Answer: The hydroxide concentration of this sample is 3.85\times 10^{-7}

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

K_w=[H^+]\times [OH^-]

7.7\times 10^{-14}=[H^+]\times [OH^-]

As [H^+]=[OH^-]

2[OH^-]=7.7\times 10^{-14}

[OH^-]=3.85\times 10^{-7}

Thus hydroxide concentration of this sample is 3.85\times 10^{-7}

Which is true according to the law of conservation of energy?
alexandr1967 [171]

Answer: E)  In a closed system, the total energy always remains constant.

Explanation: For every system, the law of conservation of energy is applicable which states that the energy of the system remains conserved. Energy can neither be created nor destroyed.

A closed system is one which can exchange energy with the surroundings but not mass. Thus if a system absorbs energy, the equivalent amount of energy is lost by surroundings, thus the total energy remains constant.

If a system loses energy, an equivalent amount of energy is gained by surroundings, thus the total energy remains constant.

Which is a nonpolar molecule?
dedylja [7]

Answer:

Explanation:

A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents. The answer is hydrogen cyanide.

32,500 joules are used to boil a sample of water at its melting point what is the mass of the water?
Ivenika [448]

Answer:

43.18 gm

Explanation:

Heat of fusion of water at 0° C is 334  j/gm

 then you have to heat the water to boiling point (100 C)

    specific heat of water is 4.186 j/g-c

x = grams of water

x ( 334 + 4.186 (100) ) = 32500

x = 43.18 gm
