Which of the following graphs correctly represents the relationship between the pressure and the volume of an ideal gas that is held at constant temperature

Answer:

Answer:

1,110.48 mL

Explanation:

37°C is 310K and 132°C is 405K

V/V' = T/T'

850/V' = 310/405

V' = (850×405)/310

=> V' = 1110.48 mL

im pretty sure its a push or pull thing

Explanation:

Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.

Answer:

Name of the compound is aluminum sulphate. chemical formula Al2(SO4)3

In that compound there are two aluminum atoms; three sulphur and 4*3=12 oxygen atoms.

2 oxygen atoms is equivalent to 1 mole oxygen.

so 12 oxygen is equivalent to 12÷2=6 mole oxygen.

Answer:

C. OH^-

Explanation:

When base is dissolved in a solution it will form [tex]OH^{-}.[/tex]

A base is just a chemical that neutralizes an acid by reacting with hydrogen ions. The majority of bases are minerals that combine with acids to produce water and salts.

A mixture of more than one type of component is introduced as solution.

When base will dissolve in water then it will given hydroxyl ion. It can be written as.

NaOH ⇒[tex]Na^{+}+OH^{-}[/tex]

NaOH give [tex]OH^{-}.[/tex] that's why it can be referred as base.

Hence, OH- ion will form when base will be dissolved in solution.

Answer:

66.2 % of O

Explanation:

Our compound is the lithium nitrite.

LiNO₂

This salt is ionic and can be dissociated: LiNO₂ →  Li⁺ + NO₂⁻

We determine the molar mass:

molar mass of Li + 3 . molar mass of N + 6 . molar mass of O

6.94 g/mol + 3. 14 g/mol + 6 . 16 g/mol = 144.94 g/mol

The mass of oxygen contained in 1 mol of lithium nitrite is:

6 . 16 g/mol = 96 g

So the percentage of oxygen present is:

(96 g / 144.94 g) . 100 = 66.2 %

Answer:

it is Thy First option

Explanation:

Answer:

0.018 grams

Explanation:

The number of moles (n) in such number of atoms of Aluminum must be calculated by dividing the number of atoms (nA) by Avagadro's number i.e.

n = nA ÷ 6.02 × 10^23atoms

The number of atoms of Aluminum in this question has been given as: 3.99 x 10^20 atoms.

n = 3.99 x 10^20 ÷ 6.02 × 10^23

n = 3.99/6.02 × 10^(20-23)

n = 0.663 × 10^-3

n = 0.000663moles

Next, we convert the mole value to mass in grams by using the formula;

mole = mass/molar mass

mass = mole × molar mass

Molar mass of Al = 27g/mol

mass (g) = 0.000663 × 27

mass = 0.0179

mass of Aluminum is 0.018grams

moles PbI₂ produced = = 0.9 mole (1 sig. fig.)

Explanation:

Given                   Pb(NO₃)₂  +    2KI     −−>    PbI₂ + 2KNO₃

                                                  300g         ?moles

moles KI = 300g KI/166g/mol = 1.81 mole KI

Rxn ratio for KI and PbI₂ => 2:1

∴ moles PbI₂ produced = 1/2(1.81 mole) = 0.9036144 mole (calculator answer)

= 0.9 mole (1 sig. fig.)

Cloudy with precipitation occurs due to rising and cooling causing water vapor to condense.

Weather along most fronts is usually cloudy with precipitation because the warm air present along most fronts usually rising and cooling which causes water vapor to condense. Warm fronts often bring stormy weather as the warm air rises above the cool air mass that makes clouds and storms.

These clouds form in the warm air that is located high above the cool air. As the front passes over a region, the clouds become lower which leads to rainfall so we can conclude that cloudy with precipitation occurs due to rising and cooling causing water vapor to condense.

Answer:

iron gets rusted as it is more reactive then aluminium and reacts faster with moisture in the air

Explanation:

Answer:

A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. What is the specific heat capacity of iron?

Explanation:

The amount of heat absorbed by the gold is 339.1 joules, which was calculated by the formula of specific heat capacity.

Specific heat capacity, often just called “specific heat”, is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius (or one Kelvin).

To calculate the amount of heat absorbed by the gold, we can use the formula:

Q = m × c × ΔT

where:

Q = heat absorbed (in joules)

m = mass of the gold (in grams)

c = specific heat capacity of gold (in joules per gram per degree Celsius)

ΔT = change in temperature of the gold (in degrees Celsius)

The specific heat capacity of gold is 0.129 J/g°C.

Substituting the given values into the formula, we get:

Q = 15.5 g × 0.129 J/g°C × (177.4°C - 4.5°C)

Q = 15.5 g × 0.129 J/g°C × 172.9°C

Q = 339.1 J

Therefore, the amount of heat absorbed by the gold is 339.1 joules.

Answer:

0.21 mole of NaCl

Explanation:

From the question,

using Avogadro's Constant,

1 mole of every compound contains 6.02×10²³ molecules of that compound.

I.e

1 mole of NaCl ⇒ 6.02×10²³ molecules of NaCl

x moles of NaCl ⇒ 1.25××10²³ molecules of NaCl

Solving for x,

x moles of NaCl = (1 mole of NaCl)×(1.25×10²³ molecules of NaCl)/(6.02×10²³ molecules of NaCl)

x moles of NaCl = (1×1.25×10²³)/6.02×10²³

x = 0.208 mole of NaCl

x ≈ 0.21 mole of NaCl
