Answers

Answer 1

Answer:

Arsenic-tolerant GFAJ-1 bacteria were reported to have replaced some of the phosphorus (P) in their DNA with arsenic. ... These bacterial cells were very efficient at using the small amount of available phosphate in preference over the easily available arsenic. so yes.

Answer:

Potassium Hydroxide Solution =

or

Potassium Hydroxide =

Answer:  Potassium Hydroxide (KOH)

Explanation:

Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.

As it is in the question, we can map the reactants and product:

Reactants                   Product

Ammonium                 Ammonia

Sulfate                         Sulfate

________                   Potassium

________                    Water

Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.

This becomes clear when we consider the net ionic equation:

Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water

if we write this a balanced chemical equation:

(NH₄)₂SO₄   +  2KOH  →  K₂SO₄ + 2NH₃ + 2H₂O

if we write the reaction as an ionic equation

2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O

if we remove the ions that appear on both the reactant and product side (spectator ions)

2NH₄⁺ + 2OH⁻ → + 2NH₃ + 2H₂O

Which option correctly describes the pattern of valence electrons on the periodic table? (1 point)
o The number of valence electrons increases from right to left.
O The number of valence electrons increases from left to right.
O The number of valence electrons increases from bottom to top.
O The number of valence electrons increases from top to bottom.

Answers

Answer:

The number of valence electrons increases from left to right.

Explanation: The number of valence electrons increases going across a period, or row in the periodic table, for example, group 1 elements have 1 valence electrons and group 2 elements have have 2.

Which of the following would not be made in a ribosome?

Answers

Answer:

cholesterol(lipid)

Explanation:

Ribosomes are called PROTEIN FACTORY

Ribosomes are involved in protein synthesis

Any metabolite or substance protein in nature can be synthesized on ribosomes

enzymes are protein in  natureantibodies are y shaped protective proteinswater soluble hormones are also amine or protein in nature

Since they are protein in nature hence can be synthesized on ribosome.

CHOLESTEROL IS LIPID IN NATURE

LIPIDS ARE NOT proteins and cannot be SYNTHESIZED ON RIBOSOME

An atom of radium (Ra) forms a monatomic ion.
Which ion does it most likely form?
a- Ra2-
b- Ra-
c- Ra2+
d- Ra+

Answers

Answer:

The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s

2

It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.

Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s

2

will lose the two 7s electrons to form the cation with +2 charge.

Well, SCl2 is known, so is disulfur dichloride… Cl−S−S−Cl …and BOTH these species are molecular… On the other hand, lithium chloride, an ionic salt, is decidedly non-molecular, and consists of an infinite array of lithium and chloride ions held together by strong electrostatic forces ….. and thus we would expect the salt to have the much higher melting point….
