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.
A) electrolyte the others either describe a process, the opposite, or a whole different thing
Answer:
455.4 g
Explanation:
Data given:
no. of moles of (NH₄)₂SO₄= 3.45 mol
mass of (NH₄)₂SO₄ = ?
Solution
Formula will be used
no.of moles = mass in grams / molar mass
Rearrange the above equation for mass
mass in grams = no. of moles x molar mass . . . . . . . . (1)
molar mass of (NH₄)₂SO₄
molar mass of (NH₄)₂SO₄ = 2(14 + 4(1)) + 32 + 4(16)
molar mass of (NH₄)₂SO₄ = 2 (14 +4) + 32 + 64
molar mass of (NH₄)₂SO₄ = 2 (18) + 32 + 64
molar mass of (NH₄)₂SO₄ = 36 + 32 + 64 = 132 g/mol
Put values in equation 1
mass in grams = 3.45 mole x 132 g/mol
mass in grams = 455.4 g
So,
mass of (NH₄)₂SO₄ = 455.4 g
Animals with larger weights compensate for the large force they exert on the ground, by having a large footprint area in order to reduce the pressure of their feet on the ground.
<h3>Why do animals with large weight have large feet?</h3>
Large animals such as elephants, lions, hippopotamus, etc, usually have a large foot print area compared to smaller animals.
This larger footprint area helps to support their weight.
The weight of these animals exerts a force as well as pressure on the ground.
Pressure, force and area are related by the equation below:
The larger the area, the smaller the pressure.
In order to compensate for the large force they exert on the ground, larger animals possess a large footprint area in order to reduce the pressure of their feet on the ground.

Answer:
Two-electron.
Explanation:
Hello!
In this case, since the half-reaction by which chlorine is reduced to aqueous chloride ion is:
We can see each chlorine undergo a decrease of electrons by 1, it means that, since there are two chlorine atoms undergoing an electron decrease, we write:
Which means this is a two-electron process.
Best regards!
