Is a physical change A. Forming a mixture B. Burning wood C. Food turning into waste in the intestines D. Turning solid sodium and chlorine gas into salt?
A physical change is A. Forming a mixture. Physical changes involve alterations in form or appearance without changing the chemical composition of the substances involved. In contrast, burning wood (B) and the chemical reaction that creates salt from sodium and chlorine gas (D) are chemical changes, while food turning into waste (C) involves both chemical and biological processes.

What element's atomic mass is 35.453?

How many chlorine has isotopes?
Chlorine has a lot of different isotopes but the 2 stable ones are chlorine 35 and chlorine 37
How does Chlorine affect your body?
According to a Belgian study that was released in 2003, certain irritants called trichloramines are released any time chlorinated water reacts with organic materials (such as sweat or urine) from people.³ Trichloramines are believed to initiate a biological process that effectively destroys the cellular barriers surrounding the lungs. Children exposed to large amounts of chlorine could potentially suffer asthmatic attacks. In one research study, rats exposed to chlorine and chloramines developed tumors in their kidneys and intestines. Chlorine can irritate severely, even burn, skin exposed directly to it. It can irritate and burn the eyes and throat as well.
What atoms are in chlorine?
Chlorine (Cl) atoms make up the element chlorine.
What halogen is in table salt?
Chlorine
Is there chlorine in chlorine dioxide?
Chlorine dioxide is a different chemical compound from chlorine. While they both contain the element chlorine, there is no chlorine in the form of Cl2 in chlorine dioxide. Chlorine dioxide (ClO2) is a strong oxidizing agent used for water treatment and disinfection.
What is chlorines mass number?
Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.
What is the name for Cl2 in chemistry?
Cl2 is chlorine. Chlorine exists as a diatomic molecule.
What is the difference between a chlorine atom and a chlorine molecule?
A chlorine atom is a single chlorine atom with the chemical symbol Cl. A chlorine molecule is composed of two chlorine atoms bonded together, forming Cl2. Chlorine atoms are highly reactive, while chlorine molecules are more stable.
Why chlorine is called chlorine?
Chlorine is called chlorine because it is from the greek word chloros which means "lime-green gas"
What is free chlorine in a pool?
Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.
How do you calculate chloramines?
Chloramines can be calculated by the formula: Chloramines = Total Chlorine - Free Chlorine. Total chlorine is the sum of free chlorine and combined chlorine (chloramines). By subtracting the free chlorine level from the total chlorine level, you can determine the amount of chloramines present in the water.
