Answer:
1.
2.
Explanation:
1.Momentum is given as the product of mass by velocity of an object.
Momentum,
m=1,500kh, v=6m/s

2.Momentum,
m=7800kg, v=30m/s

new mass=7800+800=8600
As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

I’m not sure, but I think A. from an internal engine reservoir
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
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+
Answer:
synthesis reaction
The chemical reaction 2H2+O2→2H2O 2 H 2 + O 2 → 2 H 2 O is classified as a synthesis reaction
