_______ have cells that are all dried out.

Answer:

I'm pretty sure a lot of them are melting because of global warming

Answer:

5.83 M

Explanation:

3.5 M * 125.0 ml  =  M₂ * 75.0ml

437.5 M.ml = M₂ * 75.0 ml

M₂ = 437.5 M.ml / 75.0 ml

M₂ = 5.83 M

Answer:

1.25 mL/s

Explanation:

Your are told that 25.0 mL of H2 was produced 20 seconds. This is equal to rate 25/20 = 1.25 mL/s

When a reaction progresses, the reactant concentration gradually decreases and the product concentration gradually increases. Here the rate of the reaction is 1.25 mL/s.

The rate of a chemical reaction is defined as the rate of decrease of concentration of a reactant or the rate of increase of concentration of a product. The rate of the reaction is usually expressed in units mol L⁻¹s⁻¹. The rate of the reaction are affected by several factors like concentration of the reactants, temperature, etc.

An equation which expresses the experimentally observed rate of a reaction in terms of the molar concentration of the reactants which determine the rate of the reaction is called rate equation.

Here it is seen that 25.0 mL of H2 was produced 20 seconds. So the rate is given as:

Rate = 25/20 = 1.25 mL/s

Thus the rate of the reaction is 1.25 mL/s.

Explanation:

Some of the glucose required for cellular respiration in humans is obtained by external food source which are rich in carbohydrates.

Cellular respiration is the process in which cells combines the oxygen with the foodstuff molecules, and converting the chemical energy into life sustaining activities as energy.

In the human body, we get the glucose for the cellular respiration from the external food source which are riched in carbohydrates, starch, etc. After converting the chemical energy to glucose then oxygen is absorbed in the lungs and circulate the blood through out the body by red blood cells.

Hence, we get glucose from food source.

Answer:

pH = 10.75

Explanation:

To solve this problem, we must find the molarity of [OH⁻]. With the molarity we can find the pOH = -log[OH⁻]

Using the equation:

pH = 14 - pOH

We can find the pH of the solution.

The molarity of Ca(OH)₂ is 2.8x10⁻⁴M, as there are 2 moles of OH⁻ in 1 mole of Ca(OH)₂, the molarity of [OH⁻] is 2*2.8x10⁻⁴M = 5.6x10⁻⁴M

pOH is

pOH = -log 5.6x10⁻⁴M

pOH = 3.25

pH = 14-pOH

Answer:

C. 1/32

Explanation:

A possible solution for maximizing the percentage of hydrogen in discarded wood is to design a machine that can collect more effectively all the gases and separate hydrogen from other gases.

Discarded wood and other products can still produce important elements nitrogen, methane, and hydrogen. This is possible through combustion that releases these elements in a gas.

This is a new method and it is still not completely developed. Due to this, the equipment is not as efficient as one would like, for example, all gases are initially collected together but this is a problem if only one gas is needed.

Based on this, a potential solution would be to create a machine that is more efficient in collecting and separating the gases.

Answer:

Endothermic

Explanation:

An endothermic reaction is one in which energy is absorbed while an exothermic reaction is one in which energy is given out(evolved).

If we look at the reaction as written; 3C(graphite) + 3H2(g) + 88kcal -------> C3H8(g), we will notice that;

i) 88kcal of energy had to be absorbed for the reaction to occur

ii) The enthalpy change for the reaction is positive.

Since energy must be taken in to drive the forward reaction, then the reaction is endothermic as written.

The concentration of the 3.2 g of sodium chloride in 8 dm³ of water is 6.845 × 10⁻³ M

Explanation:

The concentration of a solution is given as either the ratio of mass to volume, or the ratio of volume to volume or as molarity

[tex]Concentration, C = \dfrac{Mass}{Volume} = \dfrac{Volume}{Volume} = \dfrac{Number \ of \ moles }{Liters \ of \ solution}[/tex]

The number of moles present in 3.2 g of sodium chloride, 'n', is given as follows;

[tex]n = \dfrac{Mass}{Molar \ mass}[/tex]

The molar mass of sodium chloride, NaCl = 58.44 g/mol

n = 3.2 g/58.44 g/mol = 0.0547570157 moles

8 dm³ = 8 Liters

Therefore, the concentration, C = 0.0547570157 moles/(8 liters) = 6.845 × 10⁻³ M

The concentration of the 3.2 g of sodium chloride in 8 dm³ of water = 6.845 × 10⁻³ Molar solution.

Explanation: I'm sure its that answer

Answer:

Due its storing and holding ability.

Explanation:

It matter that the material from which the vat is made is metal because this vat is used for storing and holding liquids. Vat is a large container or tank that is used for storing or holding liquids in industrial sector. This vat is made of metal which increases its strength and durability. If the vat is made of wood or plastic so it can't hold huge amount of liquid or chemical due to its weak material so that's why it matters that the substance from which the vat is made is metal or not.
