Answer:

8,5 E10 nm

Explanation:

⇒ 0.85 E-2 Km * ( 1000 m / Km ) * ( 1 E9 nm / m ) = 8.5 E10 nm

⇒ 0.85 E-2 Km = 8.5 E10 nm

Answer : The $0.85\times 10^{-12}km$ is equal to 0.85 nm.

Explanation :

The conversion used from kilometer (km) to nanometer (nm) is:

$1km=10^{12}nm$

As we are given that the distance $0.85\times 10^{-12}km$ . Now we have to calculate the distance in 'nm'.

As, $1km=10^{12}nm$

So, $0.85\times 10^{-12}km=\frac{0.85\times 10^{-12}km}{1km}\times 10^{12}nm=0.85nm$

Therefore, the $0.85\times 10^{-12}km$ is equal to 0.85 nm.

Consider the following reaction at 298 K:

faltersainse [42]

Answer :

$\Delta S_{sys}$ = -1622.8 J/K

$\Delta S_{surr}$ = -94.6 J/K

$\Delta S_{univ}$ = 0 J/K

Explanation : Given,

$\Delta H$ = -483.6 kJ

The given chemical reaction is:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(g)$

First we have to calculate the value of $\Delta S_{sys}$ .

$\Delta S_{sys}=\frac{\Delta H}{T}$

$\Delta S_{sys}=\frac{-483.6kJ}{298K}$

$\Delta S_{sys}=-1.6228kJ/K=-1622.8J/K$

Entropy of system = -1622.8 J/K

As we know that:

Entropy of system = -Entropy of surrounding = 1622.8 J/K

and,

Entropy of universe = Entropy of system + Entropy of surrounding

Entropy of universe = -1622.8 J/K + (1622.8 J/K)

Entropy of universe = 0

1.Build or draw the Lewis structure for each of the molecules listed below.

This may help you

Allright for H2O: - The central atom is? --> the oxygen atom - How many atoms are bonded to the central atom? --> 2 hydrogen atoms - How many lone pairs of electrons are on the central atom? --> O has 6 electrons and has 2 single bonds, so 2 pairs - How many single bonds are there in this molecule? --> 2 - How many multiple bonds (double and/or triple) are there in this molecule? --> none For each of your molecules, answer the following questions: 1. Determine the electronegativity between the atoms of each molecule. Electronegativity O = 3.44 Electronegativity H = 2.20 3.44-2.20=1.24, so the electronegativity between O and H = 1.24 2. Identify the bond as either ionic or covalent. Electronegativity of 0.0-1.7 = covalent Electronegativity of 1.7-3.3 = ionic So it's a covalent bond 3. State whether the molecule is polar or non polar. Electronegativity of 0.5-1.7= polar covalent 4. Identify the structure as having hydrogen bonding, dipole-dipole moments or London dispersion forces (LDF). H2O = hydrogen bonding

What is the concentration, in m/v percent, of a solution prepared from 50 g NaCl and 2.5 L of solution?

Serjik [45]

When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.

Given that blood exerts the same osmotic pressure as a 0.15 M NaCl solution, which solution could be the hypertonic solution?/se

inna [77]

Answer:

a. 0.68 M NaCl solution

Explanation:

The tonicity of a solution can either be hypotonic, hypertonic and isotonic. Hypertonic solution is a solution which possesses a higher concentration of solute in relation to another solution.

According to this question, a solution is said to contain 0.15 M NaCl solute. This means that a solution that will be hypertonic to this solution will have a much more concentration of solute, which based on the options provided is the 0.68 M NaCl solution.
