Answer:

The false statement is option A.

Explanation:

A rare isotope of carbon is carbon-14. The carbon-14 is radioactive and decays to produce nitrogen-14 and an electron. As carbon-14 is radioactive, it decays at a similar rate possessing a half-life of about 5700 years. The isotope is found in all the living things and is generally used to find the age of remains. The process of finding the age of the remains is known as radiocarbon dating. However, the carbon-14 is not a stable component, and this is the reason why it undergoes radioactive decay.

The false is A

as C-14 is an unstable isotope that is radioactive and is present in all living things i can be used to carbon date things 

hope that helps

A family of four lives in a three-bedroom house and uses an average of 900 kWh of electricity per month. The family cools their
agasfer [191]
<h2>Answer:</h2><h2>The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months = 19.4 %</h2>

Explanation:

Average electricity consumed per month = 900 kWh

The family cools their house for three months during the summer with two window-unit air conditioners

The power consumed by one window-unit air conditioners = 350 kWh

The power consumed by two window-unit air conditioners = 350(2) = 700 kWh

Power consumed for two air conditioners for the three summer months = 700 (3) = 2100 kWh

Total power consumed for 1 year = 900 (12) = 10800kWh

The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months = \frac{2100}{10800}100 = 19.4 %

When the stabilized state of an equilibrium system is altered, further chemical reactions begin until a new equilibrium is reach
Nezavi [6.7K]
The answer is a. True. This is also known as the Le Chatelier's principle or The Equilibrium Law which states that if a chemical reaction is at equilibrium and then experiences changes in the condition of the reaction such as changes in concentration, pressure, or temperature of products or reactants, the system will naturally shift to achieve a new equilibrium state.
