The rate of the reaction is approximately 0.248 grams per second.
The rate of a reaction is determined by the change in the concentration of reactants or products with respect to time. In this case, the mass of a reactant decreases by 58g over a time interval of 233 seconds. To calculate the rate, we can divide the change in mass by the time elapsed:
Rate = Change in mass / Time
Rate = 58g / 233s ≈ 0.248 g/s
This value represents the rate at which the reactant is being consumed during the reaction. It's important to note that the units of the rate are consistent with the units of the given data (grams and seconds). This rate provides insight into how quickly the reaction is progressing in terms of reactant consumption.

Answer:
The height of the cliff is .
Explanation:
Given: Projectile is launched horizontally at a speed ofMeters per second from the top of a cliff and strikes a level surface below, seconds later. Projectile is launched horizontally from the same location at a speed of meter per second.
Using the formula of motion:
Substiuting all the values:
Let be the height of the cliff.
Hence, height of the cliff is .
Learn more about Laws of motion here:
consider the motion of projectile A in vertical direction :
v₀ = initial velocity of projectile A in vertical direction = 0 m/s (since the projectile was launched horizontally)
a = acceleration of the projectile = g = acceleration due to gravity = 9.8 m/s²
t = time of travel for projectile A = 3.0 seconds
Y = vertical displacement of projectile A = height of the cliff = h = ?
using the kinematics equation along the vertical direction as
Y = v₀ t + (0.5) a t²
h = (0) (3.0) + (0.5) (9.8) (3.0)²
h = 44.1 m

Explanation
Tycho Brahe who was born on 1546. He was an astronomer.Tycho Brahe spent 20 years in plotting the positions of the planets and he was among those astronomers who helped in giving the heliocentric model of the universe..
Answer:
+16 J
Explanation:
We can solve the problem by using the 1st law of thermodynamics:
where
is the change of the internal energy of the system
Q is the heat (positive if supplied to the system, negative if dissipated by the system)
W is the work done (positive if done by the system, negative if done by the surroundings on the system)
In this case we have:
Q = -12 J is the heat dissipated by the system
W = -28 J is the work done ON the system
Substituting into the equation, we find the change in internal energy of the system:
