A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

45.7 * 32.5 = P_{2} * 4.1

1485.25 = 4.1P_{2}

P_{2} = \frac {1485.25}{4.1}

P_{2} = 362.26

Final pressure, P2 = 362.26 kPa

What is the term used for the elements and compounds before a chemical reaction takes place?
alexandr1967 [171]

Explanation:

Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.

And, when the chemical reaction takes place between the given elements and compounds then they change into products.

For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.

But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.

N a pond, tadpoles eat algae and fish eat the tadpoles. around the pond, grasshoppers eat grass and, at night, are preyed upon b
Dima020 [189]
I believe that in this community the tadpoles are: the primary consumers. A n ecological community is the set of all populations of all species found in a given place. Primary consumers are mainly herbivores which feed on plants; which are the primary producers of all the energy in an ecosystem. In this case the tadpoles eat algae (primary producer) thus they are primary consumer.

Family and twin studies examining the rates of autism spectrum disorder have provided compelling evidence for a genetic influenc
TEA [102]

In fact, the concordance rate of autism spectrum disorder was twice in identical twins that of non-twin siblings.

It has been shown that genetic has a huge influence on the development of autism spectrum disorder and that autism in identical twins was 13 times that of the general population. This suggest that environmental factors in the womb are the major factors that contribute.
