1. 5
2. 2
3. 3
4. 6
Answer:
Of oxygen would be 6 moles (4).
Explanation:
Since it is in a bracket you have to multiply 3 and tge 2 to get 6 oxygens.

How are ionic compounds named?
Answer:
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.
Explanation:
Hope this helps.
A 2.52 L container of oxygen gas at 28.6 °C is heated to 45.9 °C. Assuming that the volume of the container can vary, what is the new volume of the gas?
Answer:
4.04433566 L (433566 repeating)
Explanation:
2.52 is divided by 28.6 is 0.0881118 (881118 repeating). multiply 0.0881118 (881118 repeating) by 45.9 to get 4.04433566 L (433566 repeating).

How many moles of O2 are needed to burn 2.56 moles of CH3OH?
Answer:
[tex]n_{O_2}=3.84molO_2[/tex]
Explanation:
Hello!
In this case, since the combustion reaction of methanol is:
[tex]CH_3OH+\frac{3}{2} O_2\rightarrow CO_2+2H_2O[/tex]
In such a way, since there is 1:3/2 mole ratio between methanol and oxygen, we can compute the moles of oxygen that are needed to burn 2.56 moles of methanol as shown below:
[tex]n_{O_2}=2.56molCH_3OH*\frac{\frac{3}{2}molO_2}{1molCH_3OH} \\\\n_{O_2}=3.84molO_2[/tex]

To determine the density of an irregularly shaped object, a student immersed the object in 32.2 mL of water in a graduated cylinder, causing the level of the water to rise to 37.8 ml. If the object had a mass of 12.4 g, what is the density of the object?
O 0.32 g/mL
O 1.4 g/mL
O 3.4 g/mL
O 2.2 g/mL
Help quick right answer gets brainliest !!
Answer:
Explanation:
2.2 g/mL is the answer.
The free flow of electrons is responsible for
Answer:
An electrical phenomenon is caused by flow of free electrons from one atom to another. The characteristics of current electricity are opposite to those of static electricity. Wires are made up of conductors such as copper or aluminum.

You have 3.00 L of a 3.12 M solution of NaCl(aq) called solution A. You also have 2.00 L of a 2.00 M solution of AgNO3(aq) called solution B. You mix these solutions together, making solution C.
Calculate the concentration (in M) of Ag+ ions in solution C.
Answer:
[tex]M=0.8M[/tex]
Explanation:
Hello!
In this case, since the presence of silver ions is in AgNO3 only, we can compute their moles by using the volume and concentration of the corresponding salt:
[tex]n_{Ag^+}=2.00L*2.00\frac{mol}{L}=4molAg^+[/tex]
Next, since the total volume of solution C is 5.00 L, the required concentration of silver ions turn out:
[tex]M=\frac{4.00mol}{5L} =0.8M[/tex]

1. What kinds of metals are REALLY reactive? why?
2. What kinds of non-metals are REALLY reactive? why?
3. What group on the periodic table doesn’t react at all? why?
Answer:
1. Alkali metals (group 1)
2. halogens (Group 17)
3. noble gasses (group 18)
Explanation:
1. alkali metals only have one valence electron meaning that they really want to lose that one valence electron to get a full octet.
2. halogens have 7 valence electrons meaning that they just need to gain 1 to get a full octet.
3. Nobel gasses already have a full octet meaning that they don't want to react. (atoms only react to get a full octet)
I hope this helps. Let me know if anything is unclear.
What effect does the transfer of electrons have on the nuclei of the atoms involved?
Answer:
Chemical processes have no effect on the nucleus otherwise we would be in deep truble. GOOD LESSONS ♡
