A chemical process with an e-factor of 1 creates less waste than an e-factor of 25?
The statement given "A chemical process with an e-factor of 1 creates less waste than an E-factor of 25" is True.
E factor :The E factor takes into account all waste that may be classified as trash, including byproduct waste, residual reactants, solvent losses, spent catalysts and catalyst supports, and any other waste that can be classified as waste. The computation is based on the definition of waste. Since water is typically safe and a considerable byproduct of many chemical processes, its bulk is typically excluded from the calculation of the total mass of waste. Higher E values are generally less desirable and 0 is the ideal E factor. The volume of product produced and the product's value determine the e variables that may be tolerated. Tolerable E factors for bulk chemicals generated in quantities ranging from hundreds of thousands to millions of tons per year typically fall between 1 and 5.Learn more about the Green chemistry with the help of the given link:

The deceleration of the rocket sled if it comes to rest in 1.1 s from a speed of 1000 km/h is [tex]252.52\ m/s^2[/tex].
The acceleration in opposite direction is known as the deceleration. Basically the deceleration is negative value of the acceleration since the negative sign depicts its opposite in direction.
The given data:
time, t = 1.1 s
initial speed, u = 1000 km/h = [tex]\frac{2500}{9}\ m/s[/tex]
final speed, v = 0 m/s
So we will be using the equation of motion, that is,
v = u + at
[tex]\therefore 0=\frac{2500}{9} + a(1.1)[/tex]
[tex]\Rightarrow a=-\frac{2500}{9(1.1)}[/tex]

What is the seal's average speed during the chase?
The seal's average velocity during the chase is 1.67 m/s.
The seal's average speed during the chase is 5 m/s.
What is average velocity?
The average velocity of an object is the change in the displacement of the object with time.
The seal's average velocity during the chase is calculated as follows;
Δx = xf - xi
Δx = 20 m - 10 m = 10 m
v = Δx/t
v = 10 m / 6 s
v = 1.67 m/s
Average speed of the sealThe average speed is the ratio of total distance to total time of motion.
v = (10 m + 20 m) / 6 s
v = 30 m / 6s

To increase the electric force between two charged particles by a factor of 16, we D. Increase one particle's charge by a factor of 16.
What is electric force?Electric force is the force of attraction between two charged particles.
The magnitude of the electric force is given by F = kq₁q₂/r² where
k = electrostatic constant, q₁ = charge on particle one, q₂ = charge on particle two and r = distance of separation between the two charges.Given that we have two charged particles q₁ and q₂ separated by a distance r, the electric force betwen them is given by F = kq₁q₂/r²
Now, if we want to increase the force by a factor 16, we have the new force F' = 16F
F' = 16kq₁q₂/r²
F' = k16q₁q₂/r²
F = k(16q₁)q₂/r² or kq₁(16q₂)/r²
This implies that either one of the charged particles q₁ or q₂ is increased by a factor of 16

The average speed of the complete round trip is 65.57 km / h.
We need to know about the average speed to solve this problem. The average speed can be determined as the total distance divided by the total time. It can be written as
v = d / t
where v is average speed, d is distance and t is time.
From the question above, we know that
d1 = 300 km
v1 = 93 km/h
t lunch = 1 hour
d2 = 300 km

By using ideal gas approximation, the sun's temperature is 2.27 x 10⁷ K.
We need to know about ideal gas to solve this problem. The ideal gas will follow the rule
P . V = n . R . T
where P is pressure, V is volume, n is the amount of substance, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.
From the question above, we know that:
Mr = 2 g/mol
ρ = 1.4 g/cm³
P = 1.3 x 10⁹ atm = 1.32 x 10¹⁴ Pa
m(sun) = 1989 x 10³⁰ g

n = m / Mr
n = 1989 x 10³⁰ / 2
n = 994.5 x 10³⁰ mol
Find the volume of sun

V = 1989 x 10³⁰ / 1.4
V = 1420.71 x 10³⁰ cm³

If the price elasticity of demand for digital cameras is 0.88, then the demand is _____ and total revenue will ______ if the price of cameras increases.
Digital camera demand is inelastic if the price elasticity of demand is 0.88, meaning that price rises for cameras will result in higher overall sales.
By price elasticity, what do you mean?Price elasticity of demand measures how much a product's consumption changes in response to price changes. If a good's price elasticity is infinite, it is perfectly elastic (if demand changes substantially even with minimal price change). The good is elastic if price elasticity is more than 1, and inelastic if it is less than 1. A good is completely inelastic if its price elasticity is zero, meaning that no amount of price variation will alter demand. The quantity effect will be overpowered by the price effect. The relationship between the percentage change in a product's quantity demanded and the percentage change in price is known as price elasticity of demand. It helps economists comprehend how supply and demand shift in response to changes in a product's price.
