Answer:
is D
Explanation:
because one positive object and one negative object.
An antacid that lowers the amount of stomach acid
1)The state or phase in which most ionic compounds occur will be a solid state or phase. This will make the correct answer A.
2) The compound Co is an example of a covalent compound. This will make the answer to be D.
Answer:
12 atm
Explanation:
First, let us convert Celcius into Kelvin: 28.0 °C = 301.15 K and 129.0 °C = 402.15 K
For this question we must employ the Combined Gas Law: , where is the initial pressure and is the new pressure.
We know that intitially, P=9 atm, V=30 L, and T=301.15K. From our problem, only temperature and pressure changes, while the number of moles, volume and the gas constant, R, stay the same, so they are irrelevant.
Thus, the filled out Combined Gas Law would be:
=, where the volume, moles of gas, and R are cancelled out.
We can manipulate this equation to derive the new pressure. We find that
9atm≈0.74885.
This means that
≈9/0.74885≈12 atm
Answer:
<h3>false ..</h3>
since...
- NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions.
