Why does the dime transfer less momentum?
1 answer:
Answer:
This because the mass of the dime is very less = 2.268 grams only
Explanation:
Momentum :<em><u> It is product of mass and velocity of the objec</u></em>t.The affect of momentum can be observed by the force exerted <em><u>. Greater the change in momentum, greater the force exerted by the object</u></em>.
The formula of momentum(p) is :
Momentum depends upon :
1. Mass = Greater the mass of the object , greater the momentum . For example : you get more hurt by a heavy stone then a light ball when both hit you with the same velocity.
2. Velocity = Momentum of the object with more velocity is more. This application is used by the cricketers. While catching the ball , the fielder pushes his hand away. By doing this he decreases the velocity of the object. Hence the momentum decrease and the ball comes to catcher's hand easily.
The mass of dime = 2.26 gram So it has less momentum because of less mass.
Hence the force exerted or the momentum transferred by the Dime is very low .

Answer:
4.08 grams
Explanation:
Essentially, we're looking for the mass of HCl that "matches" 3.26 grams of magnesium hydroxide.
First, convert 3.26 grams of into moles by dividing by the molar mass. The molar mass of
is 24.3 + 16 * 2 + 1 * 2 = 58.3 g/mol. So, 3.26 grams is equal to:
3.26 g ÷ 58.3 g/mol = 0.0559 mol
Notice that from the chemical equation, magnesium hydroxide and hydrochloric acid (HCl) have a ratio of 1 to 2. In other words, for every 0.0559 moles of , there are 0.0559 * 2 = 0.112 moles of HCl.
Finally, convert moles of HCl to grams by multiplying 0.112 by the molar mass, which is 1 + 35.45 = 36.45 g/mol:
0.112 mol HCl * 36.45 g/mol = 4.08 g HCl
The answer is thus 4.08 grams.
