Excess hydrogen in the body through carbonic acid is known to affect blood. In the blood we have hemoglobin which is a red blood cell protein that allows red blood cells to carry oxygen but when hydrogen is introduced in the blood, of causes some of the hemoglobin to release oxygen, causing oxygen deprivation in major organs. Even 1 minute of oxygen deprivation can cause severe damage to the brain, liver, kidneys, heart, stomach, and every other major organ.

A student calculates that the volume of his textbook is 991.880 cm3. what is the volume written with 3 significant figures?
k0ka [10]

The volume of the textbook calculated by the student written to 3 significant figures is 992cm³

  • According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.

  • To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.

  • To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.

What is the density of a sample of a substance with a volume of 120ml<br> and a mass of 90g?
tigry1 [53]

Answer:

<h3>The answer is 0.75 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 90 g

volume = 120 mL

We have

density =  \frac{90}{120}  =  \frac{9}{12}  =  \frac{3}{4}  \\

We have the final answer as

<h3>0.75 g/mL</h3>

Hope this helps you

A gaseous fuel mixture stored at 747 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 11.1 L of this fuel mix
Alisiya [41]

Answer:

M_f=38.8\%

Explanation:

From the question we are told that:

Pressure P=747mmHg

Temperature T=298K

Volume V=11.1

Heat Produced Q=780kJ

Generally the equation for ideal gas is mathematically given by

 PV=nRT

 n= (747/760) *11.1/ (0.0821*298)

 n=0.446mol

Therefore

 x+y=0.446

 x=0.446-y .....1

Since

Heat of combustion of Methane=889 kJ/mol

Heat of combustion of Propane=2220 kJ/mol

Therefore

 x(889) + y(2220) = 760 ...... 2

Comparing Equation 1 and 2 and solving simultaneously

 x=0.446-y .....1

 x(889) + y(2220) = 760 ...... 2

 x=0.173

 y=0.273

Therefore

Mole fraction 0f Methane is mathematically given as

 M_f=\frac{x}{n}*100\%

 M_f=\frac{1.173}{0.446}*100\%

 M_f=38.8\%
