Answer: b. Electrons are shared between atoms

Explanation: electrons are shared, forming molecules, covalent compounds have weaker forces holding the molecules together

Answer:

The mass percentage of water of crystallization in washing soda is 62.9 %. But the molar mass of Na2 CO3 • 10H2 O is 286.1412 g/mol and the Na2CO3 • 10H2O % by mass H2O.

SO your full answer is 286.1412 g/mol

Answer:

Mycelium is a group of hyphae which are fungus.... these are like roots in structure

Answer:

A mycelium is the vegetative part of a fungus, consisting of a network of fine white filaments

Explanation:

Answer:

height(h)=10 m

acceleration due to gravity (g)=10 m/s^2

mass (m)=?

potential energy=67

or,mgh= 67

or,m×10×10=67

or,m=67/100

or,m=0.67 kg

Therefore,m= 670 grams

Answer:

pentene

Explanation:

pentene is 5 carbon chain with a double bond. The ending -ene indicates presence of double bond.

Answer:

since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).

Answer:

You're in my science class wth

Explanation:

For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

Answer:

The muscoloskeletal system

Explanation:

The musculoskeletal system is made up of the body's bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. Its primary functions include supporting the body, allowing motion, and protecting vital organs.

Answer:

I probably think it's to achieve a higher energy state

Explanation:

-

Answer:

14.53ML

Explanation:

V1=218

V2=?

P2=15p1

USING BOYLE'S LAW

P1V1=P2V2

V2=P1V1/P2=P1(218ML)/15P1

=14.53ML

Answer:

c

Explanation:

troposphere is the answer

dipole: dipole interactions

- dispersion forces (London forces)

- hydrogen bonds

as the attractive forces between molecules becomes larger, it takes more energy to separate them

- as a result, vapor pressures, boiling points and melting points will be larger

occur between molecules that have a permanent dipole moment

- H-Cl----H-Cl

Answer:

5.83 g

Explanation:

First, you must start with a balanced equation so you can see the mole ratios.

NaOH + H₃BO₃ --> NaBO₂ + 2H₂O

You can see that it takes 1 mole of sodium hydroxide to form 1 mole of sodium borate. 1:1 ratio

Now you must calculate how many moles of NaOH 35.47 g equals.

Na = 22.99 amu

O = 15.99 amu

H = 1.008 amu

NaOH = 39.997 amu

35.47 g ÷ 39.997 amu = 0.08868 moles of NaOH

Since it's a 1:1 ratio, the same number of moles of NaBO₂ is created. Now you must convert moles to grams.

Na = 22.9 amu

B = 10.81 amu

2 O = 31.998 amu

NaBO₂ = 65.798 amu

0.08868 moles x 65.798 = 5.83 g

Answer: The partial pressure of [tex]N_{2}O[/tex] is 0.35 atm.

Explanation:

Given: Total pressure = 0.98 atm

Partial pressure of [tex]O_{2}[/tex] = 0.48 atm

Partial pressure of Ar = 0.15 atm

Partial pressure of [tex]N_{2}O[/tex] = ?

Total pressure is the sum of partial pressure of each component present in a mixture of gases.

Hence, partial pressure of [tex]N_{2}O[/tex] is calculated as follows.

Total pressure = [tex]P_{N_{2}O} + P_{O_{2}} + P_{Ar}[/tex]

Substitute the values into above formula as follows.

[tex]Total pressure = P_{N_{2}O} + P_{O_{2}} + P_{Ar}\\0.98 atm = P_{N_{2}O} + 0.48 atm + 0.15 atm\\P_{N_{2}O} = 0.35 atm[/tex]

Thus, we can conclude that the partial pressure of [tex]N_{2}O[/tex] is 0.35 atm.

Answer:

Thus,there are 0.2 mole in 8 g of calcium.

Answer:

nucleotides

Explanation:

The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. ... DNA is made of chemical building blocks called nucleotides.

hope that helped :)

Answer:

Ores mined from shields.

Explanation:

Ores mined from shields are the source from which we get the history of Precambrian rocks. The Ores from shield experience the Precambrian era so that's why its rocks provides information about that era. The Precambrian supereon is the division of the geological time scale which is the first and longest stage in the history of the Earth which also includes the Hádic, Archaic and Proterozoic eons.

Answer:

The term science fiction was popularized, if not invented, in the 1920s by one of the genre's principal advocates, the American publisher Hugo Gernsback. The Hugo Awards, given annually since 1953 by the World Science Fiction Society, are named after him.
