Which list has organisms made of different kinds of cells?

Answer:

Ocean Currents

Explanation:

The correct answer is Ocean currents.

When the earth receives solar radiation, a large fraction of this incident radiation is usually absorbed by the oceans and the seas, which become warm. Usually, equitorial regions are the ones that have this phenomenon. Now, when ocean currents are flowing from the equator, they usually carry this warm water with them thereby moving the greatest amount of heat from the equator on its way out.

For example, In the Pacific Ocean, there is a current known as Alaska Current that carries warm water in the northward direction thereby making Anchorage which is Alaska's largest city to have a much mild weather than the inland areas with the same latitude.

Answer:

The gravitational force between the two objects would increase.

Answer:

The gravitational force between the two objects would increase.

Explanation:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Answer:

a. pH → 8.12

b. pH → 10.55

c. pH → 8.38

Explanation:

In this excersise, the first two salts come from a strong base and a weak acid, so the anion will make hydrolisis that can help us, to determine pH.

The  NH₄ClO₄ comes from a weak acid and a weak base. This is an special case.

a. KNO₂ →  K⁻  +  NO₂⁻

NO₂⁻  +  H₂O  ⇄  HNO₃  +  OH⁻        Kb = 1.41×10⁻¹¹

Kb = x² / (0.12 - x)

We can avoid the x in denominator because Kb it is a very low value. This expression is reduced to:

[OH⁻] = √(Kb . 0.12)

[OH⁻] = √(1.41×10⁻¹¹ . 0.12)  = 1.30×10⁻⁶ M

- log [OH⁻] = pOH → - log 1.30×10⁻⁶  = 5.88

14 - pOH = pH → 14 - 5.88 = 8.12

b. NaOCl  →  Na⁻  +  OCl⁻

OCl⁻  +  H₂O  ⇄  HClO  +  OH⁻        Kb = 3.33×10⁻⁷

The same as before, we avoid the x in denominator because Kb it is a very low value.

[OH⁻] = √(Kb . 0.37)

[OH⁻] = √(3.33×10⁻⁷ . 0.37)

[OH⁻] = 3.51×10⁻⁴ M

- log 3.51×10⁻⁴ = 3.45 → pOH

14 - 3.45 = 10.55 → pH

c. NH₄ClO₄ → NH₄⁺  +  ClO⁴⁻

Both ions can make hydrolisis in water. Ammonium can give ammonia and the hypochlorite makes hypochlorous acid.

NH₄⁺  +  H₂O  ⇄  NH₃  +  H₃O⁺      Ka = 5.7×10⁻¹⁰

OCl⁻  +  H₂O  ⇄  HClO  +  OH⁻        Kb = 3.33×10⁻⁷

The reduced expression to calculate pH for this sort of salts, is to make the square root of the product between the Ka constant.

As we have Kb for the HClO, we need to determine the Ka

Kw = Ka . Kb   →  Kw/Kb = Ka → 1×10⁻¹⁴ / 3.33×10⁻⁷ = 3×10⁻⁸

[H₃O⁺] = √(5.7×10⁻¹⁰ . 3×10⁻⁸) = 4.14×10⁻⁹ M

- log [H₃O⁺] = pH → - log 4.14×10⁻⁹ = 8.38

As per the calculations of the pH the solutions of 0.12 M KNO2 and 0.37 M NaOCl and the 0.39 M NH4ClO4 web assign have been made with a significant check on the figures.

Answer:

3.2

Explanation:

i caculated give me a 1 star if incorrect

Answer:

For instance, atoms might be connected by strong bonds and organized into molecules or crystals. Or they might form temporary, weak bonds with other atoms that they bump into or brush up against. Both the strong bonds that hold molecules together and the weaker bonds that create temporary connections are essential to the chemistry of our bodies, and to the existence of life itself. Why form chemical bonds? The basic answer is that atoms are trying to reach the most stable state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons). If atoms don’t have this arrangement, they’ll “want” to reach it by gaining, losing, or sharing electrons via bonds.

Answer: 3.2 grams

Explanation:

took the quiz

The  methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.

Methanol is also known as methyl alcohol or wood spirit, it is the  long series of organic compounds called alcohols, having a methyl group (CH 3) attached with a hydroxy group (OH). Methanol was formerly made by the process of destructive distillation of wood.

Here, 2.8  grams of carbon monoxide reacts with 0.50 grams of hydrogen gas as there are 4 hydrogen molecules add 2.8 + 0.50 × 2 = 3.6 grams.

Therefore, methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.

Answer:

3.00 mol NH₄Cl

Explanation:

Step 1: Write the thermochemical equation for the production of ammonuim chloride

NH₃(g) + HCl(g) → NH₄Cl(s)    ΔH = –176 kJ

Step 2: Calculate the number of moles of NH₄Cl produced if the change in enthalpy is –528 kJ

According to the balanced thermochemical equation, 176 kJ are released when 1 mole of NH₄Cl is produced. The moles of NH₄Cl produced if the change in enthalpy is –528 kJ is:

-528 kJ × 1 mol NH₄Cl/(–176 kJ) = 3.00 mol NH₄Cl

Answer:

355Joules

Explanation:

The amount of heat absorbed can be calculated using the formula:

Q = m × c × ∆T

Where;

Q = amount of heat absorbed in joules

m = mass of substance in grams

c = specific heat capacity of solid (0.727 J/g°C)

∆T = final temperature - initial temperature (°C)

According to the information provided in this question;

Q = ?

m = 12.3g

∆T = 62.1°C - 22.4°C = 39.7°C

c = 0.727 J/g°C

Using Q = m × c × ∆T

Q = 12.3 × 0.727 × 39.7

Q = 355.001

Q = 355Joules

Hence, 355J of heat was absorbed

B.

Explanation:

According to kinetic molecular theory, gas molecules are moving around very rapidly in random directions; they do not line up next to each other like a solid.

Answer:  (1 Kilogram = 2.20462 pounds) . There are 2.2046226218 lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2.205 for an approximate result. 1 kilogram is also equal to 2 lb and 3.27396195 oz. Working out a rough estimate in your head for converting to pounds and ounces may be tricky - remember that there are 16 ounces in a pound.

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Answer:

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Explanation:

If all of the light colored trees disappeared and there are only dark colored ones, then that means that the light colored moths wouldn't be able to live long since their traits wouldn't match the environment. This then leads to the conclusion that dark moths would be better hidden since their trait fits their current environment and would let them be hid much better from predators. This would allow them to survive longer and eventually, reproduce.
