Answer: $46.98

Explanation:

The distance to drive to Los Angeles from San Francisco is 405 miles. Since the car get 25 miles per gallon of gas, for 405 miles, the car will use:

= 405/25 = 16.2 gallons

Since the cost of gasoline is $2.90 a gallon and the car will use 16.2 gallons. The cost will be:

= $2.90 × 16.2 gallons

= $46.98

The density is the ratio of the mass to the volume. The density of the object is 44.1 g/cm³.

Density (ρ) is the quantitative measurement of the substance having grams of mass that are dissolved per cubic meter of the solution. The density is calculated as:

ρ = M ÷ V

Given,

Mass of the object = 441 gm

The volume of the object = 10 cubic meter

Density is calculated as:

ρ = 441 ÷ 10

= 44.1 g/cm³

Therefore, 44.1 g/cm³ is the density of the object.

Answer:

2 circles one proton and one nucleon.draw quarks within each. strong nuclear force within protons between quarks and residual strong force between proton and nucleon (up,up,down in proton)

Explanation:

Answer:

2

Explanation:

From this equation, 2 grams are produced.

The mass of H₂O produced from the reaction is 2.25 g

We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.

N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O

Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol

Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

32 g of N₂H₄ reacted to produce 36 g of H₂O.

From the balanced equation above,

, 32 g of N₂H₄ reacted to produce 36 g of H₂O.

Therefore,

2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O

Thus, the mass of H₂O produced from the reaction is 2.25 g

Answer: E

Explanation:

Answer:

D

Explanation:

When you mix a strong acid and a strong base : ( D ) You will wind up with a pH-neutral salt and water

The mixture of a strong base and an equally strong acid results in a neutralization reaction, because at the point of equivalence the base and acid will completely neutralize each other.

The mixture solution will have a pH value of 7 and the end products will an ionic salt and water.

Hence we can conclude that When you mix a strong acid and a strong base , you will wind up with a pH-neutral salt and water.

Answer: well i guess we can say that  is a scale used to specify the acidity or basicity of an aqueous solution and it is important to keep ph of hot tub water between 7 and 7.6 because if it is not balanced the water  can negatively affect your tub.

Explanation:

pH is an extremely important chemical level to maintain in your spa's water chemistry. A high pH or a low pH will spell trouble for you and your spa. On the pH scale, a reading of 7.4-7.6 indicates perfectly balanced pH. Any number lower than 7.4 means that your water is now considered “acidic”.

Answer:

pH is a scale to measure the acidity or basicity of a substance such as water, it would be important to keep the pH of hot-tub water between 7 and 7.6 because if the acidity is too high, the walls of the hot-tub may be damaged, and if the pH is too low, the heating thing may get damaged.
