Answer:

B

Explanation:

Answer: Boron

Explanation:

Answer: Boron.

Explanation: The trend of atomic radius increases as we go from right to left on a periodic table, so since Boron is further left, Boron has a slightly larger radius.

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.

Answer:

eight

Because the noble gases are the least reactive of all elements, their eight valence electrons are used as the standard for nonreactivity and to explain how other elements interact.

Propane, octachloro- | C3Cl8 - PubChem

The name of C3Cl8 is octachloropropane. It is a covalent bond.

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.

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.

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.

Answer:

A) 1 & 2 only

Explanation:

Seeing that the chemicals present are in question one I take it you are asking about that question.

Decreasing the concentration causes a decrease in reaction process and also the total amount of product you would get out of the given reaction

Decreasing the temperature causes the molecules in this reaction to become less excited or reactive, thus causing the reaction to slow down

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.

The extraction is done by electrolysis. The ions in the aluminum oxide must be free to move so that electricity can pass through it. Aluminum oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. Aluminum oxide does not dissolve in water, but it does dissolve in molten cryolite.
