You can shift weight to the front of your vehicle by __________ .

Chemistry
2 answers:
Flura [38]3 years ago

We can change or shift vehicle weight by

a) change in speed  (by accelerating and by braking)

b) change in direction (turning left or right)

Now there is a physics behind the shift in weight based on braking and accelerating.

You can shift weight to the front of your vehicle by braking.

Similarly, we can shift weight to back by accelerating.

Bending or turning left will transfer weight to right

Bending or turning right will transfer weight to left

Ammonium dihydrogen phosphate, formed from the reaction of phosphoric acid with ammonia, is used as a crop fertilizer as well as
Tema [17]

Answer:

a)The mass percentages of nitrogen and phosphorus in the compound is 24.34% and 26.95% respectively.

b) 14.78 grams ammonia is incorporated into 100. g of compound.

Explanation:

a) Ammonium dihydrogen phosphate that is NH_6PO_4.

Molecular mass of ammonium dihydrogen phosphate = M

M = 115 g/mol

Percentage of an element in a compound:

\frac{\text{Number of atoms of element}\times \text{Atomic mass of element}}{\text{molecular mass of element}}\times 100

Percentage of nitrogen:

\frac{1\times 28 g/mol}{115 g/mol}\times 100=24.34\%

Percentage of phosphorus:

\frac{1\times 31g/mol}{115 g/mol}\times 100=26.95\%

b) Percentage of ammonia in 1 molecule of ammonium dihydrogen phosphate.

Molar mass of ammonia = 17 g/mol

\%=\frac{17 g/mol}{115 g/mol}\times 100=14.78\%

Amount of ammonia in 100 grams of compound:

14.78% of 100 g of ammonium dihydrogen phosphate:

\frac{14.78}{100}\times 100 g=14.78 g

14.78 grams ammonia is incorporated into 100. g of compound.

An ion has 14 neutrons, 10 electrons, and a mass number of 27 what element
nasty-shy [4]

The ion is Al³⁺

mass number - number of neutrons= atomic number

27 - 14 = 13

Aluminum has an atomic number of 13, thus we know this is the metal in question. Also, because the aluminum has only 10 electrons, (3 less than a neutral atom of aluminum would have), its charge must be 3+

Which statement is true about AC?
AysviL [449]

According to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.

<h3>What is AC?</h3>

It is the flow of electric charges through a conductor is called electric current, if said flow of electric current varies in direction from time to time, we speak of alternating current.

Subatomic particles such as protons and electrons have an electrical charge, a physical property that is manifested by the repulsive and attractive forces that exist between them in AC the electrical charge moves back and forth.

Therefore, we can conclude that according to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.

How much energy is needed to change 44 grams of ice at -8° to steam at 107°?
Tpy6a [65]
Q=m(c∆t +heat of fusion + heat of evaporation)

m= 44g
c= 4.186 J/g.C
∆t= 107-(-8) =115 C
heat of fusion= 333.55 J/g
heat of evaporation=2260 J/g

Q=44(4.186*115 + 333.55 + 2260)
Q= 135297.36 J
