Answer:

No region is safe from flooding. All 50 states are subject to flash floods.[1]

Flash floods can bring walls of water from 10 to 20 feet high.[2]

A car can be taken away in as little as 2 feet of water.[3]

To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[4]

Flooding is caused by spring thawing (snow and frozen grounds melting in the spring), heavy rains, snow melt runoffs, flash floods, and mudflows.[5]

Floods are the most widespread natural disaster aside from wildfires. 90% of all U.S. natural disasters declared by the President involve some sort of flooding.[6]

In preparation for a flood, it is important to stock up on first aid items, non-perishable foods, 3 gallons of water per person for 3 days, battery operated radio for weather reports, extra batteries, personal hygiene necessities.[7]

Based on Floodsmart, a 2,000 square foot home undergoing 12” of water damage could cost more than $50,000.[8]

Since flood damage is almost never covered by homeowners insurance, flood insurance is important for people living in high-risk flood zones.[9]

To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[10]

Communities particularly at risk are those located in low-lying areas, near water, or downstream from a dam.[11]

Answer:

Clastic sedimentary rocks are formed from rock fragments or clasts; chemical sedimentary rocks precipitate from fluids, and biochemical sedimentary rocks form as precipitation from living organisms.

Sedimentary rock is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together. Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

According to ideal gas equation, there are 271472.7 moles of gas present in a gas trapped within a 37.0 L vessel at 80.0°C at a pressure of 2.50 atm.

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

Substitution of values in ideal gas equation gives,n= 2.5×37/8.314×353=271472.7 moles.

Answer:

C: 1 mol F2/38 g F2

Explanation:

The reaction equation is;

N2 + 3F2 = 2NF3

Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;

105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2

Option C is Thus correct

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.

Answer: Hence, the approximate molecular weight of the poymer is 64106 g/mol

Explanation:

[tex]\pi=CRT[/tex]

where,

[tex]\pi[/tex] = osmotic pressure of the solution = 2.012 mm Hg =  0.0026 atm

i = Van't hoff factor = 1 (for non-electrolytes)

Mass of solute (polypeptide) = 1.8274 g  

Volume of solution = 274 mL

R = Gas constant = [tex]0.0821Latm/Kmol[/tex]

T = temperature of the solution = [tex]31.40^0C=(273+31.40)K=304.4K[/tex]

Putting values in above equation, we get:

[tex]0.0026=\frac{1.8274 g\times 1000}{M\times 274ml}\times 0.0821\times 304.4[/tex]

[tex]M=64106g/mol[/tex]

Hence, the approximate molecular weight of the poymer is 64106 g/mol

Answer:

B. Molarity will decrease

Explanation:

Molarity is one of the measures of the molar concentration of a solution. It is calculated by dividing the number of moles of the solute by the volume of the solvent. This means that the higher the amount of solute in relation to the volume of solvent, the higher the molarity of that solution.

In essence, adding water to a solution dilutes it i.e it increases the solvent's volume in relation to the solute, causing the molarity to decrease. In a nutshell, diluting a solution (by adding water or more solvent) causes the molarity of such solution to decrease. For example, if water is added to a 0.70 molar solution of CuSO4, the molarity of the solution will DECREASE.

Answer: [tex]S[/tex] is the limiting reagent

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} S=\frac{10.0g}{32g/mol}=0.3125moles[/tex]

[tex]\text{Moles of} Ag=0.700moles[/tex]

[tex]2Ag+S\rightarrow Ag_2S[/tex]  

According to stoichiometry :

1 mole of [tex]S[/tex] require = 2 moles of [tex]Ag[/tex]  

Thus 0.3125 moles of [tex]S[/tex] will require=[tex]\frac{2}{1}\times 0.3125=0.6250moles[/tex]  of [tex]Ag[/tex]

Thus [tex]S[/tex] is the limiting reagent as it limits the formation of product and [tex]Ag[/tex] is the excess reagent.
