Answer:
Sour taste, low pH, and dissolves metals
Explanation:
Acids have a pH below 7.0. Acids turn litmus paper red as they have pH below 7.0. Bases on the other hand have pH above 7.0. Water has a neutral pH of 7.0.
Acids have a sour taste. For example citric acids found in lemons make it sour. Vinegar has acetic acid which makes it sour.
Acids dissolve metals to form salts and hydrogen gas
2HCl + Zn → ZnCl₂ + H₂

Answer:
Explanation:
I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.
The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.
Molarity =
To find the right mix that will give us 8M carbon chloride solution, let's explore how to figure out the appropriate volume.
Clearly given is the mass of the compound, convert to number of moles.
Number of moles =
Molar mass of carbon chloride(CCl₄) = 12 + 4(35.5) = 154g/mol
Number of moles = = 0.57moles
To find the volume;
8 =
volume = 0.071L or 71mL
Answer:
<h2>11.2 g</h2>
Explanation:
Given,
Mass of P = 4.89 g
Molar mass of = 30.9738 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction shown below as:-
4 moles of P on reaction forms 2 moles of diphosphorus pentoxide
Also,
1 mole of P on reaction forms 2/4 mole of diphosphorus pentoxide
0.158 moles of P on reaction forms moles of diphosphorus pentoxide
Moles of diphosphorus pentoxide = 0.079 moles
Molar mass of diphosphorus pentoxide = 141.9445 g/mol
<u>Mass = Moles * Molar mass = 0.079 moles * 141.9445 g/mol = 11.2 g</u>
That it is number 17 35.45 it's period is 3.
