Flow-duration data are daily mean flow values measured over a specified time interval that have been exceeded various percentages of the specified time interval.

Water is a very flexible material. It can flow in many different directions and shapes. This flexibility makes it great for many different purposes, such as drinking, washing, and irrigation. Water is considered to be a flexible substance because it can change its shape according to space.

Water is a liquid at standard temperature and pressure (25 degrees Celsius and 1 atm, for liquids).

Water is is tasteless and odorless.

Water is transparent in the visible part of the electromagnetic spectrum.

Water can act as either an acid or a base.

Water is a universal solvent, dissolving many substances found in nature.

Water is the most abundant compound on Earth’s surface. In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature (approximately 25 degrees Celsius), it is a tasteless, odorless, and colorless liquid. Many substances dissolve in water, and it is commonly referred to as the universal solvent.

Therefore, Water is a very flexible material. It can flow in many different directions and shapes. This flexibility makes it great for many different purposes, such as drinking, washing, and irrigation. Water is considered to be a flexible substance because it can change its shape according to space.

Answer:

Charle's Law ... V ∝ f(T); Pressure and Mass remain constant

Explanation:

Charle's Law is one of the empirical gas laws relating the effect of temperature on volume of a gas while pressure and mass (moles) of substance remain constant. Basically, Charle's Law states that the change in volume associated with a confined mass or gas is directly proportional to the applied temperature.

For a directly proportional relationship between Volume (V) and Temperature (T) the empirical formula is written V ∝ T. This is then set in equation form by including a 'proportionality constant' giving V = k·T. In applications, problems generally provide 'initial' Temperature (T₁) and Volume (V₁) along with a final Temperature (T₂) or final Volume (V₂) and asked to calculate the unknown variable. The Charle's Law relationship detailing this is derived as follows:

V = k·T => k = V/T

The k-value is constant for both the initial and final conditions such that...

k₁ = k₂ => V₁/T₁ = V₂/T₂

Example: Assume a gas volume of 25 liters at 25°C, what would be the gas volume if cooled to 0°C?

Set-up a data table

V₁ = 25L     & V₂ = ?

T₁ = 25°C   & T₂ = 0°C => these values need to be converted to Kelvin Temps so as to avoid division by '0'. So...

T₁ = (25 + 273)K = 298K     &     T₂ = (0 + 273)K = 273K

Substituting into V₁/T₁ = V₂/T₂ and solving for V₂ provides the new volume.

25L/298K = V₂/273K => V₂ = (25L)(273K)/(298K) = 22.9L ≅ 23L (2 sig. figs.)

Generally, to check work, examine the change in volume relative to the change in temperature. For a direct proportionality a decrease in temperature as in the example would give a decrease in volume consistent with Charle's Law. Note that 273K/298K  times  25L gives a smaller resulting volume value. If one applies '298K/273K' times the 25L,  a larger value would result and is inconsistent with Charle's Law.

Answer: m = nM= 242.8 g

Explanation: amount of MgCl2 is same as n(Mg)

M(MgCl2) = 95.21 g/mol

95.21 g/mol is the mass in grams of MgCl[tex]_2[/tex] are produced by 2.55 mol Mg in the reaction Mg + 2HCl ⟶ MgCl[tex]_2[/tex] + H[tex]_2[/tex].

A body's mass is an inherent quality. Prior to the discoveries of the concept of atom as well as particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to accelerate (change of velocity) in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

m = n×M= 242.8 g

M(MgCl[tex]_2[/tex]) = 95.21 g/mol

Therefore, 95.21 g/mol is the mass in grams of MgCl[tex]_2[/tex] are produced by 2.55 mol Mg in the reaction Mg + 2HCl ⟶ MgCl[tex]_2[/tex] + H[tex]_2[/tex].

it should be 50/50 percent

so 50%

hopefully this is right !

Answer:

The answer is A. I took the test today.

Explanation:

Answer: The empirical formula is [tex]CaS[/tex]

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of Ca= 55.6 g

Mass of S = 44.4 g  

Step 1 : convert given masses into moles.

Moles of Ca =[tex]\frac{\text{ given mass of Ca}}{\text{ molar mass of Ca}}= \frac{55.6g}{40.08g/mole}=1.38moles[/tex]

Moles of S =[tex]\frac{\text{ given mass of S}}{\text{ molar mass of S}}= \frac{44.4g}{32.06g/mole}=1.38moles[/tex]

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Ca = [tex]\frac{1.38}{1.38}=1[/tex]

For S = [tex]\frac{1.38}{1.38}=1[/tex]  

The ratio of Ca : S =  1:1  

Hence the empirical formula is [tex]CaS[/tex]

Answer:

a) distance is 4+7+1+8=20 blocks

b) displacement is 10 blocks

Explanation:

find displacement: x and y

x axis displacement = 4-1 = 3 blocks

y axis displacement = -7+8= 1 block

displacement = the square root of 3^2 + 1^2

= 9+1 = 10 blocks.

You can find the angle of displacement with respect to the initial position using trig identities, if you wish.

Answer:

Answer 'A'

Explanation:

There are 3 acid-base theories.

- Arrhenius Theory

- Bronsted-Lowry Theory

- Lewis Theory

In the Arrhenius and the Bronsted-Lowry Theories, for an acid to be an acid two requirements must be met. That is, the substance must be soluble in water and two, undergo ionization generating a hydronium cation (H₃O⁺) and a base anion (A⁻) in process; i.e., H-Anion + H₂O => H₃O⁺ + Anion⁻.

The Lewis Theory defines acids and bases in terms of electron pair donation (the base) and electron pair acceptor (the acid). This theory does not require the presence of an ionizable hydrogen in the substance of interest, only non-bonded electron pairs (base) and a cationic character that accepts electron pairs without violating the octet rule in chemical bonding.

For the purpose of answering your question, the Arrhenius and Bronsted-Lowry theories are sufficient for defining acids and bases undergoing ionization in aqueous media. With this, one should understand also that acids and bases are classified as strong acids and strong bases (compounds that ionize 100% aqueous media) or weak acids and weak bases (compounds that do not ionize 100% in aqueous media).

Strong Acids* include HCl, HBr, HI, HNO₃, HClO₄ & H₂SO₄ (1st ionization step only). Strong Bases include Group IA and Group IIA hydroxides except for Beryllium Hydroxides. The weak acids are compounds with ionizable hydrogens that are NOT members of the strong 6 listed above. The weak bases are ammonia and ammonia derivatives in aqueous media.

It is recommended that students only need to memorize the strong six acids in that any compound not one of these six with an ionizable hydrogen is a weak acid whether you know its name or not. The weak bases, as mentioned, are ammonia and ammonia derivatives in water. These compounds will undergo coordinate bonding to generate an ionizable compound containing an ammonium cation and hydroxyl anion. The reaction is as follows:

               RNH₂ + H₂O => RNH₃⁺OH⁻(aq) => RNH₃⁺(aq) + OH⁻(aq)

Typically, weak acids and weak bases undergo very limited ionization in the range of 1% to 2%. The compounds remaining are in concentrations of 98% - 99% unionized but form soluble homogeneous solutions.

If you have further questions, kick back a note. Doc

___________________-

*Some scholars include sulfurous acid (H₂SO₃) as a strong acid but analysis shows aqueous solutions - under special conditions - to contain unionized  H₂SO₃ and thus violates the 100% ionization requirement.
