Answer:

Explanation:  Hydrochloric Acid (HCl) Hydrochloric acid is the strong acid which is found inside our body in the gastric juice. It helps in the breakdown of all the potatoes and pizzas we eat and turns down the enzymes, which change the food particles into protein.LSD is made by creating a fungus on seeds of rye or morning glory. A hallucinogenic drug, capable of changing the way people look at, think about, and experience the world around them. The power of this drug makes it popular, as does its portability.

An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.

The word acid comes from the Latin words acidus or acere, which mean "sour," since one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).

A graduated cylinder contains 10.00 mL water. A 14.74 g piece of aluminum is added to the water, and the volume rises to 15.46 m
Lyrx [107]

Answer:

2.67 g/mL

Explanation:

Initial Volume of water = 10.0 mL

Final Volume pf water = 15.46 mL

Mass = 14.74g

Density = Mass / Volume of aluminium

Volume of aluminium = Final Volume of water - Initial Volume of water = 15.46 - 10 = 5.46mL

Density = 14.74 / 5.46 = 2.67 g/mL

A liquid sample, with a density of .0915 g/mL has a mass of 17.7 grams.
Arlecino [84]

The relation between density, mass and volume is

Density = \frac{Mass}{Volume}

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

Density = \frac{Mass}{Volume}

Thus

Volume Volume = \frac{Mass}{Density} = \frac{17.7 g}{0.915 \frac{g}{mL} }  = 193.44 mL

Answer: 193.44 mL

2) the mass of sample will be

mass = density X volume = 0.0915\frac{g}{mL} X 76.5 mL = 6.99 = 7 g

Answer: 7 g
