8 0

Answer: B2H6 (g) + 3O2 (g) → B2O3 (s) + 3H2O (g) (ΔH = -2035 kJ/mol) 3H2O (g) → 3H2O (l) (ΔH = -132 kJ/mol) 3H2O (l) → 3H2 (g) + (3/2) O2 (g) (ΔH = 858 kJ/mol)

Which among the following statements is FALSE? Group of answer choices None of the above A liquid has a definite volume; but it
Vesna [10]

Answer: None of the above statements is false.

Explanation:

In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.

In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.

In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.

Thus, we can conclude that none of the given statements are false.

Write the full symbol for the isotope of oxygen having 8 neutrons.​
Helen [10]

Answer:

Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).

Which units express specific heat capacity?
mixer [17]

Answer : The correct option is \frac{J}{g^oC},\frac{J}{gK},\frac{cal}{g^oC},\frac{cal}{gK}.

Explanation :

Specific heat capacity : It is defined as the amount of heat required to raise the temperature of one gram of substance by one degree Celsius.

Formula used :

q=mc\Delta T\\c=\frac{q}{m\Delta T}

where,

q = heat required

m = Mass

c = specific heat capacity

\Delta T = change in temperature

The unit of heat are expressed in terms of Joules, calories.

The unit of temperature are expressed in terms of degree Celsius, kelvin.

It is expressed as \frac{J}{g^oC},\frac{J}{gK},\frac{cal}{g^oC},\frac{cal}{gK}.

What do voltage-gated ion channels open in response to?.
Pavlova-9 [17]

Answer:Voltage-gated channels open (activate) in response to changes in membrane potential because the electric field acts on the channel to change its protein conformation (or state). It is voltage-gated sodium (Na+) channels that initiate action potentials and voltage-gated K+ channels that cause them to end.
