what is the mass in grams of 0.40 moles of sodium borohydride nabh4
Answer:
15.12g
Explanation:
Given parameters:
Number of moles = 0.4moles
Unknown:
Mass of the compound = ?
Solution:
To solve this problem;
Mass = number of moles x molar mass
Molar mass of NaBH₄ = 23 + 10.8 + 4(1) = 37.8g/mol
Mass of the compound = 0.4 x 37.8 = 15.12g
Answer:
The answer is 15.12 g but if you are taking this test on ck12 make sure you round it to 15 like it says on the directions :) good luck

What is the conversion between atm (standard atmosphere) and mmHg (millimeters of mercury)?
Multiply the atm amount by 760 to get the mmHg amount.
19/25 * 760/1
19/5 * 152/1
(19*152)/5

We can draw three inequivalent Lewis structures for the sulfite ion , SO32- . The concepts of formal charge and electronegativity can help us choose the structure that is the best representation. 1. Assign formal charges to the elements in each of the structures below. Note: Count oxygen atoms starting from the left for each structure. A B C Formal Charge S O1 O2 O3 2. The best Lewis structure for SO32- is
Answer:
1. The Lewis structure for SO32- is structure B.
Note: See attachment for complete question and for formal charges of the atoms in each structure.
Explanation:
The formal charge of an atom in a molecule is the assumed charge the atom would have if the electrons in the bonds were evenly distributed between the atoms.
Formal charge can be calculated as follows:
Formal charge = number of valence electrons - ( number of non-bonding electrons + ½ bonding electrons)
Formal charges are used to determine the best possible Lewis structure of a molecule or ion. The following rules are applied:
1. A structure in which all formal charges are zero is preferable to one in which some formal charges are not zero.
2. If non-zero formal charges must exist in the structure , the arrangement with the smallest non-zero formal charges is most preferred.
3. Lewis structures are preferable when adjacent formal charges are zero or of the opposite sign.
4. The structure with the negative formal charges on the more electronegative atoms is preferred among other structures of the molecule or ion.
From the above rules, structure B has negative charges on the more electronegative oxygen atoms and has more zero formal charges on the atoms. The central atom, sulfur also has a zero formal charge.

. What were the main inventions of the industrial revolution? What changes did they bring about ?
Answer:
The Industrial Revolution was a period of great industrialization that began in the late 18th century in Britain, leading to massive population growth and agricultural innovations, which laid the foundation for increased productivity, both with increased labor and a larger market for the products. There was a revolution in the production methods of the textile industry, especially with the advent of the steam engine and urban development, the influx of people from the countryside to the cities meant that there was an abundance of labor, which laid the foundation for the industrial cities of the nineteenth century. The steam engine was also used in the new generation of transport, in locomotives and steamships. With the advent of steel as a building material along with a series of new discoveries in communication technology in the second half of the 19th century, the tone was set for the continued technological development of the 20th century.

