of the rocks.

Chemicals when react with the chemical components of the rocks cause the disintegration of the chemical and physical structure of rocks which cause breakage of rocks into parts. This process is called chemical weathering.

For example, the sulfur dioxide gas in the air reacts with the water in the air to form the acid rain.

The acid rain reacts with the chalk or limestone rock that causes the disintegration of the chemical structure and physical structure of rock causing breakage of the chalk or limestone.

Displacement is defined as the distance, in any direction, of an object relative to the position of another object. Physicists use the concept of a position vector as a graphical tool to visualize displacements. A position vector expresses the positionof an object from the origin of a coordinate system

Radiant Energy

Explanation:

Radiant energy is created through electromagnetic waves

Answer: The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be. The example of iron rusting illustrates an inherently slow reaction.

Answer:

they are either donated to or taken by another atom to achieve octet arrangement

Explanation:

for example Na+ and Cl- .. they both have one extra and one less electron .

so they donate and receive one electron to/from each other to achieve the octet arrangement ..

Answer:

First blank: spiral arms

Second blank: center

Explanation:

It takes 21.3 days

Given

5 hr = 8 kg Alcohol

Required

Days to consume 1000 kg of glucose

Solution

Alcoholic fermentation⇒ glucose produces ethanol and carbon dioxide,

C₆H₁₂O₆ → 2 C₂H₅OH + 2CO₂

mol ethanol :

[tex]\tt \dfrac{5000~g}{46~g/mol}=108.7~moles[/tex]

moles of glucose to produce 108.7 moles ethanol :

[tex]\tt \dfrac{1}{2}\times 108.7=54.35[/tex]

54.35 moles = 5 hours

moles of 1000 kg of glucose :

[tex]\tt \dfrac{10^6~g}{180~g/mol}=5555.5~moles[/tex]

So for 5555.5 moles, it takes :

[tex]\tt \dfrac{5555.5}{54.35}\times 5~hours=511.085~h=21.3~days[/tex]
