The answer for the following questions is explained below.
Explanation:
The two variables that affect kinetic energy are:
- mass and
- velocity
- velocity - The faster an object moves,the more the kinetic energy it has.
- mass - Kinetic energy increases as mass increases
The kinetic energy of an object depends on both its mass and its velocity
Kinetic energy increases as mass increases
For example,think about rolling a bowling ball and a golf ball down a bowling lane at same velocity
Here,the bowling ball has more mass than the golf ball
Therefore you use more energy to roll the bowling ball than to roll the golf ball
The bowling ball is more likely to knock down the pins because it has more kinetic energy than the golf ball
molar mass Mg = 24 g/mol ; MgF2 = 62 g/mol
<span>Mg + 2 NaF = MgF2 + 2 Na
</span>
24 g Mg ------------ 62 g MgF2
5.50 g Mg ---------- ( mass MgF2)
mass MgF2 = 5.50 x 62 / 24
mass mgF2 = 341 / 24
= 14.208 g of MgF2
hoope this helps!
Answer:
The moles of sucrose that are available for this reaction is 0.0292 moles
Explanation:
Combustion is an specifyc reaction where the reactants react with O₂ in order to produce CO₂ and H₂O
This combustion is: C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
We have to conver the mass to moles, to find out the limiting reactant
10 g . 1 mol / 342 g = 0.0292 moles of sucrose
8 g . 1mol / 32g = 0.250 moles of O₂
The moles of sucrose that are available for this reaction is 0.0292 moles
Before we start to work with the equation we must find the limiting reactant. When you find it, you can do all the calculations.
Answer:
An aldose is defined as a monosaccharide whose carbon skeleton has an aldehyde group. Ketose is a monosaccharide whose carbon skeleton has a ketone group.
