Answer:
0.682L or 682mL
Use Charles Law of V1/T1 = V2/T2
V1 = 0.6L
T1 = 293K
V2=?
T2= 333K

Answer:
See explanation and image attached
Explanation:
My aim is to convert 1-bromobutane to butanal. The first step is to react the 1-bromobutane substrate with water. This reaction occurs by SN2 mechanism to yield 1-butanol. Hence reagent A is water.
1-butanol is now reacted with an oxidizing agent such as acidified K2Cr2O7 (reagent B) to yield butanal. Note that primary alkanols are oxidized to alkanals.
These sequence of reactions are shown in the image attached.
Answer: dilute
Explanation:
A concentrated solution which is used to prepare solutions of lower concentrations by diluting it with addition of water.
A dilute solution is one which contains lower concentration.
Using Molarity equation:
=concentration of stock solution = 0.150 mol/L
= volume of stock solution = 10.0 ml
= concentration of dilute solution = ?
= volume of dilute solution = (10.0+90.0) ml = 100.0 ml
As the concentration is less than the original concentration, the solution is termed as dilute.

Cuando se encuentra en el interior de la tierra es nombrado concretamente magma y lava cuando es expulsada a la superficie. ... comienza a fundirse y el final de fusión (punto líquido) la roca esta parcialmente fundida. ... por su color oscuro, son más calientes que los magmas ácidos o félsicos (claros)
Answer:
166,600J
Explanation:
Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;
K.E = 1/2 × m × v²
Where;
K.E = kinetic energy (joules)
m = mass of body (kg)
v = speed or velocity (m/s)
According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.
K.E = 1/2 × 833 × 20²
K.E = 1/2 × 833 × 400
K.E = 1/2 × 333200
K.E = 166,600
Therefore, the kinetic energy of the roller coaster car is 166,600J.
