How do atmospheric updrafts affect clouds?
Answer:
Updrafts characterize a storm's early development, during which warm air rises to the level where condensation begins and precipitation starts to develop. In a mature storm, updrafts are present alongside downdrafts caused by cooling and by falling precipitation.

Suppose you have 6 miles of ethanol(C2H6O)to combust.How many moles of oxygen will the combustion use?
Answer: 18 moles of oxygen will be used.
Explanation:
Combustion is a chemical reaction in which a hydrocarbon is oxidized in the presence of oxygen to give carbon dioxide and water.
The balanced chemical reaction for combustion of ethanol is:
[tex]C_2H_6O+3O_2\rightarrow 2CO_2+3H_2O[/tex]
According to stoichiometry :
1 mole of ethanol require = 3 moles of [tex]O_2[/tex]
Thus 6 moles of ethanol will require=[tex]\frac{3}{1}\times 6=18moles[/tex] of [tex]O_2[/tex]
Thus 18 moles of oxygen will be used.
Where on the pH scale would you find acids? Bases? What is unique about a pH of 7?
Answer:
Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.
Explanation:
Answer:
7 is neutral, acids are 1-6, bases are 8-14. Pure water has a pH of 7, where as almost everything else is either an acid or a base.

NaOH
HCl
NaCl
H2O
Answer:
NaOH
Explanation:
Sodium hydroxide is the base in the acid-base reaction as all other acids and sodium chloride is salt and water is neutral.
What is a base?According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.
Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.
They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

would the pressure exerted by the gas in the tank would increase if the scuba tank were to increase in temperature?
Answer:
In fact, a full scuba tank will gain about 5-6 psi for every degree of temperature increase. This is one reason that full tanks should not be left in a hot trunk of a car. A tank filled to 3000 psi could easily reach 3500 psi if the temperature of it increased substantially.

Higher classification: Hexapoda
Dose hexane have charged regions?
Answer:
Hexane will not have any dipole-dipole interactions because it is a non-polar molecule
Explanation:
Explanation:
This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges. Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces.

If an unknow metal has the mass of 40g and volume of 75ml, what is the density of the metal?
Answer:
d = 0.53 g/mL
Explanation:
Given that,
Mass of an unknown metal = 40 g
The volume of the metal = 75 mL
We need to find the density of the metal. We know that,
Density = mass/ volume
[tex]d=\dfrac{40\ g}{75\ mL}\\\\d=0.53\ g/mL[/tex]
So, the density of the metal is 0.53 g/mL.
When NH4SCN is added to a solution of Fe3+ ions, the solution changes from yellow to orange. What is the best explanation for this color change?
Answer:
The iron present in the solution is reduced because of the presence of SCN⁻ ions in solution
Explanation:
The clue in this problem is the color of the solution:
A solution of Fe³⁻ is yellow but when the Fe³⁺ is reduced by an oxidant to Fe²⁺ the solution change to orange color.
The SCN⁻ ion is a reducing agent than, in presence of a substance that can be reducted as Fe³⁺ ion will promote the reaction. That means the best explanation is:
The iron present in the solution is reduced because of the presence of SCN⁻ ions in solutionWhat organelle is sac like and stores different materials?

¿Cuántos gramos de dicloruro de manganeso se obtienen cuando reaccionan 7,5 g de ácido clorhídrico? MnO2 + 4 HCl = Mn Cl2 + Cl2 + 2 H2O *
Answer:
6.6 g
Explanation:
La ecuación de la reacción es;
MnO2 + 4 HCl -------> MnCl2 + Cl2 + 2H2O
Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles
Dado que;
4 moles de HCl producen 1 mol de MnCl2
0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.
Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g
9.32 L of pentane reacts with 36.4 L of oxygen. how many liters of carbon dioxide are formed?
Answer:
22.75 L CO2
Explanation:
Balance the Equation
C5H12 + O2 ==> CO2 + H2O Balance the Carbons
C5H12 + O2 ==> 5CO2 + H2O Now balance the Hydrogens
C5H12 + O2 ==> 5CO2 + 6H2O Now count up the oxygens on the right.
5*O2 + 6O ==> 10 O + 6 O ===> 16 Oxygens.
You have 2 on the left. You have to multiply the oxygens by 8
C5H12 + 8O2 ==> 5CO2 + 6 H2O
The equation is now balanced.
Now find out how much oxygen is needed to burn 9.32 L of Pentane
1 Liter Pentane / 8 Liters Oxygen = 9.32 L Pentane / x Cross multiply
x = 8 * 9.32
x = 74.56
Read this next sentence very carefully. You need 74.56 Liters of oxygen to burn all the pentane you have. There's not that much there. You only have 36.4 Liters of Oxygen. Some of the pentane won't get burned. Consequently there will be a shortage of CO2 as well.
Find out the number of Liters of Pentane that will be burned up.
1 / x = 8 / 36.4 Cross multiply
8x = 36.4 Divide by 8
8x/8 = 36.4/8
x = 4.55 Liters of Pentane will be used up.
Find the number of Liters of CO2
For every Liter of Pentane, 5 Liters of CO2 will be produced.
1/5 = 4.55/x Cross Multiply
x = 5 * 4.55
x = 22.75
A gas has a volume of 240.0mL at 25.0 oC and 0.79 atm. Calculate its volume at STP (1 atm and 0 oC).
Answer:
189.6 mL
Explanation:
As per Boyles law when a gas is kept at a constant temperature and mass in a closed container, the volume and pressure vary inversely.
P1V1= P2V2
Here, P1 = 0.79 atm, V1 = 240 ml, P2= 1 atm
therefore, substituting values in above equation we get
0.79×240 = 1×V2
⇒V2 = 189.6 ml
therefore, its volume at STP (1 atm and 0 oC) = 189.6 ml
