T = final temperature of the block
T₀ = initial temperature of the block = 23.4 °C
Q = energy lost from the wooden block = - 759 J
c = specific heat capacity of wood = 1.716 J/(g °C)
m = mass of the wooden block = 27.2 g
Heat lost from the block is given as
Q = m c (T - T₀)
inserting the values
- 759 = (27.2) (1.716) (T - 23.4)
T = 7.1 °C
Answer:
Explanation:
Hello there!
In this case, according to the given STP (standard pressure and temperature), it is possible for us to realize that the equation to use here is the Avogadro's law as a directly proportional relationship between moles and volume:
In such a way, given the initial volume and both initial and final moles, we can easily compute the final volume as shown below:
Best regards!
The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
<h3>What is a triangle?</h3>
A triangle can be defined as a one of the plane shapes which has three sides and three angles
So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

A. True.
Very true. The quicker or slower the reactants are used up the faster or slower the rate of reaction, and the faster or slower the products are formed, the faster or slower the rate of reaction.
Answer:
Because the neutrons equal the number of protons
Explanation:
So if u have 16 protons u have 16 neutrons
