How many moles Of H2O will be produced from 42.0 g of H2O2?
d1i1m1o1n [39]
Molar{Mass} H_{2}O_{2} =2*16.0+2*1.0= 34.0 g/mol

42.0 g H_{2}O_{2}* \frac{1 mol H_{2}O_{2}}{34.0 g H_{2}O_{2}} = 1.24 mol H_{2}O_{2}

2H_{2}O_{2} --\ \textgreater \ 2 H_{2}O +O_{2}
\\2 mol  ----2 mol   (from// reaction)

\\1.24 mol ---1.24 mol (from  the problem)

Answer: 1.24 mol H_{2}O.

The alkane with six carbon atoms is called hexane. butane. butene. heptane. none of these choices is correct.
Mkey [24]

Option(A) is the correct answer.

The alkane with six carbons is called hexane.

<h3>What are the potential hazards of hexane?</h3>

Hexane is used as a special-purpose solvent, a cleaning agent, and to extract edible oils from seeds and vegetables. Humans who are acutely (short-term) inhaled high quantities of hexane have moderate central nervous system (CNS) symptoms such giddiness, nausea, headache, and dizziness. Humans who are exposed to hexane in the air <u>over an extended period of time</u> may develop polyneuropathy, which manifests as numbness in the extremities, muscle weakness, impaired vision, headaches, and tiredness. Rats have also displayed neurotoxic consequences. Hexane's potential to cause cancer in both humans and animals is unknown. Hexane has been categorized by the EPA as Group D, not classifiable as a human carcinogen.

Answer:

1. Density of the rectangular prism is  <u>20 g/cm3</u>

2. A material's ability to dissolve : <u>Soubility</u>

3. <u>Intensive property</u> : A physical property that is independent of sample size.

Explanation:

Volume of Prism is calculated by :

volume = L\times W\times H

Length = 3 cm

Width = 2 cm

Height = 1 cm

volume = 3\times 2\times 1

V = 6 cm3

mass = 120 g

Density = \frac{mass}{Volume}

Density = \frac{120}{6}

Density = 20 g/cm3

2.

<u>Solubility :</u>

  • It is the chemical property of the substance.
  • It shows the ability of the solute to dissolve in the solvent at a given temperature.

3.

<u>Intensive Properties:</u>

  • These are bulk properties(Do not depend upon the amount of matter present)
  • They are independent of sample size.
  • Example : boiling point,melting point,temperature,refractive index

A metal weighing 7.101 g is placed in a graduated cylinder containing 33.0 mL of water. The water level rose to the 37.4 mL mark
musickatia [10]
Volume of the metal = change in volume reading
Volume = 37.4 - 33
Volume = 4.4 ml

Density = mass / volume
Density = 7.101 / 4.4
Density = 1.61 g/ml
