On the line segment, each 'one' is divided into ten parts by small lines. Since the line segment is 3 full units long and each unit is 10 parts, the length of the line segment is known to the nearest tenth. The answer is 3.0
Answer:
B
Explanation:
The letter in this energy profile diagram of an exothermic change that signifies energy is B;
- An exothermic reaction is one in which heat is liberated to the surroundings.
- The surrounding becomes hotter at the end of the change.
- B is the enthalpy change of the reaction
- A is the activation energy
- C is the reactant
- D is the product
Answer:
Because time is independent of distance, and distance is dependent of time.
Explanation:
Usually, on any graph, the independent variable is plotted on the x-axis and the dependent variable is plotted on the y-axis. Because of this, time, which is independent (time happens regardless of any other factor), is on the x-axis while distance, which is the dependent variable (can only take place in time), is on the y-axis.
Your answer is A my friend as the atomic number of an atom is determined by the number of protons
The atmospheric pressure will be:
The pressure of the atmosphere resulting from the mercury column is 0.959 atm
What is atmospheric pressure?
The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.
Given: Height of mercury column = 729 mm Hg
To find: The pressure of the atmosphere
Calculation:
The atmospheric column resulting from the mercury column is calculated as follows:
1 atm =760 mm Hg
So, we can convert the 729 mm Hg to atm, and we get
Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm
