What do all oxygen atoms have in common
Gwar [14]

Answer: An atomic number of 8

Explanation:

All oxygen atoms have an atomic number of 8 in common, but could differ in mass number in their isotopes.

Examples of oxygen atoms are O16, O17, and O18. They all have an atomic number of 8, but different mass numbers of 16, 17, and 18 respectively. Thus, they are isotopes of oxygen.

You add 168.90 grams of NaCl to a container and then you add 616.00 grams of water to that same container What is the weight per
erma4kov [3.2K]

Answer:

The weight percent of NaCl in the container​ is 21.5%

Explanation:

Given that,

Mass of NaCl = 168.90 gram

Mass of water = 616.00 grams

We need to calculate the weight percent of NaCl in the container​

Using formula of percentage of weight

weight\ \%\  of\ component\ of\ the\ solution =\dfrac{weight\ of\ the\ component\ in\ the\ solution}{total\ weight\ of\ the\ solution}\times100

Put the value into the formula

weight\ \%\  of\ component\ of\ the\ solution =\dfrac{168.90}{168.90+616.00}\times100

weight\ \%\  of\ component\ of\ the\ solution=21.5\%

Hence, The weight percent of NaCl in the container​ is 21.5%

A 6.0 mol sample of C3H8(g) and a 20. mol sample of Cl2(g) are placed in a previously evacuated vessel, where they react accordi
gladu [14]
2 CH₃CH₂CH₃ + 2 Cl₂ →  CH₃CH(Cl)CH₃ + CH₃CH₂CH₂Cl + 2 HCl
so according to balanced equation we notice that:
2 mole of propane reacts with 2 moles of Cl₂, so 6 moles of propane will need to react completely with 6 moles Cl₂ (This mean Cl₂ present in excess and propane is the Limiting reagent)
2 mole C₃H₈ gives 2 moles HCl
6 moles C₃H₈ gives ? moles HCl
by cross multiplication we have 6 moles of HCl formed
