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

Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2

True or False Gases do have a definite shape and volume.
Answer:
false
Explanation:
Answer:
False
Explanation:
It is false as the particles of gases keep moving. They have very weak molecular bonds. They are so weak that they can move freely anywhere and in any direction. Even if you trap some gases and a closed bottle, they keep moving. We can't measure what the shape is or what the volume is. Therefore, it is false.

Tendency of an object to float
Answer:
Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.

Explain how Earth is heated through radiation
Answer:
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Calcium nitrate and calcium carbonate are both ionic compounds.
Calcium nitrate mixed with water behaves as an electrolyte.
Calcium carbonate mixed with water does not behave as an electrolyte.
Explain, in terms of solubility and movement of ions, this difference in behaviour
Answer:
Calcium nitrate is soluble in water and dissociate into ions whereas calcium carbonate is insoluble and water and do not form ions.
Explanation:
An electrolyte is a substance which conducts electricity in molten form or when dissolved in water.
The ability of an electrolyte to conduct electricity is due the movement of charged particles called ions. The ions are of two types: negatively charged ions called anions and positively charged ions called cations.
Calcium nitrate is a soluble in water, and when dissolved in water produces two ions; negatively charged nitrate ions,NO₃⁻, and positively charged calcium ions, Ca²⁺. These ions enable it to conduct electricity.
Calcium carbonate on the other hand is insoluble in water, and thus, do not produces any ions capable of carrying current.
Could cellular respiration
happen without photosynthesis? Explain your
reasoning
Answer:
No
Explanation:
Without photosynthesis, there would be no sugar, without which there could be no cellular respiration.Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.

Which is composed of aromatic hydrocarbons?
clothing

Pain relievers are composed of aromatic hydrocarbons. Therefore, option C is correct.
What are aromatic hydrocarbons ?Hydrocarbons with delocalized pi electrons and sigma bonds between their carbon atoms are known as aromatic hydrocarbons. One example is benzene. Since they smell, they are said to as aromatic.
One aromatic ring makes up monocyclic aromatic hydrocarbons (MAHs). The well-known environmental contaminants benzene, toluene, ethylbenzene, and xylenes are among the most combustible and water-soluble aromatic hydrocarbons (BTEX).
The typical aromatic parent structure is benzene. When the benzene ring is a substituent, it is referred to as a phenyl group.
Thus, Pain relievers are make up of aromatic hydrocarbons, option C is correct.

4 Identify What are the starting materials
and products of photosynthesis and cellular
respiration?
Answer:
Detail is given below.
Explanation:
Photosynthesis:
Reactants = Carbon dioxide + water + energy
Products = glucose + oxygen
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
Reactants = Glucose + oxygen
Products = carbon dioxide + water + 38ATP
Chemical equation:
Glucose + oxygen → carbon dioxide + water + 38ATP
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
