<span>H-1 means that the isotope has mass number 1: it has 1 proton. H-2 means that the isotope has mass number 2: so it has 1 proton and 1 neutron. H-3 means the isotope has 1 proton and 1 neutron. As you see all the isotopes have the same number of protons (atomic number), therefore they also have the same number of electrons. What defines (differentiate) isotopes is the number of electrons. So, fill the table such that the number of protons and electrons is 1 for all the isotopes, and the number of neutrons are 0 for H-1, 1 for H-2, and 2 for H-3.</span>
it is more dense think about how heavy the water feels you go down you feel more pressure so it is denser
There is most likely to be a lot of sinking cold air, or fog. When the water in the air condenses (or cools) quickly, this is likely to happen.
I hope this helps!

Answer:
Acid ammonium carbonate // Ammonium bicarbonate.
Explanation:
Hello, a 4 is missing in the fist H, thus:
The presence of the hydrogen between the ammonium and the carbonates characterizes the salt as an acid salt, so you could name it as acid ammonium carbonate or ammonium bicarbonate (similar to the sodium bicarbonate which is .
Best regards.
The reaction between methane gas and chlorine gas to form hydrogen chloride and carbon tetrachloride, all in their gaseous form can be expressed through the chemical reaction below.
CH₄ + 4Cl₂ --> 4HCl + CCl₄
Let us assume that all the involved gases behaves ideally such that each mole of the gas is equal to 22.4 L.
Through proper dimensional analysis, the volume of the produced hydrogen chloride is calculated,
V(HCl) = (1.69 mL CH₄)(1 L CH₄/ 1000 mL CH₄)(1 mol CH₄/22.4 L CH₄)(4 mols HCl/1 mol CH₄)(22.4 L HCl/1 mol HCl)(1000 mL/1 L)
V(HCl) = 6.76 mL
<em>ANSWER: 6.76 mL</em>
