Answer: capillaries are not used to exchange substances between the body cells

Explanation:

Arteries carry blood away from the heart. Veins carry blood to the heart except the hepatic portal vein. Capillaries are used to exchange substances between body cells.

Answer:

Sample B has the highest specific heat

Explanation:

Specific heat of a material is defined as the heat necessary to increase in the temperature of 1g of material in 1°C.

The material with the highest specific heat requires more energy to increase its temperature.

In the problem, sample A and B are under the same amount of energy but sample A increases more its temperature. That means sample A has the lowest specific heat and:

Answer:

Do you mean acids?

Due to chemical reaction

Explanation:

Acids are only stored in glass containers because glass containers rarely react with any substance.They dont react with acids and prevent chemical reaction so the acids can be kept. If acids were kept in metal containers it would react .

Answer: NaOH and Ca(OH)2 are bases. HCl and H2SO4 are acids

Explanation:

If we subtract the atomic number from the atomic mass: atomic mass - atomic number = number of protons + number of neutrons - number of protons. Thus we get the number of neutrons present in an atom when we subtract the atomic number from the atomic mass.

Explanation:

Completely turn off equipment like televisions and stereos when you're not using them.

Choose energy-efficient appliances and light bulbs.

Save water.  

Lower your shades or close your curtains on hot days, to keep the house cool and reduce the use of electric fans or air-conditioning.

Let clothes dry naturally.

Keep lids on pans when cooking to conserve energy.

Use rechargeable batteries.

According to molar concentration, 100 ml of 10 M solution is needed to make 1 liter of a 1 M solution.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case of two solutions, molar concentration is found out by, M₁V₁=M₂V₂.

On substitution in above formula, V₁=1×1/10=0.1 L=100 ml.

Thus, 100 ml  of a 10 M solution is needed to make 1 liter of a 1 M solution.

Explanation:

You'll want to use the Ideal Gas Law for this problem.

First, determine your formula. V=nRT/P

Next, determine your factors.

V = ?

n = 847g

R = 0.0821L.atm/mol.k

T = 313k (40+273)

P = 89.4kPa

Now just plug it in!

Answer:

C. So electrons can flow from one electrode to another

Explanation:

An electrochemical cell is any cell in which electricity is produced by reason of a chemical change.

An electrochemical cell consists of two electrodes, these two electrodes are connected using a wire.

Usually, electrons flow from one electrode to another via this wire thereby enabling the electrochemical processes of oxidation and reduction in the cell to proceed effectively.

Answer:

pH = 14 - pOH

pH = -log[H+]

pH = pKa + log [A-]/[HA]

Explanation:

The equation used depends on what is given in the equation.

The expression that represent the pH of the solution is

pH = 14 - pOH

pH = -log[H+]

pH = pKa + log [A-]/[HA]

It is the quantitative measure related to the acidity or the other liquid solutions. It should be range between the 1 and 10^-14. here the numbers be like from 0 to 14.

Hence, we can say that The expression that represent the pH of the solution is

this is just an equation for how to find speed. you can also just use like a meterstick and a stopwatch

Answer:

.0016

Explanation:

For specific heat problems you use the formula :

Q = mcΔT

They've given you the m, c and delta T, so you can plug in those values. (for the temperature change subtract 10 from 40 to see that it grew 30 degrees)

You're looking for Q so leave that variable in the equation. Then solve.

.Q = (8.00)(.384)(30)

Q = 92.16

92.16 J energy will be absorbed by a copper sample.

Given:

Specific heat  capacity, C= 0.384 J/g °C

Temperature, T₁ = 10.0°C and T₂= 40.0°C

Mass, m=8.00 g

We know that,

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (g) of the material when its temperature increases or 1 °C, and its unit is J/g °C.

Heat energy in terms of specific heat energy can be calculated by using this formula:

Q= m. C. ΔT

∵ΔT= change in temperature,

ΔT=40.0-10.0°C=30°C

Now substituting the values in the above formula.

[tex]Q= 8.0*0.384*30=92.16J[/tex]

Hence, 92.16 J energy will be absorbed by a copper sample.
