Answer:
Living things can have a minimum of one cell
Explanation:
Living things can have a minimum of one cell; these are called unicellular organisms. Some examples of unicellular organisms: bacteria, algae (plants), some fungi, and protozoa

Explanation:
When citric acid and baking soda react with one another, they change chemi- cally and form sodium ions, citric acid ions, carbon dioxide gas, and water. ... It also makes up the bubbles in carbonated drinks and is a gas we naturally exhale. Carbon dioxide gas is safe in the quantities produced in the activities.
Answer: 1.14
Explanation:
![HCl+NaOH\rightarrow NaCl+H_2O](https://tex.z-dn.net/?f=HCl%2BNaOH%5Crightarrow%20NaCl%2BH_2O)
To calculate the molarity of acid, we use the equation given by neutralization reaction:
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
are the n-factor, molarity and volume of acid which is ![HCl](https://tex.z-dn.net/?f=HCl)
are the n-factor, molarity and volume of base which is NaOH.
We are given:
![n_1=1\\M_1=?\\V_1=10.0mL\\n_2=1\\M_2=0.1M\\V_2=7.2mL](https://tex.z-dn.net/?f=n_1%3D1%5C%5CM_1%3D%3F%5C%5CV_1%3D10.0mL%5C%5Cn_2%3D1%5C%5CM_2%3D0.1M%5C%5CV_2%3D7.2mL)
Putting values in above equation, we get:
![1\times M_1\times 10.0=1\times 0.1\times 7.2\\\\M_1=0.072M](https://tex.z-dn.net/?f=1%5Ctimes%20M_1%5Ctimes%2010.0%3D1%5Ctimes%200.1%5Ctimes%207.2%5C%5C%5C%5CM_1%3D0.072M)
To calculate pH of gastric juice:
molarity of
= 0.072
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![pH=-log(0.072)=1.14](https://tex.z-dn.net/?f=pH%3D-log%280.072%29%3D1.14)
Thus the pH of the gastric juice is 1.14
