Explanation:

The total distance Jimmy traveled would be the sum of the distance covered from his house to the store and then from the store to his friend's house. The total distance covered can be determined if the average speed of Jimmy and the time he took to cover the distance are known.

    Average speed = total distance traveled/total time taken

Hence,

total distance traveled = average speed x total time.

Answer:

Surface water and groundwater systems are connected in most landscapes. ... It is the groundwater contribution that keeps streams flowing between precipitation events or after snowmelt. For a stream to gain water, the elevation of the water table in the vicinity of the stream must be higher than the streamwater surface.

Answer:

120g

Explanation:

Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.

Thus, we need to convert mass of water to moles using its molar mass:

Moles H2O (Molar mass: 18g/mol):

63g H2O * (1mol / 18g) = 3.5 moles H2O

Converting to moles of CO2:

3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2

Mass CO2 (Molar mass: 44g/mol):

2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

Giraffes eat new shoots and leaves, their habitat needs to have a good supply of trees -- they flock towards acacia trees in particular. Giraffes use their extremely long legs, necks and tongues to browse mainly from the thorns on the acacia tree. The tongue and the inside of the mouth are lined with tough tissue that protects against the thorns.

Answer:

D) All of the above

Explanation:

When the temperature of an object increases, the average kinetic energy and speed of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object also increases as its temperature increases.

Explanation:

water is a liquid if you can't see

moles Cu produced : 0.002

Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³

MW CuSO₄ :

[tex]\tt =63.5+32+4\times 16=159.5~g/mol[/tex]

mol CuSO₄ /dm³ :

[tex]\tt \dfrac{0.319}{159.5}=0.002[/tex]

CuSO₄⇒Cu²⁺ + SO₄²⁻

mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002

Answer:

The density of the unknown substance is 0.75 g/mL.

Explanation:

We are given the volume and mass of a substance and are asked to find the density.

Density is determined with the formula [tex]d=\frac{m}{v}[/tex], where d is the density, m is the mass of the substance, and v is the volume the substance occupies.

Therefore, the density can be found by dividing the mass and volume.

We are given and can determine that:

Now, let's set up the math required.

[tex]d = \frac{90 \ \text{grams}}{120 \ \text{mL}}\\\\d = \frac{3 \ \text{grams}}{4 \ \text{mL}}\\\\d = \frac{3}{4} \ \text{grams per mL}\\\\d = \frac{3}{4} \ \text{g/mL}\\\\ \bold{d = 0.75 \ \bold{g/mL}}[/tex]

Therefore, the density of the substance is 0.75 g/mL.

1, 3, 1, 3

Explanation:

Ga - one on both sides

F - three on both sides

CN - three on both sides

K - three on both sides

But remember that CN was being multiplied by 3 on the right side already, meaning GA(CN)3 didn't mean a coefficient.

Answer:

Double re-placement

The two metals switched dance partners, that means it's a double.

Answer: Nitrogen

Explanation:

Answer:

To answer the question, we correctly fill the attached screenshot as follows;

[tex]100.0 g \ H_2 \times \dfrac{1 \ mol \ H_2}{2 \ g \ H_2} \times \dfrac{2 \ mol \ NH_3}{3 \ mol \ H_2} = 33.\bar 3 \ mol \ NH_3[/tex]

The molar mass of N₂ = 28 g/mol

[tex]100.0 g \ N_2 \times \dfrac{1 \ mol \ N_2}{28 \ g \ N_2} \times \dfrac{2 \ mol \ NH_3}{1 \ mol \ N_2} \approx 7.143 \ mol \ NH_3[/tex]

A. Therefore, the excess reactant is hydrogen gas H₂ because it makes the most amount of ammonia, NH₃ (33.[tex]\bar 3[/tex] moles of NH₃)

B. The limiting reactant in nitrogen, N₂, because it is the reactant that makes the least amount of the ammonia, NH₃ (approximately 7.143 mol NH₃)

C. The theoretical yield of ammonia, is the maximum amount of ammonium that can be produced from the reaction between the 100 g of hydrogen gas, H₂, and 100 g of nitrogen gas, N₂ which is given by the amount of ammonia produced by the limiting reactant which is approximately 7.143 mole of NH₃

Answer:

In the human body, potential energy is stored in the bonds between atoms and molecules. Chemical energy is the form of potential energy in which energy is stored in chemical bonds. When those bonds are formed, chemical energy is invested, and when they break, chemical energy is released. Notice that chemical energy, like all energy, is neither created nor destroyed; rather, it is converted from one form to another. When you eat an energy bar before heading out the door for a hike, the honey, nuts, and other foods the bar contains are broken down and rearranged by your body into molecules that your muscle cells convert to kinetic energy.

Answer:

it is endothermic change ..........

Answer:

Endothermic change

Explanation:

Khan Academy:

"The reactants are at a lower energy level compared to the products—as shown in the energy diagram. Since we are forcing the reaction in the forward direction towards more unstable entities, overall ΔH for the reaction is positive, i.e., energy is absorbed from the surroundings."

- The answer is from a khan academy lesson.
