Explanation:
hope it helps ;-;
It is best defined as a "proposed explanation".
A scientific hypothesis is a tentative explanation for an observation or phenomenon that can be tested scientifically. It's an educated guess about the relationship between two or more variables. For instance, stating that plants require sunlight to grow is a hypothesis that can be tested.
A scientific hypothesis is best defined as a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation and/or experimentation. In other words, a scientific hypothesis is an educated guess about the possible relationship between two or more variables. For example, if you observed that a plant did not grow well without sunlight, you could form a hypothesis that plants need sunlight to grow. You could then test this hypothesis through an experiment.

Answer:
In a right triangle the biggest angle is 90°.
Then the two smaller angles sum up 180° - 90° = 90 °.
Now you can use this equation: 3x + 6 + 2x - 1 = 90 and solve for x:
5 x + 5 = 90
5x = 85
x = 85/5
x = 17
Then, the smallest angle is 2(17) - 1 = 33°

B. increased energy
C. increased particle collisions
The correct reason behind the increased rate of the reaction with the increase in these parameters is the increased collisions between the particles.
Option C.
Molecules that take part in a chemical reaction are present in a common medium. This medium contains all the molecules and the enzymes required for the reaction. The reaction that takes place in the medium is initiated by the collision between the reactant molecules which dispose into the reaction. Thus, increasing the rate of collision between the molecules increases the rate of the reaction.
Increasing the temperature increases the kinetic energy of the molecules which in turn increases the rate of collision.
Increase in the pressure reduces the volume, thereby bringing the molecules together, increasing collision.
Increase in concentration increases the number of molecules per unit volume, thereby increasing the rate of collision.
Answer:
increased particle collisions
