What activation energy was used to start the chemical reaction in the burning marshmallow?

Answers

Answer 1

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, let's understand some terms

Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.

The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.

He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?

Answers

Answer:

If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it.

What is the concentration of the CaCl2 (calcium chloride) salt solution if you are given 3.2g of CaCl2 and you add 4ml of water? The units for your answer should be mg/ml.

Answers

Answer:

800 mg/ml

Explanation:

Recall that: 1 g = 1000 mg.

Hence

3.2 g of CaCl2 =  3.2 x 1000 = 3200 mg CaCl2

mass concentration of CaCl2 = mass of CaCl2/volume of water

                                   = 3200/4 (mg/ml)

                                   = 800 mg/ml

Therefore, the concentration (in mg/ml) of CaCl salt solution formed by dissolving 3.2g of CaCl2 in 4 ml of water is 800 mg/ml.

The concentration of calcium chloride solution will be 800 mg/ml.

The calculation of the concentration of CaCl₂:

Based on the given information,

The mass of CaCl₂ given is 3.2 grams. The volume of water is 4 ml.

Now the concentration of CaCl₂ can be determined as,

Concentration = Mass/Volume

Now putting the values we get,

[tex]Conc = \frac{3.2 g}{4 ml} \\Conc = 0.8 g/ml\\Conc = 0.8 g * 1000 mg/ml\\Conc = 800 mg/ml[/tex]

Thus, the concentration of CaCl₂ is 800 mg/ml.

true or false ? Cell membranes are selectively permeable, allowing only some materials to cross the cell membrane. This
property allows cells to maintain homeostasis.

Answers

Answer:

True

Explanation:

Cell membranes are selectively permeable because of the structure of the phospholipid bilayer.

This bilayer only lets certain things in because it depends on the polarity, size,  and type of molecule.

For example, glucose molecules are too large to enter. But, carbon dioxide molecules can go in and out easily because of their small size.

Answer:

This statement is True

“One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.”

Choose the best description, definition for Uniformitarianism. Please help im failing badly

Answers

Answer:

The correct answer is b. The principle of Uniformitarianism is based on the idea that Earth´s physical landscape is the result of processes and forces that have happened uniformly since the earth formed.  

Explanation:

Stated by the geologist James Hutton, this principle says basically that all the geological processes that currently occur had also occurred in the past. Based on this principle, many events might be explained, and not only geological events, but also biological events.

The Uniformitarianism or Uniformism principle states that all the processes that have occurred during the whole Earth history, have been uniform (that is why this principle is named Uniformitarianism) and similar to the current processes.

This principle is very important nowadays, but knowing that not all processes are completely uniform, they have been changing heir intensity and rhythm. Besides, there is a very important factor that is not repeatable, living organisms, that have been lineally changing throughout history.