Which chemical used to make explosives is a fertilizer-based explosive, but requires nitric acid as a component to be an explosive compound, and has a wide range of uses, including as a noncorrosive de-icing material for sidewalks?
a. Aluminum nitrate
b. Triacetone triperoxide (TATP)
c. Hexamethylene triperoxide diamine (HMTD)
d. Urea nitrate
Answer:
d. Urea nitrate
Explanation:
Urea nitrate is a fertilizer-based explosive that is produced in one step by reaction of urea with nitric acid. The is an exothermic reaction, therefore, necessary steps and precautions must be taken to ensure safety during the process. The equation of the reaction is given below:
(NH₂)₂CO (aq) + HNO₃ (aq) → (NH₂)₂COHNO₃ (s)
It is as easily-made explosive and can also be used as a catalyst in Diels-Alder reactions of aromatic amines.
In the presence of water, urea nitrate readily decomposes to its original components, urea and nitric acid.
On its own, urea is commonly used as a deicer for sidewalks as it is a noncorrosive de-icing material. However, it is a more costly method of deicing, compared to other methods and it is best used where water runs off into vegetation than into a water-body or a storm drain because of its high-oxygen demand which could result in its reducing the oxygen level of the water body. It It is readily found in nature (in our urine) and is also synthesized artificially. It has a very high nitrogen content, and is most often used as a nitrogen‐based fertilizer.
I need help on these questions!
Answer:
See explanation
Explanation:
Given that;
E = hc/λ
h = 6.63 * 10^-34 Js
c = 3 * 10^8 ms-1
λ = ?
E = 3.978 * 10^-19 J
λ = hc/E
λ = 6.63 * 10^-34 * 3 * 10^8 /3.978 * 10^-19
λ = 19.89 * 10^-26/3.978 * 10^-19
λ = 5 * 10^-7 m The colour is green
2. E = hc/λ
E= 6.63 * 10^-34 * 3 * 10^8 /1000 * 10^-9
E = 1.989 * 10^-19 J
But
E = hf
f = E/h
f = 1.989 * 10^-19/6.63 * 10^-34
f = 3 * 10^14 Hz The radiation is infrared
3. E = hc/λ
λ= hc/E
λ= 6.63 * 10^-34 * 3 * 10^8 /2.0 * 10^-14
λ= 995 * 10^-14 m This is gamma radiation
4. E = hc/λ
E=6.63 * 10^-34 * 3 * 10^8 /620 * 10^-9
E = 3.2 * 10^-19 J
5. E = hf
E= 6.63 * 10^-34 * 2 * 10^17
E = 1326 * 10^-19 J
E = hc/λ
λ= hc/E
λ= 6.63 * 10^-34 * 3 * 10^8 /1326 * 10^-19 = 15 * 10^-9
This is ultraviolet radiation
How many grams of Fe3+ are present in 2.56 grams of iron(III) iodide?
Answer:
436.55841 grams.
Explanation:
The molecular formula for Iron(III) Iodide is FeI3. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Iron(III) Iodide, or 436.55841 grams.
You use the 1 / 436.55841 conversion rate. This is different for each element, according to the stoichiometry tables. Iron(II) oxide would be 2/3 of the 1/436.55841 conversion rate, that is, multiplying the fraction to denominator.
Sulfur dioxide, SO2, is used in wine as an antioxidant, slowing the oxidation of ethanol
to ethanoic acid. To determine the SO2 content of a wine sample, sodium hydroxide
and sulfuric acid were added to ensure that all sulfur was present as SO2. A 20.00 mL
aliquot was then titrated against standardised iodine solution, using starch indicator.
Reaction occurred according to the equation:
SO2(aq) + 2H2O(l) + 12(aq) → 4H+ (aq) + 21- (aq) + SO42- (aq)
The end point was reached with 15.62 mL of 0.00501 M iodine solution. The
concentration (in M) of SO2 in the wine was ...
A)6.2 x 10-3
B)7.8 x 10-3
C)3.9 x 10-3
D)5.0 x 10-3
The concentration (in M) of SO₂ in the wine : c. 3.9 x 10⁻³
Further explanationGiven
Reaction
SO2(aq) + 2H2O(l) + I2(aq) → 4H+ (aq) + 21- (aq) + SO42- (aq)
Required
The concentration (in M) of SO2
Solution
Titration ⇒ mol SO₂ = mol iodine(I)
mol iodine :
=15.62 ml x 0.00501 M
=0.078256 mlmol
From equation, mol ratio of of SO₂ : I₂ = 1 : 1, so mol SO₂=0.078256
The concentration of SO₂(in 20 ml sample) :
M = n/V
M = 0.078256 mlmol/20 ml
M = 0.0039128
M = 3.9 x 10⁻³

Which best describes why NH4+ can form an ionic bond with Cl–?
Its outermost shell gains one or more electrons from Cl–.
Its positive charge is attracted to the negative charge of Cl–.
It has a negative charge that is spread over the entire ion.
It has a nitrogen atom that is strongly attracted to Cl–.
Answer:
Its positive charge is attracted to the negative charge of Cl–.
Explanation:
The best description of why NH₄⁺ forms an ionic bond with Cl⁻ is that its positive charge is attracted to the negative charge of Cl⁻.
An ionic bond forms as a result of transfer of electrons. As a result the seemingly metal ion is attracted to the negative non-metal ion.
The electrostatic force of attraction between these ions is the ionic or electrovalent bond.
So, the attraction between these opposite charges will form the ionic bond.
Answer:
B: Its positive charge is attracted to the negative charge of Cl–

R = gas constant = 0.0821 L.atm / mol.K
Δn=moles products - moles reactants or

number of product coefficients = 1+1=2
number of reactant coefficients = 1
Δn= 2 - 1 =1
So Kp/Kc = RT
What is the only way to be certain that a chemical change has occurred
Answer:
New kinds of products forms and the reaction is not easily reversible.
Explanation:
The only way to be certain that a chemical change has occurred is by finding out if new kinds of products have been formed.
A chemical change is a change in which new kinds of matter is formed. It is always accompanied by energy changes.
The process is not easily reversible.
Examples of chemical changes are combustion, rusting of iron, precipitation and souring of milk.
