The answer is Safety.
Answer:
Carbon dioxide is a new product formed from the reaction between calcite and HCl
Explanation:
Calcite is a mineral with the chemical formula CaCO₃. Hydrochloric acid reacts with calcite to liberate carbon dioxide and form calcium chloride and water. The equation of the reaction is given below:
CaCO₃ + HCl ----> CaCl₂ + H₂O + CO₂
In a chemical reaction or change, new products are formed which are different from the original elements or compounds reacting.
Since the carbon dioxide gas, calcium chloride and water are entirely new products formed from calcite and hydrochloric acid, the reaction between calcite and HCl is a chemical reaction.
Answer:A
Explanation:
Carbon dioxide is a new substance created from the calcite and hydrochloric acid
A. By constricting the blood vessels
B. By dilating the blood vessels
C. By causing plaque buildup in the arteries
D. By causing blood clots in the arteries
Smoking have contributed to the patient's hypertension by constricting the blood vessels. Correct answer: A The chemical in the cigarettes -nicotine causes the blood vessels to constrict or narrow and this limits the amount of blood that flows to your organs, condition known as hypertension.
Smoking causes constriction of blood vessels that result in hypertension.
Further Explanation:
Smoking is the major cause of death in most of the country. It causes many severe diseases named as cardiovascular disease, lung cancer, bronchitis, cough, pneumonia. Hypertension is a long term disease that occurred due to high blood pressure. It is also referred to as a silent killer because it doesn’t have any signs and symptoms.
Smoke consists of harmful substances and chemicals, which cause inflammation in the lungs. Because of this inflammation, lungs release mucus and cause severe problems. They cause a major disease named as atherosclerosis. In this disease, the wall and lining of the arteries became thick. Also, the abruption of oxygen into the blood is decreased because of the harmful chemicals which are present in a cigarette. Chemicals present in the smoke of citrate cause constriction of the blood vessel. That’s how smoking contributes to high blood pressure.
