Answer:

178.98 sq. feet

Explanation:

The path and the garden has been shown in the figure below. The green area is the garden and the area in brown is the path.

It has been given that,

Radius of garden = 8 feet

So, the area of garden = 3.14 × 8 × 8 = 200.96 sq. feet

The total radius of the land including garden and path = 8 + 3 = 11 feet

So, the total are of land including garden and path = 3.14 × 11 × 11 = 379.94 sq. feet

So, the area of path = Total area of the land - area of garden

Area of path = 379.94 - 200.96 = 178.98 sq. feet

Why does water evaperate
Juli2301 [7.4K]

Explanation:

water evaporates because when h2o (water) particles heat up, they gain energy causing them to start to vibrate. this moves the oarticles further and further away from eachother and making the substance less dense, and turning it into a gas. meaning it has evaporated

What volume will be occupied by 5.00 mol of a gas at 25°C and 0.500<br> atm pressure?"
fomenos

Answer:

The volume will be occupied is 244, 36L.

Explanation:

We convert the unit of temperature to celsius into Kelvin, then use the ideal gas formula, solve for V (volume) and use the gas constant R =0.082 l atm / K mol:

0°C=273K  25°C= 273 + 25=298K

PV=nRT ---> V=nRT/P

V= 5,00 mol x 0,082 l atm/ K mol x 298 K/0,500 atm

<em>V=244,36L</em>

What is the reason for the low solubility of LiF (0.27 g
Brut [27]

Answer:

The answer is C. The high solvation energy for LI+

Explanation:

LiF has lower solubility because of the high solvation energy of Li+ ion. This is due to the smaller  size and very big charge compared to Cs+ ion which has a bigger size and solvent molecules easily surround it.

Solvation energy is simply the amount energy that is required to make a solute dissolve in a solvent.

Wine goes bad soon after opening because the ethanol ch3ch2oh in it reacts with oxygen gas o2 from the air to form water h2o and
maks197457 [2]
1) Chemical reaction

CH3 CH2 OH + O2 ---> CH3COOH + H2O

It is balanced

2) Molar ratios

1 mol CH3 CH2OH : 1 mol O2 : 1 mol CH3COOH : 1 mol H2O

3) Conversion of 7.6 grams of ethanol to moles

Molar mass of CH3CH2OH = 2 * 12g/mol + 6 * 1 g/mol + 16 g/mol = 46 g/mol

moles = mass / molar mass = 7.6 g / 46g/mol = 0.165 mol

4) Use of proportions with the molar ratios:

1mol CH3CH2OH / 1mol O2 = 0.165 mol CH3CH2OH / x => x = 0.165 mol CH3CH2OH.

5)  Conversion of 0.165 mol O2 to grams

mass in grams = number of moles * molar mass = 0.165 mol * (2 * 16g/mol)

mass = 5.28 g ≈ 5.3 g

Answer: 5.3 g
