Answer:

Scientific Method

Explanation:

Science is empirical in nature. The entire purpose of science is to discover new knowledge.

The empirical research method in science all begins with gathering observations from phenomena. After that, the researcher formulates appropriate hypothesis which are rigorously tested.

The conclusions drawn from testing the original hypothesis validate or modify the original hypothesis.

Describe four effects that radiation can have on the human body.

Alinara [238K]

Answer:

There are many effects of radiation to the human body. (if you watch the 100, you'll see what happens)

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as

The equilibrium constant for the reaction 2NH3(g) N2(g) + 3H3(g) is Keq = 230 at 300°C. At equilibrium, what will be the value o

evablogger [386]

Answer:

230

Explanation:

Given equilibrium conditions, if a system is at equilibrium, this means the rate of a forward reaction becomes equal to the rate of a reverse reaction and the concentrations of each species become constant (stop to change).

This is defined by the equilibrium constant which defines the concentrations at equilibrium. For the given reaction, the equilibrium constant can be described as the ratio between the concentrations of products (raised to the power of their coefficients) and the concentrations of reactants (raised to the power of their coefficients):

$K_{eq}=\frac{[N_2][H_2]^3}{[NH_3]^2}$

Q, on the other hand, is a reaction quotient. It is used only to determine where the equilibrium will shift when the system is actually not at equilibrium. The expression or Q is exactly same, but concentrations used would be non-equilibrium concentrations. There are three cases:

$Q$ : in this case, equilibrium shifts towards the formation of products;
