A large balloon contains 233 L of neon at 22.0C and 760. Torr. If the balloon ascends to an altitude where the temperature is - 52.0C and the pressure is 511 torr, what is the volume in the balloon at the higher altitude?
Answer: The volume in the balloon at the higher altitude is 260 L
Explanation:
The combined gas equation is,
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 760 torr
[tex]P_2[/tex] = final pressure of gas = 511 torr
[tex]V_1[/tex] = initial volume of gas = 233 L
[tex]V_2[/tex] = final volume of gas = ?
[tex]T_1[/tex] = initial temperature of gas = [tex]22.0^0C=(22.0+273)K=295K[/tex]
[tex]T_2[/tex] = final temperature of gas = [tex]-52.0^0C=(-52.0+273)K=221K[/tex]
Now put all the given values in the above equation, we get:
[tex]\frac{760\times 233}{295}=\frac{511\times V_2}{221}[/tex]
[tex]V_2=260L[/tex]
The volume in the balloon at the higher altitude is 260 L

calculate the mass of sodium trioxocarbonate(iv) produced by the complete decomposition of 16.8g of sodium hydrogen trioxocabonate(iv)
Answer:
question for you how does this app work old tell me
2 moles or 168 g of sodium hydrogen trioxocarbonate produce 106 g of sodium trioxocarbonate. Thus 16.8 g of sodium hydrogen trioxocarbonate will produce 10.6 g of sodium trioxocarbonate.
What is decomposition?Decomposition is a type of chemical change in which the a compound decompose or break into its constituent compounds or molecules.
The decomposition of sodium hydrogen trioxocarbonate is written as follows:
[tex]2NaHCO_{3} \rightarrow Na_{2} CO_{3} + H_{2}O +CO_{2}[/tex]
According to this equation 2 moles or 168 g of sodium hydrogen trioxocarbonate produce 106 g or one moles of sodium trioxocarbonate. Molar mass of sodium bicarbonate is 84 g thus 2 moles are 168 g.
Thus, the mass of sodium trioxocarbonate formed from 16.8 g of sodium hydrogen trioxocarbonate is calculated as follows:
mass of product = 16.8 × 106 /168 g
= 10.6 g.
Hence, Thus 16.8 g of sodium hydrogen trioxocarbonate will produce 10.6 g of sodium trioxocarbonate.

what is the name for C3Cl8 and is it a covalent or polar covalent bond?
Answer:
Propane, octachloro- | C3Cl8 - PubChem
The name of C3Cl8 is octachloropropane. It is a covalent bond.
What are covalent bonds ?Covalent bonds are formed when two atoms share electrons. In the case of octachloropropane, the carbon atoms share electrons with the chlorine atoms. The electrons are shared unequally, so the bond is polar covalent.
The name octachloropropane is derived from the Greek words "octo" (eight) and "chloro" (chlorine). The prefix "octa" refers to the number of chlorine atoms in the molecule. The suffix "propane" refers to the three carbon atoms in the molecule.

Convert 3.55 moles Nacl to formula units
Answer:
2.14 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of NaCl = 3.55moles
Unknown:
Formula units of NaCl = ?
Solution:
A mole of substance contains the avogadro's number of particles. The number of particles could be protons, atoms, neutrons, formula units etc.
1 mole of substance = 6.02 x 10²³ formula units
3.55 mole of NaCl = 3.55 x 6.02 x 10²³
= 2.14 x 10²⁴ formula units

how many moles of carbon are in 3.0 moles of c6h12o6
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

Which action occurs in the third stage of cell division?
The nuclear membrane disappears.
The nuclear material of a cell is copied exactly.
The cell forms two nuclei.
The nuclear material separates, with half moving to either side of the cell.
Answers:
1. People generally experience rapid growth for a second time between the ages of 15 and 20
2. The endocrine system contains the pituitary, adrenal, and thyroid glands.
3. The nuclear membrane disappears in the third stage of cell division?.
Explanation 1:
Between the ages of 15 and 20, puberty causes the release of multiple hormones, which causes rapid growth among other things.
Explanation 2:
The reproductive system contains the ovaries (female) and testes (male).
The endocrine system contains the pituitary, adrenal, and thyroid glands.
The circulatory system contains three independent systems that work together, the heart (cardiovascular), the lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
The respiratory/pulmonary system contains the nose, mouth, throat (pharynx), voice box (larynx), windpipe (trachea) , airways (bronchi) , and lungs.
Explanation 3:
Mitosis is the process in cell division where the nucleus divides into two nuclei, each with an identical set of chromosomes.
Interphase: occurs when the cell begins to replicate the nuclear DNA material
Stage 1 - Prophase: chromosomes begin to undergo a condensation process that will continue until metaphase. The spindle also begins to form as the two pairs of centrioles move to opposite poles.
Stage 2 - Prometaphase: Chromosomes are pulled in opposite directions by microtubules growing out from both poles of the spindle until balanced.
Stage 3 - Metaphase: The centromeres of all the cell's chromosomes line up at the equator of the spindle.
Stage 4 - Anaphase: The chromosomes move away from one another to opposite poles of the spindle.
Stage 5 - Telophase and Cytokinesis: The chromosomes reach the poles, the nuclear membrane then reforms, and the chromosomes begin to decondense. This is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
Most of my sources say that the nuclear membrane occurs during prophase, but the stages are listed in this order. Regardless, your answer would be A. The nuclear membrane disappears.
