What type of plant rarely grows in the grasslands?

Answer:

Boyle's Law

Explanation:

"Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases."

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:

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:

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

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:

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

Answer:

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.

Urban development has been linked to many environmental problems, including air pollution, water pollution, and loss of wildlife habitat. Urban runoff often contains nutrients, sediment and toxic contaminants, and can cause not only water pollution but also large variation in stream flow and temperatures.

P1 = 475 torr

P2 = 900 torr

V1 = 1500 mL

V2 = ?

Applying Boyle's Law

P1V1 = P2V2

475 torr × 1500 mL = 900 torr × V2

V2 = 475 * 1500 mL / 900

V2 = 475*5/3 = 791.6 mL

                                                  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)

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.
