What is an example of a microorganism acting in a harmful way? A) Bacteria aiding digestion. B) Bacteria causing strep throat. C
vaieri [72.5K]
Not very often, but sometimes, the language gives away the question. This is one such instance.

Look at A. Is digestion a bad thing? It shouldn't be. Otherwise you run marathons with gobs of food not being broken down and providing energy. 
Not A.

Not C. Do you like yogurt? If you don't do you know someone who does? Is yogurt for you/them a bad thing. Bacteria here are good. Again, not C.

Not D. Waste is bad. It's a problem. Getting rid of it is good. Again not D.

There's only one left.
B <<<< answer. Who would like to get strep throat. It's a fate for your worst enemy.

B <<<< answer.

What is the S.I unit of torque?
lora16 [44]
Torque has the dimension of force times distance, symbolically L2MT−2. Official SI literature suggests using the unit newton metre (N⋅m), or, joule per radian (J/rad). The unit newton metre is properly denoted N⋅m rather than m.

Calculate the vapor pressure of water above a solution prepared by dissolving 28.5 g of glycerin (c3h8o3) in 135 g of water at 3
pshichka [43]
Data:

<span>Solute: 28.5 g of glycerin (C3H8O3)
Solvent: 135 g of water at 343 k.
Vapor pressure of water at 343 k: 233.7 torr.

Quesiton: Vapor pressure of water

Solution:

Raoult's Law: </span><span><span>The vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature  multiplied by its mole fraction.

Formula: p = Xsolvent * P pure solvent

X solvent = moles solvent / moles of solution

molar mass of H2O = 2*1.0g/mol + 16.0 g/mol = 18.0 g/mol

moles of solvent = 135 g of water / 18.0 g/mol = 7.50 mol

molar mass of C3H8O3 = 3*12.0 g/mol + 8*1 g/mol + 3*16g/mol = 92 g/mol

moles of solute = 28.5 g / 92.0 g/mol = 0.310 mol

moles of solution = moles of solute + moles of solvent = 7.50mol + 0.310mol = 7.810 mol

Xsolvent = 7.50mol / 7.81mol = 0.960

p = 233.7 torr * 0.960 = 224.4 torr

Answer: 224.4 torr

Identify What are the charges on ions of Group 1A,<br> Group 3A (aluminum), and Group 5A?
dalvyx [7]

Explanation:

 Group 1A         +1

 Group 3A         +3 or +1

 Group 5A         +5 or +3

The charges on an ion signifies the number of electrons that has been lost, gained or shared by an atom. These electrons are called valence electrons occupying the outermost shell of an atom.

 Group 1A element will readily be willing to lose an electron giving them a charge of +1

  Group 3A can lose either 1 or 3 electrons giving a charge of +3 or +1

  Group 5A can lose either 5 or 3 electrons giving a charge of +5 or +3

The number of lost electron confers the stability on the configuration.
