Answer:
the correct answer is b antifreeze protects the radiator during summer in winter.
Explanation:
Antifreeze is (typically mixed with water) to help manage the engine during extreme temperatures. As the temperature fluctuates between hot and cold coolant is distributed throughout the engine block to sustain even operating temperature.
Reactants are the substances that undergo changes and the new substance created from it is called products.
Answer:
cfcl3
Explanation:
When the cfcl3 in the atmosphere is hit by UV rays from the sun, it decomposes to Cl atoms. These Cl atoms then react with the ozone producing O2 and ClO. The ClO bombard with O atoms splitting the ClO up and the free Cl atom again bonds to another O3 molecule hence reducing it. One ClO can reduce several O3 molecules (up to 100,000) creating an ozone hole.
2Cl + O3 → 2ClO + 2O2
2ClO + 2O → 2Cl + 2O2
