Answer: hydrogen bonding

Explanation:

Ionic bond is formed by the transfer of electrons between metals and non metals.

Covalent bond is formed by sharing of electrons between two non metals.

Hydrogen bond is the bond formed between hydrogen and an electronegative atom such as fluorine, oxygen and nitrogen.

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom and thus are bonded by cohesive forces of hydrogen bonds.

Each water molecule consists of two atoms of the element hydrogen joined to one atom of the element oxygen. An interesting property of water is the ability of its molecules to “stick together.” This occurs because one side of each water molecule is slightly negative and the other side is slightly positive. The positive portion of a water molecule is attracted to the negative portion of an adjacent water molecule. As a result, water molecules are called polar molecules. They attract other water molecules like little magnets. It is most likely ionic bonding but between hydrogen and oxygen it is covalent.

1. Calculate the momentum of a 1,500 kg car traveling at 6 m/s.
ziro4ka [17]

Answer:

1.9000kgm/s

2.258,000kgm/s

Explanation:

1.Momentum is given as the product of mass by velocity of an object.

Momentum,p=mv

m=1,500kh, v=6m/s

p=1500*6\\p=9000kgm/s

2.Momentum,p=mv

m=7800kg, v=30m/s

p_1=7800*30\\p_1=234,000kgm/s\\

new mass=7800+800=8600

As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

p_2=8600*30\\p_2=258,000kgm/s

If the human body contains about 50 deciliters of blood, and the blood has about 15 grams of hemoglobin per deciliter, and all o
Tcecarenko [31]

Answer:

The blood will contain 750 grams of O2

Explanation:

Volume of blood in the human body = 15 deciliters

Mass of hemoglobin per deciliter of blood = 15 grams

Mass of hemoglobin in 50 deciliters of blood = 50×15 = 750 grams

Since all the hemoglobin molecules are saturated with O2, mass of O2 in the blood will be the same as mass of hemoglobin molecules in the blood.

Therefore, mass of O2 in the blood is 750 grams

Predict the order of acid strengths in the following series of cationic
stich3 [128]

Answer:

CH3CH=NH2+>CH3CH2NH3+

Explanation:

If we look at the both species under review, we will realize that they are both amines hence they possess the polar N-H bond.

Electrons are ordinarily attracted towards the nitrogen atom hence making both compounds acidic. It is worthy of note that certain features of a compound may make it more acidic than another of close structural proximity. 'More acidic' simply means that the proton is more easily lost.

CH3CH=NH2+ contains an sp2 hybridized carbon atom which is highly electronegative and further withdraws electron density from the N-H bond thereby leading to a greater acidity of CH3CH=NH2+ compared to CH3CH2NH3+
