A forecaster studying the climate of an area would find average yearly precipitation most helpful.

Forecaster studying of climate tells about the changes which will occur in the atmosphere in the upcoming future time.

Forecasting is done by measuring various environmental factors for the prediction of atmosphere. As it will given information about the percent of rainfall in the upcoming days, amount of precipitation, snowfall and so on.

Hence, option (A) is correct.

Answer:

b. d. f. h

Explanation:

Anions are negatively charged. They are usually non metals with few exceptions. They need to gain electrons in order to form and they are always listed after cation in a compound.

Answer:

Option C.

Ilegal dumping of waste

Explanation:

This is because non point source of pollution refers to source of pollution that are many and not directly one which is illegal or does not meet the legal term. This type of pollution does not have a point source, it has many sources and this type of pollution is cause by rainfall or precipitation. Where when the rain fall, it wash away the waste through to water bodies, causing pollution and endangering water bodies.

Answer:

Since the force applied at both ends is acting in opposite directions, then the resultant force becomes negative.

The answer to the question is (3) K2SO4

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].

Explanation:

Answer:

A: 0.67

The situation described in the question is analogous to a semipermeable membrane. Water is able to pass through aquaporin channels present in the liposome, but large uncharged particles (glucose) and ions (K+ and Cl -) are impermeable and will remain trapped within the liposome. If assumed to be ideal, the osmotic pressure, π, exerted by the solution due to molarity differences across the membrane is defined as π = iMRT, where i is the van't Hoff factor, M is the molarity of the solution, R is the universal gas constant, and T is the absolute temperature of the solution. A change in osmotic pressure at constant temperature is due to changes in iM, a term that is equivalent to the concentration of dissolved particles produced by solute in solution. When compared to the original volume of 1 M glucose, the new combined solution has twice the volume and three times the number of dissolved particles (1 M KCl, a strongly electrolytic solution, produces 1 M concentrations of both K+ and Cl- in solution), or an increase in the concentration of dissolved particles by a factor of 1.5. This is equivalent to a combined molarity of dissolved particles of 1.5 M. The ratio of osmotic pressure is then [1 M dissolved glucose] / [1.5 M dissolved glucose + KCl] = 0.67

Answer:

10.0 g of AgI will produce 5.28 g of Ag₂S

Explanation:

The balanced equation of the reaction is given below:

2AgI + Na₂S ----> Ag₂S + 2NaI

From the equation of reaction, 2 moles of AgI produces 1 mole of Ag₂S

The moles of a substance is related to its mass by a quantity known as molar mass which is defined as the mass of one mole of that substance.

Molar mass of AgI = (108 + 127) g = 235 g

Molar mass of Ag₂S = (108 × 2 + 32) g= 248 g

Mass of 2 moles of AgI = 2 × 235 g = 470 g

470 g of AgI produces 248 g of Ag₂S

10 g of AgI will produce 248 /470 × 10 g of Ag₂S = 5.28 g

Therefore, mass of Ag₂S produced = 5.28 g

Explanation:

Answer:

The volume of solution in liters required to make a 0.250 M solution from 3.52 moles of solute is 14.08 liters of solution

Explanation:

The question relates to the definition of the concentration of a solution which is the number of moles per liter (1 liter = 1 dm³) of solution

Therefore we have;

The concentration of the intended solution = 0.250 M

Therefore, the number of moles per liter of the required resolution = 0.250 moles

Therefore, the concentration of the required solution = 0.250 moles/liter

The volume in liters of the required solution that will have 3.52 moles of the solute is given as follows;

The required volume of solution = The number of moles of the solute/(The concentration of the solution)

∴ The required volume of solution = 3.52 moles/(0.250 moles/liter) = 14.08 liters

The required volume of solution to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.

Therefore the number of liters required to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.

Answer:

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

Explanation:

La reacción balanceada es:

3 Zn+ 2 H₂PO₄ → Zn₃(PO₄)₂ + 2 H₂

Por estequiometria de la reacción (es decir, la relación entre la cantidad de reactivos y productos en una reacción química), las siguientes cantidades de moles de cada compuesto participan de la reacción:

Entonces podes aplicar la siguiente regla de tres: si por estequiometria 3 moles de zinc produce 1 mol de fosfato de zinc, 9 moles de zinc cuántos moles de fosfato de zinc producirá?

[tex]moles de fosfato de zinc=\frac{9 moles de zinc*1 mole de fosfato de zinc}{3 moles de zinc}[/tex]

moles de fosfato de zinc= 9

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

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.
