Answer:
Opposite.
Water exhibits negative charge near hydrogen, positive near oxygen.
This is why it is OPPOSITE.
Let me know if this helps!
Water is a polar compound because it exhibits opposite charges. Therefore, option C is correct.
What is polar compound ?The term polar compound is defined as the compound with distinct regions of positive and negative charge, as a result of bonding with atoms such as nitrogen, oxygen, or sulfur.
Water is a polar compound because the covalent bonds between hydrogen and oxygen in the water molecule are polar in nature. Any molecule with lone pairs of electrons around the central atom is polar compound.
In water there are two atoms are present that are oxygen and hydrogen. Hydrogen has positive charge while oxygen has negative charge,
Thus, Water is a polar compound because it exhibits opposite charges, option C is correct.

are TRUE? (select 2 answer choices).
A. Curly hair develops over time. It is not acquired at birth.
B. Curly hair can lead to harmful mutations in the body.
C. Curly hair results from a change in the gene that
codes for hair structure.
D. People with curly hair have different hair protein structures than people with
straight hair.
Answer here:
Answer:
A and D are the answers
Explanation:
the other two don't make sense
The statements C and D are correct, i.e., curly hair have different protein structure from straight hair and curly hair results from a change in the gene.
What is protein?Proteins are biomolecules made of amino acids. Proteins are very essential to all living things and contributes the body structure. Proteins are mainly up taken through diet and they are the main source of energy.
Hair is made of keratin protein. Keratin makes up our skin and nails too.Curly hair is originating by birth not developing over time. Curly hair is more likely to be occurring through inheritance.
The protein structure the hair follicle is some more bend for curly hair. Curly hair and straight hair originates from different gene traits. The gene type is inherited from the parents.
Hence, for people with curly hair have different protein structure and it result from a change in gene that code for hair structure. Thus options C and D are correct.

I'm having trouble understanding what "the difference in energy between the products and reactants from the surroundings" means. Can you help explain what this means? please
Answer:
The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.
Explanation:
Due to the absorption of energy when chemical bonds are broken, and the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in energy between products and reactants. By the Law of Conservation of Energy, however, we know that the total energy of a system must remain unchanged, and that oftentimes a chemical reaction will absorb or release energy in the form of heat, light, or both.

What is the molarity of 2 moles of a compound dissolved in 4 L of water?
A. 2 M
B. 0.5 M
C. 4M
D. 1 M
Answer:
[tex]\boxed {\boxed {\sf B. \ 0.5 \ M}}[/tex]
Explanation:
Molarity is a measure of concentration in moles per liter. The formula for calculating molarity is:
[tex]molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}[/tex]
There are 2 moles of a compound or the solute. There are 4 liters of water or the solution.
moles of solute= 2 mol liters of solution = 4 LSubstitute the values into the formula.
[tex]molarity = \frac{ 2 \ mol}{ 4 \ L}[/tex]
Divide.
[tex]molarity= 0.5 \ mol /L[/tex]
1 mole per liter is equal to 1 Molar, so the solution's molarity of 0.5 mol/L is equal to 0.5 M.
[tex]molarity = 0.5 \ M[/tex]
The molarity of the solution is 0.5 Molar and choice B is correct.

Substances that contain a transition metal can be oxidizing. The greater the number of oxidation of this metal, the greater the oxidizing character of the substance. In an industrial process in which the use of an oxidizing agent is necessary, only five substances are available: CaO, FeO, Cu₂O, Cr₂O₃ and KMnO₄.
The substance that should be used in this process, as it has a greater oxidizing character, is:
a) Cr₂O₃
b) Cu₂O
c) CaO
d) FeO
e) KMnO₄

A Questic
Is the following reaction feasible at 340K? Mg + ZnO -> MgO + Zn Enthalpy Data: Mg: 0 kJ/mol ZnO: -348 kJ/mol MgO:-602
kJ/mol Zn: 0 kJ/mol Entropy Data: Mg: 33 J/K mol ZnO: 44 J/K mol MgO: 42 J/K mol Zn: 27 J/K mol
A. No, it is not feasible because the Gibbs free energy change is negative.
OB. Yes, it is feasible because the Gibbs free energy change is negative.
C. No, it is not feasible because the Gibbs free energy change is positive.
D. Yes, it is feasible because the Gibbs free energy change is positive.
Answer:
No, it is not feasible because the Gibbs free energy change is positive
Explanation:
∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol
∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol
From;
∆G = ∆H - T∆S
∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]
∆G = 2.57 × 10^5 J/mol
Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.
Answer:
B. Yes, it is feasible because the Gibbs free energy change is negative.
