Answer

Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.

Explanation:

Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.

Answer:

648.7g of Mg must be added

Explanation:

Based on the reaction:

3Mg + 1/2P4 → Mg3P2

3 moles of Mg produce 1 mole of Mg3P2

To solve this problem we neeed to find the moles of Mg3P2 in 1200g. With these moles and the chemical reaction we can finf moles of Mg and its mass:

Moles Mg3P2 -Molar mass: 134.88g/mol-:

1200.0g Mg3P2 * (1mol / 134.88g) = 8.897 moles of Mg3P2

Moles Mg:

8.897 moles of Mg3P2 * (3mol Mg / 1mol Mg3P2) = 26.69 moles of Mg

Mass Mg -Molar mass: 24.305g/mol-:

26.69 moles of Mg * (24.305g / 1mol) =

Answer: The lowest possible whole number coefficient for water is 1.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble  water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical reation for aqueous solutions of lithium hydroxide and acetic acid react to yield lithium acetate and water is:

[tex] LiOH(aq)+CH_3COOH(aq)\rightarrow CH_3COOLi(aq)+H_2O(l)[/tex]

Thus the lowest possible whole number coefficient for water is 1.

In the balanced equation for given reaction, the lowest possible whole number coefficient for water is one.

Stoichiometry of any reaction will tells about the relative amount of species presents before and after the chemical reaction.

Reaction between the lithium hydroxide and acetic acid is a neutralization reaction, as here lithium hydroxide is a base and acetic acid is a acid as a result of which it produces water molecule and lithium salt of acetate. And balanced equation for this will be represented as:

LiOH(aq) + CH₃COOH(aq)  CH₃COOLi(aq) + H₂O(l)

In the above equation all entities are present in equal amounts on both the sides and from the stoichiometry of the reaction it is clear that coefficient of water is 1.

Hence, 1 is the whole number coefficient for water.

The aspect of the environmentally sustainable society has not been soil erosion.

An environmentally sustainable society has been the one that has been able to meet the current and future needs of the generation. The plantation of trees, reducing the greenhouse effect, and the method for the generation of a sustainable environment has been the characteristic of a sustainable society.

The soil erosion results in damage to the soil with the flow of the upper layer of soil from the water flow. The soil erosion will be resultant in damage to the environmentally sustainable society.

Answer:

0.600 g/cm³

Explanation:

Step 1: Given data

Step 2: Calculate the volume of the cylinder

First, we have to determine the radius, which is half of the diameter.

r = d/2 = 2.34 cm/2 = 1.17 cm

Then, we use the formula for the volume of the cylinder.

V= π × r² × h

V= π × (1.17 cm)² × 6.62 cm

V = 28.5 cm³

Step 3: Calculate the density (ρ) of the sample

The density is equal to the mass divided by the volume.

ρ = m/V

ρ = 17.1 g/28.5 cm³

ρ = 0.600 g/cm³

Answer:

The excited state electron configuration of an atom indicates the promotion of a valence electron to a higher energy state.

The molarity of a solution : 2.24

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Where

M = Molarity

n = number of moles of solute

V = Volume of solution (L)

4.83 moles of NaCl in 2.16 L solution

n = 4.83

V = 2.16 L

Molarity :

Answer:The Cl atom should transfer two electrons to Ca because it has more electrons

than Ca, so the formula becomes CaCl2.

Explanation: i took the quiz

Calcium forms ionic compound with two chlorine atoms as CaCl₂. Hence, Ca atom should transfer only one electron to one chlorine and the second electron is given to second Cl.  Thus, option C is correct.

Ionic bond is formed between a metal and non metal by losing electron from the metal. The non metal should be an electronegative atom to accept that electron and forms a negative charge.

While the metal forms a partial positive charge. This charge separation make them attractive each other and make it ionic.

Ca is a second group element have two valence electrons. Ca forms compounds with halogens by donating its two electrons  each to two halogen atoms and make a dihalide.

Cl have 7 electrons and tends to accept one electron from the metal to complete its octet. Thus one chlorine need only one electron from Ca. The second electron is then transferred to a second chlorine atom.

Therefore, the CaCl₂ compound is formed by transferring two electrons from calcium into two chlorine atom. Hence, option C ic correct.

Answer:

0.0500L of 3.00M HCl are needed to react completely

Explanation:

Hydrochloric acid HCl reacts with sodium carbonate, Na2CO3, as follows:

2HCl + Na₂CO₃ → 2NaCl + H₂O + CO₂

Where 2 moles of HCl reacts per mole of Na₂CO₃

To find the volume of 3.00M HCl needed to react completely we need first to calculate the moles of Na₂CO₃ added and, with this chemical equation we can solve for moles of HCl as follows:

Moles Na₂CO₃:

0.750L * (0.100moles Na₂CO₃ / L) = 0.0750moles

Moles HCl:

0.0750moles Na₂CO₃ * (2 moles HCl / 1 mole of Na₂CO₃) = 0.150 moles of HCl

Volume of 3.00M HCl:

0.150 moles of HCl * (1L / 3.00moles) =

Answer:

A. Whenever the population has increased, steel consumption has increased as well.

Explanation:

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen  on the graph is that whenever the population has increased, steel consumption has increased as well.

A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.

The net ionic equation for the reaction between iron (iii) sulfate and potassium hydroxide is

Fe³⁺(aq) + 3OH¯(aq) —> Fe(OH)₃(s) (Option B)

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

In solution

Fe₂(SO₄)₃ (aq) --> 2Fe³⁺(aq) + 3SO₄²⁻(aq)

KOH (aq) --> K⁺(aq) + OH¯(aq)

The reaction proceeds as follow

Fe₂(SO₄)₃ (aq) + KOH (aq) —>

Fe³⁺(aq) + SO₄²⁻(aq) + K⁺(aq) + OH¯(aq) —> Fe(OH)₃(s) + SO₄²⁻(aq) + K⁺(aq)

Cancel out the spectator ions (i.e SO₄²⁻ + K⁺) and balance to obtain the net ionic equation

Fe³⁺(aq) + 3OH¯(aq) —> Fe(OH)₃(s)
