Answer:
The pH of a solution with the [H + ] = 1 × 10 -2 M is 2 and the pH of a solution with the [H + ] = 1 × 10 -10 M is 10. ( I think this is correct ).
Explanation:
The question is incomplete, the complete question is;
Which of the following aspects of biotechnology is Not considered to be a moral or ethical issue?
a.research and testing on animals
b.cloning living material
c.reducing research cost
d.damaging the environment
Answer:
c.reducing research cost
Explanation:
Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.
Research and testing on animals is contested as an ethical issue by animal rights activists.
Cloning living material is prohibited among some sections of society and is also being contested as an ethical issue.
Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.
However, reducing research cost is highly acceptable in any research. It does not pose an ethical issue.
Answer:
Protein
Explanation:
Cholesterol is actually part lipid, part protein
Answer:
T = 561.3K
Explanation:
The translational kinetic energy of a gas such as nitrogen is obtained using the formula:
K = 3/2 * n * R * T
<em>Where n are moles of gases (1mole of N₂), R is gas constant (8.314J/molK)and T is absolute temperature (in K)</em>
If the translational energy of the gas is 7.0x10³J:
7.0x10³J = 3/2 * 1 mole * 8.314J/molK * T
<h3>T = 561.3K</h3>
The correct answer is 6.15g of CO2 will be produced.
The approach to answer this question is to use the molar mass to find the number of moles of oxygen consumed. Then use the chemical equation to determine the number of moles of CO2 that would be produced (half that of oxygen). Then use the molar mass of CO2 to calculate the mass.
Mmass O2 = 32g/mol
Mmass CO2 = 44.01g/mol
mass O2 consumed = 8.94g
mass CO2 produced = ?
moles O2 = mass / molar mass = 8.94 / 32 = 0.279
moles CO2 = half that of O2 = 0.1397
mass CO2 produced = moles CO2 x molar mass = 0.1397 x 44.01 = 6.15 g
